Q1. When Cisco Extension Mobility is implemented, which CSS is used for calling privileges? 

A. The user device profile line CSS combined with the device CSS of the physical phone used to log in the extension mobility user. 

B. The user device profile device CSS combined with the line CSS of the physical phone used to log in the extension mobility user. 

C. Only the user device profile device CSS is used. 

D. The combined line/device CSS of the physical phone is used to log in the extension mobility user. 

E. The combined line/device CSS of the user device profile. 

Answer:

Q2. When a call is made from a video endpoint to a Cisco TelePresence EX90 that is registered to a Cisco VCS Control, which portion of the destination URI is the first match that is attempted? 

A. the full URI, including the domain portion 

B. the destination alias, without the domain portion 

C. the E.164 number that is assigned to the Cisco TelePresence EX90 

D. the directory number that is assigned to the Cisco TelePresence EX90 

Answer:

Q3. 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:

Q4. Which statement best describes globalized call routing in Cisco Unified Communications Manager? 

A. All incoming calling numbers on the phones are displayed as an E.164 with the + prefix. 

B. Call routing is based on numbers represented as an E.164 with the + prefix format. 

C. All called numbers sent out to the PSTN are in E.164 with the + prefix format. 

D. The CSS of all phones contain partitions assigned to route patterns that are in global format. 

E. All phone directory numbers are configured as an E.164 with the + prefix. 

Answer:

Explanation: 

Incorrect Answer: A, C, D, E For the destination to be represented in a global form common to all cases, we must adopt a global form of the destination number from which all local forms can be derived. The + sign is the mechanism used by the ITU's E.164 recommendation to represent any PSTN number in a global, unique way. This form is sometimes referred to as a fully qualified PSTN number.

Q5. You are deploying a Cisco Unified Communications Manager solution with MGCP gateways at multiple locations. Which firewall and ACL configuration must you perform to allow the MCGP gateways to function correctly? 

A. Allow access to TCP port 2428. 

B. Block TCP port 1720. 

C. Open access to all TCP and UDP ports. 

D. Allow access to TCP port 1720. 

E. Block access to TCP ports 2427 and 2428. 

Answer:

Q6. 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. 

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 site 

D. None. The AAR CSS can point directly to the route pattern. 

Answer:

Q7. You are entering the description for the Service Advertisement Framework forwarder. 

Which three characters should you avoid entering in the description? (Choose three.) 

A. < > 

B. & 

C. % 

D. # 

E. $ 

F. @ 

Answer: A,B,C 

Q8. Which two actions ensure that the call load from Cisco TelePresence Video Communication Server to a Cisco Unified Communications Manager cluster is shared across Unified CM nodes? (Choose two.) 

A. Create a neighbor zone in VCS with the Unified CM nodes listed as location peer addresses. 

B. Create a single traversal client zone in VCS with the Unified CM nodes listed as location peer addresses. 

C. Create one neighbor zone in VCS for each Unified CM node. 

D. Create a VCS DNS zone and configure one DNS SRV record per Unified CM node. 

E. In VCS set Unified Communications mode to Mobile and remote access and configure each Unified CM node. 

Answer: A,D 

Q9. Which command can be used to manually send the MGCP gateway to register with the secondary Cisco Unified Communications Manager server? 

A. ccm-manager switchover-to-backup 

B. mgcp use backup 

C. ccm-manager register backup 

D. not supported 

Answer:
