• Question 112:

  A user reports that when receiving an inbound call on their IP Phone from the PSTN they are unable to transfer this call to another PSTN number What is the reason for this failure?

  A. The incoming calling search space of the SIP trunk does not include the partition of the line in the IP phone

  B. The gateway is configured with the wrong device pool

  C. The service parameter related to fnet to Offnet Call Transfer is set to TRUE

  D. The IP phone is configured with the wrong region

  Correct Answer: C

• Question 113:

  Refer to the exhibit

  

  A user takes a phone from San Francisco to New York for a short reassignment. The phone was set up to use the San Francisco device pool, and device mobility is enabled on the Cisco UCM. The user makes a call that matches a route pattern in a route list that contains the Standard Local Route Group. To where does the call retreat?

  A. The call egresses in New York because the device automatically is assigned a New York device pool and uses the local gateway

  B. The call egresses in San Francisco because the user uses device mobility and is allowed to roam while still keeping the number and resources assigned in San Francisco

  C. The call fails because the Standard Local Route Group is being used only if no configuration is set for the device pools

  D. The call fails because device mobility is turned on. and the phone is not configured in New York The engineer must configure which sites the device should be roaming to

  Correct Answer: A

  Standard local route group would use San Francisco device pool, if there is no device mobility active Device Mobility Info Configuration delivers by IPv4 Subnet a selected Device Pool ; in this case new york device pool and its local gateway in new york

• Question 116:

  What is required when deploying co-resident VMs by using Cisco UCM?

  A. Provide a guaranteed bandwidth of 10 Mbps.

  B. Ensure that applications will perform QoS.

  C. Avoid hardware oversubscription.

  D. Deploy the VMs to a server running Cisco UCM.

  Correct Answer: C

  When deploying co-resident VMs by using Cisco UCM, it is important to avoid hardware oversubscription. This means that you should not assign more resources to the VMs than the physical hardware can provide. For example, if you have a

  server with 16 CPU cores, you should not assign more than 16 CPU cores to the VMs. If you oversubscribe the hardware, the VMs will not be able to get the resources they need to run properly. This can lead to performance problems and

  even outages. To avoid hardware oversubscription, you should carefully plan your VM deployments. You should also monitor the performance of the VMs to make sure that they are not overusing the resources.

  Here are some additional tips for deploying co-resident VMs by using Cisco UCM:

  Use a virtualization platform that supports Cisco UCM. Make sure that the VMs have the correct operating system and software installed. Configure the VMs to use the correct network settings. Monitor the performance of the VMs to make

  sure that they are running properly.
