Question 1hardmultiple choice
Full question →hardmultiple choiceObjective-mapped
An analyst is creating a custom detection rule in Microsoft 365 Defender to detect lateral movement. The rule should trigger when a device (DeviceA) connects to another device (DeviceB) via SMB (port 445) and, within 5 minutes, a scheduled task is created on DeviceB. Which Advanced Hunting query pattern correctly correlates these events across devices?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
Join DeviceNetworkEvents (where RemoteIP is DeviceB's IP and RemotePort 445) with DeviceEvents (where ActionType == 'ScheduledTaskCreated' and DeviceId == DeviceB's ID) using a time window of 5 minutes
Correct. This joins the network connection from DeviceA with the scheduled task creation on DeviceB within the specified time window.
B
Distractor review
Use DeviceProcessEvents to find smb.exe on DeviceA, then join with DeviceFileEvents on DeviceB
DeviceProcessEvents logs process creation, not network connections; DeviceFileEvents does not contain scheduled task events.
C
Distractor review
Use only DeviceNetworkEvents on DeviceA and DeviceB separately
This would not capture the scheduled task creation event.
D
Distractor review
Use EmailEvents and DeviceEvents on DeviceB
EmailEvents is used for email delivery events, not network connections.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Technical deep dive
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.

Question 6
An organization uses Microsoft 365 Defender. A security analyst is investigating a malware incident on a user's device. The automated investigation and response (AIR) has already isolated the device from the network. The analyst now needs to collect a copy of a specific suspicious file from the device for further analysis. Which action should the analyst initiate from the device's entity page?
FAQ
Questions learners often ask
What does this SC-200 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Join DeviceNetworkEvents (where RemoteIP is DeviceB's IP and RemotePort 445) with DeviceEvents (where ActionType == 'ScheduledTaskCreated' and DeviceId == DeviceB's ID) using a time window of 5 minutes — To correlate events from two different devices, you must join the DeviceNetworkEvents table (for SMB connections from DeviceA to DeviceB) with the DeviceEvents table (for scheduled task creation on DeviceB). The join is performed on DeviceB's DeviceId and within a time window. DeviceProcessEvents does not capture network connections; DeviceFileEvents records file changes, not scheduled tasks.
