Refer to the exhibit.

The customer needs to expand its wired and wireless network to a new building, Building 2, which is near the
existing building, Building 1. The exhibit shows the logical plan that the architect has created so far. The
aggregation layer switches in the new building should provide the default gateway services for the VLANs in
the new building and route traffic to the core. The existing Aruba Mobility Controllers (MCs) will control the
new APs.
What should be the VLAN assignment for Link 1, indicated in the exhibit?
