QUESTION NO:1
Ajax has completed its IP telephony rollout. The legacy PBX has been removed, and the entire phone system is now on IP using Cisco Unified Communications Manager for call processing control.
Ajax has recently acquired Best Auto Accessories in Redmond, WA. Best is a small distributor of automobile parts and accessories. Best has 36 office employees and 48 warehouse workers in a single building. The Best phone system consists of a four-year-old key system. All calls enter the company through the company operator who then uses the overhead paging system to inform users of incoming calls.
Ajax plans to integrate Best as a remote site into the new Cisco IP telephony system at Ajax. The 36 office employees will be converted to IP phones with DID along with two phones in the warehouse that will not be DID. All IP phones will register with the Cisco Unified Communications Manager cluster at the Ajax central campus.
Ajax plans to connect with Best via a point-to-point circuit. The Redmond office will maintain external connections to the PSTN but will use the connection with Ajax to carry internal calls and for Internet connectivity. Internal calls crossing the WAN will use a G.729 codec with 20ms payload for bandwidth savings. Call Admission Control will be implemented using locations. The voice-mail system only supports the G.711 codec and will be centralized with the Cisco Unified Communications Manager.
With respect to the function of low latency queuing, how does the operation of the PQ differ from the CBWFO?
A. Both queuing methods work in a similar manner. The difference is in the classification methods.
B. The CBWFOs are set to a minimum bandwidth that is policed. The PQ is set to a maximum bandwidth that is also policed.
C. The PQ is set to a maximum bandwidth that is policed. Each queue within the CBWFG is set for a minimum bandwidth that can be metered on a per queue basis to control bandwidth consumption.
D. The PQ uses a minimum bandwidth that uses an internal metering method that drops packets as the bandwidth gets closerthe maximum threshold. The CBWFQs are set to a minimum bandwidth per queue and controlled through metering as each queue reaches a maximum level.
Answer: C

If connectivity to the PSTN is lost in Redmond, external calls should be routed through the PSTN gateway at the Ajax location. This should be transparent to the user, so a local call should still only require seven-digit dialing. How can this be accomplished for local calls from Redmond?
A. Build a translation pattern that adds 1425 to a dialed seven-digit number and place this in a partition in the local call search space. When a local call fails at the local gateway, the translation pattern is applied and the call is routed out the Ajax PSTN gateway.
B. Add a secondary route pattern for Redmond that points to the PSTN gateway at Ajax that adds 1425 using the called party transform mask. When the call fails using the first route pattern, it will fall back to the secondary and complete the call.
C. Build another route list for the Redmond site that points to the route group at Ajax that contains the PSTN gateway. Have this route list add 1425 using the called party transform mask.
D. Build another route group for the Redmond site that points to the PSTN gateway at Ajax and has a prefix configured that adds 1425. Have the existing route list point to the new route group as a second option.
Answer: D

You are going to implement remote site survivability for the Redmond site and must decide between SRST and Cisco Unified Communications Manager Express in SRST mode. Which of the following statements is true?
A. Cisco Unified Communications Manager Express in SRST mode is needed to support CUE at the remote site in the event of a WAN failure.
B. Cisco Unified Communications Manager Express in SRST mode supports a superset of the features and functionality that SRST supports, but supports fewer phones.
C. Cisco Unified Communications Manager Express in SRST mode does not support SIP phones. SIP SRST may be configured on the same router to support SIP phones.
D. When the local phones registerto a Cisco Unified Communications Manager Express in SRST mode, the router can be configured to save the ephone-dns and ephone configurations in its running configuration, which makes failovertime faster during subsequent WAN outages.
