   A Splunk admin is troubleshooting a slow search that runs every hour against 30 days of data. The search first uses `top` to find the most common source types, then pipes the results into `stats count by sourcetype`. The admin notices the search takes over 10 minutes. Which change would MOST improve the search's performance?

   • AAdd `| fields sourcetype` before the `top` command to reduce the amount of data processed.
   • BAdd `index=_internal` to the search to ensure the search is running against a smaller, faster index.
   • CChange the search mode from smart to verbose to ensure all fields are available for the `top` command.
   • DReplace `top` with `stats count by sourcetype` and remove the initial `top` command.

   What is the primary purpose of a summary index in Splunk?

   • ATo store raw events in a compressed format to save disk space
   • BTo store pre-computed results of expensive searches so that later searches can use them
   • CTo replace the need for data models in all cases
   • DTo provide a faster way to search across multiple indexes simultaneously

   A Splunk admin is troubleshooting a slow search. The Job Inspector shows that the `search` phase is taking 80% of the total time, and the `results` phase is taking 15%. The search is `index=main | rex field=_raw "error=(?<error_code>\d+)" | stats count by error_code`. The admin wants to reduce the time spent in the `search` phase. Which change would be MOST effective?

   • AChange the search mode to fast to reduce the time spent in the search phase.
   • BAdd `error=*` to the search to reduce the number of events scanned.
   • CUse `| head 1000` before the `stats` command to reduce the data scanned.
   • DUse `| fields error_code` before the `stats` command to reduce the data scanned.

   A Splunk admin is optimizing a search that runs on a large dataset. The Job Inspector shows that the search is spending a significant amount of time in the 'search' phase and the 'results' phase. The search is `index=main | rex field=_raw "error=(?<error_code>\d+)" | stats count by error_code`. The admin wants to reduce the time spent in the 'search' phase. Which change would be MOST effective?

   • AMove the `rex` command before the `stats` command and use `rex` with `mode=sed` to extract the field during indexing.
   • BChange the search mode to fast to reduce the time spent in the search phase.
   • CUse `index=main error=* | rex field=_raw "error=(?<error_code>\d+)" | stats count by error_code`.
   • DUse `| rex field=_raw "error=(?<error_code>\d+)" | stats count by error_code` but add `| fields error_code` before the `stats` command.
