Refer to the exhibit.
Network topology

Currently the HP MSM720 Controller shown in the exhibit is operating at its factory default settings
except for the VLAN ID on the access network. Other ports have their factory default, VLAN
assignments. Now a network administrator change the internet network VLAN ID to 20. The
network administrator assigns this profile as a tagged VLAN on port 2 and connects the port to the
core switch. The network administrator loses to access to the controller.
What is the most likely cause of the problem?

A.
A routing loop between the controller’s ports

B.
The controller handing out invalid DHCP addresses

C.
The controller capturing traffic and directing it to its internal public access interface.

D.
A broadcast storm

Explanation:

Because the two ports arise in the same subnet, a routing loop occurs.
