The answer is EmailEvents and UrlClickEvents. This is correct because EmailEvents logs every email delivery event, including phishing messages that reach the inbox, while UrlClickEvents records each time a user clicks a link within an email, capturing the target domain. By joining these two tables on the network message ID, you can directly correlate the specific email delivery to the subsequent link click, enabling the email delivery to link click correlation that the custom detection rule requires. On the MS-102 exam, this tests your ability to build advanced hunting queries in Microsoft Defender XDR, a key skill for security analysts; a common trap is confusing UrlClickEvents with EmailUrlInfo, which only lists URLs in emails without recording actual clicks. Remember the mnemonic “Delivered then Clicked” — EmailEvents for the delivery, UrlClickEvents for the click — and you’ll always join the right pair.
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. A key principle to apply: emailEvents logs email delivery and processing details.. 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 in Microsoft Defender XDR that triggers when a user receives a phishing email (delivered to inbox) and later clicks a link from that email that leads to a known malicious domain. The rule will be based on an advanced hunting query. Which two tables should the analyst join in the query to capture both the email delivery event and the link click event? (Choose two.)
This table contains details of email delivery events, including whether the email was delivered to the inbox, and the unique NetworkMessageId that can link to click events.
B
UrlClickEvents
This table records user clicks on URLs within emails, including the target URL and the user who clicked. Joining with EmailEvents identifies which email led to the click.
C
DeviceEvents
Why wrong: DeviceEvents logs process and security events on endpoints, but does not directly capture email link clicks. It is not used in an email click detection scenario.
D
IdentityLogonEvents
Why wrong: This table tracks user authentication events and is not relevant to email events or link clicks.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
EmailEvents
EmailEvents contains records of email delivery events, including phishing emails that were delivered to the inbox. UrlClickEvents captures user clicks on URLs in emails, including the target domain. Joining these two tables on the email's network message ID allows the analyst to correlate the specific phishing email delivery with the subsequent link click to a known malicious domain, which is the exact scenario described.
Key principle: EmailEvents logs email delivery and processing details.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse UrlClickEvents with DeviceEvents, thinking that a link click is a device-level action, but in Microsoft Defender XDR, URL clicks from emails are specifically tracked in the UrlClickEvents table, not in endpoint event tables.
Trap categories for this question
Scenario analysis trap
DeviceEvents logs process and security events on endpoints, but does not directly capture email link clicks. It is not used in an email click detection scenario.
Detailed technical explanation
How to think about this question
Under the hood, the join is typically performed on the `NetworkMessageId` field, which uniquely identifies an email message across both tables. The EmailEvents table includes the `DeliveryAction` field (e.g., 'Delivered') and the `ThreatTypes` field to confirm phishing. The UrlClickEvents table includes the `Url` and `IsClicked` fields to confirm the user clicked the link. In a real-world scenario, the analyst might also filter by `Timestamp` to ensure the click occurred after delivery, and use `ActionType` to exclude clicks that were blocked by Safe Links.
KKey Concepts to Remember
EmailEvents logs email delivery and processing details.
NetworkMessageId is a key identifier for correlating email events.
DeliveryLocation field indicates where an email was delivered (e.g., Inbox).
EmailEvents is foundational for email-related threat hunting and detection.
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
EmailEvents logs email delivery and processing details.
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.

Variation 1. A security analyst wants to create a custom detection rule in Microsoft 365 Defender Advanced Hunting that alerts when a user receives a phishing email and clicks a malicious link within 10 minutes. Which two tables must be joined in the KQL query?
easy
✓ A.EmailEvents and UrlClickEvents
✓ B.EmailEvents and DeviceEvents
C.EmailAttachmentInfo and UrlClickEvents
D.EmailPostDeliveryEvents and DeviceNetworkEvents
Why A: To detect a user receiving a phishing email and clicking a malicious link within 10 minutes, you need to correlate the email delivery event with the click action. The EmailEvents table contains records of email delivery (including sender, recipient, and subject), while the UrlClickEvents table logs when a user clicks a link in an email, including the URL and timestamp. Joining these two tables on a common identifier (such as NetworkMessageId) allows you to filter for clicks that occur within 10 minutes of email delivery, satisfying the detection requirement.
Variation 2. 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?
hard
A.EmailEvents and DeviceNetworkEvents
✓ B.EmailEvents and UrlClickEvents
C.EmailEvents and IdentityLogonEvents
✓ D.UrlClickEvents and DeviceNetworkEvents
Why B: 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.
