Exam DP-700 topic 3 question 12 discussion

B is the answer SELECT * FROM queryinsights.exec_requests_history WHERE start_time >= DATEADD(MINUTE, -30, GETUTCDATE()) AND login_name = USER_NAME();

SELECT * FROM queryinsights.exec_requests_history WHERE start_time >= DATEADD(MINUTE, -30, GETUTCDATE()) AND login_name = USER_NAME();

I think both [queryinsights].[exec_requests_history] and Query activity can match "username of the users that submitted the queries and the query statements". However, query activity just can set filter on "last 24 hours", "last 7 days" and "last 30 days", the question need filter it with last 60 minutes. [queryinsights].[exec_requests_history] is easy to set filter with where condition on submit time column.
