• Question 374:

  Refer to the exhibit.

  

  Which two statements about calls that match dial-peer voice 7 voip are true? (Choose two.)

  A. All calls that match dial-peer voice 7 use G.711.
  B. All calls that match dial-peer voice 7 have the Diversion header removed from SIP Invites.
  C. All calls that match dial-peer voice 7 use NOTIFY-based, out-of-band DTMF relay.
  D. All calls that match dial-peer voice 7 are marked with DSCP 32.
  E. All calls that match dial-peer voice 7 are marked with DSCP 34.
  B. All calls that match dial-peer voice 7 have the Diversion header removed from SIP Invites.
  E. All calls that match dial-peer voice 7 are marked with DSCP 34.

  Dial peer 7 refers to SIP profile 102, which we can see is configured to have the Diversion header removed from SIP Invites. Dial peer 7 marks traffic with AF41, which is equivalent to DSCP 34.

• Question 375:

  Which Cisco Unified Contact Center Express core system software component communicates with Cisco Agent Desktop for agent state control and call control?

  A. Unified CCX Engine
  B. Database
  C. Monitoring
  D. Recording
  E. RmCm
  A. Unified CCX Engine

  ---

  The Unified CCX Engine enables you to run multiple applications to handle Unified CM Telephony calls or HTTP requests. The Unified CCX Engine uses the Unified CM Telephony subsystem to request and receive services from the

  Computer Telephony Interface (CTI) manager that controls Unified CM clusters. The Unified CCX Engine is implemented as a service that supports multiple applications. You can use a web browser to administer the Unified CCX Engine and

  your Unified CCX applications from any computer on the network. Unified CCX provides you the following two web interfaces:

  Unified CCX Administration web interface: Used to configure system parameters, subsystems, view real-time reports that include total system activity and application statistics, and so on.

  Unified CCX Serviceability web interface: Used to view alarm and trace definitions for Unified CCX services, start and stop the Unified CCX Engine, monitor Unified CCX Engine activity, and so on.

• Question 376:

  Which two statements about virtual SNR in Cisco Unified Communications Manager Express are true? (Choose two.)

  A. The SNR DN must be configured as SCCP.
  B. Calls cannot be pulled back from the phone associated with the DN.
  C. Ephone hunt groups are supported.
  D. The virtual SNR DN must be assigned to an ephone.
  E. Music on hold is supported for trunk and line side calls.
  A. The SNR DN must be configured as SCCP.
  B. Calls cannot be pulled back from the phone associated with the DN.

  ---

  To configure a virtual SNR DN on Cisco Unified SCCP IP phones, perform the following steps: Prerequisites

  Cisco Unified CME 9.0 or a later version.

  Restrictions

  Virtual SNR DN only supports Cisco Unified SCCP IP phone DNs.

  

  Virtual SNR DN provides no mid-call support.

  

  Mid-calls are either of the following:

  ?Calls that arrive before the DN is associated with a registered phone and is still present after the DN is associated with the phone.

  ?Calls that arrive for a registered DN that changes state from registered to virtual and back to registered.

  Mid-calls cannot be pulled back, answered, or terminated from the phone associated with the DN.

  

  State of the virtual DN transitions from ringing to hold or remains on hold as a registered DN.

• Question 377:

  Which statement describes a video conference viewing mode on a Cisco Integrated Router Generation 2 with packet voice and video digital signal processor 3 that is configured to work with Cisco Unified Communications Manager?

  A. Video of one participant is displayed to all other video capable participants in a round-robin manner.
  B. Video of the loudest speaker is displayed across all video capable participants.
  C. Video of one participant, except for those with mute enabled, is displayed to all other video capable participants in a round-robin manner.
  D. The dedicated conference lecturer can one participant at a time, while all others can only see the lecturer.
  E. Video of one participant is displayed to all other video capable participants in a random manner using an algorithm hard-coded in Cisco IOS.
  B. Video of the loudest speaker is displayed across all video capable participants.

• Question 378:

  The number of calls waiting in a Cisco Unified Communications Manager native call queue has reached its maximum limit.

  Which statement about what happens to additional incoming calls is true?

  A. Calls are handled according to the Forward Hunt Busy settings on the Hunt Pilot configuration page.
  B. Calls are handled according to the Forward Hunt No Answer settings on the Hunt Pilot configuration page.
  C. Calls are handled according to the Forward Hunt Busy settings on the Line Group members.
  D. Calls are handled according to the Hunt Options settings on the Line Group Configuration page.
  E. Calls are handled according to the When Queue Is Full settings on the Hunt Pilot Configuration page.
  E. Calls are handled according to the When Queue Is Full settings on the Hunt Pilot Configuration page.

  ---

  There are three main scenarios where alternate numbers are used: When queue is full When maximum wait time is met When no hunt members are logged in or registered

  When queue is full Call Queuing allows up to 100 callers to be queued per hunt pilot (the maximum number of callers allowed in queue on a hunt pilot page). Once this limit for new callers been reached on a particular hunt pilot, subsequent calls can be routed to an alternate number. This alternate number can be configured through the Hunt Pilot configuration page (through the "Destination When Queue is Full" settings). When maximum wait time is met Each caller can be queued for up to 3600 seconds per hunt pilot (the maximum wait time in queue). Once this limit is reached, that caller is routed to an alternate number. This alternate number can be configured through the Hunt Pilot configuration page (through the "Maximum wait time in queue" settings). When no hunt members are logged in or registered In a scenario where none of the members of the hunt pilot are available or registered at the time of the call, hunt pilot configuration provides an alternate number field (through the "When no hunt members are logged in or registered" settings) where calls can be routed. For Call Queuing, a hunt pilot member is considered available if that member has both deactivated do not disturb (DND) and logged into the hunt group. In all other cases, the line member is considered unavailable or logged off.

  B. Set CDR Enabled Flag to True and set Call Diagnostics Enabled to Enable Regardless of CDR Enabled Flag.
  C. Set CDR Log Calls with Zero Duration Flag to True.
  D. Set CDR Enabled Flag to True.

  A. 6
  B. 7
  C. 8
