- A
Assign the policies and role at each subscription level individually.
Why wrong: This option is possible but not efficient because it requires repeating the same assignments across five subscriptions, increasing administrative overhead and potential for inconsistencies.
- B
Create a resource group in each subscription and assign policies and roles at the resource group level.
Why wrong: Resource groups exist within a single subscription and cannot span subscriptions. This approach would not apply assignments to all subscriptions from a single point; you would still need to manage each subscription separately.
- C
Place all subscriptions under a single management group and assign policies and roles at that management group level.
A management group can contain multiple subscriptions. Assignments made at the management group level are inherited by all subscriptions within it, providing a single, centralized scope for enforcement. This minimizes administrative overhead.
- D
Create an Azure Blueprint definition and apply it to each subscription separately.
Why wrong: Azure Blueprints are designed for orchestrating the deployment of resource templates, policies, and role assignments. However, to apply a blueprint to multiple subscriptions, you must create a separate blueprint assignment for each subscription, which creates more overhead than using a management group.
Quick Answer
The answer is to place all subscriptions under a single management group and assign policies and roles at that group level. This works because management groups create a hierarchical scope above subscriptions, allowing you to apply Azure Policy and RBAC assignments centrally; any policy or role set at the management group level is automatically inherited by all child subscriptions, which eliminates the need for repetitive per-subscription configurations. On the AZ-900 exam, this scenario tests your understanding of how management groups enable centralized governance across multiple subscriptions, and a common trap is to mistakenly choose Azure Policy itself or a single subscription as the scope—remember that management groups are the container that aggregates subscriptions for bulk assignments. A useful memory tip: think of a management group as a “master folder” for subscriptions—set rules once in the folder, and every file inside follows them.
AZ-900 Describe Azure architecture and services Practice Question
This AZ-900 practice question tests your understanding of describe azure architecture and services. 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 five Azure subscriptions, each managed by a different department. The IT governance team needs to enforce a single set of compliance policies (e.g., allowed VM SKUs) and assign a specific role to a central security team across all subscriptions. The goal is to minimize administrative overhead. Which Azure component should the governance team use as the scope for these assignments?

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
Place all subscriptions under a single management group and assign policies and roles at that management group level.
Management groups provide a hierarchical scope above subscriptions, enabling centralized governance. By placing all five subscriptions under a single management group, the IT governance team can assign Azure Policy definitions (e.g., allowed VM SKUs) and role-based access control (RBAC) roles (e.g., for the security team) once at that management group level. This inheritance automatically applies the policies and roles to all child subscriptions, minimizing administrative overhead compared to per-subscription or per-resource-group assignments.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Assign the policies and role at each subscription level individually.
Why it's wrong here
This option is possible but not efficient because it requires repeating the same assignments across five subscriptions, increasing administrative overhead and potential for inconsistencies.
- ✗
Create a resource group in each subscription and assign policies and roles at the resource group level.
Why it's wrong here
Resource groups exist within a single subscription and cannot span subscriptions. This approach would not apply assignments to all subscriptions from a single point; you would still need to manage each subscription separately.
- ✓
Place all subscriptions under a single management group and assign policies and roles at that management group level.
Why this is correct
A management group can contain multiple subscriptions. Assignments made at the management group level are inherited by all subscriptions within it, providing a single, centralized scope for enforcement. This minimizes administrative overhead.
Clue confirmation
The clue word "minimum / minimize" in the question point toward this answer.

Why it's wrong here

However, to apply a blueprint to multiple subscriptions, you must create a separate blueprint assignment for each subscription, which creates more overhead than using a management group.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often think resource groups are the natural scope for governance, but management groups are designed specifically for cross-subscription policy and RBAC inheritance, making them the correct choice for minimizing overhead across multiple subscriptions.
Detailed technical explanation
How to think about this question
Azure Policy and RBAC assignments support inheritance through the management group hierarchy, which can be up to six levels deep. When a policy or role is assigned at a management group, it is inherited by all child subscriptions and resource groups unless explicitly excluded via a 'Not-Scope' parameter. This is implemented via Azure Resource Manager's policy engine, which evaluates all assignments in the hierarchy during resource creation or update, ensuring compliance without manual replication. A real-world scenario is a multi-national company using a root management group to enforce a baseline policy like 'allowed locations' across all subscriptions, while department-level management groups add more specific policies.
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.

Variation 1. A company has three Azure subscriptions: one for the engineering department, one for marketing, and one for finance. The central IT team needs to apply a common set of Azure Policy definitions (e.g., allowed locations for resources) that must be enforced across all three subscriptions. Additionally, each department manager must be able to apply custom policies that only affect their own subscription. The IT team wants to organize the subscriptions into a hierarchy where they can assign the common policy at the top level and delegate custom policy assignment at the subscription level. Which Azure feature should the IT team use to create this hierarchical structure?
medium- ✓ A.Management groups
- B.Resource groups
- C.Azure Policy
- D.Azure role-based access control (RBAC)
Why A: Management groups allow you to create a hierarchical structure of Azure subscriptions, enabling you to assign common Azure Policy definitions (like allowed locations) at a top-level management group that applies to all child subscriptions. Each department subscription can then have its own custom policy assignments, as management groups support inheritance and delegation of policy assignments across the hierarchy.
