Ansible for the Absolute Beginner - Demo - Ansible Inventory

The video tutorial demonstrates how to test connectivity between Ansible and target machines using SSH. It covers creating an Ansible inventory file, running a ping test, and troubleshooting connectivity issues related to SSH keys. The tutorial also discusses solutions for SSH key checking problems and emphasizes best practices for secure connectivity in production environments.

What is the first step to check connectivity between Ansible and a target machine?

• Run a ping test using Ansible

• Disable host key checking

• Create an Ansible playbook

• Manually SSH into the target server

What file is created to specify the target host details in an Ansible project?

• Playbook file

• Configuration file

• Log file

• Inventory file

What module is used in Ansible to perform a connectivity test?

• Service

• Ping

• Copy

• Shell

Why did the connectivity test fail for the second target server?

• Ansible configuration error

• SSH key fingerprint not added to known hosts

• Wrong password

• Incorrect IP address

What is one way to resolve the SSH key issue for the second target server?

• Use a different password

• Change the server's IP address

• Manually SSH into the server and accept the key

• Reboot the server

What is the recommended method for establishing connectivity in production environments?

• Manually adding keys to known hosts

• Using SSH keys

• Disabling host key checking

• Using passwords

What configuration change can disable host key checking in Ansible?

• Enable host key checking

• Uncomment the host key checking line and set it to false
