• Question 232:

  A collaboration engineer configures Global Dial Plan Replication for multiple Cisco UCM clusters. The local cluster acts as the hub cluster, and the remaining clusters act as spoke clusters. Which service must the engineer configure on the local cluster?

  A. Location Conveyance on intercluster SIP trunks

  B. Intercluster Lookup Service

  C. Intra-Cluster Communication Signaling

  D. Mobility Cross Cluster

  Correct Answer: B

  Use global dial plan replication to create a global dial plan that spans across the Intercluster Lookup Service (ILS) network. When you enable Global DialPlan Replication, you configure the dial plan component on one cluster, and ILS replicates that information throughout the ILS network. Use global dial plan replication to create a global dial plan that spans across the Intercluster Lookup Service (ILS) network.

• Question 233:

  Refer to the exhibit.

  

  An administrator is attempting to register a SIP phone to a Cisco UCM but the registration is failing. The IP address of the SIP Phone is 10.117.34 222 and the IP 1 address of the Cisco UCM is 10.0.101.10. Pings from the SIP phone to the Cisco UCM are successful. What is the cause of this issue and how should it be resolved?

  A. The certificates on the SIP phone are not trusted by the Cisco UCM. The SIP phone must generate new certificates.

  B. DNS lookup for the Cisco UCM FQDN is failing. The SIP phone must be reconfigured with the proper DNS server.

  C. An NTP mismatch is preventing connection of the TCP session between the SIP phone and the Cisco UCM. The SIP phone and Cisco UCM must be set with identical NTP sources.

  D. An network device is blocking TCP port 5060 from the SIP phone to the Cisco UCM. This device must be reconfigured to allow traffic from the IP phone.

  Correct Answer: D

• Question 234:

  An engineer troubleshoots a Cisco Jabber login problem on a Windows PC in the corporate network. The login fails with the error message "Cannot find your services automatically. Click advanced settings to set up manually.'' Which action should the engineer take first?

  A. Verify the username and password and try again

  B. Verify whether the cup-xmpp certificates are valid.

  C. Perform a manual DNS lookup of SRV record _collab-edge._tls.domain.com.

  D. Perform a manual DNS lookup of SRV record _cisco-uds.tcp.domain.com.

  Correct Answer: D

• Question 235:

  Which datastore and protocol is used for saving back-up files within the Disaster Recovery System of Cisco UCM?

  A. remote disk on a CIFS share

  B. remote disk on the SFTP server

  C. local disk on the Cisco UCM server

  D. remote disk on an NFS share

  Correct Answer: B

  -A user interface for performing backup and restore tasks;

  -A distributed system architecture for performing backup and restore functions, including monitoring the current backup status and providing a history log;

  -Scheduled or manual backups;

  -Backups archived to a physical drive or remote SFTP server;

• Question 236:

  A. maximum sessions hardware 50

  B. video codec h264

  C. codec pass-through

  D. associate application Cisco Unified Border Element

• Question 237:

  Refer to the exhibit.

  

  Calls to Cisco Unity Connection are failing across Cisco Unified Border Element when callers try to select a menu prompt Why is this happening and how is it fixed?

  A. Cisco Unified Border Element is not sending any support for DTMF. DTMF configuration must be added to the appropriate dial peer.

  B. The Cisco Unity Connection Call Handler is configured for a -Release to Switch" transfer type. Transfers must be disabled for the Cisco Unity Connection Call Handler.

  C. Cisco Unity Connection is configured on G.729 only. Cisco Unity Connection must be reconfigured to support iLBC.

  D. Cisco Unified Border Element is sending the incorrect media IP address. The IP address of the loopback interface must be advertised in the SDP.

  Correct Answer: A

  m = audio 35904 RTP/AVP 8 101 a = rtpmap:8 PCMA/8000 a = rtpmap:101 telephone-event/8000

  101 being the DTMF attribute ETC

• Question 238:

  Refer to the exhibit.

  

  Which outgoing m-line SDP is sent to Cisco UCM after matching the appropriate dial peers via Cisco Unified Border Element?

  A. m=audio 16550 RTP/AVP 0 8 18 a=rtpmap:0 PCMU/8000/1 a=rtpmap:8 PCMA/8000/1 a=rtpmap:18 G729/8000/1

  B. m=audio 16550 RTP/AVP 18 0 a=rtpmap:0 PCMU/8000/1 a=rtpmap:18 G729/8000/1

  C. m=audio 16550 RTP/AVP 8 0 18 a=rtpmap:0 PCMU/8000/1 a=rtpmap:8 PCMA/8000/1 a=rtpmap:18 G729/8000/1

  D. m=audio 16550 RTP/AVP 18 0 a=rtpmap:8 PCMA/8000/1 a=rtpmap:0 PCMU/8000/1 a=rtpmap:18 G729/8000/1

  Correct Answer: B

  it compares with the invite before sending to CUCM leaving G.711ulaw and G.729 remaining. For some reason the order is messed up but it seems like the best answer still.
