A security analyst is investigating a potential malware outbreak using Microsoft 365 Defender advanced hunting. The analyst wants to find all devices where a file with a specific SHA256 hash was first created and then later deleted, which may indicate a cleanup attempt. Which query pattern on the DeviceFileEvents table is appropriate?
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
DeviceFileEvents | where SHA256 == "<hash>" | summarize Actions = make_set(ActionType) by DeviceId | where Actions has_all ("FileCreated", "FileDeleted")
Correct. This query groups by DeviceId and checks that both 'FileCreated' and 'FileDeleted' actions exist in the set for that device, ensuring the file was both created and deleted.
B
Distractor review
DeviceFileEvents | where SHA256 == "<hash>" and ActionType == "FileDeleted" | project DeviceId
This only finds devices where the file was deleted, without confirming it was also created. It does not meet the requirement to find devices with both events.
C
Distractor review
DeviceFileEvents | where FileHash == "<hash>" | summarize Actions = make_set(ActionType) by DeviceId | where Actions has "FileCreated"
The correct column is SHA256, not FileHash (which is a higher-level property). Also, it only checks for creation, not deletion.
D
Distractor review
DeviceFileEvents | summarize by DeviceId, ActionType | where ActionType in ("FileCreated", "FileDeleted")
This does not filter by the specific SHA256 hash and does not ensure both actions occurred on the same device. It returns any device with any file create or delete, which is not targeted.
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.

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: DeviceFileEvents | where SHA256 == "<hash>" | summarize Actions = make_set(ActionType) by DeviceId | where Actions has_all ("FileCreated", "FileDeleted") — To find occurrences where a file with a given SHA256 was both created (ActionType = 'FileCreated') and later deleted (ActionType = 'FileDeleted') on the same device, you need to filter DeviceFileEvents for that hash and then use a 'where has' approach or a self-join. Option A directly joins the two actions by device, which efficiently identifies devices where both events occurred. Option B checks for any file associated with the hash, not requiring both create and delete. Option C uses hashes but not the SHA256 column. Option D requires both actions on the same device, which is correct but missing the SHA256 filter – not suitable.
