providing language that allows to describe in a declarative fashion a
desired state of IT application infrastructure.

Ansible Playbooks are written in... - Answer✔️✔️-YAML

What does it mean that Ansible is indempotent? - Answer✔️✔️-You can
safely run a playbook on the same hosts multiple times. When your
systems are in the correct state, the playbook makes no changes when you
run it. Not every module adheres to that out of the box.

How to register new RHEL for subscription? - Answer✔️✔️-Usually two
commands are used to do that:



1. subscription-manager register --username=youruser --
password=yourpwd

2. subscription-manager --attach --pool=poolID



Where pools and their IDs can be viewed by:



subscription-manager list --available

Python (at least 3.5 or 2.7) - can be "platform-python" pkg

2. "ansible-core" package installed on control node

What is Ansible Inventory? And what types are there. - Answer✔️✔️-
