The Windows operating system uses two major types of networks. Which of the following are the two?
Correct Answer(s)
A. Client/server
C. Peer-to-peer
Explanation
The Windows operating system uses two types of networks. One is a client/server network, meaning that client computers will need to contact a domain controller to work. A peer-to-peer network is used in smaller networks where the expense is a factor, no centralized administration is necessary, or if the organization doesn’t have the resources to support a client/server network.
2.
One reason for implementing a network is to share the Internet. Which of the following methods can connect a network to the Internet? (Choose all that apply.)
Correct Answer(s)
A. Dial-up modem
B. ISDN modem
C. DSL modem
D. Cable modem
Explanation
Although the older dial-up modems are going by the wayside, they are still used. The newer technologies such as an ISDN, cable, and DSL more commonly connect today’s networks to the Internet.
3.
You are a technician for your company. You have been asked to determine which protocols are in use. You discover that the company is using TCP/IPv4. Which of the following network protocols might you also find on the network? (Choose all that apply.)
Correct Answer(s)
A. TCP/IPv6
C. NetBEUI
Explanation
Although most current networks use TCP/IPv4, you can also find the TCP/IPv6 and in some situations you might even find the older NetBEUI protocol.
4.
Which of the following technologies are part of the TCP/IP suite? (Choose all that apply.)
Correct Answer(s)
A. HTTP/HTTPS
B. SSL
C. TLS
Explanation
The TCP/IP protocol suite includes many protocols including the Hypertext Transfer Protocol (HTTP), HTTP Secure (HTTPS), Secure Sockets Layer (SSL), and its successor Transport Layer Security (TLS). Ethernet is a network architecture commonly used, upon which TCP/IP runs.
5.
You have been asked to recommend a network topology to use in a new network. Which of the following are valid network topologies?
Correct Answer
E. All of these options are correct
Explanation
Bus, star, ring, and mesh topologies are used in the field today. You can use these techniques to supply network connectivity to your client computers.
6.
The company you work for is using the oldest and most commonly used network today, Ethernet. Which of the following is another name for Ethernet?
Correct Answer
C. IEEE 802.3
Explanation
The oldest network in common use today is Ethernet, also known as IEEE-802.3. IEEE 1394 refers to the PC version of FireWire cable. 802.11b and 802.11g are wireless networking technologies.
7.
You have been asked by your company to create and install a network. You have decided that you are using Category 5e. Which of the following is the most common type of cable used by Cat5e? (Choose all that apply.)
Correct Answer
C. UTP
Explanation
UTP cable comes in various grades, of which Category 5e is the most common of the standard cabling grades. Category 5e cabling is suitable for use with both standard 10BaseT and Fast Ethernet networking, and can also be used for Gigabit Ethernet networks if it passes compliance testing. STP is a form of cabling also available in Cat5e, but is used only when shielding from EMI/RFI is necessary, as it is more expensive, bulkier, and harder to work with than UTP.
8.
Which of the following devices would you need if a client asks you to connect his computer to a network? (Choose two.)
Correct Answer(s)
A. A network interface card
B. A wireless card
Explanation
Although many recent computers include a 10/100 or 10/100/1000 Ethernet port or a wireless Ethernet adapter, you might need to install a network interface card (NIC) into a computer you want to add to a network. For desktops, the card would be installed into a PCIe x1 or a PCI slot; for laptops, the card would be installed into an ExpressCard or CardBus slot. A USB network adapter could be used by both types of computers.
9.
You are installing a network interface card. You have been instructed to configure the network card to send and receive data at the same time. Which of the following settings will you need to configure the network card to complete what has been asked of you?
Correct Answer
B. Full duplex
Explanation
If the hardware in use on an Ethernet, Fast Ethernet, or Gigabit Ethernet network permits, you can configure the network to run in full-duplex mode. Full-duplex mode enables the adapter to send and receive data at the same time, which doubles network speed over the default half-duplex mode.
10.
You have been asked by your company to upgrade all hubs to switches. How would this upgrade change the existing network?
Correct Answer
C. A switch creates a dedicated full speed connection
Explanation
A switch resembles a hub but creates a dedicated full-speed connection between the two computers that are communicating with each other. By doing this it will upgrade the speed of the existing network.
11.
You have been asked by a company to analyze their network. You find several hubs and switches within the network. Which of the following additional devices might you find in this network?
Correct Answer(s)
A. Router
B. Bridges
C. Repeaters
Explanation
Hubs or switches are the only connectivity equipment needed for a workgroup LAN. However, if the network needs to span longer distances than those supported by the network cabling in use or needs to connect to another network, additional connectivity equipment is needed. A repeater is used to carry the signals even farther than normal. You can also use a bridge to connect two networks together. A router can be used to connect two or more networks.
12.
You have been contacted by a client that is having problems connecting to the Internet. Where would be a good place to start the troubleshooting process?
Correct Answer
B. Run the Ping command-line utilty
Explanation
Ping is a command-line utility used to check Internet connectivity. Ping is already included in Windows.
13.
You have been contacted by a client that is unable to access network printers and other shared resources. Which of the following should you verify is installed and enabled?
Correct Answer
C. File and print sharing
Explanation
On a Windows operating system, to be able to share printers and resources with other users, you must make sure that the file and print services are installed and enabled in the Properties window of a network connection.
14.
What is the name of the service that must be installed on a Windows computer to connect to a network?
Correct Answer
A. WINS
Explanation
WINS is the Windows Internet Naming Service. WINS is already installed as part of Windows’ TCP/IP support.
15.
You need to connect to a server to use shared resources. Which of the following are ways to connect to the server? (Choose two.)
Correct Answer(s)
A. Use the UNC path of the resource you need access to
C. Use the map network drive tool
Explanation
The Universal Naming Convention (UNC) is designed to enable users to access network resources, such as folders or printers, without mapping drive letters to network drives or specifying the type of device that stores the file or hosts the printer. If you are using a Windows operating system, you can also use the map network drive tool and provide the UNC path.
16.
Which of the following programs enables a user to browse the Internet? (Choose two.)
Correct Answer(s)
A. Internet Explorer
B. Firefox
Explanation
A web browser, such as Microsoft Internet Explorer or Mozilla Firefox, is the main interface through which you navigate the Internet. Internet Explorer is a standard component of Windows. Updates and newer versions can be downloaded manually from the Microsoft website or via Windows Update. Other browsers can be downloaded in compressed form and installed manually.
17.
A user with your company is having connectivity problems. You need to diagnose the problem as soon as possible. You call the client and walk her through finding the IP address. What should you do next?
Correct Answer
C. Ping the IP address of the client's computer
Explanation
After you have discerned the IP address of the client’s computer, ping that IP address to see if it is alive. If you get replies, then the client computer has network connectivity. If your ping times out, then you will need to troubleshoot the issue further.
18.
A user is unable to access the network. Which of the following could cause this to happen? (Choose all that apply.)
Correct Answer(s)
A. Damage to cables
B. A faulty network card
Explanation
If a user reports that he or she cannot connect to the network, check cables, connectors, and other network hardware. A disconnected cable is a common culprit. A faulty connector or network card could also be the cause. Replace any damaged cables and connectors.
