The purpose of this chapter

For Chapters 1–4, the content should remain relevant throughout the life of this edition. But for this chapter, we will update the content over time. Even after you purchase the book, you’ll be able to access a PDF file online with the most up-to-date version of this chapter.

Why do we need to update this chapter after the publication of this book? For these reasons:

• To add more technical content to the book before the next edition is published. This updated PDF chapter will include additional technology content.
• To communicate detail about the next version of the exam, to tell you about our publishing plans for that version, and to help you understand what that means to you.
• To provide an accurate mapping of the current exam objectives to the existing chapter content. Though exam objectives evolve and products are renamed, most of the content in this book will remain accurate and relevant. The online chapter will cover the content of any new objectives, as well as provide explanatory notes on how the new objectives map to the current text.

After the initial publication of this book, Microsoft Press will provide supplemental updates as digital downloads for minor exam updates. If an exam has major changes or accumulates enough minor changes, we will then announce a new edition. We will do our best to provide any updates to you free of charge before we release a new edition. However, if the updates are significant enough in between editions, we may release the updates as a low-priced stand-alone e-book.

If we do produce a free updated version of this chapter, you can access it on the book’s product page, simply visit MicrosoftPressStore.com/ERDP9002e/downloads to view and download the updated material.
