Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 53

Why would we not include an end user's PC device in a QoS trust boundary?

Answer options

• 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.

Correct answer: B

Explanation

Option B is correct because allowing end users to tag their own traffic could lead to unfair prioritization over other essential network traffic. Options A and D highlight potential issues, but they do not directly address the primary concern of traffic prioritization. Option C is incorrect as there are valid reasons to exclude end user devices from the trust boundary.
