Why practice questions are the fastest way in
Reading about the cloud and answering exam questions about it are two different skills, and only one of them is tested. The CLF-C02 rarely asks you to recall a definition; it asks you to pick the best of several options that all sound reasonable. That skill only develops by working through questions and understanding why the other options fail.
That is why every page in this cluster hands you the questions first, with the reasoning attached. Start with the domain that carries the most weight in the exam, or with the one you are least sure about — the pages below are grouped so you can pick either way.
