A Splunk admin is troubleshooting a slow search that uses a complex regex with multiple nested groups and alternations. The search processes millions of events and takes several minutes longer than expected. The admin suspects the regex is causing excessive backtracking. Which regex modification would most effectively improve performance?

Remove all anchors from the regex to allow more flexible matching

Use a greedy quantifier instead of a lazy quantifier

Replace nested groups with non-capturing groups and use atomic groups where possible

Add more alternation branches to cover additional edge cases

Which of the following is a method for extracting fields in Splunk?

Using the eval command to calculate fields

Using the table command to display fields

Using the rex command in a search

Using the stats command to aggregate fields

Which of the following is a technique to improve regex performance in Splunk?

Using complex patterns with many nested groups

Using anchors like ^ and $ to limit the search space

Using greedy quantifiers to match as much as possible

Using alternation with many alternatives

When using the Field Extractor to create a regex extraction, what does the Field Extractor use to generate the regular expression?

The examples you highlight in the event data

The host and source of the event

The index where the event is stored

A Splunk analyst needs to extract a field called 'status' from events that contain 'status=active' or 'status=inactive'. The analyst wants to use the rex command and is concerned about performance. Which rex command is both correct and efficient?

| rex "status=(? active|inactive)"
