A SOC analyst needs to write a KQL query for a Microsoft Sentinel scheduled analytics rule that detects impossible travel activity. The rule should alert when a user signs in from two different countries within 60 minutes. The analyst has the SigninLogs table with columns: UserPrincipalName, IPAddress, Location (country), TimeGenerated. Which KQL query pattern correctly triggers an alert for each pair of sign-ins meeting the condition?
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
Self-join SigninLogs on UserPrincipalName, where TimeGenerated difference < 60m and Location != Location, then summarize by bin(TimeGenerated, 1h).
This pattern correctly identifies pairs and can be used to generate an alert for each pair.
B
Distractor review
Use the `make_list()` function to aggregate all locations per user within a 60-minute window and check if the list has more than one distinct value.
This approach does not capture the time proximity between individual sign-ins; it could sign from two IPs 59 minutes apart but also from a third IP many days later if the bin is 1 hour, but the rule should trigger only when two sign-ins happen within 60 minutes of each other, not just within the same hour bin.
C
Distractor review
Use the `series_decompose()` function to detect outliers in location sequences.
Series decompose is for time series anomaly detection, not for simple impossible travel detection.
D
Distractor review
Use the `rolling_join()` function to compare each sign-in with the previous one per user.
There is no `rolling_join()` function in KQL. The correct approach is a self-join or using `prev()` with a time filter.
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: Self-join SigninLogs on UserPrincipalName, where TimeGenerated difference < 60m and Location != Location, then summarize by bin(TimeGenerated, 1h). — To detect impossible travel, you need to self-join the table to find pairs of sign-ins by the same user within a short time window from different locations. The `where` clause filters for time difference less than 60 minutes and different countries. The `| where` conditions ensure both events are considered. Other patterns like using a sliding window with `prev()` are possible but more complex and less readable.
