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.

SourceTypical use
Role defaults (defaults/main.yml)Lowest-precedence, overridable fallback values.
Inventory / group_vars / host_varsEnvironment- or host-specific settings.
Play vars / vars_filesValues scoped to a specific playbook run.
Registered variables (register)Output captured from a previous task.
FactsAuto-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.

Which variable source generally has the highest precedence?
What captures a previous task's output into a variable?
