Designed as a replacement for BIOS

Network access

Question 12

After completing the initial diagnostic procedures and allocating system resources, the startup BIOS program checks for information about secondary storage devices that might contain the OS.

The list of devices and the order in which they should be checked can be found and arranged in BIOS.

This functionality can be accessed via:

Answer 12

Boot Options

Question 13

Which BIOS configuration option allows to mitigate the risk of malware infection?

Answer 13

USB configuration settings

Question 14

The BIOS configuration interface provides a wide range of advanced hardware-related options.

In modern PCs, depending on the specific BIOS type and version, these options might typically include:

Answer 14

Viewing a detailed information related to CPU, RAM, and storage media

Enabling/disabling integrated hardware interfaces, such as USB, Audio, NIC, TPM, or integrated graphics controllers

Configuring the parameters of CPU, RAM, storage media, and cooling fans

Enabling/disabling certain functionalities, e.g., virtualization support

Question 15

A UEFI functionality designed to prevent the loading of malware and unauthorized OSs is called:

Answer 15

Secure boot

Question 16

BIOS/UEFI passwords improve the security of a PC. These low-level passwords may, for example, prevent unauthorized users to proceed when the computer is powered on (Supervisor password), or restrict the scope of changes a user can make in the BIOS/UEFI interface (User password).
