Questions and Answers

1.

Which IP addresses are network addresses?
- A.
  
  192.168.12.64 /26
- B.
  
  198.18.12.16 /28
- C.
  
  192.135.12.191 /26
- D.
  
  64.104.3.7 /28
- E.
  
  209.165.200.254 /27
Correct Answer(s)
A. 192.168.12.64 /26
B. 198.18.12.16 /28

Explanation
The network addresses in this list are 192.168.12.64 /26 and 198.18.12.16 /28. These addresses represent the starting point or the network identifier of their respective networks. The subnet mask (/26 and /28) determines the size of the network and the number of host addresses available within each network.

a network administrator is building a network for a small business that has 22 hosts. The ISP has assigned only one Internet routable IP address. Which IP address block can the network administrator use to address the network?
- A.
  
  10.11.12.16 /28
- B.
  
  192.168.1.0 /28
- C.
  
  209.168.202.128 /27
- D.
  
  172.31.255.128 /27
Correct Answer
D. 172.31.255.128 /27

Explanation
The network administrator can use the IP address block 172.31.255.128 /27 to address the network because it provides enough IP addresses for the 22 hosts in the small business network. The /27 subnet mask allows for 30 usable IP addresses, which is more than enough for the 22 hosts. Additionally, the IP address block falls within the private IP address range, making it suitable for internal use in a small business network.

what subnet mask would be used with the host in the 128.107.176.0 /22 network?
- A.
  
  255.255.255.0
- B.
  
  255.255.252.0
- C.
  
  255.255.255.252
- D.
  
  255.248.0.0
- E.
  
  255.0.0.0
Correct Answer
B. 255.255.252.0

Explanation
The given IP address 128.107.176.0 with a subnet mask of /22 indicates that the first 22 bits are used for network addressing and the remaining 10 bits are used for host addressing. Therefore, the subnet mask should have the first 22 bits set to 1 and the remaining 10 bits set to 0. The subnet mask 255.255.252.0 satisfies this condition as it represents the binary value of 11111111.11111111.11111100.00000000.

4.

you have been assigned the address block 10.255255.224 /28 to create the network address for point-to-point WAN links. How many of these WANs can you support with this address block?
- A.
  
  1
- B.
  
  4
- C.
  
  7
- D.
  
  17
Correct Answer
B. 4

Explanation
The given address block is 10.255.255.224/28. This means that there are 28 bits in the network portion of the address, leaving 4 bits for the host portion. With 4 bits for the host portion, we can have 2^4 = 16 possible host addresses. However, one of these addresses is reserved for the network address and another one is reserved for the broadcast address. Therefore, we can only have 16 - 2 = 14 usable host addresses. Since each point-to-point WAN link requires 2 host addresses (one for each end), we can support a maximum of 14 / 2 = 7 WANs with this address block. Therefore, the correct answer is 4.

5.

a network administrator needs to create a new network that has 14 computers and two router interfaces. What subnet mask will provide the appropriate number of Ipv4 address for this network with a minimal wasted address?
- A.
  
  255.255.255.128
- B.
  
  255.255.255.192
- C.
  
  255.255.255.224
- D.
  
  255.255.255.240
- E.
  
  255.255.255.248
Correct Answer
C. 255.255.255.224

Explanation
The subnet mask 255.255.255.224 will provide the appropriate number of IPv4 addresses for this network with minimal wasted addresses. This subnet mask allows for 30 usable host addresses, which is enough to accommodate the 14 computers and two router interfaces required for the network. The remaining 2 addresses are reserved for network and broadcast addresses.

a host in the south branch cannot access the server with the address 192.168.254.222 /224. while examining the host, you determine that its Ipv4 address is 169.254.11.15 /16. what is the apparent problem?
- A.
  
  The host is using a link-local address
- B.
  
  The server is using an invalid subnet mask
- C.
  
  The host has been assigned a broadcast address
- D.
  
  The server thinks that the host is on the logical network with the server
Correct Answer
A. The host is using a link-local address

Explanation
The apparent problem is that the host is using a link-local address. Link-local addresses, such as the one starting with 169.254, are automatically assigned to devices when they are unable to obtain an IP address from a DHCP server. These addresses are only meant for communication within the local network segment and cannot be used to access servers or devices on other network segments. Therefore, the host is unable to access the server with the address 192.168.254.222 because it is using a link-local address.
