Question 80/301

The network administrator receives complaints of slow wireless network performance and performs a sniffer trace of the wireless network in preparation for migration to 802.11n. The sample capture shows frames that contains AP beacons with NonERP_Present bit set to 1 and frames with RTS/CTS. Which two conclusions can be interpreted from these frames? (Choose two.)

A. The network is performing slowly because 802.11n clients are already mixed with 802.11g clients.

B. The network is performing slowly because 802.11b clients still exist in the network.

C. The network is performing slowly because a wireless client is incorrectly configured, which results in RF interference.

D. Possible 802.11b wireless clients are located only in the AP cell radius where the sniffer capture was performed.

E. Possible 802.11b wireless clients could be located anywhere in the wireless network.
