Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 40

What describes the outcome when the trust boundary is defined at the Cisco IP phone?

Answer options

• A. Packets or Ethernet frames are remarked at the access layer switch.
• B. Packets or Ethernet frames are not remarked by the IP phone.
• C. Packets or Ethernet frames are not remarked at the access layer switch.
• D. Packets or Ethernet frames are remarked at the distribution layer switch.

Correct answer: C

Explanation

The correct answer is C because when the trust boundary is at the Cisco IP phone, it does not remark packets or Ethernet frames at the access layer switch, maintaining the original markings. Option A is incorrect since it suggests remarking occurs at the access layer switch, which contradicts the trust boundary concept. Options B and D also misrepresent the behavior of the IP phone and the distribution layer switch regarding packet remarking.
