Skills Being MeasuredThis
exam measures your ability to accomplish the technical tasks listed
below.The percentages
indicate the relative weight of each major topic area on the exam.The
higher the percentage, the more questions you are likely to see on that
content area on the exam.
The information after “This objective
may include but is not limited to” is intended to further define or
scope the objective by describing the types of skills and topics that
may be tested for the objective. However, it is not an exhaustive list
of skills and topics that could be included on the exam for a given
skill area. You may be tested on other skills and topics related to the
objective that are not explicitly listed here.
