Q21. Which two configurations provide the best SIP trunk redundancy with Cisco Unified Communications Manager? (Choose two.)
A. Configure all SIP trunks with DNS SRV
B. Configure all SIP trunks with Cisco Unified Border Element
C. Configure all SIP trunks to point to a SIP gateway
D. Configure SIP trunks to be members of route groups and route lists
E. Configure all SIP trunks to allow TCP ports 5060
F. Configure all SIP trunks to point to a gatekeeper through SIP to H.323 gateway
Answer: A,D
Explanation:
Incorrect Answer: B, C, E, F For SIP trunks, Cisco Unified Communications Manager supports up to 16 IP addresses for each DNS SRV and up to 10 IP addresses for each DNS host name. The order of the IP addresses depends on the DNS response and may be identical in each DNS query. The OPTIONS request may go to a different set of remote destinations each time if a DNS SRV record (configured on the SIP trunk) resolves to more than 16 IP addresses, or if a host name (configured on the SIP trunk) resolves to more than 10 IP addresses. Thus, the status of a SIP trunk may change because of a change in the way a DNS query gets resolved, not because of any change in the status of any of the remote destinations.

Q22. A voice-mail product that supports only the G.711 codec is installed in headquarters.
Which action allows branch Cisco IP phones to function with voice mail while using only the G.729 codec over the WAN link to headquarters?
A. Configure Cisco Unified Communications Manager regions.
B. Configure transcoding within Cisco Unified Communications Manager.
C. Configure transcoding resources in Cisco IOS and assign to the MRGL of Cisco IP phones.
D. Configure transcoder resources in the branch Cisco IP phones.
Answer: C
Q23. Refer to the exhibit.
You have configured transcoder resources in both an IOS router and a Cisco Unified Communications Manager. When you review the configurations in both devices the IP addresses and transcoder names are correct, but the transcoder is failing to register with the Cisco Unified Communications Manager. Which command needs to be edited to allow the transcoder to register properly?
A. The associate profile and dsp farm profile numbers need to match associate ccm 2 command.
B. The associate ccm 2 priority 1 command needs to be changed so the ccm value matches identifier 1 in the sccp ccm 10.1.1.1 command.
C. The sccp ccm group number needs to match the associate ccm 2 command.
D. The maximum sessions command must match the number of codecs configured under the dsp farm profile.
E. The sccp ccm group number must match the voice-card number.
Answer: B
Explanation:
Incorrect Answer: A, C, D, E The value of the IP address should match the IP address in the ip source-address command Link:

A. H.323
B. SIP
C. Skinny
D. H.248
Answer: A
Q27. Refer to the exhibit.
When a user presses a speed dial to +442079460255 when the SAF network is down, which event should occur?
A. The call will reroute via the PSTN with the constructed PSTN number as 442079460255.
B. The call will reroute via the PSTN with the constructed PSTN number as +442079460255.
C. The call will reroute via the PSTN with the constructed PSTN number as 00442079460255.
D. The call will fail because the ToDID is 0:.
E. The call will fail because the called number will be 2079460255.
Answer: B
Q28. Refer to the exhibit.
The HQ site uses area code 650. The BR1 site uses area code 408. The long distance national code for PSTN dialing is 1. To make a long distance national call, an HQ or BR1 user dials access code 9, followed by 1, and then the 10-digit number. Both sites use MGCP gateways. AAR must use globalized call routing using a single route pattern. Assume that all outgoing PSTN numbers are localized at the egress gateway as shown in the exhibit.
What should the AAR group prefix be?
A. 9
B. 91
C. none
D. +
E. +1
Answer: C
Q29. Refer to the exhibit.
