A customer has two Cisco 550B WLCs that manage all the access points in their network and provide N+1 redundancy and load balancing. The primary Cisco WLC has 60 licenses and the secondary Cisco WLC has 40. The customer wants

to convert the N+1 model to an HA model and provide SSO. Configuration must be performed during a maintenance window. After performing all the configurations on both controllers, the config redundancy unit secondary command is issued

on the secondary Cisco WLC and it fails.

Which parameter needs to be in place to complete the configuration?

A. A cable in the RP port

B. The secondary Cisco WLC needs a minimum of 50 base licenses

C. The primary Cisco WLC is already set as the secondary unit.

D. SSO needs to be enabled

A customer has two Cisco WLCs configured in a SSO cluster. The wireless network supports a large warehouse. The customer purchases new iPads to replace legacy scanners. Both devices connect to a single SSID named Scanning by using WPA2 Personal. The customer wants to use a standards-based method for fast roaming on the new iPads. Which approach meets the scanner requirement and still supports the legacy scanners?

A. Enable FT PSK and set Fast Transition to Adaptive for the Scanning SSID.

B. Enable FT 802.1X and set Fast Transition to Adaptive for the Scanning SSID.

C. Enable optimized roaming globally and enable FT 802.1X on the Scanning SSID.

D. Enable optimized roaming globally and enable FT PSK on the Scanning SSID.
