• Question 64:

  Which approach is taken to implement CAC within Cisco UCM in full-mesh topology?

  A. physical location

  B. Audio Codec Preference List

  C. RSVP-enabled locations

  D. device pool

  Correct Answer: C

• Question 65:

  Refer to the exhibit.

  

  A customer wants the SIP 200 OK shown to advertise codecs in the following order:

  1.

  G.729

  2.

  G.711u

  3.

  G.711a

  4.

  G.723

  After correcting the codec preferences. What should the audio payload show in the SIP Traces?

  A. m=audio 0 RTP/AVP 0 8 18 4 15

  B. m=audio 0 RTP/AVP 4 0 8 18 15

  C. m=audio 0 RTP/AVP 0 18 8 4 15

  D. m=audio 0 RTP/AVP 18 0 8 4 15

  Correct Answer: D

  You could probably get thru the test just knowing the payload IDs for G.711u being 0 and G.729 being 18.

  G.729 = 18 G.711u= 0 G.711a = 8

  G.723 = 4

  G.728 = 15
