Question 1mediummultiple choice
Full question →mediummultiple choiceObjective-mapped
A company has multiple Azure subscriptions used by different departments. The security team wants to enforce a requirement that all Azure Storage accounts in every subscription must be encrypted at rest using customer-managed keys (CMK). The solution must automatically evaluate existing and new storage accounts for compliance, and it must be able to automatically remediate non-compliant resources by enabling CMK encryption. The team wants to use a single, centralized Azure feature that can be assigned once and apply to all subscriptions. Which Azure feature should they use?
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
Best answer
Azure Policy
Azure Policy can be assigned at a management group or subscription level to audit and automatically enforce compliance rules. It includes built-in policies for storage encryption with customer-managed keys and can perform automatic remediation. This is the correct choice because it allows centralized governance across multiple subscriptions.
B
Distractor review
Azure Blueprints
Azure Blueprints are used to define a repeatable set of Azure resources and policies that adhere to organizational standards. However, they are primarily used for deploying new environments, not for continuously evaluating or enforcing compliance on existing resources. They are not the best fit for ongoing compliance monitoring and automatic remediation.
C
Distractor review
Azure Role-Based Access Control (RBAC)
Azure RBAC manages who can perform actions on Azure resources. It controls permissions but does not enforce resource configuration such as encryption settings. RBAC cannot automatically remediate non-compliant storage accounts or audit encryption status.
D
Distractor review
Azure Security Center (Microsoft Defender for Cloud)
Azure Security Center provides security recommendations and threat detection, including identifying storage accounts without encryption. However, it does not automatically enforce or remediate configurations. To enable automatic enforcement and remediation, you would need to integrate with Azure Policy, making Azure Policy the primary service for this requirement.
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: Azure Policy — Azure Policy is the correct service for enforcing governance rules across Azure resources. It can audit compliance and automatically remediate non-compliant resources using built-in policies or custom policies. In this scenario, a built-in policy like 'Storage accounts should use customer-managed key for encryption' can be assigned at a management group level to cover all subscriptions. Azure Blueprints are used to package and deploy consistent environments, not to enforce rules on existing resources. Azure RBAC controls access permissions, not resource configuration. Azure Security Center (now Microsoft Defender for Cloud) provides security recommendations but does not automatically enforce resource configurations like encryption without additional Azure Policy integration.
