Comptia A+ Certification Practice Test 2 (Exam 220-901)

Front 1

True of False?

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.

Back 1

True

Front 4

What is the most common motherboard type used in desktop PCs?

Back 4

ATX

Front 5

Which of the answers listed below refers to a VIA-proprietary low-power consumption SFF type motherboard known for industrial and embedded PC applications?

Back 5

Mini-ITX

Front 6

True or False?

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.

Back 6

True

Front 7

What does the term "bus" mean and what is the difference between a parallel and serial bus?

Back 7

A bus is a system of communication paths used to connect computer components and transfer data between them.

A parallel bus transmits data across multiple wires while a serial bus transmits across a single wire

Front 8

True or False?

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.

Back 8

True

Front 9

What are the characteristic features of conventional PCI?

Back 9

Maximum throughput of up to 533 MB/s

64-bit bus width

32-bit bus width

Parallel interface

Front 10

The Peripheral Component Interconnect eXtended (PCI-X) is an advanced version of PCI which:

Back 10

Doubles the bandwidth of PCI

Provides much faster data transfer rates in comparison to PCI

Offers backward compatibility with PCI devices

Didn't get much of a market success due to the development and widespread adoption of the PCIe standard

Was intended for devices with higher bandwidth requirements such as servers and high-end workstations

Front 11

What are the characteristics of the PCI-X standard?

Back 11

64-bit bus width

Maximum throughput of up to 1064 MB/s

Parallel interface

Front 12

What is a standard that relies on serial communication?

Back 12

PCIe

Front 13

Motherboard slots that enable installation of dedicated graphics controllers include:

Back 13

PCIe

AGP

Front 14

Peripheral Component Interconnect Express (abbr. as PCIe) is a high-speed, serial expansion bus designed as a replacement for:

Back 14

PCI-X

PCI

AGP

Front 15

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:

Back 15

Lane

Front 16

True or False?

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.

Back 16

True

Front 17

Which of the values listed below refers to the speed of a single-lane (x1) PCIe v1.x link?

Back 17

250 MB/s

Front 18

A single-lane (x1) PCIe v2.x link offers maximum throughput of up to:

Back 18

500 MB/s

Front 19

Which of the following answers lists the speed of a single-lane (x1) PCIe v3.x link?

Back 19

985 MB/s

Front 20

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:

Back 20

miniPCI

Front 21

Which of the following slot types allows for adding primary storage modules to the motherboard?

Back 21

RAM

Front 22

What are the features of a motherboard's CPU socket?

Back 22

PGA

PGA2

LGA

ZIF

Front 23

Which of the following integrated circuit types defines the core functionality and capabilities of a motherboard?

Back 23

Chipset

Front 24

True or False

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.

Back 24

False

Front 25

True or False

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.

Back 25

False
