The correct answer is to assign the Helpdesk Administrator role to the group and create an administrative unit scoped to the Users OU. This works because the Helpdesk Administrator role grants the least-privilege permissions needed for password resets, while an administrative unit (AU) allows you to limit that role’s scope to only the users synced from a specific on-premises OU, such as the Users OU. On the MS-102 exam, this scenario tests your understanding of combining Azure AD roles with administrative units to enforce granular delegation, a common requirement when using Azure AD Connect with password hash sync. A frequent trap is assigning a broader role like User Administrator or forgetting to scope the AU, which would give the help desk access to all users. Remember the pairing: role for permission, AU for scope—think “role and scope, like a telescope.”
MS-102 Manage users, groups, licensing, and support Practice Question
This MS-102 practice question tests your understanding of manage users, groups, licensing, and support. 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.
You are the Microsoft 365 administrator for Fabrikam Inc., a company with 1,000 users. You have been asked to delegate the ability to reset passwords for all users to the help desk team. The help desk team consists of five users. You want to grant them the minimum necessary permissions. Additionally, you need to ensure that the help desk team can only reset passwords for users in the 'Users' organizational unit (OU) in on-premises Active Directory. The company uses Azure AD Connect with password hash sync. You create a security group named 'HelpDeskGroup' and add the help desk users to it. What should you do next?

Correct answer & explanation
✓
Assign the Helpdesk Administrator role to the group and create an administrative unit scoped to the Users OU
Option C is correct because the Helpdesk Administrator role provides the least-privilege permissions for password resets, and creating an administrative unit (AU) scoped to the 'Users' OU allows you to restrict the role's management scope to only those users synced from that specific on-premises OU. This combination meets the requirement to delegate password reset with minimal permissions and scope limitation.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Assign the Global Administrator role to the group
Why it's wrong here
Excessive permissions.
✗
Assign the User Administrator role to the group
Why it's wrong here
Allows creating users, not just password reset.
✓
Assign the Helpdesk Administrator role to the group and create an administrative unit scoped to the Users OU
Why this is correct
Scoped role assignment via administrative unit.

✗
Assign the Password Administrator role to the group and configure Azure AD Connect to restrict OU
Why it's wrong here
Password Administrator cannot reset passwords for non-admin users effectively; OU restriction not through AAD Connect.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse the Password Administrator role (which can reset passwords but cannot be scoped) with the Helpdesk Administrator role (which can be scoped via administrative units), or incorrectly believe that Azure AD Connect can restrict administrative permissions based on on-premises OUs.
Detailed technical explanation
How to think about this question
Administrative units in Azure AD allow you to delegate administrative roles to a subset of users, groups, or devices, effectively creating a management boundary. When using Azure AD Connect with password hash sync, the on-premises OU structure is reflected in Azure AD via the `distinguishedName` attribute, but role scoping must be done through administrative units, not by configuring Azure AD Connect to restrict OU. This ensures that the Helpdesk Administrator role can only reset passwords for users whose objects reside in the designated AU, which you create to mirror the on-premises 'Users' OU.

→Watch for words such as best, first, most likely and least administrative effort.

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.
