A well-known principle when taking certification exams is to first read over the entire exam from start to finish while answering only those questions you feel absolutely sure of. The next time around, you can delve into the more complex questions. Knowing how many such questions you have left helps you spend your exam time wisely. Although this is good overall testing advice, this capability is not available to you on the Support exam 642-831. To protect the integrity of the certifications, Cisco does not allow you to mark and go back to review a previously answered question.
The most important advice about taking any exam is this: Read each question carefully . Some questions are deliberately ambiguous, some use double negatives , and others use terminology in incredibly precise ways. The authors have taken numerous exams ”both practice and live ”and in nearly every one have missed at least one question because they didn't read it closely or carefully enough. Here are some suggestions on how to deal with the tendency to jump to an answer too quickly:
Above all, try to deal with each question by thinking through what you know about supporting and troubleshooting networks. Use the OSI reference model and your knowledge of middle- and lower-layer protocols that are where a majority of your questions will come from. By reviewing what you know (and what you have written down on your information sheet), you will often recall or understand enough to be able to deduce the answer to the question. |
