462 Chapter 12: SNA Technology
Q&A
As mentioned in Chapter 1, the questions and scenarios in this book are more difficult than what
you will experience on the actual exam. The questions do not attempt to cover more breadth or
depth than the exam; however, they are designed to make sure that you know the answer. Rather
than allowing you to derive the answer from clues hidden inside the question, the questions
challenge your understanding and recall of the subject. Questions from the "Do I Know This
Already?" quiz from the beginning of the chapter are repeated here to ensure that you have
mastered this chapter's topic areas. Hopefully, these questions will help limit the number of
exam questions on which you narrow your choices to two options and then guess. Be sure to
use the CD and take the simulated exams.
The answers to these questions can be found in Appendix A.
