9- CompTIA A+ 220-1201 Practice Test

USB 2.0 (a.k.a. Hi-Speed USB) specifies the maximum data transfer rate of:

480 Mbps

What is the maximum allowable cable length for USB 2.0?

5 Meters

Which of the following answers refer to the USB 3.0 standard?

Backward compatibility with earlier USB versions

5 Gbps data transfer rate

SuperSpeed USB

USB 3.1 improves over its predecessors by supporting a maximum data transfer rate of:

10 Gbps

What is the maximum theoretical data transfer rate supported by USB 3.2?

20 Gbps

What is the maximum practical cable length for a typical USB 3.x connection?

3 meters

Which of the answers listed below refers to an older type of serial cable used to connect modems, printers, mice, and other peripheral devices?

RS-232

Thunderbolt 1 uses two separate 10 Gbps data channels, providing a combined maximum throughput of 20 Gbps. However, a single task may use only one of these channels at a time, limiting the speed to 10 Gbps per task. Thunderbolt 2 bonds the two channels into one unified 20 Gbps connection, allowing one high-bandwidth task to utilize the full capacity, while Thunderbolt 3 further increases this overall throughput to 40 Gbps. (T/F)

True

What is the maximum allowable length for a Thunderbolt copper cable?

Up to 3 meters

The fiber-optic Thunderbolt interface allows for a maximum cable length of:

60 meters

Which of the following answers refer(s) to video connection standards?

DisplayPort

HDMI

VGA

Which of the interfaces listed below provide the capability for transmission of both video and audio data?

HDMI

DisplayPort

What are the characteristic features of the signal that can be carried through an HDMI cable?

Digital Signal

Video and Audio

Which of the following answers best describes the signal capabilities of DisplayPort?

Digital audio/video

Which of the DVI versions listed below does not provide support for digital signal transmission?

DVI-A

Which DVI type does not provide support for analog signal transmission?

DVI-D

DVI-I provides support for both digital and analog video signal transmission.(T/F)

True

Which of the answers listed below refer to the characteristic features of the signal that can be carried through a standard VGA cable?

Video

Analog

USB-C supports Alternate Mode (Alt Mode), which allows it to transmit video signals using protocols such as DisplayPort or HDMI. Through Alt Mode, USB-C can deliver video to external displays like monitors or TVs, offering the same functionality as dedicated video cables. To connect to most external displays, USB-C requires a compatible adapter or cable, such as USB-C to DisplayPort or USB-C to HDMI. (T/F)

True

What are the characteristic features of SATA revision 1.0 (SATA I)?

The SATA interface specification defines a power connector consisting of:

15 pins

SATA revision 2.0 (SATA II) specifies:

3 Gbps data transfer rate

Maximum cable length of 1 meter

A single SATA data cable can be used to connect a motherboard slot with:

Only 1 device

The characteristic features of SATA revision 3.0 (SATA III) include:

Maximum cable length of 1 meter

6 Gbps data transfer rate

The SATA interface specification defines a data cable connector consisting of:

7 pins
