Questions and Answers
  • 1. 

    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-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.

    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. 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.

    Rate this question:

  • 8. 

    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 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.

    Rate this question:

  • 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?

    • A.

      Half duplex

    • B.

      Full duplex

    • C.

      Super duplex mode

    • D.

      Single duplex

    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.

    Rate this question:

  • 10. 

    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 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.

    Rate this question:

  • 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?

    • A.

      Router

    • B.

      Bridges

    • C.

      Repeaters

    • D.

      VLAN technology

    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.

  • 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.)

    • A.

      Use the UNC path of the resource you need access to

    • B.

      Contact the network administer for help

    • C.

      Use the map network drive tool

    • D.

      Just walk over to the server and do what you need

    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.

    Rate this question:

  • 16. 

    Which of the following programs enables a user to browse the Internet? (Choose two.)

    • A.

      Internet Explorer

      Windows Explorer

    • D.

      The command prompt

    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.

    Rate this question:

  • 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?

    • A.

      Run ipconfig /release

    • B.

      Run ipconfig /flushdns

    • C.

      Ping the IP address of the client's computer

    • D.

      Walk her through how to ping the server

    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.

    Rate this question:

  • 18. 

    A user is unable to access the network. Which of the following could cause this to happen? (Choose all that apply.)

    • A.

      Damage to cables

    • B.

      A faulty network card

    • C.

      The boot files are corrupt

    • D.

      Connecting a high speed NIC to low speed port

    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.
