Question 1hardmultiple choice
Full question →hardmultiple choiceObjective-mapped
An analyst is investigating a sophisticated attack involving a compromised device. The analyst has identified a malicious process that spawned multiple child processes. The analyst wants to create a custom detection rule in Microsoft 365 Defender that alerts when a specific parent process creates a child process that makes an outbound network connection to any IP not in the organization's internal range. Which KQL query and rule type should the analyst use?
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
Create a custom detection rule (Advanced Hunting rule) with a query that joins DeviceProcessEvents and DeviceNetworkEvents, filtering for the parent process and external IP addresses
Correct. Custom detection rules in M365 Defender allow multi-table joins and scheduled alerting, exactly what this scenario requires.
B
Distractor review
Create a scheduled rule in Sentinel and export the data from M365 Defender
While Sentinel can also create scheduled rules, the question specifies creating a rule within Microsoft 365 Defender, not using Sentinel. Also, exporting data is unnecessary.
C
Distractor review
Use a custom detection rule with DeviceEvents only
DeviceEvents contains various events but not a comprehensive record of process creation and network connections. You need both tables.
D
Distractor review
Use a Microsoft Defender for Endpoint custom detection rule (built-in) that already detects child process connections
There is no built-in rule that matches this specific scenario; a custom rule is required.
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: Create a custom detection rule (Advanced Hunting rule) with a query that joins DeviceProcessEvents and DeviceNetworkEvents, filtering for the parent process and external IP addresses — Microsoft 365 Defender allows you to create custom detection rules from advanced hunting. These rules are essentially scheduled queries that can join multiple tables and generate alerts. To detect the described behavior, the analyst needs to join DeviceProcessEvents (to get parent-child process relationships) with DeviceNetworkEvents (to get outbound connections). Then filter for the specific parent process and for destination IPs outside the internal range. This complex query is best implemented as a custom detection rule, which supports scheduled execution and alerting. A simple scheduled rule is not available within M365 Defender; the equivalent is the custom detection rule feature. The other options are either incomplete or incorrect.
