The correct answer is to enable Zero-hour auto purge (ZAP) in the anti-malware policy. ZAP is the specific feature in Microsoft Defender for Office 365 that retroactively detects and removes malware from messages that have already been delivered to a user’s mailbox, moving them to quarantine or the Junk Email folder. This works because ZAP continuously monitors mailbox content against updated threat intelligence, allowing it to automatically remove malware after delivery without requiring user action. On the MS-102 exam, this question tests your understanding of post-delivery protection mechanisms versus pre-delivery filters like Safe Attachments or Safe Links; a common trap is confusing ZAP with manual remediation or retention policies. Remember the mnemonic “ZAP After Delivery” to recall that ZAP handles the post-delivery cleanup of malware, while other policies block threats before they reach the inbox.

Your company is deploying Microsoft Defender for Office 365. The security team wants to automatically remove messages identified as malware from all mailboxes after delivery. What should you configure?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable Zero-hour auto purge (ZAP) in the anti-malware policy.
Zero-hour auto purge (ZAP) is the correct feature because it automatically detects and removes messages that are identified as malware after they have already been delivered to a user's mailbox. By enabling ZAP in the anti-malware policy, the system retroactively moves malicious messages to the user's Junk Email folder or quarantines them, ensuring post-delivery protection without manual intervention.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Configure an anti-malware policy with a high-confidence verdict.
Why it's wrong here
Anti-malware policies do not automatically remove delivered messages.
✓
Enable Zero-hour auto purge (ZAP) in the anti-malware policy.
Why this is correct
ZAP automatically removes malware after delivery.

Read the scenario before looking for a memorised answer.
✗
Set up a mailbox intelligence policy.
Why it's wrong here
Mailbox intelligence is for user-reported messages.
✗
Create an anti-phishing policy to block spoofed senders.
Why it's wrong here
Anti-phishing policies do not handle malware removal.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse ZAP with initial filtering policies, assuming that configuring a high-confidence verdict in the anti-malware policy alone will handle post-delivery removal, when in fact ZAP must be explicitly enabled for that purpose.
Detailed technical explanation
How to think about this question
ZAP works by continuously scanning messages in Exchange Online mailboxes against updated threat intelligence, using the same detection engines as the initial transport scan. If a message is later determined to be malware, ZAP moves it to quarantine or the Junk Email folder, and the action is logged in the Threat Protection Status report. A real-world scenario where this matters is when a zero-day malware variant bypasses initial filters but is later identified via signature updates, allowing ZAP to clean mailboxes retroactively.

Real-world example
How this comes up in practice
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.
