• Question 395:

  When IP phone A was provisioned in a Cisco Unified Communications Manager, 2001 was configured as the directory number for its first line. Also, [email protected] was defined as the only directory URI on the Directory Number configuration page for this line. A few days later, an end user was created in the same Cisco Unified Communications Manager and was associated with the same phone with the primary extension set to 2001. Also, [email protected] was defined as a directory URI for that end user.

  Which option about the primary directory URI for IP phone A is true?

  A. [email protected]
  B. [email protected]
  C. It depends on which radio button was selected next to the Directory URI entries on the Directory Configuration page.

• Question 396:

  Which statement about system broadcast messages in Cisco Unity Connection is true?

  A. The user can skip a system broadcast message to listen to new messages first.
  B. The user can forward a system broadcast message only if it has been played in its entirety.
  C. System broadcast messages are synchronized between Cisco Unity Connection and Exchange when Single Inbox is configured.
  D. System broadcast messages do not trigger MWI.
  E. System broadcast messages are played immediately after users sign in and listen to message counts for new and saved messages.
  D. System broadcast messages do not trigger MWI.

  ---

  System broadcast messages are played immediately after users log on to Cisco Unity Connection by phone even before they hear message counts for new and saved messages. After logging on, users hear how many system broadcast messages they have and Connection begins playing them.

• Question 397:

  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. Assuming the provided configurations exist at the phone line level and multicast MOH is disabled clusterwide, what will happen when the user of IP Phone A presses the Transfer softkey?

  A. The IP Phone B user hears audio source 3 from MOH Server A.
  B. The IP Phone B user hears audio source 4 from MOH Server B.
  C. The IP Phone B user hears audio source 3 from MOH Server B.
  D. The IP Phone B user hears audio source 2 from MOH Server B.
  E. The IP Phone A user hears no on-hold music.
  C. The IP Phone B user hears audio source 3 from MOH Server B.

  Held parties determine the media resource group list that a Cisco Unified Communications Manager uses to allocate a music on hold resource.

• Question 398:

  Which statement about the Cisco UC on UCS TRC and the third-party server specs-based virtualization support model is true?

  A. Both the UC on UCS TRC and the third-party servers spec-based support models have rule-based approaches.
  B. The UC on UCS TRC support model has a rule-based approach and the third-party servers spec-based support model has a configuration-based approach.
  C. The UC on UCS TRC support model requires a high level of virtualization experience while the third-party server spec-based support model requires a low to medium level virtualization experience.
  D. VMware vCenter is mandatory for the UC on UCS TRC support model but it is optional for the third-party server spec-based support model.
  E. VMware vCenter is optional for the UC on UCS TRC support model but it is mandatory for the third-party server spec-based support model.
  E. VMware vCenter is optional for the UC on UCS TRC support model but it is mandatory for the third-party server spec-based support model.

  VMware vCenter is

  optional when deploying on UC on UCS Tested Reference Configuration hardware

  mandatory when deploying on UC on UCS Specs-based and Third-party Server Specs-based hardware.

  vCenter Statistics Level 4 logging is mandatory so that Cisco TAC is able to provide effective support.

  Click here for how to configure VMware vCenter to capture these logs. If not configured by default, Cisco TAC may request enabling these settings in order to provide effective support.

  Also note that enablement of specific VMware vSphere management features may require vCenter and/or a higher feature Edition of vSphere ESXi.

  Cisco Collaboration does not require its own dedicated vCenter.

  Note that when VMware vCenter is not required and is not used, then VMware vSphere ESXi's default management interface is its free/included VMware vSphere Client (formerly branded VI Client).
