While installing patches, a systems administrator is disconnected from a server. The administrator attempts to ping the server and receives no response. Which of the following tools is MOST likely…

RDP connects to the Windows desktop session and requires the OS to be running and reachable over the network - neither of which is true if the server is unresponsive.

iLO is a dedicated out-of-band management processor with its own network port and firmware, separate from the main OS. When a patch installation renders the OS unresponsive or the server fails to respond to pings, iLO still allows the administrator to connect to a virtual console, view the server state, and recover the system without physical access.

VNC relies on a software agent running inside the OS and an active network connection, both of which are unavailable when the server does not respond to pings.

SSH requires the OS network stack to be operational and a running SSH daemon, making it unusable when the server is non-responsive to basic ping requests.
