Refer to the exhibit. An administrator implements the MultiZone feature. The administrator sets up five zones as shown in the exhibit in this configuration:

• Zone A has six controllers that form a cluster.
• Zone B has three controllers that from a cluster.
• Zones C, D, and E have a single standalone controller each.

A total of 13 VAPs are created across the five zones. Aruba Mobility Controllers (MCs) in Zones A, B and C run ArubaOS 8.1.0.1 MCs in zones D and E run ArubaOS 8.1.0.2. Some APs do not join their respective data zones. What could cause this problem?
