Unified Extensible Firmware Interface (UEFI)

5 minutes 5 Questions

The Unified Extensible Firmware Interface (UEFI) is a modern replacement for BIOS, acting as a software interface between a computer's operating system and firmware. Serving the same purpose as BIOS, UEFI provides additional functionality and improvements, such as a graphical user interface, mouse …

Question 1

A user needs hardware-based encryption for their SSD. Which UEFI feature should be enabled?

Correct Answer: Self-Encrypting Drive

The user needs hardware-based encryption for their SSD. Self-Encrypting Drive (SED) is a feature supported by some SSDs that provides hardware-based encryption. It encrypts all data stored on the drive automatically, providing data security. Secure Boot ensures that only trusted software can run during the boot process, but does not provide encryption. Virtualization allows running multiple operating systems on the same hardware, but is unrelated to encryption. Setting a UEFI password protects UEFI settings, but does not encrypt the SSD. Therefore, enabling the Self-Encrypting Drive feature in UEFI is the correct solution for hardware-based SSD encryption.

Question 2

To mitigate the risk of 'Evil Maid' attack, which BIOS setting should you enable?

Correct Answer: Secure Boot

An Evil Maid attack allows unauthorized access to a system. Enabling Secure Boot ensures that the OS bootloader is digitally signed and prevents an attacker from replacing or modifying the boot process with malicious software.

Question 3

A user has just installed a second hard drive in their computer. Which UEFI setting should be adjusted to ensure the new hard drive is recognized?

Correct Answer: SATA configuration

Adjusting the SATA configuration in UEFI ensures that the new hard drive is properly detected and available to the system.
