• Question 436:

  Refer to the exhibit.

  

  An engineer is troubleshooting a codec negotiation issue where both endpoints that are involved in the call support the codecs listed in the exhibit.

  Which audio codec is selected il a call between two endpoints in Region 1 is placed?

  A. G.711u
  B. G.722
  C. G.729
  D. G.711a
  B. G.722

  Explanation

  In the picture from the drop-down list (Codecs in List*) it is indicated that the codec is 722 use 48k.

• Question 437:

  To provide high-quality voice and take advantage of the full voice feature set, which two access layer switches provide support? (Choose two.)

  A. Use multiple egress queues to provide priority queuing of RTP voice packet streams and the ability to classify or reclassify traffic and establish a network trust boundary.
  B. Deploy RSVP to improve VoIP QoS only where it can 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 and AF42) to a class-based queue with weighted random early detection.
  D. Use 802.1Q trunking and 802.1Q for proper treatment of Layer 2 CoS packet marking on ports with phones connected.
  E. Implement IP RTP header compression on the serial interface to reduce the bandwidth required per voice call on point-to-point links.
  A. Use multiple egress queues to provide priority queuing of RTP voice packet streams and the ability to classify or reclassify traffic and establish a network trust boundary.
  D. Use 802.1Q trunking and 802.1Q for proper treatment of Layer 2 CoS packet marking on ports with phones connected.

  Explanation

  To provide high-quality voice and to take advantage of the full voice feature set, access layer switches should provide support for:

  1. 802.1Q trunking and 802.1p for proper treatment of Layer 2 CoS packet marking on ports with phones connected 2. Multiple egress queues to provide priority queuing of RTP voice packet streams

  3. The ability to classify or reclassify traffic and establish a network trust boundary 4. Inline power capability (Although inline power capability is not mandatory, we highly recommend for the access layer switches.)

  5. Layer 3 awareness and the ability to implement QoS access control lists (These features are required if you are using certain IP telephony endpoints, such as a PC running a softphone application, that cannot benefit from an extended trust boundary.)
