1. Which IEEE standard is used for PoE?

   • 802.3af
   • 802.11af
   • 802.1q
   • 802.15
     

     Answers Explanation & Hints: 802.3af is an IEEE standard for PoE. Other PoE standards are 802.3at and 802.3bt. 802.11af is a wireless LAN standard. 802.1q is a standard specifying the tagging of VLAN frames across a trunk link. 802.15 is the IEEE standard for personal area networks that includes Bluetooth.

2. A customer is considering a multipurpose device to create a home network. Which three devices are usually integrated into a multipurpose network device? (Choose three.)

   • web server
   • switch
   • router
   • email server
   • wireless access point
   • print server
     

     Answers Explanation & Hints: A web server could be software installed on a computer. An email server is commonly provided by a provider like Google or Yahoo or built and provided in a corporate environment. Print servers are commonly found in a business, not home, environment.

3. Which two devices are commonly powered by PoE? (Choose two.)

   • access point
   • core switch
   • IP phone
   • modular switch
   • router
     

     Answers Explanation & Hints: Compact switches, APs, and IP phones can be powered by a PoE-enabled switch. Routers and modular switches require a large amount of energy and cannot be powered through an Ethernet cable.

4. Which two types of signal interference are reduced more by STP than by UTP? (Choose two.)

   • RFI
   • white noise
   • MDF
   • dispersion
   • EMI
     

     Answers Explanation & Hints: RFI, EMI, and crosstalk cause interference to the electrical signals that are transmitted through copper cables. Both UTP and STP use twisted pairs of wires that help protect against crosstalk. However, STP provides greater protection against RFI and EMI than UTP provides.

5. When would a printer be considered a network host?

   • when it is connected to a switch
   • when it is connected to a workstation
   • when it is connected to a laptop
   • when it is connected to a PC
     

     Answers Explanation & Hints: When a printer is connected directly to a networking device, such as a hub, switch, or router, it is considered to be a network host.

6. Which technology is most often used to connect devices to a PAN?

   • coaxial cabling
   • Bluetooth
   • fiber optic cabling
   • IEEE 802.11n wireless
     

     Answers Explanation & Hints: A personal-area network (PAN) connects wireless devices that are within close proximity of an individual person. Bluetooth network technology commonly provides the connectivity.

7. A network specialist has been hired to install a network in a company that assembles airplane engines. Because of the nature of the business, the area is highly affected by electromagnetic interference. Which type of network media should be recommended so that the data communication will not be affected by EMI?

   • STP
   • coaxial
   • fiber optic
   • UTP
     

     Answers Explanation & Hints: Optical fiber uses light to transmit signals. Therefore, fiber-optic cable is not affected by EMI or RFI.

8. How many devices can a Bluetooth device connect to simultaneously?

   • 127
   • 7
   • 10
   • 24
   • 5

9. Which network device makes forwarding decisions based on the destination MAC address that is contained in the frame?

   • repeater
   • hub
   • switch
   • router
     

     Answers Explanation & Hints: Switches are the central connection point for a LAN and they maintain a MAC address table. The MAC address table has a port number associated with a MAC address for each particular device. The switch inspects a frame to look at the destination MAC address. The switch then looks in its MAC address table and if that MAC address is found, the switch forwards the data to the port that is associated with that particular MAC address.

10. What is a common function of a proxy server?

    • to store frequently accessed web pages on the internal network
    • to control who is permitted to access the internal network
    • to detect malicious signatures by monitoring traffic that is entering the internal network
    • to provide access to a shared pool of configurable computing resources
      

      Answers Explanation & Hints: A proxy server is often responsible for caching web pages frequently accessed by internal users. If another internal user requests any of the stored pages, the proxy server can quickly provide the stored web pages to the internal user instead of sending the request over the Internet to the original web server.

11. What is a characteristic of a WAN?

    • It connects multiple networks that are geographically separated.
    • It spans across a campus or city to enable sharing of regional resources.
    • It is typically owned and managed by a single home or business.
    • It requires a wireless access point to connect users to the network.
      

      Answers Explanation & Hints: A WAN (wide-area network) is used to connect networks that are geographically separated and is typically owned by a service provider. The service provider contracts out WAN services to individuals and organizations.

12. What is the correct order of the layers of the TCP/IP model from the top layer to the bottom?

    • application, session, network, data link, physical
    • application, internet, network access, transport
    • network access, transport, internet, application
    • application, transport, internet, network access

19. A technician with a PC is using multiple applications while connected to the Internet. How is the PC able to keep track of the data flow between multiple application sessions and have each application receive the correct packet flows?

    • The data flow is being tracked based on the destination MAC address of the technician PC.
    • The data flow is being tracked based on the source port number that is used by each application.
    • The data flow is being tracked based on the source IP address that is used by the PC of the technician.
    • The data flow is being tracked based on the destination IP address that is used by the PC of the technician.
      

      Answers Explanation & Hints: The source port number of an application is randomly generated and used to individually keep track of each session connecting out to the Internet. Each application will use a unique source port number to provide simultaneous communication from multiple applications through the Internet.
