Q52. How does the system intelligently shift call processing upon restoration of WAN connectivity? 

A. automatically back to the primary Cisco Unified Communications Manager cluster 

B. manually back to the primary Cisco Unified Communications Manager cluster 

C. automatically back to the secondary Cisco Unified Communications Manager cluster

Q53. The relationship between a Region and a Location is that the Region codec parameter is combined with Location bandwidth when communicating with other Regions. 

A. FALSE 

B. TRUE 

Answer: A 

Explanation: 

Locations work in conjunction with regions to define the characteristics of a network link. Regions define the type of compression (G.711, G.722, G.723, G.729, GSM, or wideband) that is used on the link, and locations define the amount of available bandwidth for the link Link:

Q54. 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 

Communications Manager using the domain name. 

Answer: B 


Q55. Which task must you perform before deleting a transcoder? 

A. Delete the dependency records. 

B. Unassign it from a media resource group.
