Quick Answer
The answer is Microsoft Purview Information Protection. This feature is correct because it enables document owners to revoke access to confidential documents shared externally, even after the file has been downloaded, by applying persistent protection through Azure Rights Management. When a document is protected with usage rights, revocation strips the decryption key from all copies, rendering them unreadable regardless of where they are stored. On the SC-900 exam, this scenario tests your understanding of how Information Protection differs from Data Loss Prevention (DLP), which can only block future sharing, not undo past access. A common trap is confusing revocation with DLP policies or audit logs, but remember: only Information Protection can claw back already-downloaded files. For the exam, think of it as “protect first, revoke later”—if the document wasn’t protected before sharing, revocation is impossible. Memory tip: “Protection is the only one that can take it back.”
This SC-900 practice question tests your understanding of describe the capabilities of microsoft compliance solutions. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 user accidentally shared a confidential document with an external vendor. You need to revoke access immediately for all copies, even if the file has been downloaded. Which Microsoft Purview feature should you use?

Why it matters: Time or reboot constraint — the correct answer must take effect right away without requiring a reboot or reload.
Microsoft Purview Information Protection
Information Protection enables revocation of access to protected documents.
Retention policy
Why wrong: Retention policies manage deletion, not access revocation.
Data loss prevention (DLP) policy
Why wrong: DLP blocks sharing but cannot revoke already shared files.
Audit log search
Why wrong: Audit logs record events, don't enforce actions.

Correct answer & explanation
Microsoft Purview Information Protection
Option D is correct because Microsoft Purview Information Protection allows the owner to revoke access to protected documents, including downloaded copies. Option A is wrong because DLP policies detect and block sharing but cannot revoke already shared files. Option B is wrong because retention policies manage lifecycle, not revocation. Option C is wrong because audit logs record events but do not enforce revocation.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
