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. 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 wants to create a custom detection rule that triggers when a user receives a phishing email that bypassed Exchange Online Protection, and then clicks a link that leads to a known malicious domain. Which two advanced hunting tables should the analyst combine to detect this chain of events?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
EmailEvents and UrlClickEvents
Option B is correct because the detection requires correlating the email receipt (EmailEvents) with the user's click on a malicious link (UrlClickEvents). EmailEvents captures email delivery details, while UrlClickEvents records user clicks on URLs in email messages, including those that bypassed Exchange Online Protection. Combining these two tables allows the analyst to identify the specific chain: a user received a phishing email and then clicked a link to a known malicious domain.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
EmailEvents and DeviceNetworkEvents
Why it's wrong here
DeviceNetworkEvents shows network connections but not the email receipt or which URLs were clicked.
✓
EmailEvents and UrlClickEvents
Why this is correct
EmailEvents tracks email delivery and UrlClickEvents tracks when users click URLs in email. Combining them allows correlation.

✗
EmailEvents and IdentityLogonEvents
Why it's wrong here
IdentityLogonEvents tracks user sign-ins, not click events.
✓
UrlClickEvents and DeviceNetworkEvents
Why this is correct
While UrlClickEvents shows clicks, DeviceNetworkEvents shows subsequent network connections but does not include the email context.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse DeviceNetworkEvents with user click events, assuming network-level logs can replace UrlClickEvents, but DeviceNetworkEvents does not capture the user's click action on an email link or the email context (e.g., NetworkMessageId).

Command / output trap
DeviceNetworkEvents shows network connections but not the email receipt or which URLs were clicked.
Detailed technical explanation
How to think about this question
UrlClickEvents in Microsoft Defender for Office 365 (part of Microsoft 365 Defender) records each time a user clicks a URL in an email, including the verdict (allowed, blocked, etc.) and the URL itself. EmailEvents provides the email's unique identifier (NetworkMessageId), which can be joined with UrlClickEvents on the same identifier to link the email to the click. This correlation is essential for detecting time-of-click threats where the URL was initially safe but later weaponized, a common bypass technique for EOP.

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.
