1.	What is the default port configuration of a POP3, an IMAP4, and an NNTP virtual server?
2.	Which protocol services associated with Exchange Server 2003 virtual servers are disabled by default?
3.	The default HTTP virtual server is known as the Exchange virtual server. What additional feature distinguishes it from all other virtual servers?

Answers

1.	Incoming POP3 connections use TCP port 110, and POP3 SSL connections use port 995. Incoming IMAP4 connections use TCP port 143, and SSL connections use port 993. Incoming NNTP connections use TCP port 119, and SSL connections use port 563.
2.	The NNTP service, the Exchange POP3 service, and the Exchange IMAP4 service.
3.	It is configured using IIS Manager rather than Exchange System Manager.

Lesson 2 Review

What function do virtual servers on front-end Exchange Server 2003 servers perform, and what function do virtual servers on back-end Exchange Server 2003 servers perform? What do you need to install on each back-end server to handle front-end requests?

How does the implementation of the connection time-out setting differ between server roles?

You want to limit access to a virtual server. You want to ensure that only hosts with IP addresses 10.0.10.129 through 10.0.10.191 can access the server. You click the Access tab of the virtual server's Property box and then click Connection. Then you select Only The List Below. What parameters do you add?

Network address 10.0.10.129, subnet mask 255.255.255.192
Network address 10.0.10.128, subnet mask 255.255.255.192
Network address 10.0.10.129, subnet mask 255.255.255.128
Network address 10.0.10.128, subnet mask 255.255.255.128

Answers

1.	Internet protocol virtual servers on front-end Exchange Server 2003 servers handle incoming client connections, while the back-end virtual servers are dedicated to running the databases. You need to create a virtual HTTP server on each back-end server to handle front-end requests.
2.	On back-end servers, the connection time-out setting limits the length of time for which a client is permitted to remain connected to the server without performing any activity. On front-end servers, the connection time-out setting limits the total length of the client's session, regardless of client activity.
3.	The correct answer is b.

What symbol indicates that a virtual server is stopped, and what symbol indicates that it is paused?

When would you pause a virtual server rather than stopping it?

What diagnostic logging level logs high-level events by logging a single entry for each major task performed by the service?

None
Minimum
Medium
Maximum

Answers

1.	If the virtual server is stopped, the console displays a red circle with a white X inside it. If the virtual server is paused, the console displays a white circle with two black bars inside it.
2.	When you do not want to disconnect current user sessions but want to prevent any more users from connecting.
3.	The correct answer is b.

Case Scenario Exercise: Requirement 1

Page 9-55

1.	Management requires assurance that confidential collaboration information is not made available to casual browsers and the general public. How do you set up your Exchange Server 2003 organization to meet this concern?
2.	You have delegated the task of configuring the Exchange virtual server to an assistant administrator. You have configured all the appropriate rights and permissions. Your assistant reports that when she attempts to configure HTTP virtual servers (particularly the Exchange virtual server) using Exchange System Manager, most of the controls she wants are dimmed. What do you tell her?

Answers

Although you can meet the HTTP requirements by implementing a secure virtual directory for WebDAV collaboration, Management will probably be more at ease if you create an additional HTTP virtual server. You can allow anonymous access to the virtual server that manages your company Web site, and configure filtering, authentication, and encryption on the virtual server that manages the WebDAV collaboration.

The Exchange virtual server, or the Default HTTP virtual server, is administered using the IIS Manager console, not the Exchange System Manager console.

Case Scenario Exercise: Requirement 2

1.	Your assistant has configured the timeout settings on the POP3 virtual servers on your front-end Exchange Server 2003 servers. Users complain that connections are timing out before they can download large attachments. What is the most likely reason for this?
2.	Some of your users who log on to Apple Macintosh computers report difficulties in reading e-mails. What is the most likely reason for this problem?

Answers

1.	This setting on a back-end server will cause a timeout after a period of inactivity. On a front-end server, the same setting causes a timeout whether there has been activity or not. It is possible that your assistant has used the same setting on back-end and front-end servers.
2.	Macintosh clients understand uuencode and BinHex for Macintosh. If a POP3 client uses uuencode rather than Multipurpose Internet Mail Extensions (MIME), and requires BinHex for Macintosh, then you or your assistant needs to configure this type of encoding for those clients. This could involve either creating an additional POP3 virtual server or setting per-client options.

Case Scenario Exercise: Requirement 3

Users logged on to IMAP4 clients in Coho Winery report poor e-mail performance. Users on other clients are not experiencing the same problems. You inspect the Application log on Event Viewer, but there is insufficient detail for you to diagnose the problem. You decide that you need to monitor IMAPSvc events more closely. In particular, you need more detail when a fault occurs. How do you meet this requirement?

Answers

1.	You need to increase your diagnostic logging level. You do this by using the application log in Event Viewer to view the logs. You use Exchange System Manager to change the diagnostic logging level.
