If you are not ready to take this test, you can study here.
Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

1. What kind of mgmt frames does client mfp protect
1. disassociation 2. deauthentication 3.QoS (WMM)
1. Integrated -- wIPS monitor mode aps are part of client-serving infrastructure 2. Overlay -- wIPS aps - WCS & WLCs are totally seperate
1. User performs .1x with RADIUS 2. WLC forwards radius accounting start to NAM (along with clients IP) 3. clients NAA detects network con. & tries to connect to NAM. 4. NAS Intercepts step 3 & contacts NAM itself to see if client is in the online li
specifies fast bss transitions by allowing negotiations and requests for wireless resources to occur simultaneously. Does this by allowing for part of the key to be cached (server key) among the network - so full 802.1x auth. isnt required

2. What is the WLAN-->Advanced--> DIagnostic Channel used for
when you want some wlcs to be part of the same mobility group - but not others.
after .1x authentication user is forwarded to a splash page. This is done via RADIUS attribute
puts the ap and client through tests to isolate connection issues. This disables the wlan while doing this. Can be used to diagnose .1x auth - .11 association etc. if using ccxv5
mititgate non-802.11 attacks

3. WLC Tacacs+ roles
