QUESTION 111

Refer to the exhibit. A user is going through a series of dialing steps on a SIP Type B IP phone (for example, a Cisco 7975) to call an SCCP IP phone. Both phones are registered to the same Cisco Unified Communications Manager cluster. Assuming the calling SIP phone is associated with a SIP Dial Rule with a pattern value of 2001, which statement about the call setup process of this call is true?

 

clip_image002

 

A.

Each digit will arrive at Cisco Unified Communications Manager in a SIP NOTIFY message as a KPML event, and Cisco Unified Communications Manager will extend the call as soon as the collected digits match the extension of the SCCP IP phone, bypassing class of service configuration on both IP phones.

B.

Each digit will arrive at Cisco Unified Communications Manager in a SIP NOTIFY message as a KPML event. When the collected digits match the extension of the SCCP IP phone, Cisco Unified Communications Manager will extend the call only if the class of service configuration on both phones permits this action.

C.

As soon as the user selects the Dial softkey, the SIP IP phone will forward all digits to Cisco Unified Communications Manager in a SIP INVITE message. Cisco Unified Communications Manager will extend the call as soon as the collected digits match the extension of the SCCP IP phone, bypassing class of service configuration on both IP phones.

D.

As soon as the user selects the Dial softkey, the SIP IP phone will forward all digits to Cisco Unified Communications Manager in a SIP INVITE message. Cisco Unified Communications Manager will extend the call only if class of service configuration on both phones permits this action.

E.

The SIP IP phone will wait for the interdigit timer to expire, and then send all digits to Cisco Unified Communications Manager in a SIP INVITE message. Cisco Unified Communications Manager will extend the call as soon as the collected digits match the extension of the SCCP IP phone, bypassing class of service configuration on both IP phones.

 

Correct Answer: D

Explanation:

Cisco Type B SIP Phones offer functionality based SIP INVITE Message. Every key the end user presses triggers an individual SIP message. The first event is communicated with a SIP INVITE, but subsequent messages use SIP NOTIFY messages. The SIP NOTIFY messages send KPML events corresponding to any buttons or soft keys pressed by the user. Cisco Type B SIP IP Phones with SIP dial rules operate in the same manner as Cisco Type A phones with dial rules.

 

 

QUESTION 112

Which design restriction applies to Cisco Unified Communications Manager Session Management Edition clustering over the WAN deployment with extended round-trip times in Cisco Unified CM 9.1 and later releases?

 

A.

SIP and H.323 intercluster trunks are supported.

B.

Only SIP trunk is supported.

C.

SIP trunks and H.323 gateways are supported.

D.

A minimum of 1.544 Mb/s bandwidth is required for all traffic between any two nodes in the cluster.

E.

Only RSVP agents can be configured and registered to the SME cluster as media resources.

 

Correct Answer: B

Explanation:

Using only SIP trunks in the SME cluster allows you to deploy a “media transparent” cluster where media resources, when required, are inserted by the end or leaf Unified Communications system and never by SME. Using only SIP trunks also allows you to use extended round trip times (RTTs) between SME nodes when clustering over the WAN.

 

 

QUESTION 113

Which two applications must be connected to a leaf cluster in a Cisco Unified Communications Manager Session Management Edition deployment? (Choose two.)

 

A.

Cisco Unified Meeting Place

C.

H.323-based video conferencing systems

D.

Cisco Unity

E.

Cisco Unified Communications Manager

F.

fax servers

 

Correct Answer: BE

Explanation:

The deployment of a Unified CM Session Management Edition enables commonly used applications, such as conferencing or videoconferencing to connect directly to the session management cluster, which reduces the overhead of managing multiple t
runks to leaf systems.

Unified CM Session Management Edition supports the following applications:

 

clip_image003

Unity, Unity Connection

Meeting Place, Meeting Place Express

SIP and H.323-based video conferencing systems

Third Party voice mail systems

QUESTION 114

Which two Device Pool configuration settings will override the device-level settings when a device is roaming within or outside a device mobility group? (Choose two.)

 

A.

Adjunct CSS

B.

Device Mobility CSS

C.

Network Locale

D.

Called Party Transformation CSS

E.

AAR CSS

F.

Device Mobility Group

 

Correct Answer: CF

Explanation:

The parameters under these settings will override the device-level settings when the device is roaming within or outside a Device Mobility Group. The parameters included in these settings are:

 

Date/time Group

Region

Media Resource Group List

Location

Network Locale

SRST Reference

Physical Location

Device Mobility Group

 

The roaming sensitive settings primarily help in achieving proper call admission control and voice codec selection because the location and region configurations are used based on the device’s roaming device pool.

QUESTION 115

Router A and router B are Cisco IOS routers with hardware CFB resources that are registered to the same Cisco Uni
fied Communications Manager server. Which Media Resource Group and Media Resource Group List configuration should be implemented if an administrator wants to make sure that all provisioned DSPs on router A are consumed before router B’s DSP is used?

 

A.

Router A’s CFB and router B’s CFB should each be configured in its own MRG. Both MRGs should then be grouped into the same MRGL, but the MRG that contains router A’s CFB should be listed in higher order than the MRG that contains router B’s CFB. Finally, associate the MRGL to all conference resource consumers.

B.

Router A’s CFB and router B’s CFB should each be configured in its own MRG. Both MRGs should then be further separated into different MRGLs. Finally, associate the MRGL that contains router A’s CFB in higher order than router B’s CFB to all conference resource consumers.

C.

Router A’s CFB and router B’s CFB should both be configured in the same MRG with router A’s CFB listed higher than that of router

B.Then associate the MRG with an MRGL and apply it to all conference resource consumers.

D.

Router A’s CFB and router B’s CFB should both be configured in the same MRG. Make sure router A’s CFB is listed in a higher alphabetical order than router B’s CFB. Then associate the MRG with an MRGL and apply it to all conference resource consumers.

E.

Router A’s CFB and router B’s CFB should both be configured in the same MRG. Use Cisco Unified Communications Manager service parameters to assign a higher priority to router A’s CFB. Then associate the MRG with an MRGL and apply it to all conference resource consumers.

 

Correct Answer: A

 

 

QUESTION 116

What is the maximum length of any numeric geographic area address in ITU recommendation E.164?

 

A.

15

B.

18

C.

21

D.

22

E.

25

 

Correct Answer: A

Explanation:

E.164 defines a general format for international telephone numbers. Plan-conforming numbers are limited to a maximum of 15 digits. The presentation of numbers is usually prefixed with the character + (plus sign), indicating that the number includes the international country calling code (country code), and must typically be prefixed when dialing with the appropriate international call prefix, which is a trunk code to reach an international circuit from within the country of call origination.

 

 

QUESTION 117

Which Call Control Discovery function allows the local Cisco Unified Communications Manager to listen for advertisements from remote call-control entities that use the SAF network?

 

A.

CCD advertising service

B.

CCD requesting service

C.

SAF forwarder

D.

SAF enabled trunks

E.

CCD registration service

 

Correct Answer: B

Explanation:

SAF and CCD will allow large distributed multi-cluster deployments to have the directory number (DN) ranges of each call routing element advertised dynamically over SAF. Cisco routers act as SAF Forwarders (SAFF), while the call routing elements (e.g. CUCM) act as clients that register with the routers to advertise their DN ranges and listen to the advertisements of other routers.
