Cisco certification exam topics can facilitate your certification pursuit in two important ways:
They show, by means of a percentage, the amount of focus, or weight, given to each general topic, or domain, in an exam. Knowing the percentages will allow you to allocate study and test-taking time more strategically. They provide additional detail about each domain by means of subtopics, which will give you a clearer sense of exam coverage upfront.
