Note
This module is part of ansible-base and included in all Ansible installations. In most cases, you can use the short module name varnames even without specifying the collections: keyword. Despite that, we recommend you use the FQCN for easy linking to the module documentation and to avoid conflicting with other collections that may have the same module name.
