1.1 Introducing the CKA Exam
Welcome to Acing the Certified Kubernetes Administrator Exam. If you’ve purchased this book, chances are you’ve already researched the exam, know what it’s about and perhaps even have it on your schedule. If not, don’t worry, we’ll talk about what the exam is and how to get signed up as soon as possible.
