What kind of user permission restrictions can be set in BIOS? (Select all that apply)
Which of the following statements is true?
Which type of password provides the highest level of permissions in BIOS?
What is LoJack?
Which of the following terms refers to a technology that allows for storing passwords, certificates, or encryption keys in a hardware chip?
While trying to enable the entire drive encryption feature in Windows technician receives the following error message: "A compatible Trusted Platform Module (TPM) Security Device must be present on this computer, but a TPM was not found". Knowing that the system has a TPM chip installed, which of the following steps might help in solving this problem?
A computer supporting LoJack technology has two main components installed: an Application Agent residing in the operating system which sends tracking signals to the monitoring center allowing the law enforcement to locate and recover stolen device, and Persistence Module which restores the Application Agent and allows it to survive operating system re-installation or hard drive format. The highest level of security offered by LoJack can be achieved when Persistence Module resides in:
Which of the answers listed below describe(s) the features of UEFI? (Select all that apply)
Which of the answers listed below describe(s) the features of UEFI? (Select all that apply)
A UEFI functionality designed to prevent the loading of malware and unauthorized OSs during system start-up is known as:
Chassis intrusion detection is an option that can be enabled/disabled in the BIOS setup utility (if a BIOS comes equipped with this feature). Coupled with a hardware sensor mounted inside the computer case, this functionality can be used to check if the case was opened and display a notification alert during next boot.
A standardized specification of a motherboard (including its dimensions, supported power supply types, and layout of components) is known as the motherboard's:
Which of the following terms are used to describe a motherboard's size and purpose? (Select all that apply)
What is the most common motherboard type used in desktop PCs?
Which of the answers listed below refers to a VIA-proprietary low-power consumption SFF type motherboard known for industrial and embedded PC applications?
Low Profile Extended (LPX) and New Low profile eXtended (NLX) are motherboard form factors known for the usage of a riser card (daughterboard) inserted into a slot near the edge of the board. The main advantage of this type of design is that expansion cards that plug into a riser card on the LPX/NLX motherboard are parallel with the board which saves space and allows for a smaller system case.
Which of the following statements are true? (Select 3 answers)
Peripheral Component Interconnect (PCI) is an example of a parallel expansion bus (and a corresponding slot type) used for attaching hardware devices (in the form of an integrated circuit or expansion card) to the motherboard inside the computer case.
What are the characteristic features of conventional PCI? (Select all that apply)
The Peripheral Component Interconnect eXtended (PCI-X) is an advanced version of PCI which: (Select all that apply)

Motherboard slots that enable installation of dedicated graphics controllers include: (Select 2 answers)
Peripheral Component Interconnect Express (abbr. as PCIe) is a high-speed, serial expansion bus designed as a replacement for: (Select all that apply)
In PCIe architecture, a single full-duplex point-to-point serial communication path consisting of two pairs of wires (where one pair is used for transmitting data and the other pair for receiving data) is known as:
The PCIe labeling (×1, ×4, ×8, ×12, ×16 and ×32) refers to the number of communication links (lanes) available in different versions of the PCIe interface. The base value (x1) relates to the speed of a single lane expressed in MB/s. The multiplier (x) allows for easy calculation of the maximum throughput of the entire interface for a given PCIe variant.
Which of the values listed below refers to the speed of a single-lane (x1) PCIe v1.x link?
A single-lane (x1) PCIe v2.x link offers maximum throughput of up to:
Which of the following answers lists the speed of a single-lane (x1) PCIe v3.x link?
A type of PCI slot for expansion cards installed in laptops characterized by a much smaller form factor when compared to its desktop counterpart is called:
Which of the following slot types allows for adding primary storage modules to the motherboard?
Which of the answers listed below refer(s) to the features of a motherboard's CPU socket? (Select all that apply)
Which of the answers listed below refer(s) to the features of a motherboard's CPU socket? (Select all that apply)
Which of the following integrated circuit types defines the core functionality and capabilities of a motherboard?
In a northbridge/southbridge chipset computer architecture, the function of southbridge is to provide high-speed data links between CPU, RAM, and PCIe graphics controllers.
The term "northbridge" refers to a part of the computer chipset that controls peripheral buses used for connecting lower-speed I/O devices such as hard drives, keyboards, mice, PCI devices, as well as embedded hardware including BIOS, integrated graphics/audio, USB, or Ethernet interfaces.
