The answer is a Microsoft Purview Data Loss Prevention policy for SharePoint and OneDrive. This is correct because a DLP policy can automatically detect files containing sensitive content like 'Project X' and block external sharing in both Teams and SharePoint Online, enforcing protection without manual user intervention. On the SC-900 exam, this question tests your understanding of how DLP policies differ from other security controls—a common trap is confusing DLP with sensitivity labels, which only classify content but do not automatically block sharing. Remember that DLP is the only native Microsoft 365 tool that can both identify and prevent the sharing of intellectual property with external users in real time. For a quick memory tip: think "DLP = Detect, Lock, Prevent" for external sharing of sensitive data.

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.
