Designing and Deploying a Messaging Infrastructure with Microsoft Exchange 2000 Server

Exam 70-225 is available as of March 30, 2001.

This document includes information on:

• Microsoft Certification
• Target Audience
• Skills Being Measured

Microsoft Certification

When you pass this exam, you achieve Microsoft Certified Professional status. You also earn credit toward the following certifications:

• Elective credit toward Microsoft Certified Systems Engineer on Microsoft Windows 2000 certification
• Elective credit toward Microsoft Certified Systems Engineer on Microsoft Windows NT 4.0 certification

Target Audience

Candidates for this exam operate in medium to very large computing environments that have 5,000 or more client computers and that use Exchange 2000 Server, Active Directory, and Internet Information Server (IIS). They have a minimum of one year of experience managing Microsoft Exchange environments that have the following characteristics:

• Multiple physical locations
• Mixed client connection protocols, such as POP3, IMAP4, MAPI, NNTP, and HTTP mail
• Internet messaging connectivity
• Connectivity to foreign mail systems
• Multiple or complex name resolution systems.

Skills Being Measured

This certification exam measures your ability to implement, administer, and troubleshoot information systems that incorporate Microsoft Exchange 2000 Server. Before taking the exam, you should be proficient in the job skills listed below.

Analyzing Business Requirements

Analyze factors that influence organizational policy requirements. Factors include planned mergers and acquisitions, and existing and planned human resources.

Analyze the existing and planned business models. Considerations include user distribution, and user mail needs and habits.

Analyze the existing and planned business security model.

Analyze the existing and planned administrative model.

Analyzing Existing and Planned Resources

Analyze existing server roles. Factors include existing and anticipated server load. Roles include mailbox server, public folder server, and bridgehead server.

Analyze existing and planned network resources. Resources include hardware, available bandwidth, network topology, and firewall configuration.

Analyze existing directory and name resolution configurations.

Analyze the impact of Exchange 2000 Server on the existing and planned network. Considerations include requirements for local authentication servers and local global catalog servers, delegation and rights assignments, bandwidth, and messaging traffic.

Analyze the existing messaging system architecture and potential changes to this architecture. Considerations include potential message routing changes, client computer access changes, administrative model changes, and changes to messaging-based applications.

Analyze existing messaging client configurations. Considerations include hardware, operating system, access methods, existing message store requirements, and existing messaging client.

Designing an Exchange 2000 Server Messaging Solution

Design an Exchange 2000 Server routing group topology.

Design an Exchange 2000 Server administrative model. Considerations include organizational unit (OU) structure, policies, administrative group placement and boundaries, permissions, and multiple stores.

Design an Exchange 2000 Server real-time collaboration solution that uses Chat Service, Instant Messaging, or both.

Plan public folder usage and implementation. Considerations include company structure, geographical structure, maintenance policies, permissions, replication, and indexing.

Design an Exchange 2000 Server security plan.

• Secure the Exchange 2000 Server infrastructure against external attacks.
• Secure the Exchange 2000 Server infrastructure against internal attacks.
• Design an authentication and encryption strategy. Considerations include user authentication and encryption requirements, such as S/MIME, KMS, IPSec, NTLM, Digest authentication, and SSL.

Plan for coexistence of Exchange 2000 Server with other messaging systems.

• Plan for coexistence with foreign mail systems, such as Notes, cc:Mail, GroupWise, MS Mail, PROFS, TAO, and SNADS.
• Plan for coexistence with Exchange Server 5.5.

Design inter-organizational connectivity and synchronization. Considerations include existing Active Directory environment, existing DNS configuration, Active Directory Connector (ADC) configuration, security permissions, and administrative permissions and delegation.

Designate and design servers. Server configurations include front end, back end, connector, client computer access, Chat Service, Instant Messaging, free/busy, virtual vs. physical, mailbox, public folder, and multiple protocol.

Plan traffic flow. Considerations include ADC computer and bridgeheads, routing group boundaries, bandwidth, directory replication, public folder replication, existing network connection, and Site Replication Service (SRS).

Design server hardware and disk configurations to achieve fault tolerance and increased performance and to provide for a backup strategy, based on server role.

Design an upgrade or migration strategy. Considerations include primary vs. non-primary connections, and use of the appropriate version of ADC.

• Design ADC connection agreements.
• Plan a migration that uses ADMT.
• Design connection agreements to support container synchronization.
• Decide direction of synchronization.

Design a strategy for mail access. Messaging clients include MAPI, IMAP4, POP3, and HTTP mail.

Designing for Fault Tolerance and Data Recovery

Design a backup solution. Considerations include planning backup scope, defining the backup schedule, media storage and rotation, and backup type.

Design a recovery solution. Considerations include recovering the entire messaging system, individual databases, and servers; re-associating user mailboxes with accounts; and designing mailbox stores to support recovery.

Design fault tolerance solutions.

Deploying an Exchange 2000 Server Messaging Solution

Deploy routing groups and foreign connectors.

Deploy administrative groups.

Plan deployments of messaging clients, such as MAPI, IMAP4, POP3, and HTTP mail. Considerations include policies and profiles, and server scaling.

Deploy an Exchange 2000 Server messaging solution in a cluster.

Diagnose and resolve coexistence problems.

• Resolve e-mail delivery problems.
• Resolve problems with foreign connections.
• Resolve address synchronization problems.
• Resolve problems with address and name resolution.

Diagnose and resolve other deployment problems.

• Resolve failed deployments that require a rollback to Exchange Server 5.5.
• Use ADClean to resolve duplicate account problems.
• Resolve permissions problems.
• Resolve problems with sending and receiving e-mail.
• Resolve security problems.
• Resolve DNS name resolution problems.
• Resolve problems involving resource limitations.
