Refer to the exhibit.

 

 

 

clip_image002

 

The exhibit shows the output of debug isdn q931. An inbound PSTN call was received by a SIP gateway that is reachable via a SIP trunk that is configured in Cisco Unified Communications Manager. The call failed to ring extension 3001. If the phone at extension 3001 is registered and reachable through the gateway inbound CSS, which three actions can resolve this issue? (Choose three.)

 

A.

Change the significant digits for inbound calls to 4 on the SIP trunk configuration in Cisco Unified Communications Manager.

B.

Configure the digit strip 4 on the SIP trunk under Incoming Called Party Settings in Cisco Unified Communications Manager.

C.

Configure a translation pattern in Cisco Unified Communications Manager that can be accessed by the trunk CSS to truncate the called number to four digits.

D.

Configure a called-party transformation CSS on the gateway in Cisco Unified Communications Manager that includes a pattern that transforms the number from ten digits tofour digits.

E.

Configure a voice translation profile in the SIP Cisco IOS gateway with a voice translation rule that truncates the number from ten digits to four digits.

F.

Configure the Cisco IOS command num-exp 2288223001 3001 on the gateway ISDN interface.

 

Answer: ACE

 

 

QUESTION 4  (Topic 1)

 

Refer to the exhibit.

 

 

 

clip_image003

 

An engineer is troubleshooting an outbound call and needs to see each step of the dial plan as it is being parsed in the system. The engineer is not able to see all of the steps in the trace output. How can this problem be resolved?

 

A.

Change the SDL Trace Flush Immediately to True.

B.

No change is needed; the steps are automatically shown in trace files.

C.

Change the SDL TraceType Flag to 0x9000EC44

D.

Change the SDL Trace Max File Size to a higher number because it is not large enough to display dial plan steps.

E.

Change the Digit Analysis Complexity toTranslationAndAlternatePatternAnalysis.

 

Answer: E

Explanation: Explanation-DIGIT ANALYSY COMPLEXITY

determines whether detailed digit analysis information is included in the trace output and Cisco DNA. If you want to see translation pattern and alternative pattern match information, set this parameter to TranslationAndAlternatePatternAnalysis. The default is StandardAnalysis, which does not show pattern transformations. To troubleshoot dial plan issues, change to Translational Pattern and Alternate Analysis. Setting this option creates detailed digit analysis in CCM traces.

QUESTION 6  (Topic 1)

 

Refer to the exhibit.

 

 

 

clip_image006

 

When a call is placed to extension 3001, the associated remote destination 907700990255 does not ring. Which CSS is responsible for extending the call to the remote destination?

 

A.

The Calling Search Space is responsible.

B.

The Rerouting Calling Search Space is responsible

C.

The Calling Party Transformation CSS is responsible

D.

The Calling Search Space and the Rerouting Calling Search Space are concatenated to determine where the call should be extended

 

Answer: B

 

 

QUESTION 7  (Topic 1)

 

How does LLQ ensure that voice traffic is always expedited?

 

A.

LLQ adds a strict priority class to CBWQF. The class allows delay-sensitive data such as voice to be dequeued and sent first.

B.

LLQ uses CBWFQ to prioritize voice traffic and dequeue the voice packets so that they can be handled first.

C.

The strict priority queue has a higher weight than the queues in CBWFQ. This weight allows the delay sensitive data such as voice to be dequeued and sent first.

D.

The LLQ strict priority queue allows delay-sensitive data such as voice to be dequeued and sent first (before packets in order queue are dequeued), giving delay sensitive data preferential treatment over other traffic.

QUESTION 8  (Topic 1)

 

The CLI utils dbreplication reset all was run on a Cisco Unified Communications Manager. However, replication failed to restart. Which course of action should be taken to resolve this issue?

 

A.

Restart the replication from the Cisco Unified Communications Manager RTMT tool.

B.

Issue the CLI command utils dbreplication runtimestate

C.

Issue the CLI command utils dbreplication reset

D.

Issue the CLI command utils dbreplication clusterreset

E.

Issue the CLI command utils dbreplication clusterreset all

 

Answer: D

Explanation:I’ve found only this post:

Database Replication Does Not Occur When Connectivity Is Restored on Lost Node Symptom Database replication does not occur when connectivity is restored on lost node recovery. You can verify the state of replication by using the methods given in the topic Replication Fails Between the Publisher and the Subscriber. Only use the following procedure if you have already tried to reset replication on the node, and have been unsuccessful.

Possible Cause: The CDR check remains stuck in a loop, due to a delete on device table.

Recommended Action

 

Step1 Run utils dbreplication stop on the affected subscribers. You can run them all at once.

 

Step2 Wait until Step1completes, then, run utils dbreplication stop on the affected publisher server.

 

Step3 Run utils dbreplication clusterreset from the affected publisher server. When you run the command, the log name gets listed in the log file. Watch this file to monitor the process status. The path to the follows:/var/log/active/cm/trace/dbl/sdi

 

 

 

Step4 From the affected publisher, runutils dbreplication reset all.

 

Step5 Stop and restart all the services on all the subscriber servers [or restart/reboot all the systems(subscriber servers)] in the cluster to get the service changes. Do this only afterutils dbreplication status shows Status 2.

QUESTION 9  (Topic 1)

 

Refer to the exhibit.

 

clip_image007

 

HQ_MPQL is assigned to the HQ IP phones. BR_MRPGL is assigned to the BR IP phones. The remote site BR IP phones only support G711 codec. When a call is placed from HQ phone, the call fails. Which statement indicates how this issue is resolved?

 

A.

Configure the Transcoder at the HQ site and assign it to HQ_MRG

B.

Configure the Transcoder at the BR
site and assign it to BR_MRG

C.

The Transcoder should be assigned to its own MRG, which should then be assigned to the default device pool at HQ.

D.

A Transcoder is not needed. The HQ phones will automatically change over to G 711 codec.

 

Answer: B

Explanation:The phone in BR ony support G711. The region configuration only allow G729 for HQ to BR. So you need a transcoder in BR.
