• Question 21
1 out of 1 points

Suppose that you need to set up an autonomous AP so that it will offer three different SSIDs to clients. The AP will be connected to a wired network infrastructure. Which one of the following is a true statement about the AP?.

• Question 22
1 out of 1 points

All the APs on the second floor of a building are part of a single ESS. Each AP has been configured with a transmit power level of 14 dBm. In addition, each AP has been configured to use a non-overlapping channel that is different from its adjacent neighbors. All APs have been configured to offer only the 24-, 36-, 48-, and 54-Mbps data rates; all other rates are disabled. One day, one of the APs fails and someone replaces it. Afterward, users begin to call and complain about poor performance and roaming. You discover that the problems are not occurring in the area covered by the replacement AP; instead, they are occurring about two APs away from it. Which one of the following could be causing the problem?
Selected Answer: The replacement AP is using the 1- and 2-Mbps data rates.
