Foreword
described to help you see the relationships between devices, IP addressing schemes,and so forth.■
When appropriate, review the answers you weren’t sure of. However, you shouldonly change your answer if you’re sure that your original answer was incorrect.Experience has shown that more often than not, when test-takers start second-guessing their answers, they end up changing correct answers to the incorrect.Don’t “read into” the question (that is, don’t fill in or assume information that isn’tthere); this is a frequent cause of incorrect responses.■
As you go through this book, pay special attention to the Exam Warnings, as thesehighlight concepts that are likely to be tested.You may find it useful to go throughand copy these into a notebook (remembering that writing something down rein-forces your ability to remember it) and/or go through and review the ExamWarnings in each chapter just prior to taking the exam.■
Use as many little mnemonic tricks as possible to help you remember facts andconcepts. For example, to remember which of the two IPSec protocols (AH andESP) encrypts data for confidentiality, you can associate the “E” in encryption withthe “E” in ESP.Pedagogical Elements

Exam Warning These focus on specific elements on which the reader needs tofocus in order to pass the exam (for example, “Be sure you know the differencebetween symmetric and asymmetric encryption”).■
Test Day Tip These are short tips that will help you in organizing and remem-bering information for the exam (for example, “When preparing for the exam ontest day, it may be helpful to have a sheet with definitions of these abbreviationsand acronyms handy for a quick last-minute review”).■
Configuring & Implementing These are sidebars that contain backgroundinformation that goes beyond what you need to know from the exam, but providea “deep” foundation for understanding the concepts discussed in the text.■
