“Do I Know This Already?” Quiz–Cisco Configuring a Network
Take the quiz (either here or use the PTP software) if you want to use the score to help you decide how much time to spend on this chapter. Appendix A, “Answers to the ‘Do I Know This Already?’ Quizzes,” found at the end of the book, includes both the answers and explanations. You can also find answers in the PTP testing software.

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 that question as wrong for purposes of the self-assessment.
Giving yourself credit for an answer you incorrectly guess skews your self-assessment results and might provide you with a false sense of security.
