• Question 16:

  This question requires that you evaluate the underlined text to determine if it is correct.

  The query protocol used to locate resources on a network is User Datagram Protocol (UDP).

  Review the underlined text. If it makes the statement correct, select "No change is needed." If the statement is incorrect, select the answer choice that makes the statement correct.

• Question 18:

  What happens when an 802.11a node broadcasts within the range of an 802.11g access point?

  A. The access point transmits, but the node is unable to receive.

  B. A connection occurs.

  C. Both the node and the access point are unable to transmit.

  D. The node transmits, but the access point is unable to receive.

  Correct Answer: D

  Because 802.11a and 802.11b utilize different frequencies, the two technologies are incompatible with each other.

  A huge problem with 802.11a is that it's not directly compatible with 802.11b or 802.11g networks. In other words, a user equipped with an 802.11b or 802.11g radio card will not be able to interface directly to an 802.11a access point.

  Reference: Making the Choice: 802.11a or 802.11g

• Question 19:

  This question requires that you evaluate the underlined text to determine if it is correct.

  The "NTP" value in a resource record indicates a length of time that other DNS servers use to determine how long to cache information for a record before expiring and discarding it.

  Select the correct answer if the underlined text does not make the statement correct. Select "No change is needed'' if the underlined text makes the statement correct.

  A. TTL

  B. GPS

  C. SOA RR

  D. No change is needed

  Correct Answer: A

  Time to live (TTL) is what dictates how long it will be until your computer refreshes its DNS related information.

• Question 20:

  This question requires that you evaluate the underlined text to determine if it is correct.

  Each IPv4 address consists of a "MAC address and data-link laver address".

  Select the correct answer if the underlined text does not make the statement correct. Select "No change is needed" if the underlined text makes the statement correct.

  A. Network ID and a host ID

  B. DNS record and a default route

  C. 64-bit binary number divided into octets

  D. No change is needed

  Correct Answer: A

  Each IP address is separated internally into two parts--a network ID and a host ID.
