Question
A hospital has a Cisco Catalyst 9800 Series Wireless Controller in a SSO solution deployed to the primary data center. The hospital plans to increase redundancy in the wireless environment. Management decides to deploy an extra Catalyst 9800 WLC offsite to another data center on a different subnet. A WAN link connects the data centers with a firewall at both ends. Which two design approaches must the engineer take to ensure that the APs can fail over? (Choose two.)
Options
- ACreate a mobility group with the same names on both wireless controllers.
- BCreate a static RF group leader on one of the wireless controllers.
- CCreate a mobility tunnel between the wireless controllers.
- DOpen HTTPS port 443 between the wireless controllers.
- EOpen UDP ports 16666 and 16667 between the wireless controllers.

Explanation
Create a mobility group with the same names: For an AP to successfully fail over and join a secondary/tertiary WLC in a different physical location, both WLCs must share the same Mobility Group Name. This is fundamental for the AP to identify the alternate controller as a valid failover Open UDP ports 16666 and 16667: These are the default ports for the Mobility Protocol Control and Data paths. They must be open on the firewalls separating the data centers to allow the WLCs to communicate for mobility messaging, which is essential for RF group formation and AP failover coordination.
