Solution

1. Step 1: Understand Azure CLI functionality

   Azure CLI is designed to let users manage Azure cloud resources easily from their local machine.

2. Step 2: Compare options with purpose

   Only To manage Azure resources from your computer correctly describes this purpose; others describe unrelated tasks.

3. Final Answer:

   To manage Azure resources from your computer -> Option A

4. Quick Check:

   Azure CLI = Manage Azure resources [OK]

Hint: Azure CLI is for managing Azure, not coding or speed tests [OK]

Common Mistakes:

3. Step 3: Evaluate other options

   A skips login which fails commands, B requires manual input, D still opens browser.
