Refer to the exhibit.
On basis of the configuration that is provided, where will the trust boundary be established in this network?
A.
at the PC
B.
at the access switch
C.
at the IP phone
D.
at the distribution switch
Explanation:
The example shown is a properly configured switch where the trust boundary is being set at
the access port on the switch itself. The “switchport voice vlan vlan-id dot1q” command
enables voice VLAN on switch port and associated VLAN.
The “mls qos trust cos” command enables QoS (Quality of Services ) based on COS (Class
of service).
The “switchport priority cos <priority>” value sets the priority values to frame coming from PC
to switch port.
