• Question 14:

  The Session Border Controller is not routing calls to a specific SIP endpoint from the backbone realm to the access realm in an Access-Backbone architecture.

  How can you troubleshoot this routing issue?

  A. by running the notify berpd force command

  B. by running the show sipd endpoint-ip command

  C. by checking the sip-manipulation configuration element used for routing from the backbone realm to the access realm

  D. by checking the registration-cache configuration element used for routing from the access realm to the backbone realm

  E. by checking the local-policy configuration element used for routing from the access realm to the backbone realm

  Correct Answer: D

• Question 15:

  When setting up the registration-caching parameter to enabled in the sip-interface configuration element, _____________.

  B. the Session Border Controller will not use the registration cache for routing

  C. all endpoints in the realm will be cached when registered

  D. only endpoints behind NAT in the realm will be cached when registered

  E. the Session Border Controller will never use the local-policy mechanism for routing

  Correct Answer: A

• Question 19:

  You are configuring steering pools. After executing the done command, you get this error message:

  error 409 saving configuration SteeringPool.

  Identify the cause ofthe error.

  A. The realm-id parameter value of the steering-pool refers to a realm-config element that already exists in the configuration.

  B. The ip-address parameter of the steering-pool has the same value as the address parameter of a sip-port configuration element.

  C. The realm-id parameter value of the steering-pool refers to a realm-config element that does not exist in the configuration.
