Question 120/154
A Linux server was recently updated. Now, the server stops during the boot process with a blank screen and an f prompt. Which of the following is the most likely cause of this issue?
Correct Answer: B
Explanation
The most likely cause of this issue is that the UEFI boot was interrupted by a missing Linux boot file. UEFI (Unified Extensible Firmware Interface) is a standard that defines the interface and functionality of the firmware that initializes the hardware and software components of a system before loading the operating system. UEFI boot is a process that uses UEFI firmware to load and execute a boot loader, which is a program that loads the operating system kernel and other essential files. A Linux boot file is a file that contains information and instructions for the boot loader, such as the location of the kernel, the root file system, and the boot parameters. If a Linux boot file is missing or corrupted, the boot loader cannot find or load the kernel, and the system stops during the boot process with a blank screen and an f prompt.
