A server with a UEFI motherboard fails to boot after a kernel update. The administrator needs to temporarily boot the previous kernel to restore service. Which action should be taken at the GRUB menu?

Run 'grub-mkconfig' from the GRUB rescue shell to regenerate entries with the old kernel.

Press 'e' on the default entry and change the root= parameter to point to the old kernel.

Select the 'Advanced options for Ubuntu' submenu and choose the previous kernel entry.

Type 'oldkernel' at the GRUB command line to load the previous kernel automatically.

A SysVinit system's /etc/inittab has been modified to change the default runlevel. After reboot, the system still boots to the old runlevel. What is the most likely cause?

The init process was not restarted after the change.

The kernel command line specifies a runlevel that overrides /etc/inittab.

The /etc/inittab file has incorrect permissions.

The /etc/rc.d/ directory has incorrect symlinks.

What is the primary purpose of an initramfs?

To store the kernel image itself

To hold user data and documents

To provide a temporary root filesystem with necessary drivers and tools to mount the real root filesystem

To provide a permanent root filesystem
