The answer is to ensure the user’s email address is configured in the MDI alert settings. Microsoft Defender for Identity relies on the email field within the user’s Active Directory or Azure AD object to route alerts for suspicious network connections; if this field is blank or incorrect, the alert engine cannot deliver notifications for that specific account, even when anomalous behavior is detected. On the MS-102 exam, this question tests your understanding that MDI alert delivery is user-specific, not sensor-wide, and the common trap is to immediately suspect sensor health or licensing when the issue is isolated to one account. A strong memory tip is “One user, one email field—no email, no alert,” reminding you that the first troubleshooting step for a single missing alert is always to verify the user’s mail attribute in the directory.
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 company is using Microsoft Defender for Identity (MDI) and wants to receive alerts when a user account is involved in a suspicious network connection. The security team has enabled MDI alerts but is not receiving any alerts for a specific account that is showing anomalous behavior. What should the team check first?

Clue: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Ensure the user's email address is configured in the MDI alert settings.
Option C is correct because MDI needs to be configured with the user's email address for alerts to be sent. If the email is missing or incorrect, alerts will not be delivered. Option A is wrong because the sensor status would affect all accounts, not just one. Option B is wrong because licensing is per user. Option D is wrong because directory data is not required for alerts.
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.

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.
