When using a protocol analyzer to capture conversations over a WLAN, you may often encounter encrypted data frames. Most WLAN protocol analyzers have a feature that allows the analyst to save and reload the captured frames into memory at a later time. Using this functionality, what task can be performed?

A.
When IEEE 802.1X/LEAP is being used as the WLAN security mechanism, the authentication response frame can be replayed from a saved trace file at a later time to successfully authenticate a hacker.

B.
If a user name and password for an IEEE 802.1X/EAP-TTLS security implementation can be obtained through social engineering tactics, the user name and password can be entered into the analyzer to decrypt the frames from a saved trace file.

C.
An analyst can search through the captured frames looking for RADIUS frames that will disclose the user’s password.

D.
Encrypted frames may be decrypted offline, after they are captured, by entering a WEP key or WPA passphrase into the analyzer.
