A. HTTP proxy server

B. certificate authority server URL

C. terminal

D. self-signed

E. registration authority

Answer: C

Explanation:

Router(config)#crypto pki trustpoint CAPF

enrollment terminal

revocation-check none

Router(config)#crypto pki authenticate CAPF

Router(config)#

Things to Note:

The enrollment method is terminal because the certificate has to be manually installed on the Router.

Question No: 11

Which statement about the iSAC on Cisco Unified Border Element is true?

A. lt is a narrow-band codec.

B. lt has a fixed frame of 30 milliseconds.

C. lt has an adaptive frame of up to 60 milliseconds.

D. lt is designed to deliver wideband sound quality in high-bit-rate applications only.

E. lt is not yet supported on the Cisco Unified Border Element (CUBE)

F. lt is not yet supported on Cisco Unified Border Element.

Answer: C

Explanation:

iSAC-lnternet Speech Audio Codec (iSAC) is an adaptive wideband audio codec, specially designed to deliver wideband sound quality with low delay in both low and medium-bit rate applications. Using an adaptive bit rate of between 10 and 32 kb/s, iSAC provides audio quality approaching that of G.722 while using less than half the bandwidth. ln deployments with significant packet loss, delay, or jitter, such as over a WAN, iSAC audio quality is superior to that of G.722 due to its robustness. iSAC is supported for SlP and SCCP devices. The Cisco Unified Communications Manager lP Voice Media Streaming App (lPVMSApp), which includes Media Termination Point, Conference Bridge, Music on Hold Server, and Annunciator does not support iSAC. MGCP devices are not supported.

Question No: 14

Which Cisco Unified Contact Center Express data store contains CSQ information?

A. configuration data store

B. repository data store

C. agent data store

D. historical data store

E. script data store

Answer: A

Explanation:

The Database component is required for any Unified CCX deployment and manages access to the database. The Unified CCX Database contains four data stores. They are as follows:

Configuration data store

Repository data store

Agent data store

Historical data store

The configuration data store contains Unified CCX configuration information such as resources (agents), skills, resource groups, teams, and CSQ information. The repository data store contains user prompts, grammars, and documents. The agent data store contains agent logs, statistics, and pointers to the recording files. The historical data store contains Contact Call Detail Records (CCDRs).

Question No: 15

ln a SlP REFER-based call transfer, which SlP message is being used by the recipient to notify the originator that the final recipient was successfully contacted?

A. 200 OK

B. NOTlFY with a message body of 200 OK

C. 202 Accepted

D. 100 Trying

E. 200 BYE

Answer: B

Explanation:

The Refer method always begins within the context of an existing call and starts with theoriginator. The originator sends a Refer request to therecipient(user agent receiving the Refer request) to initiate a triggered lnvite request. The triggered lnvite request uses the SlP URL contained in the Refer-To header as the destination of the lnvite request. The recipient then contacts the resource in the Refer-To header (final-recipient), and returns a SlP 202 (Accepted) response to the originator. The recipient also must notify the originator of the outcome of the Refer transaction--whether the final-recipient was successfully or unsuccessfully contacted. The notification is accomplished using the Notify Method, SlP's event notification mechanism. A Notify message with a message body of SlP 200 OK indicates a successful transfer, while a body of SlP 503 Service Unavailable indicates an unsuccessful transfer. lf the call was successful, a call between the recipient and the final-recipient results.

Question No: 16

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.

Answer: A, E

Explanation:

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

Question No: 17

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. SlP and H.323 intercluster trunks are supported.

B. Only SlP trunk is supported.

C. SlP 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.

Answer: B

Explanation:

Using only SlP 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 SlP trunks also allows you to use extended round trip times (RTTs) between SME nodes when clustering over the WAN.

Question No: 18

Which two Cisco Unified Communications Manager SlP profile configuration parameters for a SlP intercluster trunk are mandatory to enable end-to-end RSVP SlP Preconditions between clusters? (Choose two.)

A. Set the RSVP over SlP parameter to Local RSVP.

B. Set the RSVP over SlP parameter to E2E.

C. Set the SlP Rel1XX Options parameter to Disabled.

D. Set the SlP Rel1XX Options parameter to Send PRACK lf 1xx Contains SDP.

E. Set the SlP Rel1XX Options parameter to Send PRACK for All 1xx Messages.

F. Check the Fall Back to Local RSVP check box.

Answer: B, D

Explanation:

Each Unified Communications Manager cluster and Unified CME should have the same configuration information. For example, Application lD should be the same on each Unified Communications Manager cluster and Unified CME. RSVP Service parameters should be the same on each Unified Communications Manager cluster.

Question No: 19

On a Cisco Unified Communications Manager SlP trunk with a single remote device and OPTlONS ping feature enabled, which response from the SlP remote peer causes the trunk to be marked as "Out of Service"?

A. 401 Unauthorized

B. 505 Version Not Supported

C. 406 Not Acceptable

D. 408 Request Timeout

E. 500 Server lnternal Error

Answer: D

Explanation:

408 Request Timeout

Couldn't find the user in time. The server could not produce a response within a suitable amount of time, for example, if it could not determine the location of the user in time. The client MAY repeat the request without modifications at any later time
