1. What are idempotent operations or commands in Ansible?
2. You want to set up passwordless authentication with your managed hosts. What steps should you follow?
3. What is the ad hoc command for checking communication with all your managed hosts?
4. Enumerate a few Ansible modules. Try to think of a configuration management scenario where you could use each module.
5. Think of a simple playbook that monitors the memory that’s available on your hosts and will notify you if that memory is above a given threshold.
