- A
Use DeviceLogonEvents and DeviceNetworkEvents with a join on DeviceId and a time range
DeviceLogonEvents provides logon data per device; DeviceNetworkEvents provides outbound connections. Joining by DeviceId within a short time after logon can reveal lateral movement via RDP.
- B
Use IdentityLogonEvents and DeviceNetworkEvents with a join on IP address
Why wrong: IdentityLogonEvents tracks cloud application logons, not interactive device logons, so it is not suitable for detecting lateral movement between workstations.
- C
Use DeviceProcessEvents and DeviceNetworkEvents with a join on DeviceId
Why wrong: DeviceProcessEvents captures process executions, but lateral movement is better identified through interactive logon events rather than process creation.
- D
Use EmailEvents and DeviceLogonEvents with a join on RecipientEmail
Why wrong: EmailEvents pertains to email messages and does not provide information about network connections or lateral movement.
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. A key principle to apply: deviceLogonEvents tracks interactive and network logons to endpoints.. 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 using advanced hunting in Microsoft 365 Defender to detect lateral movement. The analyst wants to find all devices where a specific user account had an interactive logon, and then identify which of those devices subsequently initiated outbound Remote Desktop Protocol (RDP) connections to other internal IP addresses. Which KQL approach is most efficient for this investigation?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Use DeviceLogonEvents and DeviceNetworkEvents with a join on DeviceId and a time range
Option A is correct because it uses DeviceLogonEvents to identify interactive logons for the specific user account on devices, then joins those results with DeviceNetworkEvents on DeviceId within a time range to find subsequent outbound RDP connections (destination port 3389) to internal IPs. This approach directly correlates the user's logon activity with network connections from the same device, which is the most efficient and precise method for detecting lateral movement via RDP.
Key principle: DeviceLogonEvents tracks interactive and network logons to endpoints.

- ✓
Use DeviceLogonEvents and DeviceNetworkEvents with a join on DeviceId and a time range
Why this is correct
DeviceLogonEvents provides logon data per device; DeviceNetworkEvents provides outbound connections. Joining by DeviceId within a short time after logon can reveal lateral movement via RDP.
Related concept

- ✗
Use IdentityLogonEvents and DeviceNetworkEvents with a join on IP address
Why it's wrong here
IdentityLogonEvents tracks cloud application logons, not interactive device logons, so it is not suitable for detecting lateral movement between workstations.
- ✗
Use DeviceProcessEvents and DeviceNetworkEvents with a join on DeviceId
Why it's wrong here
DeviceProcessEvents captures process executions, but lateral movement is better identified through interactive logon events rather than process creation.
- ✗
Use EmailEvents and DeviceLogonEvents with a join on RecipientEmail
Why it's wrong here
EmailEvents pertains to email messages and does not provide information about network connections or lateral movement.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse IdentityLogonEvents (cloud identity) with DeviceLogonEvents (device-level logon), leading them to choose Option B, but the correct approach requires device-specific logon data to correlate with network events on the same device.
Detailed technical explanation
How to think about this question
Under the hood, DeviceLogonEvents includes LogonType values such as 'Interactive' (LogonType 2) and 'RemoteInteractive' (LogonType 10) for RDP sessions, while DeviceNetworkEvents captures outbound connections with destination port 3389 for RDP. The join on DeviceId ensures that only the same physical device is considered, and a time range filter (e.g., within 1 hour after logon) helps distinguish lateral movement from unrelated connections. In a real-world scenario, an attacker might log on interactively to a workstation and then use RDP to pivot to a server, which this query would detect by correlating the user's logon with subsequent RDP outbound traffic.
KKey Concepts to Remember
- DeviceLogonEvents tracks interactive and network logons to endpoints.
- DeviceNetworkEvents records outbound and inbound network connections from devices.
- Joining tables on DeviceId is crucial for correlating events on the same machine.
- Time-based joins are essential for sequencing events in a lateral movement investigation.
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
DeviceLogonEvents tracks interactive and network logons to endpoints.
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.
