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. Enhanced Neighbor list
is provided to clients as they associate - including neighbor ap info like channel - rssi etc.
1. WLC must be defined as a VPN Conentrator - in the NAC config. 2. WLC must be configd to send RADIUS acct. to NAC
a mobility list can contain multiple mobility groups
what occurs as a client roams to new ap -WLC forwards cached PMK to AP. Client then forms a Pairwise Transient Key (PTK) via 4-way handshake w/ ap.

2. What kind of mgmt frames does client mfp protect
1. NAC Guest Server (NGS) - Like a RADIUS server when people can create guest accounts 2. Nac Manager (NAM) - Centrilized server for creating policies & profiles that determine network access. 3. Network Access Server (NAS) - The device which control
