10. Which statement about AP failover priority for access points when configured with priority 1 or 4 is true?

When configured with priority 1, the access point is assigned with the highest priority level and it is marked as critical. This access point fails over before other access points with the lower priority when there is primary controller failure.

When configured with priority 4, the access point is assigned with the highest priority level and it is marked as critical. This access point fails over before other access points with the lower priority when there is primary controller failure.

When configured with priority 4, the access point is assigned with the lowest priority level and it is marked as low. This access point fails over after other access points with the higher priority when there is primary controller failure.

When configured with priority 1, the access point is assigned with the medium priority level and it is marked as medium. This access point fails over after other access points with the higher priority when there is primary controller failure.

Which two requirements complete This design? (Choose two)

Site access

AP model

WLC model

HAVC access

Number of clients

14. APs in a remote office recently have been converted from local mode to FlexConnect to take advantage of the local switching. After the change, remote wireless users report voice quality issues and bad quality on wireless IP phones while roaming. A debug is performed, and it is noticed that the 802.11r Fast Transition is not working as expected, like on local mode AP, though the same WLAN configuration is in place.

What is the cause of the issue regarding the FlexConnect APs?

They do not support 802.11r F

They must be added into AP groups along with a common RF profile.

They must be in a FlexConnect group to support 802.11r F

They must be added to AP groups to support fast roaming methods.
