Full question →mediummultiple choiceObjective-mapped
A SOC analyst in Microsoft Sentinel is creating a scheduled analytics rule to detect sign-ins from IP addresses known to be associated with a threat actor. The list of threat actor IPs is maintained in a custom Microsoft Sentinel watchlist and is updated daily. The analyst wants the rule to query the SigninLogs table and compare the IP address against this list. What is the most efficient way to reference the list in the KQL query?
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
Distractor review
Use the externaldata operator to read from a blob storage URL.
Externaldata reads data from external sources at query time, but it is not the recommended approach for frequently updated reference data in Sentinel, as it relies on external storage and can be slower.
B
Distractor review
Use the let statement to define a static list inline.
A let statement defines a static list that would require manual updates to the rule's query whenever the list changes, making it inefficient for daily updates.
C
Best answer
Use the _GetWatchlist() function to retrieve the watchlist.
_GetWatchlist() is the built-in function to retrieve watchlist data. It efficiently caches the data and automatically reflects updates without changing the rule query.
D
Distractor review
Use the datatable operator to define the list directly in the query.
Datatable defines a static table inline, similar to let, and would require manual updates to the query each time the list changes.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.

FAQ
Questions learners often ask
What does this SC-200 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Use the _GetWatchlist() function to retrieve the watchlist. — The _GetWatchlist() function is designed specifically to retrieve data from a Microsoft Sentinel watchlist. Watchlists are optimized for this purpose and can be updated independently without modifying the analytics rule. Using externaldata or datatable would be less efficient and harder to maintain.
