The answer is to create the watchlist first, then import a CSV file, followed by referencing the watchlist in a KQL query, and finally creating the scheduled analytics rule. This sequence is correct because a watchlist must exist as a data container in Microsoft Sentinel before you can upload data into it or query it; the KQL query uses the _GetWatchlist() function to pull the watchlist data, and the analytics rule cannot reference the watchlist until both the watchlist and the query are prepared. On the SC-200 exam, this task tests your understanding of the dependency chain in Sentinel’s watchlist workflow—a common trap is trying to write the KQL query before the watchlist alias exists, which causes a query failure. To remember the order, use the mnemonic “C-I-R-R”: Create the watchlist, Import the CSV, Reference it in KQL, then Run the rule.
SC-200 Mitigate threats using Microsoft Sentinel Practice Question
This SC-200 practice question tests your understanding of mitigate threats using microsoft sentinel. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A SOC analyst needs to create a custom watchlist in Microsoft Sentinel to use in an analytics rule. Order the following steps from first to last to correctly create and use the watchlist (Choose 4.)
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
1. Create a new watchlist in Microsoft Sentinel (e.g., from Sentinel > Watchlists > Add new).
Option A is correct because creating a new watchlist in Microsoft Sentinel is the initial step to define a custom data source for threat intelligence or reference data. This is done via Sentinel > Watchlists > Add new, where you specify the alias, description, and other metadata before uploading data. Without this step, there is no container to import the CSV file into, making it the logical first action.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates might think the KQL query must be written before importing the CSV, but the watchlist alias must already exist in Sentinel for the _GetWatchlist function to reference it correctly, making the import step second.
Detailed technical explanation
How to think about this question
The _GetWatchlist('WatchlistAlias') function in KQL retrieves the watchlist data as a dynamic table at query runtime, enabling real-time correlation against incoming events. Watchlists support up to 10 MB of data and can be updated manually or via automation, but the alias must match exactly between the watchlist creation and the KQL query. In a real-world scenario, an analyst might use a watchlist of known malicious IPs to enrich alerts without modifying the underlying analytics rule logic.

TExam Day Tips
→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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
