Exhibit 2

A company wants to deploy an Aruba solution with a master controller and a local controller along with 120 APs. The wireless clients in VLANs 55 and 20 are deployed in Layer 2 mode. The company has these requirements:
The wireless clients should use the existing wired backbone to access DHCP, DNS, and authentication

servers.
Controllers should be connected in a backbone switch that is configured to allow all VLANs.

A network engineer designs and deploys the solution to meet the company requirements. During the testing phase, the engineer determines that wireless clients are not able to get the IP address from the DHCP server on the network backbone.
Based on the output shown in the exhibit, what should the engineer do to solve the issue?
