The answer is Administrative Units, because they provide the precise delegation scope needed to restrict the help desk’s password reset permissions to only the Finance department in Microsoft Entra ID. Administrative Units allow you to define a subset of users, groups, or devices—mirroring your on-premises Organizational Units—and then assign an administrative role, like Helpdesk Administrator, scoped exclusively to that unit. On the SC-900 exam, this concept tests your understanding of granular role-based access control versus broad tenant-wide assignments; a common trap is confusing Administrative Units with Azure management groups or simple role assignments that lack a scope boundary. Remember the memory tip: “AU = Admin Unit = a container for delegated control,” and think of it as the cloud equivalent of an on-premises OU for permissions.
SC-900 Practice Question: Describe the concepts of security, compliance, and identity
This SC-900 practice question tests your understanding of describe the concepts of security, compliance, and identity. 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 uses Microsoft Entra ID and has multiple departments with separate organizational units (OUs) in its on-premises Active Directory. The help desk team needs to be able to reset passwords for users only in the Finance department. What feature should be used to delegate this administrative scope?
Why wrong: Dynamic groups automatically add or remove members based on rules but do not delegate administrative scopes to specific users.
B
Administrative Units
Administrative Units enable scoped administration by defining a subset of users or devices, allowing delegated access to resources within that scope only.
C
Conditional Access policies
Why wrong: Conditional Access policies enforce access controls during sign-in but do not delegate administrative permissions to manage users.
D
Privileged Identity Management (PIM)
Why wrong: PIM provides time-based and approval-based role activation but does not restrict the management scope to a specific department.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Administrative Units
Administrative Units (AUs) in Microsoft Entra ID allow you to delegate administrative permissions over a subset of users, groups, or devices without granting broader tenant-wide access. By creating an AU for the Finance department and assigning the Helpdesk Administrator role scoped to that AU, the help desk team can reset passwords only for Finance users, matching the on-premises OU structure.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is confusing delegation of administrative scope (Administrative Units) with membership automation (Dynamic groups) or access control (Conditional Access), leading candidates to pick a feature that manages users rather than one that limits administrative permissions.
Detailed technical explanation
How to think about this question
Administrative Units map to on-premises OUs conceptually but are implemented as containers in Entra ID. When you assign a role (e.g., Helpdesk Administrator) scoped to an AU, the role member can only manage objects within that AU, even if they hold the same role tenant-wide. This scoping is enforced via the RBAC authorization engine, which checks the user's scope membership before allowing operations like password reset (using the Graph API's `passwordProfile` property).

Key takeaway

Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
