A customer Wi-Fi deployment is experiencing the sticky client problem and must enable the optimized roaming feature. The wireless clients have valid security credentials for an SSID and can see an AP that offers that SSID to join. What must be configured to enhance roaming?

A customer has this wireless design at its main branch:
- two Cisco Catalyst 9800 Series wireless controllers named WLC-Aand
WLC-B in an N+1 configuration
- the same WLANs with different Layer 3 interfaces for each WLC
- 100 APs in local mode
WLC-A manages the APs for a building named Building A. WLC-B manages the APs for a building named Building B. The customer wants to ensure that users can remain connected and retain their session state, including the IP address, when they move between buildings. How must this requirement be incorporated into the design?

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 customer has two Cisco wireless controllers named WLC-A and WLC-B. Each controller is in a different building on a campus. The WLCs have different Layer 3 interfaces and broadcast the same SSIDs from their respective APs. Users must remain connected to the same VLAN and maintain their IP addresses during roaming from the APs that are attached to WLC-A and WLC B.
Which action accomplishes the requirement?

An engineer is performing an AP-on-a-stick survey and -nds that the 5 GHz channel overlap is too high when an appropriate number of APs are used for the density requirements. Which two actions during the survey reduce channel overlap? (Choose two.)
