A technician is troubleshooting a client’s connection to a wireless network. The client is asked to run a “getinfo” command to list information about the existing condition.
myClient$ wificard –getinfo agrCtlRSSI:-72 agrExtRSSI:0 state:running
op mode: station lastTxRate:178 MaxRate:300
802.11 auth:open link auth:wpa2-psk

Given this output, which of the following has the technician learned about the wireless network? (Select TWO).

A. The WAP is using RC4 encryption
B. The WAP is using 802.11a
C. The WAP is using AES encryption
D. The WAP is using the 2.4GHz channel
E. The WAP is using the 5GHz channel
F. The WAP is using 802.11g

Correct Answer: CE

WPA2 makes use of the Counter Mode with Cipher Block Chaining Message Authentication Code Protocol (CCMP) encryption protocol, which is an AES based protocol.
The output shows that the wireless network operates on channel 149, which is a channel in the 5GHz band.
