- A
Each subscription individually
Why wrong: Assigning the policy to each subscription individually would require many assignments and would not automatically apply to new subscriptions unless the team also updates the assignments. This is not the most efficient approach for a single, organization-wide policy.
- B
The root management group
Assigning the policy at the root management group scope applies it to all child management groups and all subscriptions within them, including any new subscriptions created in the future. This is the correct approach for a single assignment that covers the entire organization.
- C
Each child management group (Finance, HR, IT) individually
Why wrong: While assigning to each child management group would cover their respective subscriptions, it requires three separate assignments and will not automatically cover any additional management groups added later. The question specifies assigning the policy once.
- D
A single resource group
Why wrong: Assigning the policy at a resource group scope only affects resources within that specific resource group, not the subscriptions or management groups. This would not meet the requirement to restrict deployments across the entire organization.
Quick Answer
The answer is the root management group. Assigning an Azure Policy at the root management group ensures the policy is inherited by every child management group—Finance, HR, and IT—and all subscriptions within them, including any new subscriptions created in the future, because Azure Policy inheritance flows downward through the entire management group hierarchy. On the AZ-900 exam, this scenario tests your understanding of scope inheritance and the principle of minimizing administrative overhead; a common trap is choosing a child management group or individual subscription, which would fail to enforce the policy across the entire tenant. Remember that the root management group acts as the single point of enforcement for tenant-wide governance, making it the only scope that automatically covers all current and future resources. A helpful memory tip: “Root rules the whole route”—assign at the root to govern the entire tenant with one policy.
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 multinational company uses Azure management groups to organize its subscriptions. The company has a root management group (tenant root group) containing three child management groups: 'Finance', 'HR', and 'IT'. Each child management group contains multiple subscriptions. The global governance team needs to enforce an Azure Policy that restricts all resource deployments across every subscription in the organization to only the 'West US' and 'East US' regions. The policy must automatically apply to any new subscriptions that are created under any management group in the future. The team wants to assign the policy once and have it affect all current and future subscriptions with minimal administrative overhead. At which Azure scope should the team assign the policy?

Correct answer & explanation
The root management group
Assigning the policy to the root management group ensures it is inherited by all child management groups (Finance, HR, IT) and their subscriptions, including any new subscriptions created in the future. This approach enforces the allowed regions policy across the entire tenant with a single assignment, minimizing administrative overhead. Azure Policy inheritance flows from the root management group down through all levels of the hierarchy.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

- ✗
Each subscription individually
Why it's wrong here
Assigning the policy to each subscription individually would require many assignments and would not automatically apply to new subscriptions unless the team also updates the assignments. This is not the most efficient approach for a single, organization-wide policy.
- ✓
The root management group
Why this is correct
Assigning the policy at the root management group scope applies it to all child management groups and all subscriptions within them, including any new subscriptions created in the future. This is the correct approach for a single assignment that covers the entire organization.

Why it's wrong here
Assigning the policy at a resource group scope only affects resources within that specific resource group, not the subscriptions or management groups. This would not meet the requirement to restrict deployments across the entire organization.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may think assigning at the child management group level is sufficient, but they overlook that the root management group provides a single assignment point that automatically covers all current and future subscriptions across the entire organization with minimal overhead.
Detailed technical explanation
How to think about this question
Azure Policy inheritance follows the management group hierarchy: policies assigned at the root management group are inherited by all child management groups and subscriptions, and this inheritance is enforced even for subscriptions created after the policy assignment. The root management group is the top-level container in the Azure hierarchy, and any policy assigned there applies to the entire tenant, including all subscriptions under any management group. This design allows centralized governance without needing to update assignments when new subscriptions or management groups are added.
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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.

Variation 1. A company has 10 Azure subscriptions organized under two management groups: Production and Non-Production. The governance team needs to enforce a policy that all Azure resources must be deployed only in the East US or West US Azure regions. The policy must apply to every subscription under both management groups, including any new subscriptions added in the future, without requiring separate assignments per subscription. Which Azure feature should the team use to achieve this with the least administrative effort?
medium- A.Assign the 'Allowed Locations' Azure Policy definition to each individual subscription.
- ✓ B.Assign the 'Allowed Locations' Azure Policy definition to the root management group.
- C.Create a custom Azure RBAC role that restricts the region property and assign it to all users.
- D.Apply an Azure Resource Manager read-only lock to each subscription.
Why B: Assigning the 'Allowed Locations' Azure Policy definition to the root management group ensures the policy is inherited by all child management groups (Production and Non-Production) and all subscriptions under them, including any new subscriptions added in the future. This approach requires only a single assignment and minimizes administrative effort compared to per-subscription assignments.
