Q:

A wireless client cannot connect to an 802.11b/g BSS with a b/g wireless card. The client section of the access point does not list any active WLAN clients. What is a possible reason for this?

A) The incorrect channel is configured on the client B) The Client's IP address is on the wrong subnet
C) The client has an incorrect pre-shared key D) The SSID is configured incorrectly on the client
 
Answer & Explanation Answer: D) The SSID is configured incorrectly on the client

Explanation:

Although this question is cryptic at best, the only possible answer is option D. If the  SSID is not being broadcast (which we must assume in this question), the client must be configured with the correct SSID in order to associate to the AP.

Q:

Your inside locals are not being translated to the inside global addresses. Which of the following commands will show you if your inside globals are allowed to use the NAT pool?
