Earlier editions of this book included some open-ended questions to help readers prepare for the exam. Open-ended questions help you prepare by giving fewer clues about the correct answers, requiring you to exercise your memory and apply mental processes to find the right answers. Although these questions can be effective, multiple-choice and simulation questions in the exam engine that use more detailed questions, exhibits, and longer explanations can provide many of the same benefits of open-ended questions. The advantage is you will know whether your answer was graded correct or incorrect—an inherent difficultly with the answers to open-ended questions.
This edition of CCNA ICND2 640-816 Official Cert Guide does not include open-ended questions as one of the core study tools. However, because surveys show that a small percentage of readers would like access to open-ended questions, the questions from earlier editions have been listed here for your reference. Note that no new questions have been added for this edition compared to earlier editions.
