The correct feature to configure is the User reported settings in the Microsoft 365 Defender portal. This is because these settings allow administrators to define exactly what happens when a user reports a phishing email from Outlook—specifically, they can route the report to trigger an automated investigation and response (AIR) policy, which can automatically block the sender and remediate the threat. On the MS-102 exam, this scenario tests your understanding of how user-reported phishing settings bridge the gap between end-user reporting and automated security actions, often appearing as a distractor against simply enabling the built-in anti-spam policies or third-party reporting add-ins. A common trap is assuming that enabling the Report Message add-in alone is sufficient; however, without configuring the user reported settings in the Defender portal to link to an AIR policy, no automatic blocking or investigation occurs. Memory tip: think of it as the “trigger” that turns a user’s click into an automated security response.
MS-102 Practice Question: Manage security and threats by using Microsoft Defender XDR
This MS-102 practice question tests your understanding of manage security and threats by using microsoft defender xdr. 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.
A security administrator notices that users are receiving phishing emails that evade built-in anti-spam filters. The administrator wants to enable users to report these suspicious emails from Outlook and have them automatically trigger an investigation and block the sender. Which feature should be configured in Microsoft Defender for Office 365?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
User reported settings in the Microsoft 365 Defender portal
User reported settings in the Microsoft 365 Defender portal allow administrators to configure how user-reported messages are handled. When enabled, users can report suspicious emails directly from Outlook, and these reports can automatically trigger an investigation and block the sender via automated investigation and response (AIR) policies. This directly addresses the requirement to have user-reported emails initiate security actions.
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.
✗
Attack simulation training
Why it's wrong here
Attack simulation training creates simulated phishing campaigns to train users; it does not automatically block senders based on reports.
✗
Threat Explorer
Why it's wrong here
Threat Explorer is for manual investigation of threats, not automated response to user reports.
✓
User reported settings in the Microsoft 365 Defender portal
Why this is correct
These settings can be configured to route reported messages for automated investigation and automatically block senders detected as malicious.

✗
Safe Links
Why it's wrong here
Safe Links scans and protects against malicious links in email but does not handle user reporting or automatic blocking.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse user reporting features with attack simulation training or threat hunting tools, not realizing that the specific setting to enable automated investigation and blocking from user reports is found in the User reported settings within the Microsoft 365 Defender portal.
Detailed technical explanation
How to think about this question
User reported settings integrate with the Microsoft 365 Defender portal's automated investigation and response (AIR) capabilities. When a user reports a message via the built-in Outlook Report Message add-in, the message is submitted to Microsoft for analysis, and if configured, can trigger an automated investigation that may result in the sender being blocked at the transport layer via tenant allow/block lists. This feature relies on the Exchange Online Protection (EOP) pipeline and the unified audit log to correlate user reports with threat intelligence.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
