At the end of this book, we will provide sample questions so that you can get familiar with the general structure of the exam questions and to provide guidance on determining the information that's vital to answer the questions correctly. For example, a question will start off with a detailed description of the company's size, the number of branch offices, and number of users, and will then lay out the requirements, such as the requirements for authentication from a centralized directory, requirements for connecting the branch offices like bandwidth or amount of data being transferred, and so on. Sometimes, it will take a bit of simple math, such as dividing the number of hours in a backup window with the throughput of the device provided in the question, and so on. We will also point out the explanation for the answers to the questions by providing excerpts from and links to the AWS documentation.
