CompTIA Security+ Certification SY0-601: The Total Course - Chapter 4 Exam Question Review

The video tutorial explains how to set up SSH public key authentication on a Linux virtual machine. It begins with a scenario requiring SSH public key authentication instead of password authentication. The tutorial outlines the correct sequence of commands: generating a key pair with SSH Keygen, copying the public key to the server using SSH copy ID, and testing the setup. The process involves generating keys on a client machine, transferring the public key to the server, and verifying the authentication using the private key.
