A. The protocol that is used in Cisco Unified Communications Manager 

B. Cisco Unified Communications Manager version 

C. Cisco IOS Software version 

D. WAN link bandwidth 

E. capacity of the Cisco Media Convergence Server 

F. router platform 

Answer: C,F 

Q2. Which statement about SIP precondition is most correct? 

A. When configuring SIP precondition, the SIP trunk must have access to an RSVP agent. 

B. When configuring SIP precondition, the IP phones must have access to an RSVP agent. 

C. When configuring SIP precondition, the IP phones and SIP trunk must have access to an RSVP agent. 

D. RSVP agents are only required for the IP phones. SIP trunks require RSVP agents only when fall back to local RSVP is configured.

Q3. What is the difference between an MGCP gateway and a SIP gateway? 

A. An MGCP gateway that dial peers be configured before PSTN calls can be placed and received. The SIP gateway requires no dial peers. 

B. An MGCP gateway can be added in Cisco Unified Communications Manager under the Gateway Type field using the gateway model. The SIP gateway can connect to Cisco Unified Communications Manager only through a SIP trunk. 

C. A SIP gateway requires a call agent for PSTN calls to be placed and received. An MGCP gateway does not require a call agent for PSTN calls to be placed and received. 

D. An MGCP gateway can register with Cisco Unified Communications Manager. A SIP gateway will show status of "Unknown". 

E. The SIP gateway must be configured in Cisco Unified Communications Manager using a valid IP address on the gateway. The MGCP gateway must be configured in Cisco Unified

Q5. If your IP telephony administrator asks you to configure a local zone for your dial plan to control the volume of calls between two end points in a centralized multisite environment, which two types of Call Admission Control can be implemented? (Choose two.) 

A. locations based 

B. automated alternate routing 

C. gatekeeper based 

D. SRST 

E. Cisco Unified Communications Manager based 

Answer: A,B 

Explanation: 

Incorrect Answer: C, D, E Location-based call admission control (CAC) manages WAN link bandwidth in Cisco Unified Communications Manager. Automated alternate routing (AAR) provides a mechanism to reroute calls through the PSTN or other network by using an alternate number.

B. Cisco Unified Communications Manager Express in SRST mode supports more Cisco IP Phones than SRST. 

C. MGCP fallback is required for ISDN call preservation. 

D. MGCP fallback functions with SRST. 

Answer: A,D 

Q7. You recently implemented call redundancy at a new remote site, and users report that calls are dropped when the remote site supposedly is in SRST. Which two actions must you take to troubleshoot the problem? (Choose two.) 

A. Confirm that SRST is configured on the voice gateway. 

B. Confirm that the site has an SRST reference that is correctly associated with the Cisco Unified Communications Manager group. 

C. Confirm that a calling search space is assigned to the voice gateway in Cisco Unified Communications Manager. 

D. Confirm that the site devices are associated with a Cisco Unified Communications Manager group and that four Cisco Unified Communications Manager servers are available. 

E. Check the Region settings in Cisco Unified Communications Manager. 

F. Restart Cisco Unified Communications Manager services to confirm that the server is working correctly.
