Microsoft SC-300 - Microsoft Identity and Access Administrator

HR is a member of AU1: No

User1 is a member of AU1: Yes

User2 is a member of AU1: No

Let’s break this down step by step based on Microsoft Entra ID dynamic membership rules, administrative units, and group membership, as outlined in Microsoft Identity and Access Administrator documentation.

Understanding Administrative Units and Dynamic Membership in Microsoft Entra ID:

Administrative Units (AUs):Administrative Units in Microsoft Entra ID are used to delegate administrative tasks to a subset of users, groups, or devices. They allow you to scope administrative roles (e.g., User Administrator) to specific users or groups within the AU.

Membership Types for AUs:

Assigned Membership:Members (users, groups, or devices) are manually added to the AU by an administrator.

Dynamic Membership:Members are automatically added or removed based on a dynamic membership rule, similar to dynamic groups. Dynamic membership for AUs can be applied to users or devices (but not groups directly).

The question states that AU1 is initially configured for assigned membership but is then updated to useDynamic Usermembership with the rule (user.department -eq "HR").

Dynamic Membership Rule:The rule (user.department -eq "HR") means that AU1 will automatically include all users whose department attribute in Microsoft Entra ID is set to "HR". This rule applies to users, not groups or devices, because the membership type is "Dynamic User."

Impact of Changing AU1 to Dynamic Membership:

When AU1’s membership type is changed from assigned to dynamic, the existing assigned memberships (e.g., User2, HR group, IT group) are no longer relevant. Thedynamic rule takes over, and AU1’s membership is determined solely by the rule (user.department -eq "HR").

Dynamic User Membership:Only users whose attributes match the rule will be members of AU1. Groups (like HR and IT) are not evaluated by this rule because the membership type is "Dynamic User," not "Dynamic Group."

Let’s evaluate the users based on the rule:

User1:Department = "HR". The rule (user.department -eq "HR") matches, so User1 will be dynamically added to AU1.

User2:Department = "IT". The rule does not match, so User2 will not be a member of AU1, even though they were previously assigned to AU1 and are a member of the IT group.

Groups (HR and IT):The dynamic membership rule for AU1 applies to users, not groups. Therefore, groups like HR and IT are not directly evaluated by the rule. However, we need toconsider whether group membership in AU1 affects the statements.

Statement 1: HR is a member of AU1:

Analysis:

The HR group is listed in the second table with AU1 as its administrative unit, indicating that it was initially assigned to AU1 when AU1 used assigned membership.

However, AU1’s membership type has been updated to "Dynamic User" with the rule (user.department -eq "HR"). Dynamic User membership applies to users, not groups.

In Microsoft Entra ID, administrative units with dynamic user membership do not include groups as members unless the AU’s membership type is explicitly set to "Dynamic Group" (which is not the case here).

When AU1 was changed to dynamic membership, the HR group would no longer be considered a member of AU1 because the dynamic rule only evaluates users. Groups are not dynamically added to AUs based on user attributes.

Conclusion:The HR group is not a member of AU1 after the change to dynamic membership. Therefore, this statement isNo.

Statement 2: User1 is a member of AU1:

Analysis:

User1 has the department attribute set to "HR" (from the first table).

The dynamic membership rule for AU1 is (user.department -eq "HR"), which matches User1’s department.

Therefore, User1 will be automatically added to AU1 as a member based on the dynamic rule.

Additionally, User1 is a member of the HR group, which was initially assigned to AU1. However, since AU1 now uses dynamic membership, the HR group’s assignment to AU1 is irrelevant. User1’s membership in AU1 is determined solely by the dynamic rule, not their group membership.

Conclusion:User1 is a member of AU1 because their department matches the dynamic rule. Therefore, this statement isYes.

Statement 3: User2 is a member of AU1:

Analysis:

User2 has the department attribute set to "IT" (from the first table).

The dynamic membership rule for AU1 is (user.department -eq "HR"), which does not match User2’s department.

User2 was initially assigned to AU1 (as shown in the first table) and is a member of the IT group, which was also assigned to AU1. However, when AU1’s membership type was changed to "Dynamic User," the assigned memberships (including User2 and the IT group) are no longer relevant.

The dynamic rule only includes users with the department "HR," so User2 is not added to AU1.

Conclusion:User2 is not a member of AU1 because their department does not match the dynamic rule. Therefore, this statement isNo.

Additional Considerations:

If AU1’s membership type were "Dynamic Group" instead of "Dynamic User," we would evaluate whether the HR and IT groups match a group-based rule. However, the question specifies "Dynamic User," so the rule applies to user attributes only.

The initial assigned memberships (e.g., User2, HR group, IT group) are overridden by the dynamic membership rule. Microsoft Entra ID does not retain assigned memberships when an AU or group is converted to dynamic membership.

The HR and IT groups being assigned to AU1 initially does not affect the dynamic membership of users, but it might be relevant for administrative scoping (e.g., if an admin role is scoped to AU1). However, the statements are about membership, not administrative roles.

Conclusion:Based on the dynamic membership rule (user.department -eq "HR") for AU1:

HR group:Not a member of AU1 because dynamic user membership does not apply to groups.

User1:A member of AU1 because their department is "HR," matching the rule.

User2:Not a member of AU1 because their department is "IT," which does not match the rule.Therefore, the answers are:

HR is a member of AU1:No

User1 is a member of AU1:Yes

User2 is a member of AU1:No

Yes, No, Yes

No

No

Yes

a) When you assign a group to an application, only users in the group will have access. The assignment does not cascade to nested groups.

b) Tested in lab, existing owners will be replaced. Also direct assignment (resource owner) is path of least privilege. (replicated in test)

c) Application setting 'visible to users' is set to No, then no users see this application on their My Apps portal and O365 launcher.

User1 must request access to App1 before they can use the app: No

If User2 requests access to App1, they will be added to Group1 automatically: Yes

User2 can approve App1 requests by using the Microsoft Entra admin center: Yes

Let’s break this down step by step based on Microsoft Entra ID self-service application access and the configured settings, as outlined in Microsoft Identity and Access Administrator documentation.

Understanding Self-Service Application Access in Microsoft Entra ID:

Self-service application access in Microsoft Entra ID allows users to request access to applications without needing an administrator to manually assign them. This is configured on a per-application basis.

The settings for App1 are:

Allow users to request access to this application: Yes– Users can request access to App1.

To which group should assigned users be added: Group1– Users who are granted access will be added to Group1, which provides the necessary permissions to use App1.

Require approval before granting access to this application: Yes– Access requests must be approved before the user is added to Group1.

Who is allowed to approve access to this application: User2– User2 is the designated approver for access requests to App1.

Statement 1: User1 must request access to App1 before they can use the app.

Analysis:

User1 is already a member of Group1, as stated in the question.

The self-service settings specify that users who are granted access to App1 will be added to Group1. This implies that membership in Group1 is what grants access to App1.

Since User1 is already a member of Group1, they already have access to App1. In Microsoft Entra ID, if a user is already assigned to an application (either directly or via group membership), they do not need to request access through the self-service process—they can simply use the app.

The self-service access request process is for users who are not yet assigned to the app (i.e., not in Group1). Since User1 is already in Group1, they do not need to request access.

Conclusion:This statement isNo. User1 does not need to request access because they are already a member of Group1 and can use App1 immediately.

Statement 2: If User2 requests access to App1, they will be added to Group1 automatically.

Analysis:

User2 is not a member of Group1 (the question does not state that User2 is in Group1).

The self-service settings allow users to request access to App1, and the setting "To which group should assigned users be added: Group1" means that users who are granted access will be added to Group1.

However, the setting "Require approval before granting access to this application: Yes" means that User2’s request must be approved before they are added to Group1. The approver for App1 requests is User2 themselves, which introduces a potential conflict.

In Microsoft Entra ID, if a user is both the requester and the approver, the system typicallyallows them to approve their own request (unless additional policies prevent this, which is not specified in the question). Therefore, User2 can request access and approve their own request.

Once the request is approved, User2 will be added to Group1 automatically as per the self-service settings. The term "automatically" in the statement refers to the process after approval—once approved, the addition to Group1 happens without further manual intervention.

Conclusion:This statement isYes. If User2 requests access to App1 and approves their own request, they will be added to Group1 automatically.

Statement 3: User2 can approve App1 requests by using the Microsoft Entra admin center.

Analysis:

The self-service settings specify that User2 is the designated approver for access requests to App1.

In Microsoft Entra ID, approvers can manage access requests through the Microsoft Entra admin center (via the "My Access" portal or the "Access Requests" section, depending on their role and permissions).

User2, as the designated approver, will receive a notification (via email or the My Access portal) when a request is made. They can then log into the Microsoft Entra admin center, navigate to the access requests section, and approve or deny the request.

Even though User2 is not explicitly an admin, the fact that they are designated as the approver for App1 requests grants them the ability to approve requests through the Microsoft Entra admin center.

Conclusion:This statement isYes. User2 can approve App1 requests using the Microsoft Entra admin center.

Additional Considerations:

If User2 were not allowed to approve their own request (e.g., due to a separation of duties policy), Statement 2 might be affected. However, Microsoft Entra ID does not enforce such a restriction by default, and the question does not specify any additional policies.

The Microsoft Entra admin center is the primary interface for managing access requests, but users can also approve requests via email links or the My Access portal. The statement specifically mentions the admin center, which is a valid method.

Conclusion:

Statement 1:No– User1 does not need to request access since they are already in Group1.

Statement 2:Yes– User2 will be added to Group1 automatically after their request is approved (by themselves).

Statement 3:Yes– User2 can approve requests using the Microsoft Entra admin center.
