Exam 200-301 topic 1 question 739 discussion

Ansible: - uses SSH (port 22) for remote device communication - uses YAML for fundamental configuration Chef: - uses TCP port 10002 for configuration push jobs - uses Ruby for fundamental configuration elements Puppet: - uses TCP 8140 for communication - fundamental configuration elements are stored in a manifest

Answer A sneaky question because you could make use of SSH universally in device configuration scenarios....but the keyword terminology here is "managed nodes" which is part of the Ansible architecture description....A is the most correct

Ansible uses SSH, which by default operates over TCP port 22, to communicate with managed nodes. SSH is a secure protocol that allows Ansible to remotely configure and manage devices or systems without the need for an agent on the target machine. Other Options: B. Python: Python itself is a programming language and does not inherently use a specific port like TCP 22 for configuration management or communication. C. Puppet: Puppet typically uses a custom agent-server architecture and communicates over TCP port 8140 by default, not port 22. D. Chef: Chef uses a client-server model where the clients (nodes) communicate with the Chef server over TCP port 443 (HTTPS) by default.

A is correct
