Question 6

Which of the following kinds of UPS runs off a battery?
A) offline UPS
B) UPS utility
C) standby UPS
D) online UPS

Accepted Answer

Online UPS runs off a battery all the time and provides continuous power to the connected equipment, making it the best choice for critical applications where uninterrupted power supply is crucial. The other types of UPS (offline, standby, and UPS utility) only use the battery during power outages or fluctuations, and hence may not provide as reliable and consistent power supply as an online UPS.

Question 7

COGNITIVE ASSESSMENT Your desktop houses its system unit in a frame made of metal.What is the term for this frame?
A) CPU
B) tower
C) bundle
D) server

Accepted Answer

The term for the frame that houses the system unit of a desktop computer is typically referred to as the "tower." Therefore, the correct answer is choice B. The CPU (choice A) refers to the central processing unit, which is one component housed within the tower. A bundle (choice C) typically refers to a collection of software or hardware that is sold together as a package deal, so it is not the correct answer in this case. A server (choice D) is a type of computer that is used to manage resources and provide services to other computers or devices on a network, so it is not the correct answer in this case either.

Question 10

COGNITIVE ASSESSMENT You are looking for a computer to provide a central location for online game play.What kind of computer do you need?
A) minicomputer
B) mainframe
C) supercomputer
D) server

Accepted Answer

A server computer is the best choice for providing a central location for online game play. Servers are designed to handle multiple requests from clients and provide centralized data storage and processing capabilities. They are also scalable, making them suitable for both small and large game communities. Minicomputers, mainframes, and supercomputers are expensive and typically designed for more specialized and intensive computing tasks, making them overkill for online game play.

Question 11

Which of the following is a device that plugs in a USB port on the computer or mobile device and contains multiple USB ports?
A) USB matrix
B) USB receiver
C) USB hub
D) USB replicator

Accepted Answer

A USB hub is a device that plugs into a USB port on the computer or mobile device and contains multiple USB ports, allowing multiple USB devices to be connected and used at the same time. USB matrix, USB receiver, and USB replicator are not commonly used terms for such a device.

Question 12

COGNITIVE ASSESSMENT You need to restore a computer that has suffered a catastrophic failure.Which of the following are you most likely to use?
A) dedicated server
B) domain name server
C) backup server
D) FTP server

Accepted Answer

When restoring a computer that has suffered a catastrophic failure, the most likely tool to use is a backup server. This is because a backup server keeps copies of important data and files, allowing for easier and efficient restoration of information in case of system failure or loss. A dedicated server is a remote computer dedicated to handling specific tasks, a domain name server is a server that translates domain names into IP addresses, and an FTP server is used for file transfer. While these tools may be useful in certain situations, they are not the most appropriate option for restoring a computer after a catastrophic failure.

Question 13

COGNITIVE ASSESSMENT You are going to make a decision about a server purchase based on whether it is a rack server, a blade server, or a tower server.On which of the following are you basing your decision?
A) resolution
B) base index
C) aggregator
D) form factor

Accepted Answer

The decision about whether to purchase a rack server, a blade server, or a tower server is based on form factor, which refers to the physical size, shape, and design of the server. Each of these types of servers has a different form factor, with rack servers being designed to be mounted in a rack, blade servers being designed to be inserted into a blade enclosure, and tower servers being designed to stand upright on a desk or floor. Therefore, the best choice is D.

Question 14

How many peripheral devices can you connect with a USB port?
A) up to 32
B) up to 45
C) up to 57
D) up to 127

Accepted Answer

A single USB port can theoretically support up to 127 devices. However, in practical terms, the number of devices that can be connected may depend on factors such as the power supply of the computer and the bandwidth required by each device.

Question 15

Which of the following is NOT a likely complaint of someone who spends his or her workday using the computer?
A) lower back pain
B) emotional fatigue
C) high blood pressure
D) muscle fatigue

Accepted Answer

Although prolonged periods of sitting and stress can contribute to high blood pressure, it is not a common complaint specifically related to computer use. The other choices (lower back pain, emotional fatigue, and muscle fatigue) are all common issues that can result from extended computer use.

Question 17

COGNITIVE ASSESSMENT A computer salesman refers to the shape and size of your new computer by a specific term.What term does he use?
A) resolution
B) aggregator
C) form factor
D) base index

Accepted Answer

The term "form factor" refers to the physical shape and size of a computer or its components. The other options - resolution, aggregator, and base index - do not specifically refer to shape and size.

Accepted Answer

A mail server is specifically designed to store and deliver email messages, making it the most logical choice for a small business looking to set up email communication. Network servers, file servers, and home servers may offer some similar functionality, but they are not optimized for email delivery and storage.

Question 20

Which of the following protects against electrical power variations?
A) cloud computing
B) surge protector
C) server virtualization
D) electronic leveling

Accepted Answer

A surge protector protects against electrical power variations by regulating the voltage level and protecting connected devices from power surges and spikes. Cloud computing, server virtualization, and electronic leveling do not provide protection against electrical power variations.
