Question

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

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.

Explanation

A Cisco IP phone marks its voice and attached-device traffic before it reaches the access switch. When the phone is the trusted boundary, the access-layer switch preserves those received QoS markings instead of remarking the packets or Ethernet frames.
