Question-Handling Strategies

For those questions that have only one right answer, usually two or three of the answers are obviously incorrect, and two of the answers are plausible. Unless the answer leaps out at you (if it does, reread the question to look for a trick; sometimes those are the ones you're most likely to get wrong), begin the process of answering by eliminating those answers that are most obviously wrong.

At least one answer out of the possible choices for a question can usually 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.

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 among 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.

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

Numerous questions assume that the default behavior of a particular utility is in effect. If you know the defaults and understand what they mean, this knowledge will help you cut through many Gordian knots. Simple "final" actions may be critical as well. If a utility must be restarted before proposed changes take effect, a correct answer may require this step as well.
