SK0-004 · Question #370
The Unified Extensible Firmware Interface (UEFI) allows:
The correct answer is A. the ability to boot from larger than 2GB disks. UEFI uses GPT partitioning to overcome the legacy BIOS MBR disk size limitation, enabling boot from disks larger than 2TB.

Why each option
UEFI uses GPT partitioning to overcome the legacy BIOS MBR disk size limitation, enabling boot from disks larger than 2TB.
UEFI replaces the legacy BIOS firmware interface and uses the GUID Partition Table (GPT) scheme instead of the old Master Boot Record (MBR), which removes the approximately 2TB maximum disk size limit. This allows systems to boot from and fully utilize large-capacity storage devices that MBR-based BIOS cannot address beyond that threshold.
UEFI is specifically designed to be CPU-architecture independent using EFI byte code - it is the opposite of CPU-dependent, unlike legacy BIOS which was tightly coupled to x86.
UEFI features an explicitly modular, extensible design that supports loadable drivers and EFI applications - it is not a non-modular design.
UEFI includes a built-in network stack that enables PXE network booting and remote firmware management, so it does have network capability.
