- A
Azure Policy
Correct. Azure Policy enforces organizational standards and can restrict allowed VM sizes. Policies assigned to a management group apply to all subscriptions under it.
- B
Azure Blueprints
Why wrong: Incorrect. Azure Blueprints orchestrates the deployment of resources and policies together but does not automatically enforce rules on existing subscriptions unless the blueprint is assigned. Policies are a component of blueprints, but the direct enforcement service is Azure Policy.
- C
Azure Role-Based Access Control (RBAC)
Why wrong: Incorrect. RBAC manages who can access resources and what actions they can perform, but does not enforce resource configuration like VM sizes.
- D
Azure Resource Manager
Why wrong: Incorrect. Azure Resource Manager is the deployment and management service for Azure resources. It does not provide built-in policy enforcement rules.
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 has multiple Azure subscriptions. They need to enforce a rule that only specific virtual machine sizes (e.g., Standard_D2s_v3) can be used across all subscriptions. They also want this rule to automatically apply to any future subscriptions created. Which Azure service should they use?
Answer choices
Why each option matters
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 the correct service because it allows you to create, assign, and manage policies that enforce specific rules (such as allowed virtual machine SKUs) across your Azure environment. By assigning a built-in or custom policy definition (e.g., 'Allowed virtual machine SKUs') at the management group scope, the rule automatically applies to all existing and future subscriptions within that management group, ensuring consistent governance without manual intervention.
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 on resource properties) with Azure Blueprints (which packages multiple resources for deployment) or RBAC (which controls user permissions), but the question specifically requires automatic enforcement across all subscriptions, which only Azure Policy with management group assignment can achieve.
Detailed technical explanation
How to think about this question
Azure Policy uses policy definitions written in JSON (e.g., with the 'allowedValues' constraint on the 'Microsoft.Compute/virtualMachines/sku' property) and evaluates resources during create, update, and existing resource compliance scans via the Azure Policy engine. Policies can be assigned at the management group, subscription, or resource group level, and they support 'deny', 'audit', or 'modify' effects; the 'deny' effect prevents non-compliant VM sizes from being provisioned. A real-world scenario is a finance company that must enforce cost controls by restricting all subscriptions to a predefined list of cost-efficient VM sizes, ensuring no developer accidentally deploys an expensive GPU instance.
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 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.
