How do I fix 'UNREACHABLE' errors in Ansible?

Check network connectivity with ping or nc, verify SSH key permissions are set to 600, and ensure the correct IP or hostname is defined in your inventory.

What do the different Ansible verbosity levels do?

-v shows task results, -vv shows input parameters, -vvv shows SSH connection details, and -vvvv provides full plugin internals for deep debugging.

How can I test an Ansible playbook without making changes?

Use the 'ansible-playbook --check' command to perform a dry run, which simulates changes without applying them to the target system.

What is the best way to debug undefined variables?

Use the 'ansible.builtin.debug' module to print variable values or apply the 'default()' filter to provide a fallback value if a variable is missing.

How do I handle missing sudo passwords in a playbook?

You can either run the playbook with the '--ask-become-pass' flag or configure 'NOPASSWD' for the user in the target host's /etc/sudoers file.
