A) 3 feet
B) 13 feet
C) 33 feet
D) 44 feet

Question 6

COGNITIVE ASSESSMENT You have purchased a surge protector and you are happy with it, in part because it has an appropriate Joule rating.What is that rating?
A) 30
B) 60
C) 300
D) 600

Accepted Answer

The Joule rating refers to the amount of energy the surge protector can handle before it fails. A higher Joule rating means the surge protector can handle more energy and is therefore better at protecting your devices from power surges. Option D has the highest Joule rating at 600, making it the best choice.

Question 7

COGNITIVE ASSESSMENT Your electric service has been failing with some frequency lately because of a lot of storms, and you are looking for more peace of mind when it comes to a reliable power source for your computer.Which of the following could help?
A) GPS
B) Wi-Fi
C) UPS
D) server virtualization

Accepted Answer

A UPS (Uninterruptible Power Supply) helps to provide backup power to electronic devices during power outages or failures, ensuring that they continue to function until power is restored. This would be the best choice to provide more peace of mind for a reliable power source for a computer during stormy weather. GPS, Wi-Fi, and server virtualization are not related to providing backup power for electronic devices.

Question 10

COGNITIVE ASSESSMENT A type of computer usually has only one user.Which of the following is most likely to be the type of computer?
A) personal computer
B) supercomputer
C) server
D) SSD

Accepted Answer

A personal computer is designed for individual use and typically has only one user, making it the most likely type of computer. Supercomputers are used for complex computing tasks and are not typically designated for individual users. Servers are designed to host and manage multiple users and data, so they would not typically have only one user. SSDs (solid-state drives) are data storage devices, not computers.

Question 11

COGNITIVE ASSESSMENT You are looking for a general-purpose port to connect two devices together.Which of the following is your best bet?
A) Thunderbolt
B) DVI
C) HDMI
D) Mini HDMI

Accepted Answer

Thunderbolt is a general-purpose port that can connect various devices together, including computers, displays, external hard drives, and more. It offers high-speed data transfer rates, video and audio output, and power delivery, making it a versatile and reliable choice for many applications. DVI and HDMI ports are primarily used for video output, while Mini HDMI is a smaller version of HDMI. Therefore, Thunderbolt is the best choice for a general-purpose port.

Question 12

COGNITIVE ASSESSMENT You keep hearing a colleague of yours use a term and you are unfamiliar with it.Ultimately, however, you realize that it is a synonym for the term port.What is it?
A) unit
B) jack
C) scope
D) probe

Accepted Answer

A jack is often used interchangeably with port in reference to computer hardware, such as a USB jack or Ethernet jack. Units, scopes, and probes are not typically used as synonyms for port.

Question 13

COGNITIVE ASSESSMENT When an instrument in the dashboard of your car informs you the air pressure in the right rear tire is low, what type of computer determines the air pressure is low?
A) embedded computer
B) server
C) online linked computer
D) analog computer

Accepted Answer

An embedded computer is a type of computer that is built into other devices, such as cars, and is programmed to perform specific functions. In this case, the instrument in the dashboard of the car is likely using an embedded computer to determine the air pressure in the tire and display a warning if it is low. A server, online linked computer, or analog computer would not be appropriate for this task.

Question 14

COGNITIVE ASSESSMENT Last night, you experienced a power increase that lasted for less than one thousandth of a second.What is the term for this?
A) hit
B) joule
C) spike
D) juice

Accepted Answer

The term for a sudden, brief surge of power is commonly referred to as a "spike". Choices A, B, and D are not accurate terms for describing this situation.

Question 15

COGNITIVE ASSESSMENT You have just designed a device-tracking app for sale in the app marketplace.Which of the following are you least likely to use in your app?
A) GPS
B) Wi-Fi
C) UNIX
D) IP addresses

Accepted Answer

Unix is an operating system, not a technology used for tracking devices. The other options (GPS, Wi-Fi, and IP addresses) are commonly used for device tracking.

Question 16

COGNITIVE ASSESSMENT You want to connect your mobile device to a speaker.Which of the following is a way to do so?
A) with digital integration
B) via a port
C) using VoIP
D) via social media

Accepted Answer

Connecting a mobile device to a speaker can be done via a port, such as a headphone jack or Bluetooth connection. Digital integration, VoIP, and social media do not apply in this context.

Question 17

COGNITIVE ASSESSMENT Which of the following may need to happen before your Bluetooth headset can communicate with your smartphone?
A) They might need to be coupled.
B) They might need to be adapted.
C) They might need to be synced.
D) They might need to be paired.

Accepted Answer

The term "paired" is commonly used in Bluetooth technology to describe the initial connection between devices. This process is sometimes called "pairing" or "bonding," and it involves establishing a secure encrypted link between the two devices. Once paired, the devices can communicate with each other without the need for re-pairing unless they are disconnected or unpaired intentionally.

Question 18

COGNITIVE ASSESSMENT Your Bluetooth headset is waiting for another Bluetooth device to locate its signal.What is this mode known as?
A) intelligent mode
B) discoverable mode
C) listening mode
D) passkey mode

Accepted Answer

The mode where a Bluetooth device is waiting for another device to locate its signal is known as "discoverable mode." This allows other devices to find and connect to the Bluetooth device. The other options, "intelligent mode," "listening mode," and "passkey mode," do not accurately describe this mode.

Question 19

COGNITIVE ASSESSMENT Your new home has a vacuum system.What kind of computer is controlling it?
A) virtual computer
B) embedded computer
C) appliance computer
D) integrated computer

Accepted Answer

An embedded computer is designed to perform specific tasks and is often found in household appliances such as vacuum systems. It is different from a virtual computer, which is a software-based computer and is not controlling the vacuum system. An appliance computer and an integrated computer are not specific enough terms to determine whether they would be controlling a vacuum system.

Question 20

COGNITIVE ASSESSMENT What is the technology featured in the trend known as the Internet of Things?
A) embedded computers
B) Flash drives
C) SSDs
D) virtual computing

Accepted Answer

The technology featured in the trend known as the Internet of Things is embedded computers, which are small specialized computer systems that are integrated into everyday objects allowing them to connect to the internet and gather, analyze, and transmit data. Flash drives, SSDs, and virtual computing are not specifically associated with the Internet of Things.
