A Linux server was recently updated. Now, the server stops during the boot process with a blank screen and an £s> prompt. When of the following is the MOST likely cause of this issue?
正解:B
The most likely cause of this issue is that the UEFI boot was interrupted by a missing Linux boot file, such as grub.cfg or vmlinuz, which are essential for loading the Linux kernel and booting the system. The £s> prompt indicates that the system entered into UEFI Shell mode, which is a command-line interface for troubleshooting UEFI boot issues. The administrator can use UEFI Shell commands to locate and restore the missing boot file or change the boot order. Verified References: [UEFI Shell Guide]
