Microsoft DevOps Engineer Expert AZ-400 Practice Question

You are troubleshooting performance issues in a web application instrumented with Application Insights. You must write a Kusto Query Language (KQL) statement that lists, for the last 30 minutes, the number of server requests that returned HTTP status codes between 500 and 599, grouped by operation_Name, and shows the operations that failed most often first. Which query meets the requirement?

  • requests
| where timestamp <= ago(30m) and resultCode >= 500
| summarize count() by bin(timestamp, 5m)
| order by timestamp asc

  • requests
| where timestamp >= ago(30m) and toint(resultCode) >= 500
| summarize Failed=count() by operation_Name
| order by Failed asc

  • requests
| where timestamp >= ago(30m) and toint(resultCode) between (500 .. 599)
| summarize Failed=count() by operation_Name
| order by Failed desc

  • requests
| where timestamp between (now() .. ago(30m)) and resultCode in (500,501,502,503,504,505)
| summarize count() by operation_Name
| sort asc by count_
