AZ-900 Describe Azure management and governance Practice Question
This AZ-900 practice question tests your understanding of describe azure management and governance. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company wants to ensure that all new Azure resources in a subscription are automatically tagged with a 'Department' tag. Which Azure service should they use to enforce this requirement?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Azure Policy
Azure Policy is correct because it allows you to create, assign, and manage policies that enforce specific rules on your Azure resources. In this scenario, you can use a built-in or custom policy definition to require a 'Department' tag on all new resources, and Azure Policy will automatically evaluate and enforce this rule during resource creation, preventing non-compliant resources from being provisioned.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Azure Policy
Why this is correct
Azure Policy can enforce tags on resources by using built-in or custom policies that audit or require tags.

✗
Azure Blueprints
Why it's wrong here
Azure Blueprints can package policies, but for simply enforcing a tag, a single policy is more direct and simpler to manage.
✗
Azure RBAC
Why it's wrong here
Role-based access control manages permissions for users, not the enforcement of resource properties like tags.
✗
Azure Resource Lock
Why it's wrong here
Resource locks prevent accidental deletion or modification of resources, but they do not enforce tagging.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Azure Policy with Azure Blueprints, thinking Blueprints can enforce tags, but Blueprints only deploys policies as part of a blueprint definition, not enforce them independently.
Detailed technical explanation
How to think about this question
Azure Policy uses policy definitions written in JSON with conditions and effects (e.g., 'deny', 'audit', 'append') to evaluate resources. For tagging enforcement, the 'append' effect can automatically add missing tags during resource creation, while the 'deny' effect blocks creation entirely if tags are absent. Under the hood, Azure Policy evaluates resources against assigned policies at creation time and during periodic compliance scans, using the Azure Resource Manager's REST API to intercept and validate resource requests.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
