Which controller connection with the Aruba as the cluster leader?

Which RAP WLAN operation mode should an administrator configure if the SSID should only be advertised if controller connectivity is lost?

Refer to the exhibit.

Controllers are configured in a cluster as shown in the exhibit. These are the network details.
-A Mobility 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?

An administrator supports Aruba Mobility Controllers (MCs) managed by a Mobility Master (MM) in a non- cluster deployment. The administrator performs these tasks on the MM for the MCs:
* Enables L3 IP mobility for the respective VAPs on the MCs
* Creates a L3 domain and places the MCs in the domain
However, roaming does not work when users roam from an AP connected to one controller in the domain to an AP connected to a different controller in the domain.
What must the administrator do to fix this problem?

A company opens a new branch office and a RAP is used to connect to a corporate office Aruba Mobility Controller (MC). The company needs to provide connectivity to the office across the street. There is an AP across the street. However, there is no wired connectivity between the buildings.
Which actions can the administrator select to provide the required connectivity? (Choose two.)
