QUESTION 251

Which three services must be stopped to change the IM & Presence service default domain setting of DOMAIN.NOT.SET? (Choose three.)

 

A.

Cisco XCP Router

B.

Cisco Intercluster Sync Agent

C.

Cisco XCP Authentication Service

D.

Cisco SIP Proxy

E.

Cisco Presence Engine

F.

Cisco AXL Web service

 

Correct Answer: ADE

Explanation:

Change the Domain Value

Follow this procedure if you want to change the domain value (from one valid domain value to another valid IP proxy domain value).

This procedure is applicable if you have a DNS or non-DNS deployment.

Procedure

Step 1

Stop the Cisco SIP Proxy, Presence Engine and XCP Router services on IM and Presence

Step 2

On the publisher node, perform the following steps to configure the new domain value:

a. Select IM and Presence Administration > System > Cluster Topology.

b. In the right pane, select Settings.

c. Configure the Domain Name value with the new domain. a. Select IM and Presence Administration > System > Service Parameters, and select the Cisco SIP Proxy service.

b. Configure the Federation Routing IM and Presence FQDN with the new domain.

e. You will be prompted to confirm these configuration changes. Select OK for both prompts, and then select Save.

Step 3

set network domain <new_domain>

This CLI command invokes a reboot of the servers.

Step 4

On all nodes in the cluster, manually start the Cisco Presence Engine and Cisco XCP Router services after the reboot is complete (if required).

Step 5

Manually regenerate all certificates on each node in the cluster.

QUESTION 252

Which statement describes the external database requirement for the Cisco IM and Presence permanent group chat feature?

 

A.

All nodes in a Cisco IM and Presence cluster can share a physical external database.

B.

All nodes in a Cisco IM and Presence cluster can share a logical external database.

C.

Each node in a Cisco IM and Presence cluster must have its own physical external database.

D.

Each node in a Cisco IM and Presence cluster must have its own logical external database.

E.

An external database is not mandatory.

 

Correct Answer: D

Explanation:

When you configure an external database entry on IM and Presence, you assign the external database to a node, or nodes, in your cluster as follows:

For the Compliance feature, you require at least one external database per cluster. Depending on your deployment requirements, you can also configure a separate external database per node.

For the Permanent Group Chat feature, you require a unique external database per node. Configure and assign a unique external database for each node in your cluster.

If you deploy both the Permanent Group Chat and Compliance features on an IM and Presence node, you can assign the same external database to both features.

 

 

QUESTION 253

Which protocol does the Cisco Jabber client use, in conjunction with Cisco IM and Presence, to deliver enterprise-class instant messaging services?

 

A.

SIP

B.

CTI/QBE

C.

XMPP

D.

IRC

E.

ICQ

 

Correct Answer: C

Explanation:

Many federated IM networks communicate using an open standard, such as Jabber, that leverages the Extensible Messaging and Presence Protocol (XMPP). Networks using XMPP provide open communications with other XMPP-based networks.

 

 

QUESTION 254

Refer to the exhibit. In this high-availability Cisco IM and Presence deployment with three subclusters, the first user is assigned to server 1A; the second user is assigned to server 2A; and the third user is assigned to server 3A. Assume that the Cisco IM and Presence is set to Active/Standby mode, to which server should the fourth user be assigned?

 

clip_image002

 

A.

1A

B.

3B

C.

1B

D.

2A

E.

3A

 

Correct Answer: A

Explanation:

This deployment model provides the same level of redundancy and high availability as outlined in the “Balanced Redundant High-Availability Deployment” section in this chapter. The only difference is that users are not deployed in a balanced fashion, but rather all reside on the primary server in the subcluster, and the backup server is there as a standby option if a node failure occurs.

 

 

 

QUESTION 255

Which protocol that is used between Cisco IM and Presence and Cisco Unified Communications Manager is responsible for the exchange of phone state presence information?

 

A.

AXL/SOAP

B.

CTI/QBE

C.

SIP/SIMPLE

D.

LDAP

E.

XMPP

 

Correct Answer: C

Explanation:

To provide interoperability between communications systems, SIP is the protocol leveraged. Enterprise Presence solutions need to provide for a uniform definition of the main communication services such as IM, voice, video, e-mail, web calendaring, and so on, while SIP delivers the necessary features.

 

 

QUESTION 256

Which Cisco IM and Presence service is responsible for logging all IM traffic that passes through the IM and Presence server to an external database for IM compliance?

 

A.

Cisco Presence Engine

B.

Cisco Serviceability Reporter

C.

Cisco Sync Agent

D.

Cisco XCP Connection Manager

E.

Cisco XCP Message Archiver

 

Correct Answer: E

Explanation:

The Cisco Unified Presence XCP Message Archiver service supports the IM Compliance feature. The IM Compliance feature logs all messages sent to and from the Cisco Unified Presence server, including point-to-point messages, and messages from adhoc (temporary) and permanent chat rooms for the Chat feature. Messages are logged to an external Cisco-supported database.

 

 

QUESTION 257

Two Jabber clients are unable to pass instant messages between each other. What is the appropriate next step?

 

A.

Review XCP router logs.

B.

Open port 5060 on the firewalls between the PCs an
d the IM&P servers.

C.

Review SIP proxy logs.

D.

Review Help > Show Connection Status in each Jabber client, and pull logs as necessary.

 

Correct Answer: A

Explanation:

The XCP Router is the core communication functionality on the Cisco Unified Presence server. It provides XMPP-based routing functionality on Cisco Unified Presence; it routes XMPP data to the other active XCP services on Cisco Unified Presence, and it accesses SDNS to allow the system to route XMPP data to Cisco Unified Presence users. The XCP router manages XMPP sessions for users, and routes XMPP messages to and from these sessions.

 

 

QUESTION 258

Which two enterprise presence domains can federate with Cisco IM and Presence by using SIP? (Choose two.)

 

A.

AOL

B.

Microsoft OCS

C.

IBM Sametime

D.

Cisco WebEx Connect

E.

Google Talk

F.

Cisco Unified Presence 8.X Releases

 

Correct Answer: AB
