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
BSSID: 0F:33:AE:F1:02:0A
SSID: CafeWireless
Channel: 149,1
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
Explanation:
Can someone enlighten me why E is the answer here?
The channel in use is 149, which is in the 5ghz range. Channels in 2.4ghz range from 1-13 while in 5ghz they range from 7-196. I’m not sure if the 1 indicates both channels are in use or something else though.
why is it C?
It’s C because of the designation of WPA2-PSK under link auth. Most modern routers have WPA2-PSK/AES due to the now obsolete WPA2-PSK/TKIP, which isn’t very secured. So the two indicators here are under link auth and channel for the answer of this question.
Channel 1 exists in the 2.4GHz spectrum
