LPIC-1 System Architecture Practice Question
Which THREE of the following are characteristics of UEFI firmware compared to legacy BIOS? (Select exactly 3.)
⚠ Common exam trap
Watch out — candidates often confuse UEFI's support for GPT with MBR, incorrectly assuming UEFI still uses MBR for partition tables or boot loaders, leading them to select D or E as correct.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Supports booting from disks larger than 2 TB.
UEFI firmware uses the GUID Partition Table (GPT) instead of MBR, which supports 64-bit logical block addressing (LBA). This allows addressing disks larger than 2 TB, as the MBR scheme is limited to 32-bit LBA and a maximum addressable size of approximately 2.2 TB. Therefore, option A is correct.

Provides a graphical user interface during firmware setup.
Why this is correct
UEFI firmware often includes a GUI.
- ✓
Supports Secure Boot to prevent unauthorized operating systems from loading.
Why this is correct
Secure Boot is a feature of UEFI.
- ✗
Uses the Master Boot Record partition table.
