NEW QUESTION # 77
You suspect an interfere may exist in a BSS that is experiencing sporadic problems. You want to identify and locate the device. The actual device identify is not known.
What tool should be used for this purpose?

A. Throughput tester
B. Protocol analyzer
C. Cable tester
D. Spectrum analyzer

Answer: D

NEW QUESTION # 78
In the frame decode shown, there are two sets of supported data rates. 1, 2, 5.5, and 11 Mbps are all shown as "basic" data rates, and 6, 9, 12, 18, 24, 36, 48, and 54 Mbps are shown simply as supported data rates.

What is true of "basic" data rates in this context?

A. Basic rates are only used for multicast traffic, and do not affect unicast traffic.
B. Basic rates are defined in an AP's service set to specify mandatory data rates for all retry frames.
C. The highest data rate set to Basic is automatically used to send broadcast traffic such as Beacon frames.
D. Basic rates are optional data rates for the BSS, often used for assuring connectivity for legacy stations.
E. The AP requires all client stations to support Basic rates in order to associate to its BSS.

Answer: E
