CET 1 901 Unit 1 Final Exam Study Guide (Obj. 1.1 - 1.3)

Which feature of the Basic Input/Output System (BIOS)/Unified Extensible Firmware Interface (UEFI) would you enable if you wanted to ensure the authenticity of the firmware and prevent pre-boot viruses from being launched?

• Secure Boot

• LoJack

• Trusted Platform Module (TPM)

• Redundant Array of Independent Disks (RAID) settings

What would the built-in firmware diagnostics of a system Basic Input/Output System (BIOS) allow you to do?

• Confirm the functionality of system components such as memory

• Detect intrusion by alerting the BIOS if the case cover is removed

• Scan for and recover bad sectors on a hard disk

• Enable or disable virtualization settings

Which is NOT one of the possible RAM settings you are able to modify within the BIOS of a computer?

• Increase RAM from 2048MB to 4096MB

• Adjust the voltage of RAM from 1.5v to 1.65v

• Increase the frequency of RAM from 540MHZ to 800MHZ

• Modify the memory multiplier from 6x to 12x

When someone refers to firmware, what are they talking about?

• Specialized software stored in memory chips that holds operating system (OS)-specific information

• The physical components that the device is made from

• An operating system such as Windows, Mac OS, or Linux

• A printed circuit board that can be installed into an expansion slot

Where is the system Basic Input/Output System (BIOS) actually stored?

• Resetting

• Booting

• Encrypting

What purpose does the power-on self-test (POST) program serve?

• Checking your hardware to ensure that everything is present and functioning properly

• Starting the most basic services of a computer system

• Storing operating system (OS)-specific information whether or not power to the computer is on

• Improving software interoperability and addressing the limitations of the Basic Input/Output System (BIOS)

What Basic Input/Output System (BIOS) setting would you need to change if you wanted the central processing unit (CPU) to operate faster than it was designed to run?

• Clock speed

• Virtualization support

• System cache

• System memory

Which of the following is unlikely to be displayed within typical system firmware monitoring capabilities?

• Device drivers

• Motherboard temperature
