Objective: Install and manage Office Communications Server (OCS) 2007.
Sub-objective: Determine the differences between the Standard Edition and the Enterprise Edition.
Single answer, multiple-choice
You are the network administrator for your company. You are installing Office Communications Server 2007 to provide Web-conferencing capabilities to remote users and instant messaging (IM) capabilities to internal users. This solution will support 350 users worldwide. You want to implement the most cost-effective solution.
A. Install Office Communications Server 2007 Standard Edition and deploy an Access Edge server with the Web Conferencing Edge Server role.
B. Install Office Communications Server 2007 Standard Edition and deploy a Web Conferencing server.
C. Install Office Communications Server 2007 Enterprise Edition and deploy the Web Conferencing Server role and the Access Edge Server role.
D. Install Office Communications Server 2007 Enterprise Edition, deploy an Access Edge Server with the Web Conferencing Edge Server role and utilize a reverse proxy server.
Answer:
A
Tutorial:
In this scenario, you should install Office Communications Server 2007 Standard Edition and deploy the Web Conferencing Edge Server role and the Access Edge Server role. The home server installation of the Standard Edition allows you to run the Web Conferencing and IM Conferencing Server roles on a single physical computer. You can co-deploy the Web Conferencing Edge Server role and the Access Edge Server role on a second server, making the Standard Edition a cost-effective solution.
The Enterprise Edition would require three servers to provide the same functionality because the home front-end server and database server cannot be installed on the same server; also, the Web Conferencing Server role and the IM Conferencing Server roles cannot be installed on the same server. Because you are only supporting 350 users, you do not need the scalability of the Enterprise edition.
You should not install Office Communications Server 2007 Standard Edition and deploy the Web Conferencing server role. Remote user support for Web conferencing requires a Web Conferencing Edge Server to provide data collaboration with remote users, as well as the Web Conferencing server role. Remote user Web conferencing also requires an Access Edge server to serve as a single, secure point for both inbound and outbound traffic during a Web session. If you were only supporting internal users, a Web Conferencing Edge Server would not be required.
You should not install Office Communications Server 2007 Enterprise Edition and deploy the Web Conferencing Edge Server role, the Access Edge Server role and a reverse proxy server. The Enterprise Edition is not a cost-effective solution for this scenario because the Standard Edition can support up to 5,000 users. A reverse proxy server would be required to provide remote users group expansion, address file download and the ability to download Web-conference slides.
Similarly, you should not install Office Communications Server 2007 Enterprise Edition and deploy the Web Conferencing Server role and the Access Edge Server role. The Enterprise Edition is less cost-effective than the Standard Edition; also, you will require a Web Conferencing Edge server to allow remote users to join internal Web conferences.

Multiple answer, multiple-choice
You installed Microsoft Office Communicator 2007. Which two steps are required to configure custom presence states in Office Communicator 2007? (Choose two. Each correct option represents part of the solution.)
A. Create a custom presence configuration file using the .CFG extension.
B. Create an XML custom presence configuration file.
C. Add the CustomStateURL value to the computer’s registry.
D. Set the Presence menu custom presence states using the OnSelectionChange function call.
E. Modify the Local Users and Groups preference settings using the Group Policy Administration tools.
Answer:
B and C
Tutorial:
To configure custom presence states in Office Communicator 2007, create an XML custom presence configuration file and add the CustomStateURL value to the computer’s registry. The XML file defines the custom presence states, and the registry value specifies the location of the XML file. This is an example of a custom presence state XML file:
Working on site
Out on a sales call
In a meeting - text msgs only
Urgent interruptions only
If the XML file is named custompresense.xml and is stored on a network shared named \\server\OCSShare, the registry entry would be:
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Communicator]
@=""
"CustomStateURL"="file://\\\\server\\OCSShare\\custompresense.xml"
The option to create a configuration file and save it using the .CFG extension is invalid. A configuration file will not affect custom presence messages in OCS 2007.
The option to set the Presence menu custom presence states using the OnSelectionChange function call is incorrect. The custom presence states are set using an XML file. The OnSelectionChange function is used to manipulate contextual content in custom tabs, not custom presence states.
Modifications to the Local Users and Groups settings are not required to set custom presence states.

Objective: Configure conferencing.
Sub-objective: Configure the Web Conferencing Server.
Single answer, multiple-choice
You deployed Office Communications Server 2007. You configured a Web Conferencing Edge Server to host Web conferences. Users report that they receive an error message stating the server is unavailable when they attempt to download files from the Address Book Server. What should you do to make the server available to users?
A. Enable remote user access on the Web Conferencing Edge Server.
B. Configure the Web Components Server certificate.
C. Restart the Office Communications Server 2007.
D. Start the Internet Information Services (IIS) server.
Answer:
D
Tutorial:
In this scenario, you should start the Internet Information Services (IIS) server to make the Web Components Server available. The Web Components Server enables users to download Address Book Server files. If a user is unable to access a service provided by the Web Components Server, you should check the event log for any errors or warnings.
You can then perform one of the following actions to resolve the problem based on the error message displayed to the user:
• If the user receives an error message “unauthorized 401”, check the following to allow user authorization:
o You should check that the user is enabled for Web conferencing by checking the user properties.
o You should check the configuration of the certificate for the Web Components Server.
• If the user receives a “server unavailable” error, perform the following checks:
o Verify that the IIS server is running.
o Check the Web Components Server application pool for a valid service account.
o Verify the application pool service is enabled and is running using the Service Control Manager.
You should not enable the remote user access on the Web Conferencing Edge Server in this scenario. If the user is not enabled on the Web Conferencing Edge Server, the user will receive the “unauthorized 401” error message when attempting to access a service provided by the Web Components server, not the unavailable server error. Also, users use the Web Components Server to download files from the Address Book Server, not the Web Conferencing Edge Server.
You should not configure the Web Components Server certificate in this scenario. If the Web Components Server certificate is not configured, the user will receive an unauthorized 401 error message, not the server unavailable error.
You should not restart the Office Communications Server 2007 in this scenario. Restarting Office Communication Server 2007 will not resolve the problem. Restarting the Office Communications Server 2007 is recommended if you are experiencing problems with archiving or CDR.

Objective: Configure Enterprise Voice Functionality.
Sub-objective: Configure the Mediation Server.
Single answer, multiple-choice
You deployed Office Communications Server 2007 with PBX integration and Enterprise Voice. Your organization has offices in New York and Washington. One of the six departments in the New York office is enabled for Enterprise Voice. You configured a single dial plan for the entire organization.
What should you do next?
A. Create one location profile for all users.
B. Create a separate location profile for the users enabled for Enterprise Voice.
C. Create two location profiles for each location.
D. Create one normalization rule to be used by all the location profiles.
Answer:
B
Tutorial:
You should create a separate location profile for the users enabled for Enterprise Voice. A location profile is a set of normalization rules. Normalization rules translate dialed numbers into a standard (E.164) format. One or more normalization rules must be created for each location profile. Because the normalization rules differ for users enabled for Enterprise Voice, create a separate location profile for these users.
Location profiles define how the Office Communication Server 2007 interprets and routes phone numbers. A separate location profile must be created for each of your organization’s geographic locations. If a single dial plan is maintained for your organization, a separate location profile is needed for users who are enabled for Enterprise Voice.
You should not create one location profile for all users because a separate location profile must be created for each of your organization’s geographic locations.
You should not create a normalization rule for all the location profiles because a location profile is a set of normalization rules. Normalization rules translate dialed numbers in various formats into a standard (E.164) format.

Objective: Monitor and Maintain OCS 2007.
Sub-objective: Install and configure IM archiving.
Multiple answer, multiple-choice
You deployed Office Communications Server 2007 Enterprise Edition. You are enabling archiving and installing Message Queuing. You want to receive notifications from the Archiving and CDR Server destination queue using Microsoft Message Queuing (MSMQ). What should you do? (Choose two.)
A. Install Message Queuing on each server in the pool that requires archiving.
B. Install Message Queuing on the Office Communications Server that is running the Archiving and CDR Server.
C. Install Message Queuing on the archiving backend database.
D. Install Message Queuing on the edge server.
Answer:
A and B
Tutorial:
You should install Message Queuing on each server that requires archiving and on the Office Communications Server that is running the Archiving and CDR Server. The archiving and CDR agent receives notifications from the Archiving and CDR using the Message Queuing. Message Queuing must also be installed with the Active Directory integration component.
You should not install Message Queuing on the archiving backend database. The Archiving and CDR Server writes messages to the Archiving Back-End database. Message Queuing passes the messages from the archiving and CDR agent to the Archiving and CDR Server, but does not write messages to the database server.
You should not install Message Queuing on each edge server. Edge Servers authorize and direct remote and federated users to the front-end servers, but do not handle any archiving tasks.
