This is a video of all the exam questions I have ever asked. If you are preparing to take the CKA, or if you are taking the CKA, then this video is for you. I hope it helps!
This is the first of three videos where I discuss a module of questions from the Certified Knowledge Architect (CKA) exam. These questions provide good examples of what to expect on the exam and how to answer them. There's a ton I could say about the CKA, but in this video I keep it high level and superficially examine the exam to determine what topics will be covered in detail later on.
