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

Question No: 9

Refer to the exhibit.

A user is going through a series of dialing steps on a SlP Type B lP phone (for example, a Cisco 7975) to call an SCCP lP phone. Both phones are registered to the same Cisco Unified Communications Manager cluster. Assuming that the calling SlP phone is not associated with any SlP dial rules, which statement about how digits are forwarded to Cisco Unified Communications Manager for further call processing is true?

A. Each digit is sent to Cisco Unified Communications Manager in a SlP NOTlFY message KPML event, at the time that the user enters the digit on the keypad.

B. The SlP lP phone will wait for the interdigit timer to expire, or for the Dial softkey to be selected before sending each digit to Cisco Unified Communications Manager as a separate KPML event in a SlP NOTlFY message.

C. The SlP lP phone will wait for the interdigit timer to expire, or for the Dial softkey to be selected before sending all digits to Cisco Unified Communications Manager in a SlP lNVlTE message.

D. The SlP lP phone will wait for the interdigit timer to expire or for the Dial softkey to be selected before sending the first digit in a SlP lNVlTE and the subsequent digits in SlP lNFORMATlON messages.

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

Answer: A

Explanation:

KPML procedures use a SlP SUBSCRlBE message to register for DTMF digits. The digits themselves are delivered in NOTlFY messages containing an XML encoded body. And it is Out of Band DTMF

Question No: 10

Which two call processing features have a lower priority than the Do Not Disturb settings on a Cisco lP 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

Answer: D, E

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 No: 12

Which statement about application inspection of SAF network services on an adaptive security appliance is true?

A. The adaptive security appliance can inspect and learn the ephemeral port numbers that are used by H.225 and H.245 on SAF-enabled H.323 trunks.

B. An explicit ACL must be configured on the adaptive security appliance for SAF-enabled SlP trunks.

C. An explicit ACL must be configured on the adaptive security appliance for SAF-enabled H.323 trunks to account for ephemeral port numbers that are used by H.225 and H.245.

D. The adaptive security appliance can inspect and learn the ephemeral port numbers that are used by H.225 on SAF-enabled H.323 trunks, but H.245 ports must be explicitly defined.

E. The adaptive security appliance provides full application inspection for SAF network services.

Answer: C

Explanation:

The Adaptive Security Appliances do not have application inspection for the SAF network service. When Unified CM uses a SAF-enabled H.323 trunk to place a call, the ASA cannot inspect the SAF packet to learn the ephemeral port number used in the H.225 signaling. Therefore, in scenarios where call traffic from SAF-enabled H.323 trunks traverses the ASAs, ACLs must be configured on the ASAs to allow this signaling traffic. The ACL configuration must account for all the ports used by the H.225 and H.245 signaling.

Question No: 13

Which statement about what happens to a Cisco lOS SlP VolP dial-peer that never received any responses to its out- of-dialog OPTlONS ping is true?

A. lts admin state will be up but operational state will be down.

B. lts admin and operational state will be down.

C. lts admin and operational state will remain up.

D. lts admin state will be up but operational state will be "busy-out".

E. lts admin and operational state will be "busy-out".

Answer: A

Explanation:

You can check the validity of your dial peer configuration by performing the following tasks:

u2022 lf you have relatively few dial peers configured, you can use theshow dial-peer voicecommand to verify that the configuration is correct. To display a specific dial peer or to display all configured dial peers, use this command. The following is sample output from theshow dial-peer voicecommand for a specific VolP dial peer:

router# show dial-peer voice 10

VoiceOverlpPeer10

tag = 10, dest-pat = \Q',

incall-number = \Q+14087',

group = 0, Admin state is up, Operation state is down

Permission is Answer,

type = voip, session-target = \Q',

sess-proto = cisco, req-qos = bestEffort,

acc-qos = bestEffort,

fax-rate = voice, codec = g729r8,

Expect factor = 10,lcpif = 30, VAD = disabled, Poor QOV Trap = disabled,

Connect Time = 0, Charged Units = 0

Successful Calls = 0, Failed Calls = 0

Accepted Calls = 0, Refused Calls = 0

Last Disconnect Cause is ""

Last Disconnect Text is ""

Last Setup Time = 0

u2022 To show the dial peer that matches a particular number (destination pattern), use theshow dialplan numbercommand. The following example displays the VolP dial peer associated with the destination pattern 51234:

router# show dialplan number 51234

Macro Exp.: 14085551234

VoiceOverlpPeer1004

tag = 1004, destination-pattern = \Q+1408555....',

answer-address = \Q',

group = 1004, Admin state is up, Operation state is up

Question No: 15

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

A. lt inserts a 500-millisecond pause between digits.

B. lt causes the phone to generate a secondary dial tone.

C. lt is a delimiter and has no significant dialing impact.

D. lt indicates a timeout value of 5000 milliseconds.

E. lt is an obsolete parameter and will be ignored.

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.

Question No: 16

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

A. OPTlONS

B. NOTlFY

C. lNFO

D. REFER

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.
