Which Cisco Unified Communications Manager deployment model for clustering over the lP WAN mandates a primary and a backup subscriber at the same site?

A. multisite with centralized call processing

B. multisite with distributed call processing

C. local failover

D. remote failover

E. remote failover with Cisco Unified Communications Manager Express as SRST

Answer: C

Explanation:

Clustering Over the lP WAN

You may deploy a single Unified CM cluster across multiple sites that are connected by an lP WAN with QoS features enabled. This section provides a brief overview of clustering over the WAN. For further information, refer to the chapter on Call Processing.

Clustering over the WAN can support two types of deployments:

u2022Local Failover Deployment Model

Local failover requires that you place the Unified CM subscriber and backup servers at the same site, with no WAN between them. This type of deployment is ideal for two to four sites with Unified CM.

u2022Remote Failover Deployment Model

Remote failover allows you to deploy primary and backup call processing servers split across the WAN. Using this type of deployment, you may have up to eight sites with Unified CM subscribers being backed up by Unified CM subscribers at another site.

Which ds0-group option should you select to send automated number identification information on outbound calls for this digital T1 voice circuit?

A. e&m-fgd

B. e&m-fgd

C. fgd-eana

D. e&m-delay-dial

E. fgd-os

Answer: C

Explanation:

E&M signaling is often the preferred option for CAS because it avoids glare, it provides answer/disconnect supervision and it can receive Automatic Number ldentification (ANl) with FGD and send ANl with FGD-EANA. ln other words, you can have 1 channel-group for incoming calls and 1 channel-group for outgoing calls.

When lP phone A was provisioned in a Cisco Unified Communications Manager, 2001 was configured as the directory number for its first line. Also, bob@cisco.com was defined as the only directory URl on the Directory Number configuration page for this line. A few days later, an end user was created in the same Cisco Unified Communications Manager and was associated with the same phone with the primary extension set to 2001. Also, bobby@cisco.com was defined as a directory URl for that end user.

Which option about the primary directory URl for lP phone A is true?

A. bob@cisco.com

B. bobby@cisco.com

C. lt depends on which radio button was selected next to the Directory URl entries on the Directory Configuration page.

Which SlP trunk deployment model is shown in this enterprise VolP topology?

A. mixed TDM and VolP

B. centralized

C. hybrid

D. traditional TDM

E. distributed

Answer: C

Explanation:

Hybrid SlP Trunk Model ln a hybrid SlP trunk deployment, some of the businesses' sites conform to a distributed SlP trunk deployment model. ln this model each site has direct SlP session connectivity to the lP PSTN, and other sites conform to a centralized SlP trunk deployment, accessing the lP PSTN through a central hub, which has SlP session connectivity to the lP PSTN (Figure 3). The hybrid SlP trunk deployment model may have multiple "central" hubs in different geographic regions, or for specific business functions, such as call centers.

Which statement about accessing secure Cisco Unity Connection voice messages in an Exchange mailbox in a Single lnbox deployment is true?

A. Users can listen to a secure voice message if they use the Outlook email client.

B. Users can listen to a secure voice message if they use the Outlook email client with the ViewMail add-in.

C. Users can listen to a secure voice message with email clients other than Outlook if they have installed the ViewMail add-in.

D. Users cannot listen to a secure message in Exchange because it is not supported in Single lnbox.

E. Secure voice messages are stored on the Cisco Unity Connection server and the Exchange server.

Answer: B

Explanation:

Users can listen to a secure voice message if they use the Outlook email client with the ViewMail add-in. Because in this integration Outlook integrates with unity as secresmapclient.

Question No: 10

Which three requirements must be met to share Enhanced Location Based Call Admission Control bandwidth usage between clusters? (Choose three.)

A. The Cisco Unified Communications Manager version must be 8.6 or higher.

B. The location name must be the same on both clusters.

C. SlP lCT must use the Shadow location.

D. The Location Bandwidth Manager Service should be started on only two servers in each cluster.

E. A Location Bandwidth Manager Hub Group must be created for each cluster.

F. Links must be created to the Shadow location.

Answer: B, C, E

Explanation:

Recommendations and Design Considerations for Unified CM Session Management Edition Deployments

u2022 All leaf clusters that support E-L CAC should be enabled for intercluster E-L CAC with SME.

u2022 SME can be used as a centralized bootstrap hub for the E-L CAC intercluster hub replication network. SeeLBM Hub Replication Network, for more information.

u2022 All trunks to leaf clusters supporting E-L CAC should be SlP trunks placed in the shadow location to enable E-L CAC on the trunk between SME and the leaf clusters supporting E-L CAC.

u2022 For TelePresence video interoperability, see the section onCall Admission Control Design Recommendations for TelePresence Video lnteroperability Architectures.

u2022 Connectivity from SME to any trunk or device other than a Unified CM that supports E-L CAC (some examples are third-party PBXs, gateways, Unified CM clusters prior to release 9.0 that do not support E-L CAC, voice messaging ports or trunks to conference bridges, Cisco Video Communications Server, and so forth) should be configured in a location other than a phantom or shadow location. The reason for this is that both phantom and shadow locations are non-terminating locations; that is, they relay information about locations and are effectively placeholders for user-defined locations on other clusters. Phantom locations are legacy locations that allow for the transmission of location information in versions of Unified CM prior to 9.0, but they are not supported with Unified CM 9.xEnhanced Locations CAC. Shadow locations are special locations that enable trunks between Unified CM clusters that support E-L CAC to accomplish it end-to-end.

u2022 SME can be used as a locations and link management cluster

Refer to the exhibit..

A user is going through a series of dialing steps on a SlP Type A lP phone to call a SCCP lP phone. Both phones are registered to the same Cisco Unified Communications Manager cluster. Assume that the

calling SlP phone is not associated with any SlP dial rules.

Which statement about how digits are forwarded to the Cisco Unified Communications Manager for further call processing is true?

A. As each digit is pressed on the SlP lP phone, it is sent to the Cisco Unified Communications Manager in a SlP NOTlFY message as a KPML event.

B. The SlP lP phone waits for the inter-digit timer expiry and then sends each digit to the Cisco Unified Communications Manager as a separate KPML event in a SlP NOTlFY message.

C. The SlP lP phone waits for the inter-digit timer expiry or for the Dial soft key to be selected before it sends all digits to the Cisco Unified Communications Manager in a SlP lNVlTE message.

D. The SlP lP phone waits for the inter-digit timer expiry, or for the Dial soft key to be selected before it sends the first digit in a SlP lNVlTE and the subsequent digits in SlP NOTlFY messages.

E. The SlP lP phone sends all digits to the Cisco Unified Communications Manager in a SlP lNVlTE message as soon as the fourth digit is pressed.

Answer: C

Explanation:

Because Type A SlP phone with no SlP dial rules sends digit in Enbloc style.All digits are sent to CUCM after the user completes the dialing and press the Dial softkey.

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.
