A DevOps engineer needs to run a batch job that processes a large file. The job must run in an isolated environment with a specific version of a library, and the engineer wants to avoid the overhead of a full virtual machine. Which approach is most efficient?

Install the library globally on the host and run the job directly.

Use a Python virtual environment on the host.

Create a new virtual machine with the library installed and run the job there.

Run the job in a Docker container built from an image with the required library version.

A Linux administrator needs to find all files under /var/log that were modified in the last 24 hours and are larger than 10 MB, then display the full path of each file. Which command-line approach accomplishes this?

find /var/log -type f -mtime -1 -size +10M -exec ls -l {} \;

du -ah /var/log | sort -nr | head -20

ls -lR /var/log | grep -E '^\-.*[0-9]{2}:[0-9]{2}'

grep -r -mtime -1 -size +10M /var/log
