Exam Highlights

Before taking the exam, review the key points and terms that are presented in this chapter. Return to the lessons for additional practice.

Key Points

• You need Exchange Server 2003, Enterprise Edition, to implement the Microsoft Cluster Service. However, you can implement the Network Load Balancing service. The Microsoft Cluster Service is for failover protection and does not provide load balancing.

• The Default HTTP virtual server is called the Exchange virtual server and must be configured using IIS Manager rather than Exchange System Manager. POP3 and IMAP4 do not send e-mail; SMTP is used for this purpose. HTTP virtual servers support WebDAV and OWA. There is not a specific WebDAV or OWA virtual server.

• Unless you encrypt the entire TCP/IP session using SSL or TLS, using basic authentication will transmit passwords over a network in clear text. You can control client access by IP address, subnet, or domain name, or by using authentication.

• POP3 manages e-mail on the client. IMAP4 manages it on the server. IMAP4 supports fast message retrieval, but does not support uuencode or BinHex for MacIntosh. SMTP virtual servers can be configured to relay mail for IMAP4 and POP3 clients.
