A critical server has stopped responding in a distant location where there are no remote technicians to check the condition of the server. Which of the following can assist in checking the condition…

VNC requires the server OS and a running graphical desktop session to be accessible, making it unreliable when the server has stopped responding.

Bootstrap Protocol (BOOTP) is used for diskless clients to obtain IP addresses and boot images over a network - it is not a server diagnostics or remote management tool.

iDRAC is Dell's out-of-band management solution that is functionally equivalent to ILO but proprietary to Dell hardware; the question tests knowledge of ILO as the correct out-of-band tool in this context.

Remote Desktop Protocol (RDP) requires Windows OS with Remote Desktop Services actively running and reachable, which is unavailable when the server has stopped responding.

SSH (Secure Shell) provides encrypted remote command-line access to the server OS, allowing an administrator to run diagnostic commands, review logs, and check system status securely from a remote location.

ILO (HP Integrated Lights-Out) is an embedded out-of-band management controller that operates independently of the server's main OS, enabling hardware health monitoring, virtual console access, and remote power control even when the primary OS is unresponsive.
