A team runs a KQL query to find the top 5 slowest API endpoints in Application Insights. Which KQL clause returns the top results?

  1. A LIMIT 5
  2. B TOP 5 BY duration
  3. C top 5 by duration desc (correct answer)
  4. D ORDER BY duration DESC LIMIT 5

Shortcut: KQL syntax: requests | summarize avg(duration) by name | top 5 by avg_duration desc. The top operator returns the N rows with the highest (or lowest with asc) values of the specified column.
