A technician uses a method where each server is configured with a public/private encryption key pair and identified by a host key fingerprint. What is this method?

The correct answer is B. SSH.

SSH, or Secure Shell, is a method used to securely access and manage network devices and servers over an insecure network. It utilizes public/private key pairs for authentication, ensuring that only authorized users can gain access. The host key fingerprint helps verify the identity of the server to prevent man-in-the-middle attacks.
