D.

^File: Clean$

Answers
D.

^File: Clean$

Suggested answer: A

Explanation:

A regular expression (regex) is a sequence of characters that defines a search pattern for text. A regex can be used to extract custom properties from log messages or events in a SIEM platform. In this case, the regex that matches the phrase ''File: Clean'' exactly is ^File: Clean$. The ^ symbol indicates the beginning of the line and the $ symbol indicates the end of the line. The regex ensures that no other characters are before or after the phrase.Reference:
