- A
Azure Policy with the 'Inherit a tag from the resource group if missing' effect
Correct. Azure Policy includes built-in effects (e.g., modify, append) that can automatically apply or inherit tags. The 'Inherit a tag from the resource group if missing' effect copies the resource group's tag value to resources that do not already have that tag, ensuring automatic compliance.
- B
Azure Resource Graph
Why wrong: Incorrect. Azure Resource Graph is a query service that allows you to explore and discover resources across subscriptions. It can report on which resources are missing tags, but it cannot automatically apply or enforce tag inheritance. It is a read-only tool.
- C
Azure Management Groups
Why wrong: Incorrect. Management Groups provide a hierarchical structure for organizing subscriptions and applying policies or RBAC at scale. However, they do not directly perform tag inheritance. The actual tag inheritance is achieved by assigning an Azure Policy definition to a management group or subscription scope; the management group itself is not the enforcement mechanism.
- D
Azure Tags (manual tagging feature)
Why wrong: Incorrect. While Azure Tags are key-value pairs used for metadata and cost tracking, the manual tagging feature only allows users to apply tags manually or via scripts. It does not automatically inherit tags from the resource group. The governance team needs an automated enforcement tool, which is Azure Policy.
Quick Answer
The answer is Azure Policy with the 'Inherit a tag from the resource group if missing' effect. This built-in policy automatically copies the 'CostCenter' tag value from the resource group onto any new resource created inside it, ensuring consistent tagging without manual effort or custom scripts. For the AZ-900 exam, this scenario tests your understanding of how Azure Policy enforces governance at scale, often appearing as a scenario where you must choose between Azure Policy, RBAC, or Azure Blueprints—the key trap is confusing policy with manual tagging or automation tools like Azure Automation. Remember that Azure Policy is for *enforcing* rules, not creating resources. A helpful memory tip: think "Policy Inherits Parent Tags" or simply "PIPT"—if a resource is missing a tag, Policy can pull it from the parent resource group automatically.
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 uses Azure for multiple projects. The IT governance team wants to ensure that every new Azure resource within a subscription is automatically assigned a 'CostCenter' tag based on the resource group it is created in. The team does not want to rely on users manually applying the tag. They need a built-in Azure solution that enforces this rule without custom scripts. Which Azure feature should they use?

Correct answer & explanation
Azure Policy with the 'Inherit a tag from the resource group if missing' effect
Azure Policy with the 'Inherit a tag from the resource group if missing' effect is correct because it automatically applies the 'CostCenter' tag from the resource group to any new resource created within that resource group, without requiring manual intervention or custom scripts. This built-in policy effect enforces governance rules at scale, ensuring compliance across the subscription.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Azure Policy (which enforces rules) with Azure Tags (which are just metadata) or Azure Resource Graph (which only queries), leading them to pick a manual or non-enforcing option.
Detailed technical explanation
How to think about this question
The 'Inherit a tag from the resource group if missing' policy effect uses Azure Policy's built-in definition to evaluate resources during creation or update, and if the specified tag is absent, it automatically adds the tag with the value from the parent resource group. This leverages Azure Policy's compliance engine, which runs as a background service and can trigger remediation tasks for non-compliant resources. In real-world scenarios, this ensures cost tracking for resources like VMs or storage accounts without requiring developers to remember tagging conventions.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
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 startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
