Caution

The goal of self-assessment is to gauge your mastery of the topics in this chapter. If you do not know the answer to a question or are only partially sure of the answer, you should mark this question wrong for purposes of the self-assessment. Giving yourself credit for an answer you correctly guess skews your self-assessment results and might provide you with a false sense of security.

The answers to the "Do I Know This Already?" quiz are found in the appendix. The suggested choices for your next step are as follows:

• 8 or less overall score Read the entire chapter. This includes the "Foundation Topics" and "Foundation Summary" sections and the "Q&A" section.

• 9 or 10 overall score If you want more review on these topics, skip to the "Foundation Summary" section and then go to the "Q&A" section. Otherwise, move on to Chapter 20, "Scaling a VPN Using IPsec with a Certificate Authority".
