A customer uses an SIP application that is not supported by Aruba United Communications and Collaboration (UCC). Which voice deployment mode should the administrator implement on Aruba Mobility Controllers (MCs) to support this application?

An administrator supports Aruba Mobility Controllers (MCs) managed by a Mobility Master (MM) in a noncluster 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 group of users on the same floor of a campus residence experience connectivity problems continuously throughout the morning. The administrator suspects that it is a L1 problem with physical interference.
What can the administrator do to find the cause of this problem?

An administrator wants to implement the MultiZone feature in a company's network to segregate corporate and guest traffic. Corporate traffic will have APs establish connections to a cluster managed by a Mobility Master (MM), and guest traffic will have the same APs establish connections to a standalone controller at the company's DMZ.
What is true about the implementation of MultiZones in this scenario?

An administrator supports a cluster of four Aruba Mobility Controllers (MCs) with management addresses of
10.1.100.101, 10.1.100.102, 10.1.100.103, and 10.1.202.181. The administrator accesses an AP associated with thiscluster, reboots it and accesses apboot mode. The administrator executes the printenv command.
Which AP parameter contains the IP addresses of the cluster members that the AP should use to connect to the cluster?
