A Self Test Software Practice Test

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.
