Which two features will access layer switches provide support providing high-quality voice and taking advantage of the full voice feature set? (Choose two.)

A.

Deploy RSVP to improve VoIP QoS only where it will have a positive impact on quality and functionality where there is limited bandwidth and frequent network congestion.

C.

Map audio and video streams of video calls (AF41 andAF42) to a class-based queue with weighted random early detection.

D.

Implement IP RTP header compression on the serial interface to reduce the bandwidth required per voice call on point-to-point links.

E.

Use 802 1Q trucking and 802.1p for proper treatment of Layer 2 CoS packet marking on ports with phones connected.
