NEW QUESTION # 36
Refer to the exhibit. An enterprise is using wireless as the main network connectivity for clients. To ensure service continuity. a pair of controllers will be installed in a datacentre. An engineer is designing SSO on the pair of controllers. What needs to be included in the design to avoid having the secondary controller go into maintenance mode?
- A. The connection between the redundancy ports is missing.
- B. The redundancy port must be the same subnet as the redundancy mgmt.
- C. The Global Configuration of SSO is set to Disabled on the controller.
- D. The Keep alive timer is too low. which causes synchronization problems.
Answer: A
Explanation:
'There are few scenarios where the Standby WLC may go into Maintenance Mode and not be able to communicate with the network and peer: * Non reachability to Gateway via Redundant Management Interface * WLC with HA SKU which had never discovered peer * Redundant Port is down * Software version mismatch (WLC which boots up first goes into active mode and the other WLC in Maintenance Mode)' High Availability (SSO) Deployment Guide - Cisco
