Which three statements about the high availability configuration on the Cisco 5760 WLCs are true? (Choose three.)
Click on the arrows to vote for the correct answerA. B. C. D. E. F.
The correct answers are B, C, and E.
A. This statement is not true. The Cisco WLC with the highest priority is elected as the active WLC during the election process, not the one with more reboots.
B. This statement is true. Active Cisco WLCs in a pair can be identified using the LED state without issuing any command on the Cisco WLC console. When the active WLC is operating normally, the SYS LED is green, while the STBY LED is off. If the active WLC fails, the standby WLC takes over, and the SYS LED on the standby WLC turns green, while the STBY LED turns amber.
C. This statement is true. The Cisco 5760 WLC uses a dedicated high availability port for high availability and configuration synchronization. This port is used to exchange keepalive messages, Heartbeat messages, and configuration information between the active and standby WLCs.
D. This statement is not true. While the configuration is automatically synced between the active and standby Cisco WLC, certificates are not automatically synced. Certificates must be manually copied from the active WLC to the standby WLC.
E. This statement is true. The Cisco WLC with the highest priority in a stack is elected as the active Cisco WLC during the election process. By default, the priority value of the WLC is 1. You can manually assign a priority value between 1 and 16 to each WLC in the stack. The WLC with the highest priority value becomes the active WLC.
F. This statement is not true. EitherChannel is not used to bundle all ports on both active and standby Cisco WLCs on a logical port. EitherChannel is used to bundle two physical ports on a single WLC into a logical port to increase the bandwidth between the WLC and the switch. To provide redundancy between the active and standby WLCs, you can use EtherChannel with LACP to bundle the high availability and management ports on both WLCs.
