DevOps / Ansible Interview questions

What are the types of variables in Ansible?

Ansible pulls variables from many possible sources, each with a different scope and precedence.

Source	Typical use
Role defaults (`defaults/main.yml`)	Lowest-precedence, overridable fallback values.
Inventory / group_vars / host_vars	Environment- or host-specific settings.
Play vars / vars_files	Values scoped to a specific playbook run.
Registered variables (`register`)	Output captured from a previous task.
Facts	Auto-discovered host information.
Extra vars (`-e` on the command line)	Highest-precedence, runtime overrides.

Understanding which source wins matters because the same variable name can be set in several places at once; Ansible resolves this through a well-defined precedence order rather than "last one wins" by file position alone.
