• Question 93:

  What is the most important consideration when designing a QoS voice framework?

  A. bandwidth calculations
  B. codec selection
  C. speed propagation
  D. Layer 2 overhead consumption
  B. codec selection

• Question 94:

  A company deploys centralized cisco ucm architecture for a hub location and two remote sites.

  1. The company has only one ITSP connection at the hub connection, and ITSP supports only G.711 calls

  2. Remote site A has a 1-Gbps fiber connection to the hub connection and calls to and from remote side A use G.711 codec

  3. Remote site B has a 1 T1 connection to the hub location and calls to and from remote site B use G.729 codec Based on the provided guidance, a Cisco voice engineer must design media resource management for the customer.

  What is the method that needs to be followed?

  A. configure the hardware transcoder on the site B router.
  B. configure the hardware transcoder on the site A router.
  C. configure the hardware transcoder on the hub location router.
  D. configure the software transcoder on Cisco UCM to support voice calls to and from both remote sites.
  C. configure the hardware transcoder on the hub location router.

  ---

  Explanation

  Site B has a T1 connection and we don't want to force them to limit the number of calls. As an administrator, i would take the incoming calls from site B in G729 and do a transcode at the hub location, and receive an Incoming call to Site B in G 711 and transcode it to G729 and traverse over T1. Win Win situation.

• Question 95:

  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.
  C. Avoid hardware oversubscription.

  ---

  Explanation

  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.

• Question 98:

  Which action is required for a firewall configuration on a Mobile and Remote Access through Cisco Expressway deployment?

  A. The external firewall must allow these inbound connections to Expressway: SIP: TCP 5061: HTTPS: TCP 8443; XMPP: TCP 5222; Media: UDP 36002 to 59999.
  B. The internal firewall must allow these inbound and outbound connections between Expressway-and Expressway-E: SIP: HTTPS (tunneled over SSH between and E): TCP 2222: TCP 7001; Traversal Media: UDP 2776 to 2777 (or 36000 to 36011 for large VM/appliance); XMPP: TCP 7400.
  C. Do not use a shared address for Expressway-E and Expressway-, as the firewall cannot distinguish between them. If static NAT for IP addressing on Expressway-E is used, ensure that any NAT operation on Expressway-does not resolve the same traffic IP address. Shared NAT is not supported.
  D. The traversal zone on Expressway-points to Expressway-E through the peer address field on the traversal zone, which specifies the Expressway-E server address. For dual NIC deployments, set the Expressway-E address using an FQDN that resolves the IP address of the internal interface.
  A. The external firewall must allow these inbound connections to Expressway: SIP: TCP 5061: HTTPS: TCP 8443; XMPP: TCP 5222; Media: UDP 36002 to 59999.

  B. Advise the user to hang up and try again.
