BIOS/UEFI Flashcards
If the date and time on a system keeps being reset and not saving, what could be the issue?
The CMOS is failing.
What is POST?
Is the BIOS testing the PC if all is working. The beep. If not working then lots of beeps depending on the error.
What is UEFI?
Supports 64 bit and a GUI, is a new version of BIOS with better security.
UEFI supports drive sizes upto 9 zettabytes. UEFI provides faster boot time. Easier to update and change. Larger ROM.
Which option would you MOST likely use to configure PXE to set up remote imaging on a computer during a deployment?
To configure a computer to utilize the PXE boot option, you need to configure it under the BIOS boot option. The Preboot Execution Environment (PXE) is an industry-standard client/server interface that allows networked computers that are not yet loaded with an operating system to be configured and booted remotely by an administrator. Secure boot is a security system offered by UEFI that is designed to prevent a computer from being hijacked by malware. Power management allows Windows to reduce or turn off the power supplied to hardware components to save energy.
A customer wants to enable TPM to add password protection as the system boots up for an added security layer. Which of the following should you check to determine if TPM is enabled on the system?
You should check the BIOS settings to ensure that TPM (Trusted Platform Module) is enabled. TPM enables a system to encrypt the contents of the HDD/SDD and will require a password to be entered during the boot process for the HDD/SDD to be decrypted. A Trusted Platform Module (TPM) is a specialized chip on an endpoint device that stores RSA encryption keys specific to the host system for hardware authentication.
What is the purpose of utilizing secure boot?
The purpose of Secure Boot is to prevent malicious and unauthorized apps from loading into the operating system (OS) during the startup process. Secure Boot is enabled by default in Windows 10. When the PC starts, the firmware checks the signature of each piece of boot software, including UEFI firmware drivers (also known as Option ROMs), EFI applications, and the operating system. If the signatures are valid, the PC boots and the firmware gives control to the operating system. The OEM can use the firmware manufacturer’s instructions to create Secure boot keys and store them in the firmware.
