QUESTION 51

The relationship between a Region and a Location is that the Region codec parameter is used between a Region and its configured Locations.

 

A.

TRUE

B.

FALSE

 

Answer: B

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

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.

 

How many route lists and route groups should be configured for AAR at a minimum?

 

A.

a single route list with a local route group for each site

B.

two route lists and two route groups for each site

C.

a single route list and four route groups for each sitea

D.

None. The AAR C

SS can point directly to the route pattern.

 

Answer: A

 

 

QUESTION 53

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

QUESTION 59

Which two features require or may require configuring a SIP trunk? (Choose two.)

 

A.

SIP gateway

B.

Call Control Discovery between a Cisco Unified Communications Manager and Cisco Unified Communications Manager Express

C.

Cisco Device Mobility

D.

Cisco Unified Mobility

E.

registering a SIP phone

 

Answer: AB

Explanation: Incorrect answer: CDE

All protocols require that either a signaling interface (trunk) or a gateway be created to accept and originate calls. Device mobility allows Cisco Unified Communications Manager to determine whether the phone is at its home location or at a roaming location. Cisco Unified Mobility gives users the ability to redirect incoming IP calls from Cisco Unified Communications Manager to different designated phones, such as cellular phones.
