An engineer is designing a wireless network that will support many different types of wireless clients. When conducting the survey, which client must be used to ensure a consistent experience for all of the wireless clients?

Which statement about the 9800 Series Wireless Controller mobility tunnel on a Cisco Catalyst
9800 controller is true?

Clustering Cisco WLCs into a single RF group enables the RRM algorithms to scale beyond the capabilities of a single Cisco WLC.
How many WLC and APs in an RF group can the controller software scale up to in WLC release
8.9 depending on the platform?

An architect configures a set of AirOS controllers to be in the same mobility group as the existing controllers. The implementation should facilitate inter-controller roaming for users in their new campus. After the configuration, the mobility tunnel is not operational for the data path in the network. Which two validations should be performed? (Choose two.)

A customer has this wireless design:
- two Cisco Catalyst 9800 Series wireless controllers configured in a
high-availability SSO cluster to manage APs in the local office network
- 100 APs in local mode and registered to the high-availability cluster
- one Catalyst 9800 Series wireless controller that is deployed as an
anchor in a DMZ
- Cisco ISE for user authentication and authorization
The customer wants to deploy a new SSID to support staff BYOD devices and authenticate users via Cisco ISE. The SSID terminates on the anchor WLC. How must the requirement be incorporated into the design to address the AAA servers for the WLAN?
