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?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
Assign the 'Allowed Locations' Azure Policy definition to each individual subscription.
Assigning the policy to each subscription individually is possible but requires 10 separate assignments (and more if new subscriptions are added). This increases administrative overhead and does not automatically cover new subscriptions. Azure Policy supports assignment at management group scope to simplify inheritance.
B
Best answer
Assign the 'Allowed Locations' Azure Policy definition to the root management group.
Assigning the policy to the root management group applies the policy to all subscriptions under that group (including both Production and Non-Production). Any new subscriptions added to the hierarchy automatically inherit the policy. This is the most efficient method.
C
Distractor review
Create a custom Azure RBAC role that restricts the region property and assign it to all users.
Azure RBAC roles control permissions to perform actions, but they cannot restrict the allowed locations for resource deployment. Location restrictions are enforced through Azure Policy, not through role-based access control.
D
Distractor review
Apply an Azure Resource Manager read-only lock to each subscription.
Azure Resource Manager locks (ReadOnly or CanNotDelete) prevent deletion or modification of resources but do not restrict the regions where resources can be created. Locks are used for protecting resources, not for enforcing compliance rules like allowed locations.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.

FAQ
Questions learners often ask
What does this AZ-900 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Assign the 'Allowed Locations' Azure Policy definition to the root management group. — Azure Policy can define allowed locations (e.g., 'East US' and 'West US') using the 'Allowed Locations' built-in policy definition. By assigning this policy to a management group scope (such as the root management group), the policy automatically applies to all subscriptions within that management group's hierarchy, including future subscriptions. This approach requires a single assignment and ensures consistent enforcement across the entire organization. Other options are not suitable: assigning to each individual subscription (A) is manual and does not scale; custom RBAC roles (C) cannot restrict resource locations; Resource Manager locks (D) only prevent accidental deletion or modification but do not control deployment regions.
