To determine the correct script, we evaluate the following requirements:
* The script must search for the IP address 192.168.100.100.
* The output should be written to a file named parsed_host.log.
* The matching lines should be printed to the console.
Analysis of the options:
* Option A: Correct IP regex used and correct output filename, but reads from parsed_host.log instead of a source log file like test_log.log (not ideal for initial parsing).
* Option C: The IP address used is 192.168.100.101 instead of 192.168.100.100 - incorrect.
* Option D: Same IP address and logic as Option B, but uses print statement without parentheses, which is not valid in Python 3 unless using Python 2 - not ideal.
#Option B:
* Uses correct IP: "192.168.100.100"
* Reads from test_log.log (presumably the source log file).
* Writes to output/parsed_host.log.
* Prints each matching line and writes to output file - satisfying all conditions.
Reference:CyberOps Technologies (CBRFIR) 300-215 study guide, Chapter on "Investigating Host-Based Evidence and Logs" emphasizes scripting log parsing tasks using Python's regex and file I/O for filtering artifacts like IP addresses. Scripts should ensure proper source log input, pattern matching, result redirection, and optional output logging for forensics analysis.
