You can find the solutions to these questions in Appendix A, "Answers to Review Questions."
Which is a benefit associated with gatekeeper call admission control?
Without call admission control, what happens to existing calls when the next call oversubscribes the WAN?
Which two characteristics are associated with the distributed call-control environment? (Choose two.)
How do the Cisco IP Phones in a branch site know how to register to a gateway running SRST?
Using the Cisco CallManager locations feature, how many simultaneous audio calls can be placed over a given WAN link with 128 kbps of available bandwidth using a G.729 codec?
AAR derives the alternate dial string used to route the call over the PSTN from which three of the following? (Choose three.)
Which command is used to initiate SRST capabilities on an IOS-based router?
You are working in a location-based CallManager deployment. Phone A (DN=3423) dials onnet to Phone B (DN=3420). The location-based CAC denies the call and AAR initiates. Which external phone number mask will be used by AAR to complete the call?
What is the default state of AAR in a CallManager cluster?
You have AAR configured in a cluster to divert calls to the PSTN should the IP WAN become unusable. To test the configuration, you disconnect the WAN and place a call to an alternate site. The CallManager returns a reorder tone. You are sure the digit transformation settings are configured correctly; what is the most likely cause of this problem?
