  A. audio call

  B. messaging

  C. video call

  D. signalling

  Correct Answer: C

• Question 72:

  Refer to the exhibit. Which codec should an engineer select for a call mode between "Dallas-REG" and "Austin-REG"?

  

  A. MP4A-LATM

  B. G.729

  C. OPUS

  D. G.711

  Correct Answer: B

  The codec preference list for the "Dallas-REG" region is "Factory Default low loss". This list includes the following codecs in order of preference:

  G.729

  G.711 OPUS MP4A-LATM The codec preference list for the "Austin-REG" region is "Factory Default low loss". This list includes the following codecs in order of preference:

  G.729

  G.711 OPUS MP4A-LATM Since both regions have the same codec preference list, the codec that will be used for a call made between "Dallas-REG" and "Austin-REG" is G.729. G.729 is a narrowband speech codec that was developed by the ITU-T in 1988. It is a low- bitrate codec that provides good quality speech at a bitrate of 8 kbps. G.729 is widely used in VoIP applications and is the default codec for many VoIP systems. G.711 is a wideband speech codec that was developed by the ITU-T in 1972. It is a high- bitrate codec that provides excellent quality speech at a bitrate of 64 kbps. G.711 is not as widely used as G.729 due to its high bitrate requirements. OPUS is a lossy audio codec that was developed by the IETF in 2012. It is a low-bitrate codec that provides good quality speech at a bitrate of 6 kbps. OPUS is widely used in VoIP applications and is the default codec for many VoIP systems. MP4A-LATM is a lossy audio codec that was developed by the IETF in 1999. It is a high- bitrate codec that provides excellent quality speech at a bitrate of 24 kbps. MP4A-LATM is not as widely used as G.729 or OPUS due to its high bitrate requirements.

• Question 78:

  A collaboration engineer must optimize the dial plan within Cisco UCM. There are multiple remote sites. And each site has its own route patterns and local gateways. What should the engineer do on the cisco UCM to optimize the dial plan?

  A. Configure a Standard Local Route Group to use a single route pattern for all calls within the cluster.

  B. Create a centralized dial plan with a Cisco UCM Session Management Edition cluster or a Cisco gatekeeper.

  C. Implement ILS with GDPR so the dial plan can dynamically replicate across clusters.

  D. Leverage Cisco UCM Express as SRST so the phones can have more features of each remote site

  Correct Answer: A
