Quick Answer
The answer is the Anti-malware policy. This policy is the correct choice because it is specifically designed to detect and handle malware in email messages, including malicious attachments, and can be configured to automatically redirect those messages to a quarantine folder for admin review rather than delivering them to the user. On the Microsoft 365 Administrator MS-102 exam, this question tests your understanding of the distinct roles of protection policies in Defender for Office 365, where the Anti-malware policy handles malware quarantine, while Anti-spam policies manage junk and phishing, and Safe Attachments policies focus on detonation and analysis. A common trap is confusing Safe Attachments with the Anti-malware policy, but remember that Safe Attachments uses a virtual environment to check attachments before delivery, whereas the Anti-malware policy quarantines known malicious files after detection. Memory tip: think "Malware = Quarantine" for the direct redirect action.
This MS-102 practice question tests your understanding of deploy and manage a microsoft 365 tenant. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
Your organization uses Microsoft Defender for Office 365. You need to configure a policy that automatically redirects emails containing malicious attachments to a quarantine folder for admin review. What type of policy should you create?
Safe Attachments policy.
Why wrong: Safe Attachments uses detonation, but quarantine is set in anti-malware policies.
Anti-malware policy.
Anti-malware policies can quarantine messages with malware.
Anti-spam policy.
Why wrong: Anti-spam policies filter junk mail, not malware.
Safe Links policy.
Why wrong: Safe Links protects against malicious URLs, not attachments.

Correct answer & explanation
Anti-malware policy.
B is correct because the Anti-malware policy in Microsoft Defender for Office 365 is specifically designed to handle malware detected in email messages, including attachments. When configured, it can automatically redirect messages containing malicious attachments to a quarantine folder for admin review, providing a controlled remediation workflow.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Microsoft often tests the distinction between Anti-malware (for attachment malware) and Safe Attachments (for advanced sandbox analysis), leading candidates to mistakenly choose Safe Attachments when the core requirement is simply redirecting known malicious attachments to quarantine.
Detailed technical explanation
Under the hood, the Anti-malware policy uses the Microsoft Malware Protection Engine to scan email attachments against known malware signatures and heuristics. When a match is found, the policy can apply actions such as 'Redirect email messages to a specific email address' or 'Quarantine message', with the quarantine option storing the message in the admin-only quarantine for review. A subtle behavior is that the Anti-malware policy also supports zero-hour auto purge (ZAP) for malware already delivered, which retroactively moves messages to quarantine if a malware signature is updated after delivery.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
