For questions that have only one right answer,
usually two or three of the answers will be obviously incorrect,
and two of the answers will be plausible. Unless the answer leaps
out at you (if it does, reread the question to look for a
tricksometimes 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. You should 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
correct answers, reread the question. Try
to picture how each of the possible remaining answers would alter
the situation. Be
sensitive to terminology; sometimes
the choice of words (
) 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 getting a question right; just don't be too
hasty when making a blind guess.
If you're taking a fixed-length or a short-form
test, you can wait until the last round of reviewing
questions (just as you're about to run out of time or unanswered
questions) before you start making guesses. You will usually have
the same option within each case study testlet (but once you leave
a testlet, you might not be allowed to return to it). If you're
taking an adaptive test, you'll have to guess to move on to the
question if you can't figure out an answer some other way.
Either way, guessing should be your technique of last resort!
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 of the trickier questions. Simple final
actions can be critical as well. If a utility must be restarted
before proposed changes take effect, a correct answer might require
this step as well.
