Regular expressions in Splunk are NOT case sensitive.
- True
- False
Correct Answer

A. False

Explanation

Regular expressions in Splunk are case sensitive. This means that when using regular expressions in Splunk, the pattern matching is sensitive to the case of the characters. For example, if a regular expression is used to search for the word "splunk" in a log file, it will only match instances of "splunk" with the same capitalization. If the word "Splunk" or "SPLUNK" is present in the log file, it will not be considered a match. Therefore, the correct answer is False.
