Q15. Which method can be used to address variable-length dial plans?

A. Overlap sending and receiving.

B. Add a prefix for all calls that are longer than 10-digits long

C. Use nested translation patterns to eliminate inter-digit timeout

D. Use the @macro on the route pattern

E. Use MGCP gateways, which support variable-length dial plans

Answer: A

Explanation: Incorrect: BCDE

If the dial plan contains overlapping patterns, Cisco Unified Communications Manager does not route the call until the interdigit timer expires (even if it is possible to dial a sequence of digits to choose a current match). Check this check box to interrupt interdigit timing when Cisco Unified Communications Manager must route a call immediately.

By default, the Urgent Priority check box displays as checked. Unless your dial plan contains overlapping patterns or variable length patterns that contain!, Cisco recommends that you do not uncheck the check box.

Q17. Which statement is not true about GARP? (SourcE. Hardening the IP Phone)

A. GARP attacks require access to the target LAN or VLAN.

B. GARP can be used for a man-in-the-middle attack.

C. GARP is normally used for HSRP.

D. GARP can be disabled at Cisco IP phones.

Answer: C

Explanation: Incorrect: ABD

Q18. When an external call is placed from Ajax, they would like the ANI that is sent to the PSTN to be the main number, not the extension. For domestic calls, they would like 10 digits sent; for international calls, they would like to send the country code 1 and the 10 digits. How can this be accomplished?

A. Add a translation pattern to the dial peers in the gateway that adds the appropriate digits to the outgoing ANI.

B. In the external call route patterns, set the external phone number mask to the main number. Use 10 digits in the domestic route pattern and 1 followed by the main number digits in the international route patterns.

C. Use a calling party transform mask for each route group in the corresponding route list configuration. Set the explicit 10-digit main number for domestic calls and 1 followed by the main number for the international route patterns.

D. In the directory number configurations, set the prefix digits field to the country code and the 10 digits of the main number. This will be truncated to the 10-digit number for domestic calls and sent out in its entirety for international calls.

Answer: C

Explanation: Incorrect: ABD

calling party transformation mask value is Valid entries for the NANP include the digits 0 through 9; the wildcard characters X, asterisk (*), and octothorpe (#); and the international escape character +.

Q19. Refer to the exhibit.

A PSTN call arrived at the MGCP gateway. The calling number was received as 14087071222 with number set to type international. The HQ_clng pty_CSS contains the HQ_clng_pty Pt partition. Which caller ID is displayed on the IP phone?

A. +087071222

B. 14087071222

C. 087071222

D. 4087071222

E. 14087071222

Answer: C

Explanation: Incorrect: ABDE

SIP trunks and MGCP gateways can support sending the international escape character, +, for calls. H.323 gateways do not support the +. QSIG trunks do not attempt to send the +. For outgoing calls through a gateway that supports +, Cisco Unified Communications Manager can send the + with the dialed digits to the gateway. For outgoing calls through a gateway that does not support +, the gateway strips the + when Cisco Unified Communications Manager sends the call information to the gateway.

Q20. When implementing a dial plan for multisite deployments, what must be present for SRST to work successfully?

A. dial peers that address all sites in the multisite cluster

B. translation patterns that apply to the local PSTN for each gateway

C. incoming and outgoing COR lists

D. configuration of the gateway as an MGCP gateway

Answer: B

Q21. Which two locations are the best locations that an end user can use to determine if an IP phone is working in SRST mode? (Choose two.)

A. Cisco Unified Communications Manager Administration

B. IP phone display

C. Cisco Unified SRST Router

D. Cisco Unified MGCP Fallback Router

E. physical IP phone settings

Answer: B,E

Explanation: Incorrect: ACD

IP Phone display and Physical phone IP settings are two locations were an end user can determine if an IP phone is working in SRST mode.

Q22. Which command is needed to utilize local dial peers on an MGCP-controlled ISR during an SRST failover?

A. ccm-manager fallback-mgcp

B. telephony-service

C. dialplan-pattern

D. isdn overlap-receiving

E. voice-translation-rule

Answer: A

Q23. During device failover to the secondary Cisco Unified Communications Manager server, how does the phone recognize that the primary server is back?

A. The secondary server keeps sending keepalive message to the primary server and when it succeeds, it unregisters the phones to force them to register to the primary.

B. When the primary server goes online, it sends out an "ALIVE" message via broadcast so that the phones re-register.

C. The phones never re-register with the primary server until the active (secondary) one goes down.

D. The phone sends keepalive messages to the primary server frequently and when it succeeds, the phone re-registers with it.

Answer: D

Q24. Which two statements about the functionality of a gatekeeper are true? (Choose two.)

C. Cisco Unified Communications Manager registers with a gatekeeper via H.323.

D. A gatekeeper can enable CAC and AAR.

E. A gatekeeper can enable CAC, but not AAR.

Answer: C,E
