NEW QUESTION 38
Fast Failover has been implemented between Local 1 and Local 2 separated by Routers. During testing Local1 was disabled and all Campus APs backed up to Local 2 flawlessly. But the RAPs did not, they all failed.
What could be the cause?
- A. The RAP whitelist must be ported over to Local 2
- B. RAPs should be configured in their own AP-groups
- C. A VPN IP Pool must be configured on Local 2
- D. IPSec must be enabled on Local 2

Answer: E
NEW QUESTION 39
An architect plans 128 APs to support 12,800 devices in a very high density (VHD) design. The customer
