Which stanza correctly matches the file /var/log/www1/secure.log?

The selected answer accurately identifies the specific path to the log file in question. By using the exact file path with the file extension included, this stanza directly corresponds to the desired log file, /var/log/www1/secure.log.

In Splunk, the monitor stanza is designed to specify the exact location of files you want to monitor for data ingestion. By providing the complete and precise path along with the exact filename, Splunk is able to monitor that specific log for any new entries or changes. This targeted approach ensures that only the intended file is processed, which is essential for efficient data management and analysis.

The other options do not reference the specific log file correctly. They either use wildcard characters that can lead to a broader selection of files or specify different paths altogether, which would not yield monitoring of the intended secure.log file at /var/log/www1. Hence, the selected answer is the most accurate representation for monitoring that particular log file.
