SC-200 Mitigate threats using Microsoft Defender XDR Practice Question
This SC-200 practice question tests your understanding of mitigate threats using microsoft defender xdr. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 analyst is investigating a user who may have been compromised. The analyst sees a sign-in from an unusual location and then a series of suspicious actions performed by that user, including deleting files and sending emails. The analyst wants to find all emails sent by the user after the anomalous sign-in. Which advanced hunting tables should be used?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
EmailEvents and IdentityLogonEvents
Option A is correct because the investigation requires correlating a specific sign-in event (from IdentityLogonEvents) with subsequent email activity (from EmailEvents). IdentityLogonEvents captures authentication details including location, while EmailEvents records email send/receive metadata. Joining these tables on the user principal name (UPN) and timestamp allows the analyst to filter all emails sent after the anomalous sign-in.
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.
✓
EmailEvents and IdentityLogonEvents
Why this is correct
EmailEvents provides the email data, and IdentityLogonEvents provides sign-in times to correlate and find emails sent after the suspicious sign-in.

✗
EmailEvents and DeviceFileEvents
Why it's wrong here
DeviceFileEvents are for file operations on devices, not directly related to email sending.
✗
IdentityLogonEvents and DeviceEvents
Why it's wrong here
Missing the email table; DeviceEvents may not include email activity (depends on data source).
✗
EmailAttachmentInfo and EmailUrlInfo alone
Why it's wrong here
These lack the sender and full email metadata needed to identify emails sent by the user.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse DeviceFileEvents or DeviceEvents with email-related tables, forgetting that email actions are logged in EmailEvents, not in endpoint-level event tables.
Detailed technical explanation
How to think about this question
Under the hood, IdentityLogonEvents in Microsoft Defender XDR uses the AADSignInEventsBeta schema, which includes fields like LogonType, IPAddress, and Country. EmailEvents uses the EmailEvents schema with fields such as DeliveryAction, SenderFromAddress, and Timestamp. A real-world scenario might involve an attacker using a stolen token to sign in from a foreign IP, then sending phishing emails internally; joining these tables on AccountUpn and Timestamp with a > operator isolates the malicious email burst.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
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 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.
