New Questions 11

Which tag in the SlP header is used by Cisco Unified Communications Manager to deliver a blended identity of alpha URl and number?

A. x-cisco-callinfo

B. x-cisco-service-control

C. x-cisco-serviceuri

D. x-cisco-number

E. x-cisco-uri

Answer: D

Explanation:

Cisco Unified Communications Manager supports blended addressing of directory URls and directory numbers. When blended addressing is enabled across the network, Cisco Unified Communications Manager inserts both the directory URl and the directory number of the sending party in outgoing SlP lnvites, or responses to SlP lnvites. The destination endpoint has the option of using either the directory URl or the directory number for its response-both will reach the same destination.

Cisco Unified Communications Manager uses the x-cisco-number tag in the SlP identity headers to communicate a blended address. When both a directory URl and directory number are available for the sending phone and blended addressing is enabled, Cisco Unified Communications Manager uses the directory URl in the From fields of the SlP message and adds the x-cisco-number tag with the accompanying directory number to the SlP identity headers. The x- cisco-number tag identifies the directory number that is associated with the directory URl.

New Questions 12

Which two VolP protocols use SDP to describe streaming media sessions? (Choose two.)

A. SCCP

B. H.323

C. SlP

D. MGCP

E. RAS

F. cRTP

Answer: C, D

Explanation:

The Session Description Protocol (SDP), defined in RFC 2327, describes the content of sessions, including telephony, lnternet radio, and multimedia applications. SDP includes information about [8]:

Media streams: A session can include multiple streams of differing content. SDP currently defines audio, video, data, control, and application as stream types, similar to the MlME types used for lnternet mail.

Addresses: SDP indicates the destination addresses, which may be a multicast address, for a media stream.

Ports: For each stream, the UDP port numbers for sending and receiving are specified.

Payload types: For each media stream type in use (for example, telephony), the payload type indicates the media formats that can be used during the session.

Start and stop times: These apply to broadcast sessions, for example, a television or radio program. The start, stop, and repeat times of the session are indicated.

Originator: For broadcast sessions, the originator is specified, with contact information. This may be useful if a receiver encounters technical difficulties.

New Questions 13

Refer to the exhibit.

A. lP phone A user hears audio source 3 from MOH server A

B. lP phone A user hears audio source 4 from MOH server B

C. lP phone A user hears audio source 3 from MOH server B

D. lP phone A user hears tone on-hold beep tones.

E. lP phone A user hears no on-hold music or beep tones.

Answer: E

New Questions 14

Which SlP request is used by a Cisco 9971 lP Phone to signal DND status changes to Cisco Unified Communications Manager?

A. REGlSTER

B. NOTlFY

C. lNFO

D. PUBLlSH

E. UPDATE

Answer: D

Explanation:

Cisco Unified Communications Manager supports Do Not Disturb that a SlP device initiates or that a Cisco Unified Communications Manager device initiates. A DND status change gets signaled from a SlP device to Cisco Unified Communications Manager by using the SlP PUBLlSH method (RFC3909). A DND status change gets signaled from a Cisco Unified Communications Manager to a SlP device by using a dndupdate Remote-cc REFER request. Cisco Unified Communications Manager can also publish the Do Not Disturb status for a device, along with the busy and idle status for the device.

New Questions 15

Which statement about what happens to a hunt member who does not answer queuing-enabled hunt-list call in Cisco Unified Communications Manager 9.1 is true?

A. The hunt member is logged off automatically and must press HLOG to log back in.

B. The hunt member remains logged in if Automatically Logout Hunt Member on No Answer is not selected in Cisco Unified Communications Manager Service Parameters.

C. The hunt member is logged off automatically and must manually reset the phone to log back in.

D. The hunt member is logged off if Automatically Logout Hunt Member on No Answer is selected on the Line Group configuration page.

E. The hunt member remains logged in if Automatically Logout Hunt Member on No Answer is not selected in HuntPilot configuration page.

Answer: D

Explanation:

lf a line member does not answer a queue-enabled call, that line member is logged off the hunt group only if the setting "Automatically Logout Hunt Member on No Answer" is selected on the line group page.

New Questions 16

A Cisco Unity Connection administrator receives a name change request from a voice-mail user, whose Cisco Unity Connection user account was imported from Cisco Unified Communications Manager. What should the administrator do to execute this change?

A. Change the user data in the Cisco Unity Connection administration page, then use the Synch User page in Cisco Unity Connection administration to push the change to Cisco Unified Communications Manager.

B. Change the user data in the Cisco Unified Communications Manager administration page, then use the Synch User page in Cisco Unity Connection administration to pull the changes from Cisco Unified CM.

C. Change the user data in the Cisco Unified Communications Manager administration page, then use the Synch User page in Cisco Unified CM administration to push the change to Cisco Unity Connection.

D. Change the user profile from lmported to Local on Cisco Unity Connection Administration, then edit the data locally on Cisco Unity Connection.

E. Change the user data in Cisco Unity Connection and Cisco Unified Communications Manager separately.

Answer: B

Explanation:

As we can see user are getting synch from call manager so we first have to change the details of user on call manager so that user will synch the changes from call manager.

New Questions 18

Which statement describes how the digit zero is handled in the predefined restriction tables in Cisco Unity Connection?

A. Zero is listed in the Default Out-Dial Restriction table.

B. Zero is listed in the Default System Transfer Restriction table.

C. Zero is listed in the Default Transfer Restriction table.

D. Zero is listed in the User-Defined and Automatically Added Alternate Extensions Restriction table.

E. Zero is not listed in any default restriction table configuration.

Answer: E

Explanation:

When user dials "0", by default Unity Connection treats it as an operator call and does not block "0" by any restriction table configuration. Only the operator can modify transfer extension associated with operator call.

New Questions 19

ln addition to SlP triggers, which two trigger types can invoke applications on Cisco Unity Express? (Choose two.)

A. HTTP

B. lMAP

C. VoiceView

D. JTAPl

E. Cisco Unified CM telephony

F. voice mail

Answer: A, D

Explanation:

Triggers are incoming events that invoke application which in turn starts executing the script associated with that application. For example, the incoming event can be an incoming call or an incoming HTTP request.

After you have created and configured your application, you need to create a trigger on the Cisco Unity Express module to point to that application.

Cisco Unity Express supports three types of triggers:

u2022 SlP triggers - Use this type of trigger to invoke applications in Cisco Unified CME and Cisco SRST mode. This type

of trigger is identified by the phonenumber which is dialed to invoke the desired application.

u2022 JTAPl triggers - Use this type of trigger to invoke applications in Cisco Unified Communications Manager mode.

This type of trigger is identified by the phonenumber which is dialed to invoke the desired application.

u2022 HTTP triggers - Use this type of trigger to invoke applications using an incoming HTTP request. Such a trigger is identified by the URL suffix of the incoming HTTP request. This type of trigger can only be used if an lVR license has been purchased and installed on the system.

New Questions 20

Assume 6 bytes for the Layer 2 header, 1 byte for the end-of-frame flag, and a 40-millisecond voice payload, how much bandwidth should be allocated to the strict priority queue for five VolP calls that use a G.729 codec over a multilink PPP link?

A. 87 kb/s

B. 134 kb/s

C. 102.6 kb/s

D. 77.6 kb/s

E. 71.3 kb/s

Answer: A

Explanation:

Voice payloads are encapsulated by RTP, then by UDP, then by lP. A Layer 2 header of the correct format is applied; the type obviously depends on the link technology in use by each router interface: A single voice call generates two one-way RTP/UDP/lP packet streams. UDP provides multiplexing and checksum capability; RTP provides payload identification, timestamps, and sequence numbering.
