QUESTION 12

When multiple Cisco Extension Mobility profiles exist, which actions take place when a user tries to log in to Cisco Extension Mobility?

 

A.

The login will fail because only a single Cisco Extension Mobility profile is allowed.

B.

The user must select the desired profile.

C.

The user must login to both profiles in the order they are presented.

D.

The user may login to both profiles in any order.

E.

Login will only be allowed to multiple profiles if the service parameter Allow Multiple Logins is enabled.

 

Answer: B

Explanation: Incorrect answer: ACDE

Users access Cisco Extension Mobility by pressing the Services or Applications button on a Cisco Unified IP Phone and then entering login information in the form of a Cisco Unified Communications Manager UserID and a Personal Identification Number (PIN). If a user has more than one user device profile, a prompt displays on the phone and asks the user to choose a device profile for use with Cisco Extension Mobility.

A.

Shut down the Cisco Unified Communications Manager Servers.

B.

Answer: C

 

 

QUESTION 14

Refer to the exhibit.

 

clip_image001

 

 

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 nationa
l 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.

 

Which partition should be configured in the AAR CSS applied at the phones?

 

A.

PSTN partition

B.

LD partition

C.

The HQ AAR CSS must include a partition assigned to route pattern 91408XXXXXXX. The BR1 AAR CSS must include a partition assigned to route pattern 91650XXXXXXX.

D.

AAR CSS must contain translation pattern 9.1[2-9]XX[2-9]XXXXXX for each site that must be globalized. Otherwise the called numbers will not be localized at the egress gateway.

 

Answer: A

 

 

QUESTION 15

Which statement about H.323 Gatekeeper Call Admission Control is true?

 

A.

Gatekeeper Call Admission Control applies to centralized Cisco Unified Communications deployments that use locations based Call Admission Control.

B.

Gatekeeper Call Admission Control applies to distributed Cisco Unified Communications deployments.

C.

Gatekeeper Call Admission Control applies only to distributed Cisco Unified Communications Express deployments.

D.

Gatekeeper Call Admission Control setting is configured in Cisco Unified Communications Manager.

 

Answer: B

Explanation: Incorrect answer: ACD

in distributed call processing deployments on a simple hub-and-spoke topology, you can implement call admission control with a Cisco IOS gatekeeper. In this design, the call processing agent (which could be a Unified CM cluster, Cisco Unified Communications Manager Express (Unified CME), or an H.323 gateway) registers with the Cisco IOS gatekeeper and queries it each time the agent wants to place an IP WAN call.

QUESTION 16

You want to perform Media Control Gateway Protocol gateway maintenance. For this purpose, you disable Media Control Gateway Protocol gateway using the no mgcp command.

 

After you perform the maintenance, you want to enable the Media Control Gateway Protocol gateway. Which command should you use?

 

A.

enable mgcp

B.

mgcp

C.

mgcp enable

D.

mgcp yes

E.

activate mgcp

F.

mgcp active

 

Answer: B

 

 

QUESTION 17

Refer to the exhibit.

 

 

 

clip_image002

 

When the user of a phone registered to the Cisco Unified Communications Manager places a call to 3001 when the SAF network is down, what happens?

 

A.

The call fails.

B.

The call is rerouted to the PSTN with the constructed PSTN number as +442288223001

C.

The call is rerouted to the PSTN with the constructed PSTN number as 442288223001

D.

The call is rerouted to the PSTN with the constructed PSTN number as 0002288223001

E.

The call is rerouted to the PSTN with the constructed PSTN number as +0002288223001

 

Answer: A

Explanation: Incorrect answer: BCD

When the SAF forwarder loses network connection with its call-control entity, the SAF forwarder withdraws those learned patterns that were published by the call control entity. In this case, CCD requesting service marks those learned patterns as unreachable via IP, and the calls gets routed through the PSTN gateway.

QUESTION 19

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: AD

Explanation: Incorrect answer: BCEF

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.

QUESTION 20

Refer to the exhibit.

 

clip_image003

 

The exhibit shows centralized Cisco Unified Communications Manager configuration components for TEHO calls to U.S. area code 408 from the U.

K.The PSTN access code for the U.

K.is 9 and 001 for international calls to the U.S. What should the TEHO-US route list configuration consist of?

 

A.

First route group should point only to the U.

K.gateway. The second route group should point to the U.S. gateway.

B.

First route group should be only the local route group. The second route group should point to the U.S. gateway.

C.

First route group should point only to the U.S. gateway. The second route group should be the local route group.

D.

The TEHO-US route list should contain only the local route group. The globalized configuration means that the appropriate gateway will be selected automatically.

E.

The +! route pattern should point directly to the U.S. gateway.

 

Answer: C

Explanation: Incorrect answer: ABD

The route group points to one or more gateways and can choose the gateways for call routing based on preference. The route group can serve as a trunk group by directing all calls to the primary device and then using the secondary devices when the primary is

 

 

 

unavailable. One or more route lists can point to the same route group.
