A system administrator is working on a server that uses GRUB 2. They need to change the default boot entry to the third entry in the menu. Which command should they use to make this change persistent?

`grub2-mkconfig -o /boot/grub2/grub.cfg`

A system administrator is troubleshooting a server that will not boot. The system uses BIOS firmware and a single disk with MBR partitioning. The administrator boots from a rescue CD and examines the MBR with `fdisk -l /dev/sda`. The output shows that the first partition starts at sector 63. The administrator suspects the bootloader is not installed correctly. Which of the following is the most likely issue?

The first partition does not start at sector 2048.

The partition table is of type GPT, not MBR.

The MBR code is missing or corrupted.

The boot flag is not set on the first partition.

An administrator is configuring a server to boot a Linux kernel directly from the UEFI firmware, bypassing a traditional bootloader like GRUB 2. The kernel is compiled with EFI stub support. Where should the kernel file be placed to ensure the firmware can find it?

In the root directory of the EFI System Partition (ESP).

In a subdirectory of the EFI System Partition (ESP), such as `\EFI\linux\`.

In the `/boot` directory of the root filesystem.
