Question 10

Correct answer: A

A.

This Ansible playbook automates the configuration of rsnapshot to create daily backups of the /var/log directory, retaining backups for 7 days. It ensures the required rsnapshot package is installed, configures rsnapshot using a template file, and schedules a daily cron job to run the backup process. By automating this setup, the playbook simplifies backup management and ensures consistency across multiple servers, providing a reliable solution for log file archiving and retention.
