Question

Why should an end user's PC device not be included within a QoS trust boundary?

A The end user could incorrectly tag their traffic to bypass firewalls.
B The end user may incorrectly tag their traffic to be prioritized over other network traffic.
C There is no reason not to include an end user's PC device in a QoS trust boundary.
D The end user could incorrectly tag their traffic to advertise their PC as a default gateway.

Explanation

End-user PCs are not generally trusted to set QoS markings correctly. A user or application could mark ordinary traffic as high priority, allowing it to be prioritized ahead of other network traffic and undermining the intended QoS policy.
