Microsoft 98-366 Online Questions & Answers

• Question 21:

  The service that resolves fully qualified domain names (FQDN) to IP addresses is:

  A. Windows Internet Name Service (WINS).
  B. Domain Name Service (DNS).
  C. Internet Service Provider (ISP).
  D. Address Resolution Protocol (ARP).
  B. Domain Name Service (DNS).

  ---

  The DNS translates Internet domain and host names to IP addresses. DNS automatically converts the names we type in our Web browser address bar to the IP addresses of Web servers hosting those sites.

• Question 22:

  Which protocol is a transport layer protocol?

  A. FTP
  B. IP
  C. UDP
  D. ASCII
  C. UDP

  ---

  Transport layer protocols include: UDP, TCP

• Question 23:

  What are two differences between switches and hubs? (Choose two.)

  A. Switches are slower than hubs because of the extra addressing functions that switches perform.
  B. Switches send data to all of the computers that are connected to them for efficiency.
  C. Switches are capable of sending and receiving data at the same time.
  D. Switches identify the intended destination of the data that they receive.
  A. Switches are slower than hubs because of the extra addressing functions that switches perform.
  D. Switches identify the intended destination of the data that they receive.

  ---

  Hubs repeat everything they receive and can be used to extend the network.

  Switches control the flow of network traffic based on the address information in each packet. A switch learns which devices are connected to its ports (by monitoring the packets it receives), and then forwards on packets to the appropriate port

  only. This allows simultaneous communication across the switch, improving bandwidth.

• Question 24:

  Teredo tunneling is a protocol that:

  A. Translates Internet Protocol version 4 (IPv4) to Internet Protocol version 6 (IPv6).
  B. Allows IPv6 connectivity through IPv4 devices.
  C. Provides VPN security.
  D. Dynamically allocates IPv6 addresses.
  B. Allows IPv6 connectivity through IPv4 devices.

  ---

  Teredo alleviates this problem by encapsulating IPv6 packets within UDP/IPv4 datagrams, which most NATs can forward properly. Thus, IPv6-aware hosts behind NATs can be used as Teredo tunnel endpoints even when they don't have a dedicated public IPv4 address.

• Question 25:

  What are two advantages of using star topology rather than ring topology in a computer lab workgroup? (Choose two.)

  A. Failure of a central connectivity device does not bring down the entire network.
  B. A central connection point allows for flexibility and scalability.
  C. Data travels on redundant paths, so one cable cannot stop its transmission.
  D. A cable problem within the group affects two nodes, at most.
  B. A central connection point allows for flexibility and scalability.
  D. A cable problem within the group affects two nodes, at most.

• Question 26:

  Security is a concern on wireless networks due to:

  A. The radio broadcast access method.
  B. Spread spectrum issues.
  C. Frequency modulation issues.
  D. The potential for cross-talk.
  A. The radio broadcast access method.

• Question 27:

  Which utility would you use to determine if your Domain Name System (DNS) server is properly resolving fully qualified domain names (FQDNs) as IP addresses?

  A. netstat
  B. nslookup
  C. nbtstat
  D. ipconfig
  D. ipconfig

• Question 28:

  HOTSPOT

  For each of the following statements, select Yes if the statement is true. Otherwise, select No. Each correct selection is worth one point.

  Hot Area:

  

  

• Question 29:

  HOTSPOT

  For each of the following statements, select Yes if the statement is true. Otherwise, select No. Each correct selection is worth one point.

  Hot Area:

  

  

• Question 30:

  Which wireless authentication method provides the highest level of security?

  A. Wired Equivalency Privacy (WEP)
  B. IEEE 802.lln
  C. WI-FI Protected Access (WPA)
  D. IEEE 802.11a
  C. WI-FI Protected Access (WPA)

  ---

  WPA aims to provide stronger wireless data encryption than WEP.

  Wi-Fi Protected Access (WPA) is a security protocol and security certification program developed by the Wi-Fi Alliance to secure wireless computer networks.
