Question3: Refer to the exhibit.

Controllers are configured in a cluster as shown in the exhibit. These are the network details.
-AMobility Master (MM) managers the cluster.
-The cluster contains two controllers: C1 and C2.
-AP1 and AP2 use C1 as their Active AP Anchor Controller (A-AAC), with C2 as their Standby AAC (S-AAC).
-AP3 and AP4 use C2 as their A-AAC with, C1 as their S-AAC.
User1 establishes a wireless connection via AP1, where the Active User Controller (U-UAC) assigned is C1, with C2 as the standby. What happens when User1 roams the wireless network and eventually their session is handled by AP3?
