AZ-900 Describe Azure management and governance Practice Question
A company has a root management group that contains all Azure subscriptions. A centralized governance team needs to create and assign Azure Policy definitions and set initiatives that apply to all subscriptions. Which built-in role should be assigned to the governance team at the root management group scope to grant the minimum required permissions?
⚠ Common exam trap
A common mix-up: candidates confuse the Contributor role (which can manage resources but not policies) with the Policy Contributor role, or assume that Owner is required because policy assignments affect all resources, but Azure provides a dedicated built-in role specifically for policy management to enforce least privilege.
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
✓
Policy Contributor
The Policy Contributor built-in role grants the minimum required permissions to create and assign Azure Policy definitions and initiatives, including the ability to read policy assignments and manage policy resources, without granting full write access to all resources. Assigning this role at the root management group scope ensures the governance team can apply policies across all subscriptions while adhering to the principle of least privilege.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Owner
Why it's wrong here
Owner grants full access to manage all resources, including the ability to delegate access to others. This is excessive for a team that only needs to manage policies and does not meet the 'minimum required permissions' requirement.
When this WOULD be correct
This role would be correct if the question asked for a role that allows full management of all resources, including policy assignments and role assignments, at the root management group scope, such as for a super administrator.
- ✗
Contributor
Why it's wrong here
Contributor is a built-in RBAC role that grants full management rights over all resources and resource groups, including the ability to create, update, and delete them, but it cannot delegate access or manage role assignments. For a team whose sole responsibility is creating and editing Azure Policy definitions, initiatives, and assignments, Contributor is over-permissive because it allows actions such as modifying virtual machines, storage accounts, or network configurations—operations completely unrelated to policy governance. This violates the principle of least privilege, which demands granting only the specific permissions necessary to perform required tasks, and could lead to unintended configuration changes or data exposure if a policy administrator makes a mistake.
When this WOULD be correct
If the question asked for a role to deploy and manage all resources (e.g., virtual machines, storage) within a subscription or management group, but not manage access or policies, Contributor would be the correct answer.
- ✓
Policy Contributor
Why this is correct
Policy Contributor is designed specifically for managing Azure Policy resources. It allows creating, updating, and deleting policy definitions, initiatives, and assignments. At the root management group scope, this role enables policy governance across all subscriptions without granting broader management capabilities.
- ✗
Security Admin
Why it's wrong here
Security Admin provides permissions to manage security policies in Microsoft Defender for Cloud and other security features, but it does not grant the ability to create or manage Azure Policy definitions and assignments directly. It is not the correct role for this governance task.
When this WOULD be correct
A question asks: 'Which built-in role should be assigned to a security team to manage security policies and monitor security alerts across all subscriptions?' In that scenario, Security Admin would be correct because it is designed for security policy management and monitoring.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The AZ-900 exam frequently reuses these exact scenarios with slightly different constraints.
✓Policy ContributorCorrect answer▾
Why this is correct
Policy Contributor is designed specifically for managing Azure Policy resources. It allows creating, updating, and deleting policy definitions, initiatives, and assignments. At the root management group scope, this role enables policy governance across all subscriptions without granting broader management capabilities.
✗OwnerWrong answer — click to see why▾
Why this is wrong here
The Owner role grants full access to all resources, including the ability to assign roles and manage policies, which exceeds the minimum required permissions for creating and assigning Azure Policy definitions and initiatives.
★ When this WOULD be the correct answer
This role would be correct if the question asked for a role that allows full management of all resources, including policy assignments and role assignments, at the root management group scope, such as for a super administrator.
Why candidates choose this
Candidates may think that creating and assigning policies requires the highest level of permissions, similar to full administrative control, leading them to choose Owner instead of the more specific Policy Contributor role.
✗ContributorWrong answer — click to see why▾
Why this is wrong here
The Contributor role can create and manage resources but cannot assign policies or manage access. The question requires assigning Azure Policy definitions and initiatives, which is beyond Contributor's permissions.
★ When this WOULD be the correct answer
If the question asked for a role to deploy and manage all resources (e.g., virtual machines, storage) within a subscription or management group, but not manage access or policies, Contributor would be the correct answer.
Why candidates choose this
Candidates may assume Contributor is sufficient because it allows creating and managing most Azure resources, not realizing that policy management requires a specific role like Policy Contributor.
✗Security AdminWrong answer — click to see why▾
Why this is wrong here
The Security Admin role grants permissions to manage security policies and view security alerts, but it does not include the ability to create and assign Azure Policy definitions and initiatives. The question requires a role that specifically allows policy management across all subscriptions, which is provided by Policy Contributor.
★ When this WOULD be the correct answer
A question asks: 'Which built-in role should be assigned to a security team to manage security policies and monitor security alerts across all subscriptions?' In that scenario, Security Admin would be correct because it is designed for security policy management and monitoring.
Why candidates choose this
Candidates may confuse security policies with Azure Policy, assuming that a role with 'Security' in its name can manage all types of policies, including Azure Policy definitions and initiatives.
