📖 What is Azure CLI?
Azure CLI is a command-line tool for managing Azure resources. It enables administrators and developers to automate tasks, create scripts, and manage Azure environments using command-line commands, offering a programmatic interface to Azure services.
"While the exam primarily focuses on conceptual understanding, recognize the Azure CLI’s role in automation. Understand it provides an alternative to the Azure Portal for resource management. Exam questions may contrast CLI-based management with GUI-based management, emphasizing scripting and automation benefits."

🔑 What are the Key Concepts of Azure CLI?
- ▸ Azure CLI provides a text-based interface for managing Azure, offering automation capabilities not easily achieved through the Azure portal.
- ▸ Commands are organized into groups reflecting Azure services (e.g., `az vm`, `az storage`), simplifying resource management and discovery.
- ▸ Azure CLI supports scripting languages like PowerShell and Bash, enabling complex automation workflows and infrastructure-as-code practices.
- ▸ Authentication is crucial; the CLI uses Azure Active Directory for identity and access management, requiring appropriate permissions.
- ▸ It's a cross-platform tool, functioning on Windows, macOS, and Linux, providing consistent management across different operating systems.
🎯 How does Azure CLI appear on the AZ-900 Exam?
You may be asked to identify the benefit of using Azure CLI over the Azure portal when deploying a large number of identical virtual machines.
A scenario might describe a requirement to automate the daily backup of Azure SQL databases – determine which tool is best suited for this task.
Expect questions about how to authenticate to Azure using the CLI, including service principals and managed identities.
❓ Frequently Asked Questions
Can I use Azure CLI to manage resources in a different Azure subscription?
Yes, you can switch between subscriptions using `az account set --subscription <subscription_id>`. Ensure you have the necessary permissions in the target subscription.
Is it necessary to memorize specific Azure CLI commands for the AZ-900 exam?
No, memorization isn't the focus. Understand *when* you would use the CLI for automation and its advantages over the portal, rather than specific syntax.
How does Azure PowerShell compare to Azure CLI?
Both achieve similar results, but Azure CLI uses cross-platform commands, while Azure PowerShell is Windows-centric and uses cmdlets. Choose based on your scripting preference and OS.
