Azure governance relies on a clear structure to manage resources effectively. You’ll need to understand that.
And this image here outlines the four key layers. So understand the structure for those layers.
Management groups -> Subscription -> Resource groups -> Resources
Remember that hierarchy as part of your exam. Know that within each subscription resource groups organize related services such as resources like virtual machines and databases and storage accounts which makes it easier to manage.
At the bottom level you have your resources which are all the key components that you deploy. Virtual machines. Databases. Storage accounts and so forth. Understand tagging and understand a strong tagging strategy. This is going to be important also. And keep in mind that they’re especially useful in large environments where visibility and control are crucial. Understanding how these layers interact and how to apply policies, manage access, and use tags effectively is essential for designing an environment and preparing for your exam.
