MCA Microsoft Certified Associate Azure Security Engineer Study Guide: Exam AZ-500 (Sybex Study Guide)

Covers alot of subjects. I have learned a lot from this book so I found it useful. It falls short in defining terms that it throws at you such as "app service", "hybrid connection" etc etc, so get ready to do a lot of research on your own to fully understand some of the concepts and terms that are thrown at you. I also get the sense that the book is rushing you along. Some subjects are briefly covered, but very little detail is included.
