Chapter 27. Exam Overview

As a network administrator or consultant, your job can involve planning, analyzing, and designing networks as much as implementing them. This may include choosing protocols and services to use, designing addressing and Internet access schemes, and providing other services, such as remote access.

MCSE Exam 70-221, Designing a Microsoft Windows 2000 Network Infrastructure, deals with the high-level design and planning of network protocols and services. This exam can be used as an optional core exam or as an elective.

There is some overlap in Microsoft’s objectives between this exam and the basic Network Infrastructure exam (Exam 70-216), which focuses more on the technical implementation of network protocols and services. You should study Part IV, as well as this chapter before taking the Designing a Microsoft Windows 2000 Network Infrastructure exam.

To prepare for this chapter and the Network Infrastructure exam, you should have studied Part IV and Part I and Part II (Windows 2000 Professional and Server). You should also have real-world experience with computers in a networked environment that uses the services and protocols covered in this chapter.
