70-642 Configuring Windows Server 2008 Network Infrastructure

Questions and Answers

1.

A user in your organization complains that she cannot connect to any network resources. You run the Ipconfig command on her computer and find that the address assigned to the Local Area Connection is 169.254.232.21. Which of the following commands should you type first? Ch1 L1
- A.
  
  Ipconfig /renew
- B.
  
  Ping 169.254.232.21
- C.
  
  Tracert 169.254.232.21
- D.
  
  Arp -a
Correct Answer
A. Ipconfig /renew

Explanation
A. Correct: The address shown is an APIPA address, which is assigned automatically to a DHCP client if a DHCP server cannot be found. An APIPA address usually results in a loss of connectivity to network resources. To fix the problem, you should first attempt to obtain a new address from a DHCP server. To do that, use the Ipconfig /renew command.
B. Incorrect: This command will merely verify that you can connect to your own address. It will not help establish network connectivity.
C. Incorrect: This command will merely verify that you can trace a path to your own address. It will not help establish network connectivity.
D. Incorrect: This command displays the list of IP address-to-MAC address mappings stored on the computer. It will not fix any problems in network connectivity.

Which of the following address types is best suited for a DNS server? Ch1 L1
- A.
  
  DHCP-assigned address
- B.
  
  APIPA address
- C.
  
  Alternate configuration address
- D.
  
  Manual address
Correct Answer
D. Manual address

Explanation
A. Incorrect: You should not configure a DNS server as a DHCP client. A DNS server needs the most stable address available, which is a manually configured static address.
B. Incorrect: An APIPA address is an address that signifies a network problem. It is not a stable address and should not be assigned to a server.
C. Incorrect: An alternate configuration is not a stable address because it can be replaced by a DHCP-assigned address. You should assign the most stable address
type—a static address—to a DNS server.
D. Correct: The addresses of infrastructure servers such as DHCP and DNS servers should never change. Therefore, these server types should be

How many computers can you host in an IPv4 network whose address is 172.16.0.0/22? Ch1 L2
- A.
  
  512
- B.
  
  1024
- C.
  
  510
- D.
  
  1022
Correct Answer
D. 1022

Explanation
A. Incorrect: A /23 network can support 512 addresses but only 510 devices.
B. Incorrect: A /22 network can support 1024 addresses but only 1022 devices.
C. Incorrect: A /23 network can support 510 devices, but a /22 network can support more.
D. Correct: A /22 network can support 1024 addresses but only 1022 devices because two addresses in every block are reserved for network communications.

You work as a network administrator for a research lab in a large company. The research lab includes six computers for which central computing services has allocated the address space 172.16.1.0/29. You now plan to add 10 new computers to the research network. Company policy states that each network is granted address space only accordingto its needs. What should you do? Ch1 L2
- A.
  
  Ask to expand the network to a /28 address block.
- B.
  
  Ask to expand the network to a /27 address block.
- C.
  
  Ask to expand the network to a /26 address block.
- D.
  
  You do not need to expand the network because a /29 network is large enough to support your needs.
Correct Answer
B. Ask to expand the network to a /27 address block.

Explanation
A. Incorrect: A /28 network supports 16 addresses and 14 computers. You need to support 18 addresses and 16 computers.
B. Correct: You need to support 18 addresses and 16 computers. A /27 network supports 32 addresses and 30 computers. This is the smallest option that provides you
with the address space you need.
C. Incorrect: A /26 network supports 64 addresses and 62 computers. This is larger than you need, so it would violate company policy.
D. Incorrect: The current /29 network supports eight addresses and six computers. It cannot support the 16 computers you need.

You want an IPv6 address for a server that you want to connect to the IPv6 Internet. What type of IPv6 address do you need? Ch1 L3
- A.
  
  A global address
- B.
  
  A link-local address
- C.
  
  A unique local address
- D.
  
  A site-local address
Correct Answer
A. A global address

Explanation
A. Correct: Global addresses are routable addresses that can communicate directly with IPv6-only hosts on public networks. This is the kind of address you need if you want a static IPv6 address to which other computers can connect from across the IPv6 Internet.
B. Incorrect: A link-local address is not routable and cannot be used on a public network.
C. Incorrect: A unique-local address is routable but cannot be used on a public network.
D. Incorrect: A site-local address is a version of a unique local address, but these address types

You want to create a test IPv6 network in your organization. You want the test network to include three subnets. What type of IPv6 addresses do you need? Ch1 L3
- A.
  
  Global addresses
- B.
  
  Link-local addresses
- C.
  
  Unique local addresses
- D.
  
  Site-local addresses
Correct Answer
D. Site-local addresses

Explanation
A. Incorrect: You would need global addresses only if you wanted your network to connect to the public IPv6 network.
B. Incorrect: Link-local addresses are not routable so they would not allow your subnets to intercommunicate.
C. Correct: Unique local addresses resemble private address ranges in IPv4. They are used for private routing within organizations.
D. Incorrect: Site-local addresses were once defined as a way to provide routing within a private network, but this address type has been deprecated.

After the address of a certain client computer is updated, you notice that a local DNS server is resolving the name of the computer incorrectly from cached information. How can you best resolve this problem? CH2 L1
- A.
  
  At the DNS server, type the command dnscmd /clearcache.
- B.
  
  Restart the DNS Client service on the client computer.
- C.
  
  At the client computer, type ipconfig /flushdns.
- D.
  
  Restart all DNS client computers.
Correct Answer
A. At the DNS server, type the command dnscmd /clearcache.

Explanation
A. Correct: This command flushes the DNS server cache. If you know that a DNS server is responding to queries with outdated cache data, it’s best to clear the server cache. This way, the next time the DNS server receives a query for the name, it will attempt to resolve that name by querying other computers.
B. Incorrect: Restarting the DNS Client service will flush the DNS client cache on the computer in question. It won’t affect the way the DNS server responds to the query for that computer’s name.
C. Incorrect: Typing ipconfig /flushdns simply clears the DNS client cache. It won’t affect the way the DNS server responds to the query for that computer’s name.
D. Incorrect: Restarting all client computers will not fix the problem. It merely has the effect of clearing the DNS client cache on all computers. This could fix problems related to outdated client cache data, but it will not fix the problem on the DNS server itself.

You are working on a Windows Server 2008 computer named WS08A. You cannot connect to computers running Windows XP on the local network by specifying them by name in a UNC path such as \\computer1. What can you do to enable your computer to connect to these computers by specifying them in a UNC? CH2 L1
- A.
  
  Enable IPv6 on WS08A.
- B.
  
  Disable IPv6 on WS08A.
- C.
  
  Enable Local Link Multicast Name Resolution (LLMNR) on WS08A.
- D.
  
  Enable NetBIOS on WS08A.
Correct Answer
D. Enable NetBIOS on WS08A.

Explanation
A. Incorrect: When you enable IPv6 on a computer running Windows Server 2008, no extra functionality is enabled in connections to a computer running Windows XP.
B. Incorrect: IPv6 never blocks network functionality, so disabling it would never enable a feature like connectivity through a UNC.
C. Incorrect: Enabling LLMNR on WS08A could enable UNC connectivity to another computer running Windows Server 2008 or Windows Vista, but it would not enable UNC connectivity to a computer running Windows XP.
D. Correct: If NetBIOS were disabled, it would block UNC connectivity to a computer running Windows XP.

After the address of a certain client computer is updated, you notice that a local DNS server is resolving the name of the computer incorrectly from cached information. How can you best resolve this problem? CH2 L2
- A.
  
  At the DNS server, type the command dnscmd /clearcache
- B.
  
  Restart the DNS Client service on the client computer.
- C.
  
  At the client computer, type ipconfig /flushdns.
- D.
  
  Restart all DNS client computers.
Correct Answer
A. At the DNS server, type the command dnscmd /clearcache

Explanation
A. Correct: The file Cache.dns, located in the %systemroot%\system32\dns\ folder, contains the list of the root DNS servers that the local DNS server will query if it
cannot itself answer a query. By default, this file contains the list of Internet root servers, but you can replace it with the list of your company root servers.
B. Incorrect: A HOSTS file specifies a list of resolved names that are preloaded into the DNS client cache. It does not specify root servers.
C. Incorrect: The Lmhosts file is used to resolve NetBIOS names. It does not specify DNS root servers.
D. Incorrect: Specifying a forwarder is not the same as specifying root servers. If the connection to a forwarder fails, a DNS server will query its root servers.

You are working on a Windows Server 2008 computer named WS08A. You cannot connect to computers running Windows XP on the local network by specifying them by name in a UNC path such as \\computer1. What can you do to enable your computer to connect to these computers by specifying them in a UNC? CH2 L2
- A.
  
  Enable IPv6 on WS08A.
- B.
  
  Disable IPv6 on WS08A.
- C.
  
  Enable Local Link Multicast Name Resolution (LLMNR) on WS08A.
- D.
  
  Enable NetBIOS on WS08A.
Correct Answer
C. Enable Local Link Multicast Name Resolution (LLMNR) on WS08A.

Explanation
A. Incorrect: This option does not provide a way to resolve Internet names. It also does not provide a way for the New York DNS servers to resolve the names in the Sacramento office.
B. Incorrect: This option does not provide a way for computers in each office to resolve names of the computers in the other office.
C. Correct: This is the only solution that enables the DNS servers to effectively resolve names in the local domain, in the remote domain, and on the Internet.
D. Incorrect: This option does not provide an effective way for computers to resolve Internet names.

- B.
  
  Restart the DNS Client service on the client computer.
- C.
  
  At the client computer, type ipconfig /flushdns.
- D.
  
  Restart all DNS client computers.
Correct Answer
B. Restart the DNS Client service on the client computer.

Explanation
A. Incorrect: Configuring conditional forwarding would allow computers in one domain to resolve names in the other domain. However, the question states that this functionality is already being achieved. Conditional forwarding by itself would not enable clients to connect to resources by using a single-tag name.
B. Correct: If you specify west.cpandl.com on the DNS suffix search list, that suffix will be appended to a DNS query. This option would enable a user to submit a singletag
name query in a UNC path and have the client automatically append the name of the west.cpandl.com domain.
C. Incorrect: This option merely ensures that the client’s own name is registered in DNS. It does not enable a user to connect to resources in the remote domain.
D. Incorrect: By default, the client will append a single-tag name query with the client’s own domain name. If that query fails, the client will append the single-tag name query with the parent domain name. Neither of these options would enable the query for a computer in the remote domain to be resolved properly.

You are working on a Windows Server 2008 computer named WS08A. You cannot connect to computers running Windows XP on the local network by specifying them by name in a UNC path such as \\computer1. What can you do to enable your computer to connect to these computers by specifying them in a UNC? CH2 L3
- A.
  
  Enable IPv6 on WS08A.
- B.
  
  Disable IPv6 on WS08A.
- C.
  
  Enable Local Link Multicast Name Resolution (LLMNR) on WS08A.
- D.
  
  Enable NetBIOS on WS08A.
Correct Answer
D. Enable NetBIOS on WS08A.

Explanation
A. Incorrect: Merely configuring a connection-specific suffix does not enable a computer to register with DNS if all the other settings are left at the default values.
B. Incorrect: Enabling this option registers a connection-specific suffix only if one is configured. If the other settings are left at the default values for a non-DHCP client, this setting would have no effect.
C. Incorrect: This option is already enabled if the DNS client settings are left at the default values.
D. Correct: This answer choice provides the only solution that is not a default value and that, when configured, enables a DNS client to register its static address with a DNS server.

You want to prevent a certain host (A) record from being scavenged. The record belongs to a portable computer named LaptopA that connects to the network only infrequently. LaptopA obtains its address from a DHCP server on the network. Which of the following steps would best enable you to achieve this goal? CH3L1
- A.
  
  Disable scavenging on the zone in which the record has been created.
- B.
  
  Disable scavenging on the server with which the computer registers its record.
- C.
  
  Assign the computer a static address.
- D.
  
  Create a record for LaptopA manually.
Correct Answer
D. Create a record for LaptopA manually.

Explanation
A. Incorrect: If you disable scavenging on the zone, it will affect all records. You want to prevent a single record from being scavenged.
B. Incorrect: If you disable scavenging on the server, it will prevent all records on the server from being scavenged. You want to prevent only a single record from being scavenged.
C. Incorrect: Computers with a static address register their addresses in the same way that the DHCP clients do.
D. Correct: Manually created records are never scavenged. If you need to prevent a certain record from being scavenged in a zone, the best way to achieve that is to
delete the original record and re-create it manually.

You are a network administrator for a company named Fabrikam, Inc. The DNS server for the network is located on a member server named Dns1 in the Fabrikam.com Active Directory domain. Dns1 provides name resolution for the Fabrikam.com domain only. Occasionally, you see DNS records for unauthorized computers in the Fabrikam.comzone. These computers do not have accounts in the Fabrikam.com Active Directory domain. What steps should you take to prevent unauthorized computers from registering host records with the DNS server? (Choose three. Each answer represents part of the solution.) CH3L1
- A.
  
  Re-create the zone on a domain controller.
- B.
  
  Choose the option to store the zone in Active Directory.
- C.
  
  Clear the option to store the zone in Active Directory.
- D.
  
  Configure the zone not to accept dynamic updates.
- E.
  
  Configure the zone to accept secure updates only.
Correct Answer(s)
A. Re-create the zone on a domain controller.
B. Choose the option to store the zone in Active Directory.
E. Configure the zone to accept secure updates only.

Explanation
A. Correct: To prevent computers outside of the Active Directory domain from registering with a DNS server, you need to configure the zone to accept secure dynamic
updates only. You can configure a zone to accept secure dynamic updates only if you store it in Active Directory. You can store a zone in Active Directory only if you create the zone on a domain controller.
B. Correct: To prevent computers outside of the Active Directory domain from registering with a DNS server, you need to configure the zone to accept secure dynamic
updates only. This option is available only if you store the DNS zone in Active Directory, and this last option is available only if you create the zone on a domain controller.
C. Incorrect: If you don’t store the zone in Active Directory, you won’t be able to require secure updates for the zone.
D. Incorrect: If you disable dynamic updates for the zone, no computers will be able to register and you will have to create and update every record manually. This is not the best way to solve this problem because it creates too much administrative overhead.
E. Correct: To prevent computers outside of the Active Directory domain from registering with a DNS server, you need to configure the zone to accept secure dynamic
updates only. This option is available only if you store the DNS zone in Active Directory, and this last option is available only if you create the zone on a domain controller.

You are a network administrator for a large company named Northwind Traders that has many branch offices worldwide. You work at the New York office, which has its own Active Directory domain, ny.us.nwtraders.msft. Recently you have noticed that when users in the New York office want to connect to resources located in the uk.eu.nwtraders.msft domain, name resolution for computernames in the remote domain is very slow. You want to improve name resolution response times for names within uk.eu.nwtraders.msft domain by keeping an updated list of remote name servers authoritative for that domain name. You also want to minimize zone transfer traffic. What should you do?CH3L2
- A.
  
  Create a stub zone of the uk.eu.nwtraders.msft domain on the DNS servers at the New York office.
- B.
  
  Configure conditional forwarding so that queries for names within the uk.eu.nwtraders.msft domain are automatically forwarded to the name servers in that domain.
- C.
  
  Create a secondary zone of the uk.eu.nwtraders.msft domain on the DNS servers at the New York office.
- D.
  
  Perform a delegation of the uk.edu.nwtraders.msft domain on the DNS servers at the New York office.
Correct Answer
A. Create a stub zone of the uk.eu.nwtraders.msft domain on the DNS servers at the New York office.

Explanation
A. Correct: This is the only solution that will improve name resolution response times, keep an updated list of remote name servers, and minimize zone transfer traffic.
B. Incorrect: Conditional forwarding would improve name resolution response times and minimize zone transfer traffic, but it would not allow you to keep an updated list of remote name servers.
C. Incorrect: A secondary zone would improve name resolution response times and allow you to keep an updated list of remote name servers, but it would not minimize
zone transfer traffic because the entire zone would need to be copied periodically from the remote office.
D. Incorrect: You cannot perform a delegation in this case. You can perform a delegation only for a child domain in the DNS namespace. For example, a child domain of the ny.us.nwtraders.msft domain might be uptown.ny.us.nwtraders.msft.

You have recently migrated a DNS zone named Contoso.com to a domain controller running Windows Server 2008. You have selected the option to store the zone in Active Directory, but you find that the zone does not appear on a domain controller named DC2000 that is running Windows 2000 Server in the same domain. DC2000 is already configured with the DNS server component. You want the zone to appear on all domain controllers in the Contoso.com domain. What should you do? CH3L2
- A.
  
  Choose the option to store the zone in all DNS servers in the forest.
- B.
  
  Choose the option to store the zone in all DNS servers in the domain.
- C.
  
  Choose the option to store the zone in all domain controllers in the domain.
- D.
  
  Create a new directory partition, and then choose the option to store the zone in the new partition.
Correct Answer
C. Choose the option to store the zone in all domain controllers in the domain.

Explanation
A. Incorrect: When you choose this option, computers running Windows 2000 Server cannot see the ForestDnsZones partition in which zone data is stored.
B. Incorrect: When you choose this option, computers running Windows 2000 Server cannot see the DomainDnsZones partition in which zone data is stored.
C. Correct: When you choose this option, zone data is stored in the domain partition, which is visible to computers running Windows 2000 Server.
D. Incorrect: Computers running Windows 2000 Server would not be able to see any new application directory partitions that you create, so creating one and choosing
the associated option would not resolve the problem.

After you deploy a DHCP server for the 192.168.1.0/24 subnet, you find that none of the DHCP clients can communicate beyond the local subnet when they specify the IP address of a computer on the company network. Statically assigned computers can successfully communicate beyond the local subnet. How can you configure the DHCP server to enable DHCP clients to communicate beyond the local subnet? CH4L1
- A.
  
  Configure the 003 Router option.
- B.
  
  Configure the 006 DNS Servers option.
- C.
  
  Configure the 015 Domain Name option.
- D.
  
  Configure the 044 WINS/NBNS Servers option.
Correct Answer
A. Configure the 003 Router option.

Explanation
A. Correct: If computers cannot communicate beyond the local subnet even when you specify an IP address, the problem is most likely that the computers do not have a default gateway specified. To assign a default gateway address to DHCP clients, configure the 003 Router option.
B. Incorrect: If the DHCP clients needed to have a DNS server assigned to them, they would be able to connect to computers when specified by address but not by name.
C. Incorrect: The 015 Domain Name option provides DHCP clients with a connection- specific DNS suffix assigned to them. If clients needed such a suffix, the problem
reported would be that clients could not connect to servers when users specified a single-label computer name such as “Server1” (instead of a fully qualified domain name [FQDN] such as “Server1.contoso.com”).
D. Incorrect: The 044 WINS/NBNS Server option configures DHCP clients with the address of a WINS server. A WINS server would not enable you to connect to computers
on remote subnets when you specify those computers by address.

You want to deploy a DHCP server on a computer named Dhcp1.nwtraders.msft. To this server you have configured a static address of 10.10.0.5/24 and assigned a DNS server address of 10.10.1.1. On Dhcp1 you configure a scope within the range 10.10.1.0/24. You then activate the scope and authorize the server, but the server does not successfully lease any addresses to computers on the local subnet. When you verify the addresses of the clients on the subnet, you find that they are all assigned addresses in the169.254.0.0/16 range. You want the DHCP server to lease addresses to client computers on the local subnet only. Which of the following actions will most likely fix the problem? CH4L1
- A.
  
  Configure the clients as DHCP clients.
- B.
  
  Enable the DHCP client service on Dhcp1.
- C.
  
  Change the address of Dhcp1 and redeploy the DHCP server.
- D.
  
  Run the command Ipconfig /registerdns on Dhcp1.
Correct Answer
C. Change the address of Dhcp1 and redeploy the DHCP server.

Explanation
A. Incorrect: We know that clients are already configured as DHCP clients because they have received addresses in the APIPA range of 169.254.0.0/16.
B. Incorrect: Dhcp1 does not need to be running the DHCP client service because itis not acting as a DHCP client.
C. Correct: If you want the DHCP server to assign addresses to computers on the local subnet, the server needs to be assigned an address that is also located on the same subnet. With its current configuration, the server is configured with an address in the 10.10.0.0/24 subnet but is attempting to lease addresses in the 10.10.1.0/24 range. To fix this problem, you can either change the address of the DHCP server or change the address range of the scope.
D. Incorrect: This command would enable other computers to connect to Dhcp1 if a user specified Dhcp1 by name. However, the ability to connect to a DHCP server by
specifying its name is not a requirement for DHCP to function correctly. DHCP exchanges do not rely on computer names.

You are deploying a DHCP server on your network to supply addresses in the 192.168.1.0/24 range. You have 200 DHCP client computers on the local subnet. The subnet includes a DNS server on the network with a statically assigned address of 192.168.1.100. How can you create a scope on the DHCP server that does not conflict with the existing DNS server address? CH4L2
- A.
  
  Use the 006 DNS Servers option to assign to clients the address of the DNS server.
- B.
  
  Create a reservation that assigns the address 192.168.1.100 to the DNS server.
- C.
  
  Configure two address ranges in the DHCP scope that avoids the address 192.168.1.100.
- D.
  
  Create an exclusion for the address 192.168.1.100.
Correct Answer
D. Create an exclusion for the address 192.168.1.100.

Explanation
A. Incorrect: Configuring a scope option that assigns clients the DNS server address does nothing to prevent the potential conflict of the scope leasing out the same
address owned by the DNS server.
B. Incorrect: It is not recommended to assign reservations to infrastructure servers such as DNS servers. DNS servers should be assigned static addresses.
C. Incorrect: You can configure only one contiguous address range per scope.
D. Correct: Creating an exclusion for the DNS server address is the simplest way to solve the problem. When you configure the exclusion, the DHCP server will not lease the address and the DNS server preserves its static conguration.

Currently, client computers on the 192.168.1.0/24 subnet are configured with the default gateway 192.168.1.1. You connect a second router to both the 192.168.1.0/24subnet and the 192.168.2.0/24 subnet. You would like clients on the 192.168.1.0/24 subnet to connect to the 192.168.2.0/24 subnet using the new router, which has the IP address 192.168.1.2. What command should you run? CH5L1
- A.
  
  Route add 192.168.2.0 MASK 255.255.255.0 192.168.1.1
- B.
  
  Route add 192.168.2.0 MASK 255.255.255.0 192.168.1.2
- C.
  
  Route add 192.168.1.2 MASK 255.255.255.0 192.168.2.0
- D.
  
  Route add 192.168.1.1 MASK 255.255.255.0 192.168.2.0
Correct Answer
B. Route add 192.168.2.0 MASK 255.255.255.0 192.168.1.2

Explanation
A. Incorrect: This answer has the incorrect router. The router with the IP address 192.168.1.1 is currently the default gateway, so all traffic will be sent to that router

You are experiencing intermittent connectivity problems accessing an internal Web site on a remote network. You would like to view a list of routers that packets travel throughbetween the client and the server. Which tools can you use? (Choose all that apply.) CH5L1
- A.
  
  PathPing
- B.
  
  Ping
- C.
  
  Ipconfig
- D.
  
  TraceRt
Correct Answer(s)
A. PathPing
D. TraceRt

Explanation
A. Correct: PathPing uses ICMP to detect routers between your computer and a specified destination. Then PathPing computes the latency to each router in the path.
B. Incorrect: Ping tests connectivity to a single destination. You cannot easily use Ping to determine the routers in a path.
C. Incorrect: Although you can use Ipconfig to determine the default gateway, you cannot use it to determine all routers in a path.
D. Correct: TraceRt provides very similar functionality to PathPing, using ICMP to contact every router between your computer and a specified destination. The key different between TraceRt and PathPing is that PathPing computes accurate performance statistics over a period of time, while TraceRt sends only three packets to each router in the path and displays the latency for each of those three packets.

6L1You configure a computer running Windows Server 2008 with two network interfaces. Each of the interfaces is connected to different subnets. One of those subnets has four other routers connected to it, and each router provides access to different subnets. You would like the computer running Windows Server 2008 to automatically identify therouters and determine which remote subnets are available using each router. What should you do? CH5L1
- A.
  
  Enable NAT on the interface.
- B.
  
  Enable OSPF on the interface.
- C.
  
  Enable RIP on the interface.
- D.
  
  Add a static route to the interface.
Correct Answer
C. Enable RIP on the interface.

Explanation
A. Incorrect: Network Address Translation (NAT) allows clients with private IP addresses to connect to computers on the public Internet. NAT does not automatically configure routing.
B. Incorrect: Although OSPF is a routing protocol and would meet the requirements of this scenario, Windows Server 2008 does not support OSPF. Earlier versions of Windows do support OSPF.
C. Correct: RIP is a routing protocol. Routing protocols allow routers to communicate a list of subnets that each router provides access to. If you enable RIP on a computer running Windows Server 2008, it can automatically identify neighboring routers and forward traffic to remote subnets.
D. Incorrect: Although you could use static routes to reach remote subnets, the question requires you to configure Windows Server 2008 to automatically identify the
remote networks.

  Use IPSec with Encapsulating Security Payload (ESP).
- C.
  
  Use IPSec with both AH and ESP.
- D.
  
  Use IPSec in tunnel mode.
Correct Answer
B. Use IPSec with Encapsulating Security Payload (ESP).

Explanation
A. Incorrect: AH provides data authentication but not data encryption.
B. Correct: ESP is the protocol that provides encryption for IPsec.
C. Incorrect: Using IPsec with both AH and ESP is not the best answer because only ESP is needed to encrypt data. Using AH with ESP increases the processing overhead
unnecessarily.

You want to enforce IPSec communications between the Nwtraders.com domain and the Contoso.com domain. Both domains belong to the same Active Directory forest. Whichauthentication method should you choose for IPSec? CH6L1
- A.
  
  Kerberos
- B.
  
  Certificates
- C.
  
  Preshared key
- D.
  
  NTLM
Correct Answer
A. Kerberos

Explanation
A. Correct: If both domains are in the same Active Directory forest, you can use the Kerberos protocol built into Active Directory to provide authentication for IPsec
communication.
B. Incorrect: You do not need to configure certificates for authentication. Active Directory already provides the Kerberos protocol that you can use with IPsec.
C. Incorrect: You do not need to configure a preshared key as the authentication method. The Kerberos protocol is already available, and it is more secure than a preshared key.
D. Incorrect: NTLM is a backup authentication method for Active Directory, but it is not a valid authentication method for IPsec

Which of the following scenarios are not likely to work with NAT without additional configuration? CH7L1
- A.
  
  Clients on the Internet accessing a Web server on the intranet using HTTP
- B.
  
  Clients on the intranet downloading e-mail from an Exchange server on the Internet
- C.
  
  Clients on the intranet streaming video using a TCP connection from a server on the Internet
- D.
  
  Clients on the intranet accessing a Web server on the Internet using HTTPS
Correct Answer
A. Clients on the Internet accessing a Web server on the intranet using HTTP

Explanation
A. Correct: By default, NAT does not allow connections from the Internet to the intranet. You can support them, however, by configuring port forwarding on the NAT
server. With port forwarding, the NAT device accepts the TCP connection and forwards it to a specific server on the intranet.
B. Incorrect: NAT allows clients to establish TCP connections to servers on the Internet.
C. Incorrect: Streaming video often uses User Datagram Protocol (UDP), which often fails when a NAT device is in use. However, streaming video connections that use TCP should always work. For that reason, most streaming media protocols support both UDP (for performance) and TCP (for compatibility with NAT).
D. Incorrect: HTTPs functions exactly like any other TCP connection. Therefore, NAT clients do not have any problem establishing an HTTPS connection to a server on the Internet.

  The DNS server address provided by your ISP
- C.
  
  192.168.0.1
- D.
  
  192.168.0.0
Correct Answer
C. 192.168.0.1

Explanation
A. Incorrect: The Internet network adapter should have the IP address that was assigned by your ISP, not the internal network adapter.
B. Incorrect: You should configure the ICS server to send queries to the DNS server and client computers to send DNS queries to the ICS server. However, you should not configure the internal network adapter with the DNS server’s IP address.
C. Correct: ICS always assigns the IP address 192.168.0.1 to the internal network adapter.
D. Incorrect: 192.168.0.0/24 is the internal network that ICS assigns to clients. 192.168.0.0 is not a valid IP address, however.

You are a systems administrator at an enterprise help desk. A user calls to complain that she is unable to connect to the wireless network. After discussing her problem, you discover that the wireless access point is rejecting her credentials. You examine the wireless access point configuration and determine that it is submitting authentication requests to a RADIUS service running on a Windows Server 2008 computer. How can you determine the exact cause of the authentication failures?CH7L2
- A.
  
  Examine the Security event log on the wireless client.
- B.
  
  Examine the System event log on the wireless client.
- C.
  
  Examine the Security event log on the computer running Windows Server 2008.
- D.
  
  Examine the System event log on the computer running Windows Server 2008.
Correct Answer
C. Examine the Security event log on the computer running Windows Server 2008.

Explanation
A. Incorrect: The wireless client cannot log detailed information about authentication failures because RADIUS does not provide detailed information about why credentials were rejected. Instead, you should examine the Security event log on the RADIUS server.
B. Incorrect: Same as answer A.
C. Correct: The Windows Server 2008 RADIUS service adds events to the local Security event log. These events have information useful for identifying the cause of the
problem, such as the user name submitted.
D. Incorrect: The Windows Server 2008 RADIUS service adds events to the local Security event log, not to the System event log.

To improve productivity for employees during meetings, your organization has decided to provide authentication and encrypted wireless network access throughout your facilities. The organization is not willing to sacrifice security, however, and requires the most secure authentication mechanisms available. You have recently upgraded all client computers to either Windows XP (with the latest service pack) or Windows Vista. Which wireless security standard should you use?CH7L2
- A.
  
  128-bit WEP
- B.
  
  WPA-PSK
- C.
  
  64-bit WEP
- D.
  
  WPA-EAP
Correct Answer
D. WPA-EAP

Explanation
A. Incorrect: 128-bit WEP provides much better security than 64-bit WEP. However, 128-bit WEP is still considered extremely unsecure because it uses static keys and can be cracked in a relatively short time.
B. Incorrect: WPA-PSK uses static keys, making it vulnerable to brute force attacks. WPA-PSK should be used only for testing.
C. Incorrect: 64-bit WEP is the original wireless security standard, and it is now considered outdated. 64-bit WEP uses small, static keys and contains several cryptographic
weaknesses that allow it to be cracked in a short time.
D. Correct: WPA-EAP (and WPA2-EAP) provide the highest level of security by authenticating users to a central RADIUS server, such as a server running Windows Server 2008. As of the time of this writing, breaking WPA-EAP security using brute force techniques would be much more difficult than any other wireless security standard.

You are a systems engineer for a paper sales company. Frequently, your sales staff travels overnight and needs to connect to resources on your protected intranet. After discussions with some of the sales staff, you discover that they frequently use their mobile computers to connect to the Internet using wireless networks. At other times, hotels offer Ethernet connections with Internet access. Frequently, however, they have access only to a phone line that they can use to establish a dial-up connection. At any given time, 100 salespeople might need to connect, and at most 30 would need dial-up connections. Your organization is near the end of its fiscal year, and capital budget is tight. Therefore, you need to minimize up-front costs. What is the best way to configure remote access for the sales staff while using existing Active Directory user credentials?

- D.
  
  Establish an agreement with an ISP to provide dial-up access to your users. Then, configure a Windows Server 2008 computer as a RADIUS server. Have the ISP configure its modem bank to submit authentication requests to the RADIUS server.
Correct Answer(s)
A. Connect a Windows Server 2008 computer to both the public Internet and your intranet. Then, configure it to accept incoming VPN connections.
D. Establish an agreement with an ISP to provide dial-up access to your users. Then, configure a Windows Server 2008 computer as a RADIUS server. Have the ISP configure its modem bank to submit authentication requests to the RADIUS server.

Explanation
A. Correct: A VPN server allows clients on the public Internet to connect to your intranet while providing authentication and encryption.
B. Incorrect: Clients never submit requests directly to a RADIUS server. Instead, a wireless access point, VPN server, or other access provider submits authentication
requests to the RADIUS server on the client’s behalf. Additionally, without a VPN connection, client computers would not have access to the internal network.
C. Incorrect: Configuring your own modem bank and telephone circuits would provide the required connectivity. However, the capital expense would be significant. A more cost-effective alternative is to outsource the dial-up access to an ISP.
D. Correct: ISPs can provide dial-up access with integrated VPN connections to clients and authenticate to your internal RADIUS server. With Windows Server 2008, the RADIUS server can, in turn, authenticate to an Active Directory domain controller.

Correct Answer(s)
A. In the General tab, click Allow Only Secure Connections.
C. In the Users And Computers tab, select Only Allow Connections From These Users. Then, add the Domain Users group.

Explanation
A. Correct: Selecting Allow Only Secure Connections requires IPsec, which you must use to require domain authentication at the firewall level.
B. Incorrect: Specifying a profile for the firewall rule simply means the rule won’t apply if the server isn’t connected to the domain network. You can’t use profiles to require client connection authentication.
C. Correct: After requiring IPsec on the General tab, you can use this tab to limit connections only to users who are members of specific groups.
D. Incorrect: Configuring scope can be a very powerful tool for limiting connections from users. Although it might be advisable to also limit scope to connections from client computers on your internal network, that doesn’t necessarily require users to be a member of your domain.

- D.
  
  Deploy a WSUS server to each office. Configure the WSUS servers at the remote offices to be replicas of the WSUS server at the headquarters.
Correct Answer
D. Deploy a WSUS server to each office. Configure the WSUS servers at the remote offices to be replicas of the WSUS server at the headquarters.

Explanation
A. Incorrect: Because you have a centralized IT department, having local IT departments manage the WSUS servers would be inefficient. Instead, you should configure the remote offices as replicas of the WSUS servr at the headquarters, allowing you to manage all updates using a single WSUS server.
B. Incorrect: Although this architecture would work, it would be extremely wasteful of Internet bandwidth. The bandwidth required for 1200 client computers to each download a service pack from the Internet would be so extreme that for many computers the updates might never succeed.
C. Incorrect: Like answer B, this architecture would work. However, the WAN links would likely be saturated with update traffic as every computer at each remote office transfers large updates. To resolve this, place WSUS servers at each office.
D. Correct: To make best use of WAN and Internet bandwidth, configure a WSUS server at each office and have each computer download updates from your central WSUS server.

You create a folder named Marketing on a computer named FileServer and configure NTFS permissions to grant the Domain Users group Read permission and the Marketing group Modify permission. You share the folder and grant the Everyone group Reader permission. Mary, a user account who is a member of both the Marketing group and the Domain Users group, logs on locally to the FileServer computer to access the Marketing folder. What effective permissions will Mary have? CH11L1
- A.
  
  No access
- B.
  
  Read
- C.
  
  Write
- D.
  
  Full Control
Correct Answer
C. Write

Explanation
A. Incorrect: Users have No Access permission if no access control entry applies to them or if they explicitly have a Deny permission assigned. In this case, Mary has Write access because she has the Modify NTFS permission assigned.
B. Incorrect: Share permissions apply only when users access a folder across the network. Because Mary is accessing the folder from the local computer, only NTFS
permissions apply. The Marketing group is granted Modify NTFS permissions, which allows Mary to write to the folder (in addition to being able to read the contents of the folder).
C. Correct: Through Mary’s membership in the Marketing group, Mary has the Modify NTFS permission. Because Mary is not accessing the files using the share, share
permissions do not affect Mary’s effective permissions. Therefore, Mary can write to the folder.
D. Incorrect: Full Control permissions allow users to change permissions. Having this level of access would require Mary to have Full Control NTFS permissions.

  Right-click the file, and then choose Properties. In the General tab, click Advanced. Clear the Encrypt Contents To Secure Data check box.
- D.
  
  Do nothing.
Correct Answer
D. Do nothing.

Explanation
A. Incorrect: This procedure would add NTFS permissions for the user. However, the user already has the necessary NTFS permissions.
B. Incorrect: This is the correct procedure for allowing local users to share EFSencrypted files. However, it is not necessary when users connect across the network.
C. Incorrect: Although removing encryption would allow the user to access the file, it would also reduce security.
D. Correct: EFS affects only users who access files locally. Therefore, because the user is connecting across the network, you do not need to make any changes.
