An administrator receives an alert that a server in a remote, lights-out data center is unresponsive. Standard remote management tools that rely on the operating system, such as RDP and SSH, are failing to connect. The administrator is able to connect to the server's baseboard management controller (BMC).
To diagnose a potential pre-boot issue, the administrator needs to view the server's graphical display output as if they were physically in front of it. Which of the following tools should the administrator use?
The correct answer is the virtual administration console. This tool, provided through the server's baseboard management controller (BMC), offers out-of-band remote keyboard, video, and mouse (KVM) functionality. It allows the administrator to view the server's graphical output from the moment it powers on, making it possible to interact with the BIOS/UEFI and diagnose errors that occur before the operating system loads.
Remote Desktop Protocol (RDP) is an incorrect choice because it is an in-band management tool that requires the server's operating system to be fully booted and operational.
A crash cart is a physical cart with a keyboard, monitor, and mouse used for direct, local hardware access. It is not a viable solution for a remote data center.
Serial-over-LAN (SoL) provides text-based command-line access to the server's serial port over the network. It would not display the full graphical output needed to interact with modern BIOS/UEFI interfaces or see graphical boot errors.
