The Windows operating system uses two major types of networks. Which of the following are the two?
- A.
Client/server
- B.
Node server
- C.
Peer-to-peer
- D.
IP network model
Correct Answer(s)
A. Client/server
C. Peer-to-peerExplanation
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.Rate this question:

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.)
- A.
STP
- B.
Coaxial
- C.
UTP
- D.
Thin-net
Correct Answer
C. UTPExplanation
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.Rate this question:

Which of the following devices would you need if a client asks you to connect his computer to a network? (Choose two.)
- A.
A network interface card
- B.
A wireless card
- C.
An AGP adapter card
- D.
A BNC connector
Correct Answer(s)
A. A network interface card
B. A wireless cardExplanation
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.Rate this question:

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?
- A.
Half duplex
- B.
Full duplex
- C.
Super duplex mode
- D.
Single duplex
Correct Answer
B. Full duplexExplanation
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.Rate this question:

You have been asked by your company to upgrade all hubs to switches. How would this upgrade change the existing network?
- A.
The network will be slower
- B.
There is no difference in speeds
- C.
A switch creates a dedicated full speed connection
- D.
You do not need to have NIC cards
Correct Answer
C. A switch creates a dedicated full speed connectionExplanation
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.Rate this question:

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?
- A.
Router
- B.
Bridges
- C.
Repeaters
- D.
VLAN technology
Correct Answer(s)
A. Router
B. Bridges
C. RepeatersExplanation
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.Rate this question:
