Implementing Cisco Enterprise Wireless Networks (ENWLSI) v1.1 Quiz Questions and Answers

Answer :
  • Passive survey

Explanation :

A passive site survey would provide all of the information needed. Because the passive survey tool listens to all APs that are in range of a location, you would learn of legitimate and rogue APs as well as the RF conditions.
Answer :
  • A client must send all frames through the AP to reach any other client or coordinate with the AP to reach another client directly.

Explanation :

In a BSS, the 802.11 standard requires all traffic to pass through an AP. The only exception is the 802.11z amendment, which permits an AP to coordinate direct client-to-client traffic without passing through the AP.
Answer :
  • Through the AP only

Explanation :

Client-to-client traffic typically passes through an autonomous AP, although clients can use Direct Link Setup (DLS) to communicate directly after coordinating with the AP.
Answer :
  • Multipath

Explanation :

By switching to a less-complex modulation scheme, more of the data stream can be repeated to overcome worsening RF conditions. This can be done automatically through DRS.
Answer :
  • Switch to a less-complex modulation scheme

Explanation :

By switching to a less-complex modulation scheme, more of the data stream can be repeated to overcome worsening RF conditions. This can be done automatically through DRS.
Answer :
  • Absorption

Explanation :

As a signal is reflected, a new copy travels in a different direction. Each copy of the signal takes a different path to reach the receiver; thus, the name multipath.
