A key principle to apply: least privilege minimizes the potential impact of a security breach.. 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 business stakeholder asks how Microsoft 365 can help them guide assignment of Microsoft 365 admin roles. Microsoft 365 licensing, admin, or support concept is most relevant?
Microsoft Whiteboard
Why wrong: Whiteboard is for visual collaboration, not this licensing or admin requirement.
Microsoft Stream
Why wrong: Stream hosts video content and does not address this licensing or support need.
Least privilege

Microsoft Forms
Why wrong: Forms collects survey responses and does not meet this requirement.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Least privilege
The principle of least privilege is the most relevant concept for guiding assignment of Microsoft 365 admin roles. It dictates that users should be granted only the minimum permissions necessary to perform their job functions, which directly applies to assigning admin roles to reduce security risks. This is a core security and identity concept within Microsoft 365, not a specific application or service.
Key principle: Least privilege minimizes the potential impact of a security breach.

Common exam traps
The trap here is that candidates may confuse productivity tools (Whiteboard, Stream, Forms) with security or administrative concepts, failing to recognize that 'least privilege' is a fundamental security principle directly tied to role assignment in Microsoft 365.
Detailed technical explanation
The least privilege principle is implemented in Microsoft 365 through Role-Based Access Control (RBAC), where each admin role (e.g., Global Admin, Exchange Admin) has a predefined set of permissions. Microsoft recommends using Azure AD Privileged Identity Management (PIM) to enforce just-in-time access, further reducing standing privileges. A real-world scenario is assigning a 'User Admin' role instead of 'Global Admin' to manage user accounts, limiting exposure if the account is compromised.
Key takeaway
Least privilege minimizes the potential impact of a security breach.
Real-world example
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.
