Which of the following would you use to remotely access a virtualization host in a secure fashion?

Using HTTPS to remotely access a virtualization host in a secure fashion is appropriate because HTTPS (Hypertext Transfer Protocol Secure) is designed to provide a secure communication channel over a computer network. It utilizes encryption, through protocols like SSL/TLS, which ensures that data transmitted between the client and the server is secure from interception and tampering. This is essential when managing sensitive information or configurations on virtualization hosts, as it protects against eavesdropping and unauthorized access.

In contrast, other methods fail to provide the necessary security measures. For example, Telnet transmits data in plaintext, making it vulnerable to interception, and is considered insecure for remote administration tasks. Ping, on the other hand, is a network utility primarily used for testing the reachability of devices on a network and does not facilitate secure remote access. Finally, accessing a virtualization host through a console port does not offer the same level of remote management as HTTPS and typically requires physical proximity to the hardware, which is impractical for remote access scenarios. Thus, HTTPS stands out as the preferred method for secure remote access.
