Q&A

1. How does SSH connectivity works ?

The known_hosts file lets the client authenticate the server, to check that it isn't connecting to an impersonator. The authorized_keys file lets the server authenticate the user.

2. Location of Ansible Configuration Settings ?

Changes can be made and used in a configuration file which will be searched for in the following order:

• ANSIBLE_CONFIG - environment variable if set (Highest priority)
• ansible.cfg - in the current directory
• ~/.ansible.cfg - in the home directory
• /etc/ansible/ansible.cfg (Lowest priority)
