LX0-103 · Question #87

Which of the following information is stored within the BIOS? (Choose TWO correct answers.)

The correct answer is A. Boot device order D. Hardware configuration. The BIOS (stored in CMOS) holds firmware-level hardware settings such as boot device order and hardware configuration, not OS-level or software data.

Why each option

The BIOS (stored in CMOS) holds firmware-level hardware settings such as boot device order and hardware configuration, not OS-level or software data.

ABoot device orderCorrect

The BIOS setup stores the boot device priority sequence in non-volatile CMOS RAM so the firmware knows which device to try first when initializing POST and handing off to a bootloader.

BLinux kernel version

The Linux kernel version is part of the operating system software and is stored on disk; the BIOS has no knowledge of or storage for OS-level software versions.

CTimezone

Timezone is an operating system or application-level setting stored in files such as /etc/timezone; the BIOS only tracks the hardware clock value, not the timezone interpretation.

DHardware configurationCorrect

The BIOS retains hardware configuration settings such as CPU parameters, memory timing, enabled/disabled onboard controllers, and virtualization flags, which the firmware uses to initialize hardware before the OS loads.

EThe system's hostname

The system hostname is configured within the OS (e.g., /etc/hostname) and is never stored in BIOS firmware.
