Question No. 3
A server administrator recently installed a kernel update to test functionality Upon reboot, the
administrator determined the new kernel was not compatible with certain server hardware and was
unable to uninstall the update. Which of the following should the administrator do to mitigate
further issues with the newly instated kernel version?
Select one option, then reveal solution.

Option A feels like the most precise fix here. By explicitly telling the bootloader which kernel to load first, you avoid any risk of it accidentally booting into the incompatible one. Just moving the stanza down (C) might work but isn’t a guaranteed solution since some bootloaders always load the first entry regardless of order changes. Reinstalling the OS (B) seems like overkill and setting a BIOS password (D) won’t solve the kernel issue at all. So, editing the bootloader config to point directly at the last good kernel is the best move to get back to a stable state quickly.

It’s A. Changing the first kernel stanza to point directly at the known-good kernel is the safest way to ensure the system boots correctly without guesswork. Just moving entries around might not guarantee the right kernel loads.

Probably C makes sense too since rearranging the boot order in the bootloader should let you boot the stable kernel without editing exact paths. It’s a simpler fix than rewriting the config completely.

Maybe D is irrelevant here since the issue is about kernel compatibility, not unauthorized access. Between A and C, I’m wondering if just moving the new kernel stanza to the end (C) is enough to boot the previous kernel reliably? Or does the bootloader config need to point explicitly to a known-good kernel, like in A? Also, would the question’s context imply GRUB is used, and if so, which version? That might affect how these changes work.
