    A system administrator needs to create a maintenance script for an Arista switch. The script must archive any log file in /mnt/flash/log/ that ends with .log, is older than 7 days, and is larger than 1 megabyte. The archiving process involves compressing the file with gzip and appending a .gz extension. Which of the following command pipelines correctly and efficiently performs this task? (Select TWO).

    flowchart TD Start([Start]) --> FindFiles{Find files in /mnt/flash/log/: - name ends in .log - older than 7 days - larger than 1MB} FindFiles -->|For Each File| Gzip[Compress with gzip] Gzip --> End([End])

    Correct answer: A, C

    This is a correct and common solution. -exec runs the gzip command for each file found. The {} is replaced by the filename, and \; terminates the command. While correct, it can be inefficient as it forks a new gzip process for every single file.

    This is a more robust and efficient solution. The -print0 option in find separates filenames with a null character, and xargs -0 reads null-separated input. This correctly handles filenames that contain spaces or other special characters. xargs also batches multiple filenames into a single gzip command, making it more efficient than -exec for a large number of files.
