Cisco 400-051 Online Questions & Answers

• Question 441:

  What does a weight represent in the Enhanced Location Call Admission Control mechanism on Cisco Unified Communications Manager?

  A. It defines the bandwidth that is available between locations.
  B. It defines the bandwidth that is available on a link.
  C. It is the amount of bandwidth allocation for different types of traffic.
  D. It is used to provide the relative priority of a link between locations.
  E. It is used to provide the relative priority of a location.
  D. It is used to provide the relative priority of a link between locations.

  ---

  A weight provides the relative priority of a link in forming the effective path between any pair of locations. The effective path is the path used by Unified CM for the bandwidth calculations, and it has the least cumulative weight of all possible paths. Weights are used on links to provide a "cost" for the "effective path" and are pertinent only when there is more than one path between any two locations.

• Question 442:

  Which of the following Cisco IOS-XE dial-peer commands has the highest preference for outbound SIP dial-peer selection?

  A. Destination uri
  B. Destination uri-diversion
  C. Destination calling e164-pattern-map
  D. Destination-pattern
  E. Carrier-id target
  F. Destination e164-pattern-map
  C. Destination calling e164-pattern-map

• Question 443:

  Which protocol is used by presence-enabled users in Cisco IM and Presence to control phones that are registered to Cisco Unified Communications Manager?

  A. AXL/SOAP
  B. CTI/QBE
  C. SIP/SIMPLE
  D. LDAP
  E. XMPP
  B. CTI/QBE

  ---

  The CTI gateway provides desk phone control when users are configured for phone association mode. Proper installation calls upon information to specify CTI gateway server names, addresses, ports, and protocols on CUPS. Configured correctly, the CTI gateway enables users logging in to CUPC to reach the CTI gateway.

• Question 444:

  Which two settings must be the same between the backup source and restore target with DRS in Cisco Unified Communications Manager? (Choose two.)

  A. Server Hostname
  B. Server IP Address
  C. Cluster Security Password
  D. NTP Servers
  E. Domain Name
  F. Certificate Information
  A. Server Hostname
  B. Server IP Address

• Question 445:

  A collaboration engineer is designing an Cisco IMandP implementation to support instant messaging logging for compliance. Which two external databases can be used to support that functionality? (Choose two.)

  A. Oracle database
  B. MySQL database
  C. Microsoft SQL database

  Refer to the exhibit.

  

  Assume there are no classes of service restrictions and all numbers shown are reachable from this Cisco Unified IP 7965 Phone. Which statement about the dialing key strokes that allow the owner of this phone to reach directory number 2000 is true?

  A. Press the last button on the right hand side of the phone screen.
  B. There is no way to speed dial to directory number 2000 because the speed dial entry is not assigned.
  C. Press 7 on the phone keypad, followed by the Dial softkey.
  D. Press 6 on the phone keypad, followed by the Dial softkey.
  E. Press 5 on the phone keypad, followed by the AbbrDial softkey.
  E. Press 5 on the phone keypad, followed by the AbbrDial softkey.

• Question 447:

  Which two guidelines are recommended when configuring agent phones for Cisco Unified CCX agents? (Choose two.)

  A. In the Multiple Call/Call Waiting Settings section, set the Maximum Number of Calls to 2.
  B. In the Multiple Call/Call Waiting Settings section, set the Busy Trigger value to 2.
  C. The Unified CCX extension for the agent must be listed within the top four extensions on the device profile.
  D. In the Multiple Call/Call Waiting Settings section, set the Maximum Number of Calls to at least 3.
  E. Always enable SRTP when configuring an agent phone.
  A. In the Multiple Call/Call Waiting Settings section, set the Maximum Number of Calls to 2.
  C. The Unified CCX extension for the agent must be listed within the top four extensions on the device profile.

  Follow these guidelines when configuring agent phones for Unified CCX agents:

  Choose Device > Phone in Unified Communications Manager Administration. The Find and List Phones window is displayed.

  Enter search criteria to locate a specific phone and click Find. A list of phones that match the search criteria is displayed. Click the device name of the phone to which you want to add a directory number. The Phone Configuration window is

  displayed.

  In the Unified Communications Manager Administration Phone Configuration web page, select the required Association Information (on the left) to get to the Directory Number Configuration web page. On this page, make the following

  changes:

  -

  In the Multiple Call/Call Waiting Settings section, set the Maximum Number of Calls to 2 (default is 4) for Cisco Unified IP Phones 7900 Series and 3 for Cisco Unified IP Phones 8961, 9951, and 9971.

  -

  In the Multiple Call/Call Waiting Settings section, set the Busy Trigger value to 1 (default is 2).

  -

  In the Call Forward and Call Pickup Settings section, verify that you do not forward any Unified Communications Manager device to the Unified CCX extension of an agent.

  -

  In the Call Forward and Call Pickup Settings section, verify that you do not configure the Unified CCX extension of an agent to forward to a Unified CCX route point. Always disable (turn off) Secure Real-Time Transport Protocol (SRTP)

  when configuring a Cisco Unified Communications product. You can disable SRTP for a specified device or for the entire Unified Communications Manager:

  -

  For a specified device--Choose Device > Phone. In the Find and List Phone page, select the required phone device. In the Phone Configuration page for the selected phone, scroll down to the Protocol Specific Information section. To turn off

  SRTP on the phone device, select any one of the Non Secure SCCP Profile auth by choices from the drop-down list in SCCP Phone Security Profile or SCCP Device Security Profile field.

  -

  For the entire Unified Communications Manager cluster -- Choose System > Enterprise Parameters. In the Enterprise Parameters Configuration page, scroll down to the Securities Parameters section, to verify that the corresponding value

  for the Cluster Security Mode field is 0. This parameter indicates the security mode of the cluster. A value of 0 indicates that phones will register in nonsecure mode (no security). The Unified CCX extension for the agent must be listed within

  the top 4 extensions on the device profile. Listing the extension from position 5 on will cause Unified CCX to fail to monitor the device, so the agent will not be able to log in.

  Do not forward any Unified Communications Manager device to the Unified CCX extension of an agent.

  Do not configure the Unified CCX extension of an agent to forward to a Unified CCX route point.

  Do not use characters other than the numerals 0 to 9 in the Unified CCX extension of an agent.

  Do not configure two lines on an agent phone with the same extension when both lines exist in different partitions.

  Do not assign a Unified CCX extension to multiple devices.

  Do not configure the same Unified CCX extension in more than one device or device profile. (Configuring a Unified CCX extension in one device or device profile is supported.)

  To use Cisco Unified IP Phones 9900 Series, 8900 Series, and 6900 Series as agent devices, the RmCm application user in Unified Communications Manager needs to have "Allow device with connected transfer/conference" option assigned

  to itself.

  B. Rack: 100rel
  C. Allow: PRACK
  D. Require: 100rel
  E. Supported: 100rel
  C. Allow: PRACK

• Question 449:

  Which three statements about configuring partitioned intradomain federation to Lync are true? (Choose three.)

  B. IMandP and Lync should federate to any required remote domains.
  C. You must update the URIs of any users migrated from Lync to IMandP to match the Cisco Unified Presence Server SIP URI format.
  D. A static route must be added to point the local presence domain to the Lync server.
  E. Microsoft RCC must be enabled.
  F. The Enable use of Email Address when Federating option can be turned on if SIP URIs are different between IMandP and Lync.
  A. Intradomain federation to Lync is only possible using SIP.
  C. You must update the URIs of any users migrated from Lync to IMandP to match the Cisco Unified Presence Server SIP URI format.
  D. A static route must be added to point the local presence domain to the Lync server.
