Quick Answer
The answer is Azure Policy with allowed locations. This service enforces region restrictions by using a built-in policy definition that denies any resource creation outside the specified regions, such as Europe West, directly meeting data sovereignty requirements. When assigned to a subscription or resource group scope, Azure Policy evaluates every deployment request and blocks those that violate the allowed locations rule, ensuring compliance without manual oversight. On the AZ-900 exam, this scenario tests your understanding of Azure Policy’s role in governance and compliance, often contrasting it with Azure Blueprints or RBAC—a common trap is confusing policy enforcement with access control. Remember the mnemonic: “Policy Polices, RBAC Permits”—Azure Policy dictates what can be deployed and where, while RBAC controls who can deploy it.
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 wants to ensure that all Azure resources they deploy are created in the Europe West region to comply with data sovereignty requirements. They want to block creation of resources in any other region. Which Azure service should they use?
Resource groups
Why wrong: Resource groups do not have region restriction capabilities.
Management groups
Why wrong: Management groups organize subscriptions but do not enforce region restrictions.
Azure Policy with allowed locations
Azure Policy can deny creation of resources outside allowed regions.
Azure Blueprints
Why wrong: Blueprints can include policies, but the policy itself is what enforces the restriction.

Correct answer & explanation
Azure Policy with allowed locations
Azure Policy with the 'allowed locations' built-in policy definition can enforce that all resources are deployed only in the Europe West region. When assigned to a subscription or resource group scope, this policy denies any resource creation outside the specified regions, directly meeting the data sovereignty requirement.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Resource groups
Why it's wrong here
Resource groups do not have region restriction capabilities.
Management groups
Why it's wrong here
Management groups organize subscriptions but do not enforce region restrictions.
Azure Policy with allowed locations
Why this is correct
Azure Policy can deny creation of resources outside allowed regions.

Azure Blueprints
Why it's wrong here
Blueprints can include policies, but the policy itself is what enforces the restriction.
Common exam traps
The trap here is that candidates often confuse Azure Policy with Azure Blueprints, thinking Blueprints directly enforce restrictions, when in fact Blueprints package policies but the enforcement itself comes from Azure Policy.
Detailed technical explanation
Azure Policy uses a deny effect that is evaluated at resource creation time by the Azure Resource Manager (ARM). The 'allowed locations' policy leverages the 'Microsoft.Authorization/policyDefinitions' resource type and can be scoped to management groups, subscriptions, or resource groups. A subtle behavior is that this policy does not block moving existing resources into a non-allowed region, only creation or deployment; for full compliance, a separate 'deny location change' policy may be needed.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
