The exam tests a series of skills. These skills are referred to as the exam's objective domain.
Being familiar with the objective domain is important to candidates for the exam. You won't see questions on all the skills listed, as the questions in a given exam are randomized from a pool of questions, and you might see questions that aren't listed as some of the skills are vague and/or could be interpreted in different ways. However, making sure you have covered everything in the objective domain will give you a much better chance of passing the exam.
The objective domain is broad, with a lot of separate topics listed. If you have taken older product-orientated exams, this might seem daunting. But for these role-based exams, you don't need to learn all the facts about each item as you had to do previously.
