Microsoft 98-366 Online Questions & Answers

• Question 1:

  A cable that meets the l000BaseT standard has a maximum length of:

  A. 100 m
  B. 250 m
  C. 500 m
  D. 1,000 m
  A. 100 m

  ---

  When used for 10/100/1000BASE-T, the maximum allowed length of a Cat 6 cable is 100 meters or 328 feet.

• Question 2:

  What are two characteristics of the CSMA/CD access method? (Choose two.)

  A. It checks to see if a collision has been detected.
  B. It does a round robin search for requests to transmit from all nodes on the network.
  C. It signals its intent to transmit on the network.
  D. It waits until the transmission medium is idle.
  A. It checks to see if a collision has been detected.
  D. It waits until the transmission medium is idle.

  ---

  Main procedure for the CSMA/CD:

  1.

  Is my frame ready for transmission? If yes, it goes on to the next point.

  2.

  Is medium idle? If not, wait until it becomes ready

  3.

  Start transmitting.

  4.

  Did a collision occur? If so, go to collision detected procedure.

  5.

  Reset retransmission counters and end frame transmission.

  Note:

  Carrier Sense Multiple Access With Collision Detection (CSMA/CD) is a media access control method used most notably in local area networking using early Ethernet technology. It uses a carrier sensing scheme in which a transmitting data

  station detects other signals while transmitting a frame, and stops transmitting that frame, transmits a jam signal, and then waits for a random time interval before trying to resend the frame.

• Question 3:

  Which of these addresses is a multicast address?

  A. 127.0.0.1
  B. 169.254.0.1
  C. 192.168.0.1
  D. 224.0.0.1
  D. 224.0.0.1

  ---

  The full range of multicast addresses is from 224.0.0.0 to 239.255.255.255.

• Question 4:

  A VPN is a/an:

  A. Encrypted connection across the Internet.
  B. Virtual network within your local area network (LAN).
  C. Communication tunnel between VLANs.
  D. Personal network for your use only.
  A. Encrypted connection across the Internet.

  ---

  VPN is a network that is constructed by using public wires -- usually the Internet -- to connect to a private network, such as a company's internal network.

  There are a number of systems that enable you to create networks using the Internet as the medium for transporting data. These systems use encryption and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted.

• Question 5:

  What are two characteristics of wired Ethernet network topology? (Choose two.)

  A. It uses network adapters physically encoded with an IP address
  B. It uses tokens to avoid collisions on the network
  C. It is typically employed using twisted pair of fiber optic media D. It can negotiate different transmission speeds
  A. It uses network adapters physically encoded with an IP address

• Question 6:

  Attenuation in a wireless network signal is a result of:

  A. Number of wireless nodes connected.
  B. Distance from the access point.
  C. Interference from cellular phones.
  D. Encryption of the signal.
  B. Distance from the access point.

  ---

  Solid objects greatly attenuate (reduce) Wi-Fi radio signals, so clear line of sight is best.

• Question 7:

  A characteristic of the mesh topology is that it:

  A. Uses a central hub.
  B. Cannot use wired connections.
  C. Uses redundant paths.
  D. Cannot use wireless connections.
  C. Uses redundant paths.

  ---

  Mesh network topology is one of the key network architectures in which devices are connected with many redundant interconnections between network nodes such as routers and switches. In a mesh topology, if any cable or node fails, there are many other ways for two nodes to communicate.

• Question 8:

  Which network device interconnects computers in a workgroup, is able to be remotely configured, and provides the best throughput?

  A. Unmanaged switch
  B. Hub
  C. Router
  D. Managed switch
  D. Managed switch

  ---

  Managed switches ?these switches have one or more methods to modify the operation of the switch. Common management methods include: a command-line interface (CLI) accessed via serial console, telnet or Secure Shell, an embedded

  Simple Network Management Protocol (SNMP) agent allowing management from a remote console or management station, or a web interface for management from a web browser.

  Incorrect:

  not A: Unmanaged switches are basic plug-and-play switches with no remote configuration, management, or monitoring options, although many can be locally monitored and configured via LED indicators and DIP switches.

  Not B: Hubs cannot be managed.

  Not C: Switches are faster than routers.

• Question 9:

  You run the ipconfig command. The output is shown in the following image:

  

  From these settings, you can tell that the computer:

  A. Will have limited Internet access
  B. Will have full Internet access
  C. Will not be able to access the Internet
  D. Will not be able to access the local network
  A. Will have limited Internet access

• Question 10:

  A computer that has an IP address of 169.254.0.1 cannot access the network. Which of the following services should you confirm is available?

  A. WINS
  B. DNS
  C. DHCP
  D. TFTP
  C. DHCP

  ---

  169.254.0.1 is an APIPA address. An APIPA address is used when the DHCP server is not available.
