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:

Which command will create a dynamic pool named Todd that will provide you with 30 global addresses?

A) ip nat pool Todd 171.16.10.65 171.16.10.94 net 255.255.255.240	B) ip nat pool Todd 171.16.10.65 171.16.10.94 net 255.255.255.224
C) ip nat pool todd 171.16.10.65 171.16.10.94 net 255.255.255.224	D) ip nat pool Todd 171.16.10.1 171.16.10.254 net 255.255.255.0

Answer & Explanation Answer: B) ip nat pool Todd 171.16.10.65 171.16.10.94 net 255.255.255.224

Explanation:

The command ip nat pool name creates the pool that hosts can use to get onto the global internet. What makes option B correct is that the range 171.16.10.65 through 171.16.10.94 includes 30 hosts, but the mask has to match 30 hosts as well, and that mask is 255.255.255.224 . Option C is wrong because there is a lowercase t in the pool name. Pool name are case sensitive.

Answer & Explanation Answer: C) Add the source addres and port to the MAC address table and forward the frame out the destination port

Explanation:
