Question 1:
A customer wants to conduct B2B video calls with a partner using an on-premises conferencing solution. Which two devices are needed to facilitate this request? (Choose two.)
A. Expressway-C
B. MGCP gateway
C. Cisco Unified Border Element
D. Cisco TelePresence Management Suite
E. Expressway-E
Correct Answer: AE
Question 2:
An administrator is asked to implement toll fraud prevention in Cisco UCM, specifically to restrict off- net to off-net call transfers How is this implemented?
A. Implement time-of-day routing.
B. Use the correct route filters.
C. Set the appropriate service parameter
D. Enforce ad-hoc conference restrictions
Correct Answer: C
To restrict off-net to off-net call transfers, an administrator can set the “Block Offnet to Offnet Transfer” service parameter to “On”. This will prevent users from transferring calls from one external number to another external number.
The other options are not correct because:
Enforce ad-hoc conference restrictions: This will prevent users from creating ad- hoc conferences, but it will not prevent them from transferring calls.
Implement time-of-day routing: This will allow calls to be routed to different destinations based on the time of day, but it will not prevent users from transferring calls.
Use the correct route filters: This will allow calls to be filtered based on the destination, but it will not prevent users from transferring calls.
Question 3:
Refer to the exhibit.
An administrator configures a secure SIP trunk on Cisco UCM. Which value is needed in the Secure Certificate Subject or Subject Alternate Name field to accomplish this task?
A. the common name of the remote device certificates
B. the fully qualified domain name of all Cisco UCM nodes that run the CallManager service
C. the common name of the Cisco UCM CallManager certificate
D. the fully qualified domain name of the remote device that is configured on the SIP trunk
Correct Answer: D

Question 4:
Refer to the exhibit.
Cisco Unified Border Element is attempting to establish a call with Subscriber 1, but the call fails. Cisco Unified Border Element then retries the same call with Subscriber 2, and the call proceeds normally. Which action resolves the issue?
A. Verify that the Run On All Active Unified CM Nodes checkbox is enabled.
B. Verify that the correct calling search space is selected for the Inbound Calls section.
C. Verify that the Significant Digits field for Inbound Calls is set to All.
D. Verify that the PSTN Access checkbox is enabled.
Correct Answer: A
503 – Service Unavailable – The server\’s SIP service is temporarily unavailable. If CSS is missing it would not find a proper DN, and will return <404 – not found<
Since there is no answer of several Trunks, it only explains one trunk and >Run On All Unified CM Nodes< should put in concern
Question 5:
What are two Cisco UCM location bandwidths that are deducted when G.729 and G.711 codecs are used? (Choose two.)
A. If a call uses G.729, Cisco UCM subtracts 16k
B. If a call uses G.711, Cisco UCM subtracts 80k
C. If a call uses G.729, Cisco UCM subtracts 24k
D. If a call uses G.711, Cisco UCM subtracts 64k
E. If a call uses G.729, Cisco UCM subtracts 40k
Correct Answer: BC
After the call is established, the Cisco Unified Communications Manager will subtract bandwidth from the locations, depending on the codec that is used in that call. If the call is using G.711, Cisco Unified Communications Manager subtracts
80k. If the call is using G.723, Cisco Unified Communications Manager subtracts 24k. If the call is using G.729, Cisco Unified Communications Manager subtracts 24k.

Question 6:
Refer to the exhibit.
An engineer configured NTP on Cisco UCM and runs the utils ntp status command from Cisco UCM CLI and receives an error message. How is this issue mitigated and fixed?
A. Use an external NTP server and allow communication on port 53.
B. Ensure that Cisco UCM can communicate with the NTP server on port 53 and have a Windows NTP server configured with NTPv3.
C. configure the NTP server to answer requests on port 443.
D. Ensure that Cisco UCM can communicate with the NTP server on port 123 and have a Linux NTP server configured with NTPv4.
Correct Answer: D

Question 7:
An end user at a remote site is trying to initiate an Ad Hoc conference call to an end user at the main site. The conference receives an error message on the phone: Cannot complete conference call. What is the cause of the issue?
A. The transcoder resource Is missing.
B. The remote phone does not have the conference feature assigned
C. A software conference bridge is not assigned.
D. A Media Termination Point is missing.
Correct Answer: A
Question 8:
An administrator would like to set several Cisco Jabber configuration parameters to only apply to mobile clients (iOS and Android). How does the administrator accomplish this with Cisco Jabber 12.9 and Cisco UCM 12.5?
A. Assign the desired configuration file to “Mobile” Jabber Client Configuration in the Service Profile.
B. Deploy jabber-config-user.xml on iOS and Android devices.
C. Upload the jabber-config.enc file to TFTP
D. Create a user profile in Jabber Policies.
Correct Answer: A
Question 9:
An administrator uses the Cisco Unified Real-Time Monitoring Tool to investigate recent calls on a Cisco UCM cluster. The SIP trace for an on-net, direct-media call shows two 180 Ringing and two 11 BYE messages. Why are there multiples of each message type in the trace?
A. The source phone sends a 180 Ringing signal to the Cisco UCM, which sends a 180 Ringing signal to the destination phone. The same process applies to 11 BYE messages.
B. The source phone must signal to the destination phone that it is ringing, and the destination phone signals back with a 180 Ringing message. The same process applies to 11 BYE messages.
C. The destination phone signals back to the Cisco UCM that it is ringing, and the Cisco UCM signals back to the source phone.
D. The calls have an MTP in the call path due to different codec support. The calls are subsequently split into two call legs.
Correct Answer: A
Question 10:
Which configuration on Cisco Unified Communications Manager is required for SIP MWI to work?
A. The line partition must be inside the inbound CSS assigned to the CUC SIP trunk.
B. The line partition must be inside the rerouting CSS assigned to the Cisco Unity Connection SIP trunk.
C. Set the “Enable message waiting indicator” on the part group.
D. Assign a MWI extension on the mailbox.
Correct Answer: A
The line partition must be inside the inbound CSS assigned to the CUC SIP trunk. This ensures that the SIP MWI messages are sent to the correct destination.
The other options are incorrect because:
Assigning an MWI extension on the mailbox is not required for SIP MWI to work. The line partition does not need to be inside the rerouting CSS assigned to the Cisco Unity Connection SIP trunk.
Setting the “Enable message waiting indicator” on the port group is not required for SIP MWI to work.
Question 11:
Due to service provider restriction, Cisco Unified Communications Manager cannot send video in the SDP. Which two options on Cisco Unified CM are configured to suppress video in the SDP is outgoing invites? (Choose two.)
A. Check the Send send-receive SDP in mid-call INVITE check box on the SIP trunk SIP profile.
B. Add the audio forced command to voice service voip on the Unified Border Elements.
C. Check the Retry Call as Audio on the SIP trunk
D. Set Video bandwidth in the Region settings to 0.
E. Change the Video Capabilities dropdown on the endpoint to Disabled.
Correct Answer: CD
The reason is it has to be only in CUCM per the question. You would create a specific Region relationship for the Device Pool applied to the trunk that cannot handle video and thus change the Maximum Video Bandwidth to 0 while setting retry a video call as audio on the Phone Configuration (default setting is this is already checked).
Question 12:
Given the H.323 gateway configuration and using Cisco best practices, how must the called party transformation pattern be configured to ensure that a proper ISDN type of number is set?
A. Option A
B. Option B
C. Option C
D. Option D
Correct Answer: A
