Question 8
UnclassifiedA remote DGX node has a kernel panic and the OS is completely frozen. You need to capture a screenshot of the console output to see the panic message before rebooting.
Correct answer: A
Explanation
ipmitool can access the server’s out-of-band management interface and view the remote console even when the OS is frozen. That lets you capture the panic text before rebooting, since the console is available independently of the operating system.
Why each option is right or wrong
A. ipmitool
IPMI 2.0 defines a separate out-of-band management channel, so the BMC can still provide Serial-over-LAN and remote KVM/console access even when the host OS has panicked and is unresponsive. Using `ipmitool` against the BMC lets you view the live console output before rebooting, which is exactly what is needed here because the frozen kernel prevents any in-band SSH or local OS-based capture.
