To become an Azure Administrator, you need to have the following skills:
- Should know how to administrate the Vms such as deploying, configuring, backing up VMs
- Should take care of tasks like securing the data, backing up the data stored on the cloud
- Capable to handle virtual networks and other networking tasks
- Learn how to encrypt the data, protect Azure AD and Azure resources
In addition to all these skills, a Microsoft Azure Administrator certificate is most important to become an Azure Administrator. For that, you need to clear an AZ 103 exam.
If you want to pass this AZ 103 exam, I would recommend this course on Azure training by Intellipaat.
