QUESTION 102

When IP 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 URI 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 URI for that end user. Which option about the primary directory URI for IP phone A is true?

 

A.

bob@cisco.com

B.

bobby@cisco.com

C.

It depends on which radio button was selected next to the Directory URI entries on the Directory Configuration page.

D.

Both are primary directory URIs in a manner like a shared line for DNs.

E.

Neither are primary directory URIs for IP phone A.

QUESTION 103

Which two call processing features have a lower priority than the Do Not Disturb settings on a Cisco IP phone? (Choose two.)

 

A.

park reversion for a locally parked call

B.

hold reversion

C.

intercom

D.

pickup notification

E.

terminating side of a call back

F.

originating side of a call back

 

Correct Answer: DE

Explanation:

For the DND Ringer Off option, only visual notification gets presented to the device. For the DND Call Reject option, no notification gets presented to the device. For the terminating side of the call, Do Not Disturb overrides call back:

When the phone that terminates the call uses DND Ringer Off, the Callback Available screen will be displayed on the phone after the terminating side goes off hook and on hook.

When the phone that terminates the call has DND Call Reject enabled but the phone becomes available (goes off hook and on hook), a new screen will be presented to the originating device as “<Extension> has become available but is on DND-R”. Callback available notification will be sent only after the terminating side disables DND Call Reject.

 

 

QUESTION 104

Which configuration component in Cisco Unified Communications Manager Enhanced Location Call Admission Control is designated to participate directly in intercluster replication of location, links, and bandwidth allocation data?

 

A.

an active member of a Location Bandwidth Manager Group

B.

a member of a Location Bandwidth Manager Hub Group

C.

a standby member of a Location Bandwidth Manager Group

D.

all members of a Location Bandwidth Manager Group

E.

a shadow member of a Location Bandwidth Manager Hub Group

 

Correct Answer: B

Explanation:

A Location Bandwidth Manager (LBM) service that has been designated to participate directly in intercluster replication of fixed locations, links data, and dynamic bandwidth allocation data. LBMs assigned to an LBM hub group discover each other through their common connections and form a fully-meshed intercluster replication network. Other LBM services in a cluster with an LBM hub participate indirectly in intercluster replication through the LBM hubs in their cluster.

 

 

QUESTION 105

Refer to the exhibit. A user is going through a series of dialing steps on a SIP Type B IP phone to call a SCCP IP phone. Both phones are registered to the same Cisco Unified Communications Manager cluster. Assume that the calling SIP phone is associated with a SIP dial rule with a pattern value of “2001”. Which statement about how digits are forwarded to the Cisco Unified Communications Manager for further call processing is true?

 

clip_image002

 

A.

As each digit is pressed on the SIP IP phone, it is sent to the Cisco Unified Communications Manager in a SIP NOTIFY message as a KPML event.

B.

The SIP IP 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 SIP NOTIFY message.

C.

As soon as the user selects the Dial soft key, the SIP IP phone forwards all digits to the Cisco Unified Communications Manager in a SIP INVITE message.

D.

As soon as the Dial soft key is selected, the SIP IP phone forwards the first digit in a S
IP INVITE and the subsequent digits in SIP INFORMATION messages.

E.

The SIP IP phone waits for the inter-digit timer expiry, and then sends all digits to the Cisco Unified Communications Manager in a SIP INVITE message.

QUESTION 106

Which two statements about Cisco Unified Communications Manager mixed-mode clusters are true? (Choose two.)

 

A.

Cluster security mode configures the security capability for your standalone server or a cluster.

B.

The device security mode in the phone configuration file is set to nonsecure.

C.

The phone makes nonsecure connections with Cisco Unified Communications Manager even if the device security mode specifies authenticated or encrypted.

D.

Security-related settings other than device security mode, such as the SRST Allowed check box, get ignored.

E.

Auto-registration does not work when you configure mixed mode.

 

Correct Answer: AE

Explanation:

Cluster security mode configures the security capability for a standalone server or a cluster.

QUESTION 107

Which system location is used for intercluster Enhanced Location CAC on Cisco Unified Communications Manager?

 

A.

Hub_None

B.

Default

C.

Intercluster

D.

Phantom

E.

Shadow

 

Correct Answer: E

Explanation:

The shadow location is used to enable a SIP trunk to pass Enhanced Location CAC information such as location name and Video-Traffic-Class (discussed below), among other things, required for Enhanced Location CAC to function between clusters. In order to pass this location information across clusters, the SIP intercluster trunk (ICT) must be assigned to the “shadow” location. The shadow location cannot have a link to other locations, and therefore no bandwidth can be reserved between the shadow location and other locations. Any device other than a SIP ICT that is assigned to the shadow location will be treated as if it was associated to Hub_None. That is important to know because if a device other than a SIP ICT ends up in the shadow location, bandwidth deductions will be made from that device as if it were in Hub_None, and that could have varying effects depending on the location and links configuration.

 

 

QUESTION 108

Which Cisco Unified Communications Manager deployment model for clustering over the IP 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

 

Correct Answer: C

Explanation:

Clustering Over the IP WAN

You may deploy a single Unified CM cluster across multiple sites that are connected by an IP 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:

Local 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.

Remote 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.

QUESTION 109

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

 

A.

REGISTER

B.

NOTIFY

C.

INFO

D.

PUBLISH

E.

UPDATE

 

Correct Answer: D

Explanation:

Cisco Unified Communications Manager supports Do Not Disturb that a SIP device initiates or that a Cisco Unified Communications Manager device initiates. A DND status change gets signaled from a SIP device to Cisco Unified Communications Manager by using the SIP PUBLISH method (RFC3909). A DND status change gets signaled from a Cisco Unified Communications Manager to a SIP 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.

QUESTION 110

What does a comma accomplish when it is used in a SIP Dial Rule pattern that is associated with a Cisco 9971 IP Phone that is registered to Cisco Unified Communications Manager?

 

A.

It inserts a 500-millisecond pause between digits.

B.

It causes the phone to generate a secondary dial tone.

C.

It is a delimiter and has no significant dialing impact.

D.

It indicates a timeout value of 5000 milliseconds.

E.

It is an obsolete parameter and will be ignored.

 

Correct Answer: B

Explanation:

Comma is accepted in speed dial as delimiter and pause. Comma used to delineate dial string, FAC, CMC, and post connect digits For post connect digits, commas insert a 2 second delay Commas may be duplicated to create longer delays.
