Question 5
How does AP failover priority for access points function when configured with priority 1 or 4?

The APs in location A are statically configured to use controller A as the primary and controller B as the secondary.

- B: Change the AP Failover Priority to critical.
- C: Use DHCP Option 43 and specify WLC in location A as primary.
