An analyst is investigating a ransomware outbreak using Microsoft 365 Defender Advanced Hunting. They need to find all devices where a file with the extension '.locked' was created within one hour after a known malicious process (e.g., 'ransomware.exe') was executed on the same device. Which two tables should be joined in the query? (Choose 2.)

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

DeviceProcessEvents

Correct. This table records process creation events, including the malicious executable.

B

Distractor review

DeviceNetworkEvents

This table logs network connections, not file creations or process events.

C

Best answer

DeviceFileEvents

Correct. This table records file creation, modification, and deletion events.

D

Distractor review

DeviceRegistryEvents

This table logs registry changes, not file creations.

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: DeviceProcessEvents — To correlate process execution with file creation on the same device, the DeviceProcessEvents table (for process execution) and the DeviceFileEvents table (for file creation) are required. The join can be performed on DeviceId and a time window. DeviceNetworkEvents deals with network connections, and DeviceRegistryEvents deals with registry modifications, neither of which is relevant for this pattern.
