A remote Linux server requires an IP address change before being moved to a new datacenter. The server does not have X installed on it. Which of the following is an administrator MOST likely to use…

SSH (Secure Shell) is a text-based remote administration protocol that operates over port 22 and requires no graphical interface on the target system. Because the server lacks X (the X Window System), any GUI-dependent tool is unavailable, making SSH the appropriate and standard choice for a Linux administrator to log in and edit network configuration files.

RDP (Remote Desktop Protocol) is a Windows-specific graphical remote access protocol and is not natively available or appropriate for Linux server administration in this context.

VNC (Virtual Network Computing) requires a running graphical desktop environment, which depends on the X Window System - the very component stated to be absent on this server.

FTP (File Transfer Protocol) is used for file transfers only and does not provide an interactive shell or the ability to run administrative commands on a remote system.
