Review

The following review questions can help you determine if you have sufficiently familiarized yourself with the material covered in this chapter. You can find the answers to these questions at the end of this book in Appendix A, "Questions and Answers."

1. What are the main advantages of FE/BE configurations?
2. You plan to support 40,000 users by means of a central arrangement of FE servers. All of the users use Outlook 2000 and the Microsoft Exchange Server transport service to access mailboxes and public folders. How do you need to configure the FE servers to support these users?
3. You are designing an FE/BE environment for 10,000 IMAP4 users. You plan to provide all required services for message sending and retrieval directly on the FE systems. Which messaging-related services do you need to run on the FE servers?
4. You are a messaging consultant hired to establish a hosted Exchange 2000 organization for an ASP that plans to support three independent companies through virtual organizations. Administrators within these companies are supposed to manage their own user accounts and mailbox settings. How do you need to configure the ASP’s Active Directory environment to achieve the desired functionality?
5. To support independent companies in an Exchange 2000 environment you need to assign the users correct and company-specific SMTP addresses and split the GAL accordingly. How can you achieve this in a single Exchange 2000 organization?
6. You have deployed two IM routers in a load-balancing cluster to provide reliable IM services to your users. Users do not communicate with external organizations. How do you need to configure the DNS environment to allow your users to log on to Instant Messaging using their SMTP addresses?
7. You have deployed three IM routers and five IM home servers in your environment. Direct communication via HTTP and RVP is possible over the computer network, but your users are unable to log on to Instant Messaging using the MSN Messenger client. What do you have to configure to allow your users to participate in IM?
8. Your users want to exchange instant messages over the Internet with users in partner organizations. To protect your internal network and control the outgoing communication, you have implemented a DMZ containing several Web proxies in a load-balancing cluster. What do you have to configure in Instant Messaging to support the desired form of communication?
