A
To find the total number of file uploads by all users in the last 30 days
Why wrong: The query filters by a specific user.
B
To find files larger than a certain size uploaded by a specific user
Why wrong: There is no file size filter in the query.
C
To list all files deleted by a specific user in the last 30 days
Why wrong: The query filters for uploads, not deletions.
D
To identify file types that a specific user uploaded more than 10 times in the last 30 days
The query groups by file type and counts only those with count > 10.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
To identify file types that a specific user uploaded more than 10 times in the last 30 days
The KQL query uses `| summarize Count = count() by FileType` to group audit log entries by file type, then `| where Count > 10` filters for file types that appear more than 10 times. The `where UserId == 'user@domain.com'` restricts the results to a specific user, and `| where TimeGenerated > ago(30d)` limits the time range to the last 30 days. This directly identifies file types uploaded more than 10 times by that user, matching option D.
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 may misread the query as counting total uploads (option A) or listing files (option C), but the `summarize by FileType` and `where Count > 10` clearly indicate aggregation by file type with a frequency threshold, not a simple list or total count.
Detailed technical explanation
How to think about this question
Under the hood, Microsoft Purview Audit logs each user action as an event with properties like `UserId`, `Operation`, `FileType`, and `TimeGenerated`. The `summarize` operator in KQL aggregates these events by file type, and the `count` function tallies occurrences. A real-world scenario is identifying shadow IT or data exfiltration patterns, where a user uploading many files of a specific type (e.g., `.zip` or `.pdf`) could indicate policy violations.

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.
