• Question 64:

  Refer to the exhibit.

  

  All displayed devices are registered to the same Cisco Unified Communications Manager server and the phones are engaged in an active call. Assume that the provided configurations exist at the phone line level and multicast MOH is disabled cluster wide.

  Which description of what will happen when the user of IP phone A presses the Hold soft key is true?

  A. IP phone B receives audio source 2 from MOH server A.
  B. IP phone B receives audio source 3 from MOH server A.
  C. IP phone B receives audio source 2 from MOH server B.
  D. IP phone B receives audio source 3 from MOH server B.
  E. IP phone B receives audio source 1 from MOH server A.
  C. IP phone B receives audio source 2 from MOH server B.

  ---

  Because audio source 2 is in top of the MRGL List and it will be selected locally first.

• Question 65:

  A Cisco Unified Cm user is set up with one remote destination profile that has two remote destination numbers: the first destination number is the user's mobile phone in country A and the second is a mobile phone located in country . All outbound calls are centralized from the gateway at country A. The user reports that inbound calls are properly routed to the mobile phone as long as the user is in country A. But inbound calls are not successfully routed to country B. Which two options could be the cause of this? (Choose two)

  A. The enable mobile connect option must be selected under the user's second remote destination number.
  B. The value of remote destination limits should be chaned to 2 instead of the default value of 4 under the end user page.
  C. The enable mobile voice access option must be selected under the end user page.
  D. The value of maximum wait time for desk pickup should be changed to 20000 instead of the default of D. 10000, under the end user page.
  E. The rerouting calling search space assigned to the user's remote destination profile must have access to international calls.
  A. The enable mobile connect option must be selected under the user's second remote destination number.
  E. The rerouting calling search space assigned to the user's remote destination profile must have access to international calls.

• Question 66:

  Refer to the exhibit.

  

  Which ds0-group option should you select to support automated number identification information collection on inbound calls for this digital T1 voice circuit?

  A. eandm-wink-start
  B. eandm-delay-dial
  C. eandm-delay-dial
  D. eandm-lmr
  E. eandm-fgd
  E. eandm-fgd

  The integrated video conferencing services use the same DSP resources on PVDM3s that are used for widely deployed ISR G2 voice capabilities. These modules, in conjunction with Cisco IOS Software, perform audio and video mixing, video transcoding for certain resolutions, and other functions for video endpoints. PVDM3 modules support flexible media resources and conference profile management to maximize capacity with predictable end-user experiences. Both homogenous and heterogonous video conferences are supported. A homogenous conference refers to one in which participants connect to the ISR G2 with devices that support the same video format attributes (for example, the same codec, resolution, frame rate, and bit rate). A heterogeneous conference refers to one in which participants can connect to a conference bridge with devices that support different video format attributes. Each conference allows 4-, 8-, or 16-party participants.
