An administrator needs to reconfigure a Linux server's operating system. Which of the following tools can the administrator use to access a command shell over the network? (Select TWO).
The correct answer is A. Connect with SSH C. Connect with VNC. SSH provides encrypted command-line access over a network, while VNC provides graphical desktop access from which a terminal/shell can be launched. Both are valid tools for remote Linux shell access.

Why each option
SSH provides encrypted command-line access over a network, while VNC provides graphical desktop access from which a terminal/shell can be launched. Both are valid tools for remote Linux shell access.
SSH (Secure Shell) operates on TCP port 22 and opens an encrypted command shell session directly on the remote Linux host, making it the most common tool for remote CLI administration.
RDP (Remote Desktop Protocol) is a Microsoft protocol primarily used for Windows systems and is not a standard tool for accessing a Linux command shell.
VNC (Virtual Network Computing) transmits the graphical desktop over the network, allowing the administrator to open a terminal emulator and access a command shell remotely.
BASH is a shell interpreter that runs locally on the server - it is not a network access protocol and cannot establish a remote connection on its own.
FTP is a file transfer protocol used to move files between hosts, not to open an interactive command shell session.
