Choosing the Correct Answers

Obviously, the only way to pass any exam is to select enough of the right answers to obtain a passing score. However, Cisco's exams are not standardized like the SAT and GRE exams; they are far more convoluted. In some cases, questions are strangely worded, and deciphering them can be a real challenge. In those cases, you may need to rely on answer- elimination skills. Almost always, at least one answer out of the possible choices for a question can be eliminated immediately because it matches one of these conditions:

• The answer does not apply to the situation.

• The answer describes a nonexistent issue, an invalid option, or an imaginary state.

• The answer may be eliminated because of information in the question itself.

After you eliminate all answers that are obviously wrong, you can apply your retained knowledge to eliminate further answers. Look for items that sound correct but refer to actions, commands, or features that are not present or not available in the situation that the question describes.

If you're still faced with a blind guess between two or more potentially correct answers, reread the question. Try to picture how each of the possible remaining answers would alter the situation. Be especially sensitive to terminology ; sometimes the choice of words ("remove" instead of "disable") can make the difference between a right answer and a wrong one.

Only when you've exhausted your ability to eliminate answers but remain unclear about which of the remaining possibilities is correct should you guess at an answer. An unanswered question offers you no points, but guessing gives you at least some chance of getting a question right; just don't be too hasty when making a blind guess.

Tips for Success

Chapter 1 includes a wealth of information to help you prepare for the exam. You may want to reread that chapter before proceeding with this practice exam. But for now, keep these tips in mind:

• Questions often give away their answers, but you have to be Sherlock Holmes to see the clues. Often, subtle hints appear in the question text in such a way that they seem almost irrelevant to the situation. You must realize that each question is a test unto itself and that you need to inspect and successfully navigate each question to pass the exam. Look for small clues, such as the mention of times, group permissions and names , and configuration settings.

• The test questions appear in random order, and many elements or issues that are mentioned in one question may also crop up in other questions. It's not uncommon to find that an incorrect answer to one question is the correct answer to another question, or vice versa. Take the time to read every answer to each question, even if you recognize the correct answer to a question immediately. That extra reading may spark a memory, or remind you about a Cisco troubleshooting feature or function, that helps you on another question elsewhere in the exam.

• If you see something in a question or in one of the answers that jogs your memory on a topic, or that you feel you should record if the topic appears in another question, write it down on your piece of paper. Just because you can't go back to a question in an adaptive test doesn't mean you can't take notes on what you see early in the test, in hopes that it might help you later in the test.

  

  Don't be afraid to take notes on what you see in various questions. Sometimes, what you record from one question can help you on other questions later on, especially if it's not as familiar as it should be or it reminds you of the name or use of some utility or interface details.

  
  

• Give yourself 75 minutes to take the exam, and keep yourself on the honor system--don't look at earlier text in the book or jump ahead to the answer key. When your time is up or you've finished the questions, you can check your work in Chapter 14. Pay special attention to the explanations for the incorrect answers; these can also help to reinforce your knowledge of the material. Knowing how to recognize correct answers is good, but understanding why incorrect answers are wrong can be equally valuable .

• Set a maximum time limit for questions, and watch your time on long or complex questions. If you hit your limit, it's time to guess and move on. Don't deprive yourself of the opportunity to see more questions by taking too long to puzzle over questions, unless you think you can figure out the answer. Otherwise, you're limiting your opportunities to pass.

That's it for pointers. Now, it's time to take the practice exam. Good luck!
