Social Security Numbers (PII) data is found in log events, which is against company policy. SSN format is as follows: 123-44-5678. Which configuration file and stanza pair will mask possible SSNs in…

props.conf can reference a transforms stanza to invoke masking, but it does not contain the masking regex or replacement logic itself.

props.conf serves the same role as choice A - it references transforms but does not define the masking operation.

This choice represents transforms.conf with an incorrect or incomplete stanza configuration; the correct answer D specifies the proper stanza type (e.g., SEDCMD or REGEX with DEST_KEY) required for masking.

transforms.conf is where the actual masking logic is defined; a stanza using SEDCMD with a regex matching the SSN pattern (e.g., \d{3}-\d{2}-\d{4}) rewrites the _raw field to replace SSNs with a placeholder. The stanza is referenced from props.conf via a TRANSFORMS- setting, but the masking rule itself resides in transforms.conf.
