After completing initial diagnostic procedures and allocating system resources, a 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 the CMOS setup utility. This option is commonly referred to as a:
- Boot record
- Master Boot Record (MBR)
- Partition table
- Boot sequence
Boot sequence

Chassis intrusion detection is an option that can be enabled/disabled in BIOS setup utilities that come equipped with this feature. Coupled with a hardware sensor mounted inside a computer case, it can be used to check whether the case was opened and display a notification alert during next boot.
True or False?
True
A 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:
- Viewing a detailed information related to CPU, RAM, and HDDs
- Enabling/disabling integrated hardware interfaces, such as USB, Audio, NIC, TPM, or integrated graphics controllers
- Configuring the parameters of CPU, RAM, and HDDs
- Enabling/disabling certain functionalities, e.g. virtualization support
- All of the above
All of the above
Which type of password provides the highest level of permissions in BIOS?
- root
- Supervisor
- Administrator
- Power User
Supervisor
A computer that supports LoJack technology must have two main components installed. It needs an Application Agent (residing in the OS), which sends tracking signals that enable location and recovery of a stolen device. The other component is a Persistence Module, which restores the Application Agent and allows it to survive reinstallation of an operating system or reformatting of the hard drive. The highest level of security offered by LoJack can be achieved when Persistence Module resides in the:
- OS
- USB key
- Computer’s BIOS
- Partition gap on the hard drive
Computer’s BIOS
The UEFI functionality designed to prevent loading of malware and/or unauthorized OSs is called:
- LoJack
- Bitlocker
- Secure boot
- Kerberos
Secure boot
The CMOS battery located on a computer’s motherboard allows for maintaining the correct time and date information stored in CMOS RAM. In older computer systems, the CMOS battery also allowed for maintaining the BIOS configuration settings stored in CMOS RAM.
True or False?
True
Which of the following is a common solution for BIOS time and setting resets?
- Windows Update
- Primary storage module replacement
- Safe mode troubleshooting
- CMOS battery replacement
