• Question 45:

  When a call is delivered to a gateway, the calling and called party number must be adapted to the PSTN service requirements of the trunk group. If a call is destined locally, the + sign and the explicit country code must be replaced with a national prefix. For the same city or region, the local area code must be replaced by a local prefix as applicable. Assuming that a Cisco UCM has a SIP trunk to a New York gateway (area code 917), which two combinations of solutions localize the calling and called party for a New York phone user? (Choose two.)

  A. Configure the gateway to translate the calling number and apply it to the dial peer. Combine it with a translation profile for called numbers. ! voice translation-rule 1 rule 1 /^1917/ // rule 2 /^ [+]1917/ // ! voice translation-profile strip+1 translate calling 1 !

  B. Configure two calling party transformation patterns: \+1917.CCCCCC, strip pre-dot, numbering type: subscriber \+!, strip pre-dot, numbering type: national

  C. Configure two called party transformation patterns: \+1917.XXXXXXX, strip pre-dot, numbering type: subscriber \+1.!, strip pre-dot, numbering type: national

  D. Configure the gateway to translate called numbers and apply it to the dial peer. Combine it with a translation profile for calling numbers. ! voice translation-rule 1 rule 1 /^1917!/ // rule 2 /^[+]1917!/ // ! voice translation-profile strip+1 translate called 1 !

  E. Configure two calling party transformation patterns: \+1917.XXXXXXX, strip pre-dot, numbering type: subscriber \+1.!, strip pre-dot, numbering type: national

  Correct Answer: DE

• Question 46:

  Refer to the exhibit. A collaboration engineer adds an analog gateway to a Cisco UCM cluster. The engineer chooses MGCP over SCCP as the gateway protocol.

  

  Which two actions ensure that the gateway registers? (Choose two.)

  A. Delete and re-add the gateway configuration in Cisco UCM.

  B. Enter "mgcp" on the gateway in configuration mode.

  C. Enter "no sccp" on the gateway in configuration mode.

  D. Enter "ccm-manager config" on the gateway in configuration mode.

  E. Enter "ccm-manager mgcp" on the gateway in configuration mode.

  Correct Answer: BE

• Question 47:

  What is the purpose of Mobile and Remote Access (MRA) in the Cisco UCM architecture?

  A. MRA is used to access Webex cloud services only if authenticated with on-premises LDAP service.

  B. MRA is used to make secure PSTN calls by Cisco UCM only while on-premises authentication.

  C. MRA is used to make B2B calls through Expressway registration.

  D. MRA is used to access the collaboration services offered by Cisco UCM from off-premises network connections.

  Correct Answer: D

• Question 48:

  Refer to the exhibit.

  

  An engineer is troubleshooting this video conference issue:

  1.

  A video call between a Cisco 9971 in Region1 and another Cisco 9971 in Region1 works.

  2.

  As soon as the Cisco 9971 in Region1 conferences in a Cisco 8945 in Region2, the Region1 endpoint cannot see the Region2 endpoint video. What is the cause of this issue?

  A. Cisco 8945 does not have a camera connected.

  B. Maximum Audio Bit Rate must be increased.

  C. Maximum Session Bit Rate for Video Calls is too low.

  D. Maximum Session Bit Rate for Immersive Video Calls is too low.

  Correct Answer: C

• Question 49:

  If a phone needs to register with cucm1.cisco.com, which network service assists with the phone registration process?

  A. SMTP

  B. ICMP

  C. DNS

  D. SNMP

  Correct Answer: C

  According to the Cisco Community website1, the phone uses DNS to resolve the hostname of the CUCM server (cucm1.cisco.com) to its IP address. DNS is a network service that translates domain names into IP addresses.

• Question 50:

  What is a characteristic of a SIP endpoint configured in Cisco UCM with "Use Trusted Relay Point" set to "On"?

  B. It enables the Use Trusted Relay Point setting from the associated common device configuration.

  C. If TRP is allocated and MTP is also required for the endpoint, calls fail.

  D. It creates a trust relationship with the called party.
