Dive Into Ansible - From Beginner to Expert in Ansible - Configuring Secure Shell (SSH) Connectivity between Hosts

The video tutorial explains how to configure SSH connectivity between hosts using Ansible, an agentless architecture. It covers the process of establishing secure SSH connections, verifying fingerprints, and managing SSH keys for passwordless authentication. The tutorial also demonstrates automating SSH key distribution using SSH pass and scripts, and concludes with testing Ansible connectivity and configuration.

What is a key feature of Ansible's architecture?

• It only works with Windows systems.

• It uses a centralized server for all operations.

• It requires agents on target hosts.

• It is agentless, requiring no software on target hosts.

What happens if the protocol versions between client and server are incompatible during SSH session establishment?

• The connection is established with a warning.

• The connection is terminated.

• The client automatically updates its protocol version.

• The server downgrades its protocol version.

What algorithm is used for session key negotiation in SSH?

• Diffie-Hellman

• AES

• RSA

• SHA-256

Where is the target fingerprint stored after verification in SSH?

• In the client's authorized keys file

• In the server's known hosts file

• In the server's authorized keys file

• In the client's known hosts file

What is the purpose of the authorized keys file in SSH?

• To store private keys

• To store encrypted passwords

• To store session keys

• To store public keys of trusted hosts

What tool is used to efficiently copy public keys to remote systems?

• SSH Copy ID

• SSH Agent

• SSH Pass

• SSH Keygen

What does the SSH pass tool help automate?

• Updating SSH protocol versions

• Generating SSH keys

• Copying private keys

• Entering passwords for SSH commands

Which command is used to test connectivity to all hosts in Ansible?

• ansible-executable

• ansible-ping

• ansible-test

• ansible-connect

What does the '-m' flag specify in an Ansible command?

• The module to use

• The inventory file

• The verbosity level

• The target host

What is the purpose of the 'all' group in Ansible?

• To specify all available modules

• To target all hosts in the inventory

• To configure all network settings

• To list all SSH keys
