Free Practice Questions for CompTIA FC0-U71 Exam

The correct answer is A. To present identical content on multiple displays. Display mirroring is used when the same screen image must appear on more than one display, such as a laptop screen and a projector in a conference room. This is useful for presentations because the audience sees the same content the presenter sees. Mirroring does not improve cloud speed, add security by itself, or share files from network-attached storage.

Exact Extract/Reference: The Tech+ Study Guide explains that when “two or more displays are used at the same time to project the same image, that is called mirroring.” It also states that “all actions performed on one display” are shown on the mirrored display.

In the database schema shown in the images, there are four rows (excluding the header row) representing data entries for four people (John, Jane, Allison, and Anna).

Each row represents a record in the database table, also known as a tuple. The term record refers to a complete set of fields (ID, Name, and Age) for one entry. So, counting the four rows:

John

Jane

Allison

Anna

That makes a total of 4 records in the database schema.

In object-oriented programming, methods are functions or procedures associated with an object that perform actions such as retrieving data:

“Methods are actions that an object can perform. They typically manipulate or retrieve data stored within the object.”

Variables store data, attributes define properties, and loops control repetition but do not directly handle data retrieval within objects.

Input devices allow users to interact with the computer by sending data to it. The most common input devices for a desktop PC setup are:

Mouse – allows the user to point, click, and interact with the GUI.

Keyboard – used to enter text and commands.

“Input devices such as the keyboard and mouse are essential for entering data into a computer.” — CompTIA ITF+ Study Guide

Other options explained:

A. Printer – Output device

D. CPU – Core processing unit, not an input device

E. Speaker – Output device

F. SSD – Storage device

Correct answers: B and C

A variable is a named space in memory used to store data that can change during program execution.

“Variables are memory storage locations used to hold data that can change while a program runs.” — CompTIA ITF+ Programming Concepts

Correct answer: A

UESTION NO: 83 [IT Concepts and Terminology]

A systems administrator resolves a persistent issue with a laptop. Which of the following steps should the administrator take next?

A. Test the theory.

B. Document the findings.

C. Create an action plan.

D. Implement the action plan.

Answer: B

After resolving the issue, the final step in the CompTIA troubleshooting methodology is to document the findings. This includes noting what was done, what caused the issue, and how it was resolved, so others can reference it in the future.

“After resolving and verifying the issue, document the findings, actions taken, and outcomes to complete the troubleshooting process.” — CompTIA ITF+ Troubleshooting Steps

Correct answer: B

The correct answer is B. Hypervisor. A hypervisor is the software layer that enables virtualization. It allows multiple virtual machines or guest operating systems to share the same physical computer and controls how physical resources such as CPU, memory, storage, and networking are assigned to those virtual systems. A guest OS uses the resources assigned to it but does not manage the overall allocation. PaaS and SaaS are cloud service models, not the virtualization component that allocates virtual computer resources.

Exact Extract/Reference: The Tech+ Study Guide states that the hypervisor is “also known as a virtual machine manager (VMM)” and “manages the physical resource allocation” to virtual operating systems. The Exam Essentials also states that a hypervisor “allows multiple operating systems to share the same host” and manages physical resource allocation.

Anti-malware software is specifically designed to detect, quarantine, and remove malicious software from a system. It is the most appropriate tool for protecting a computer after a suspicious or infected file is downloaded.

“Anti-malware software scans downloaded files and running processes to identify and remove malicious software, providing real-time protection against viruses, trojans, and spyware.” — CompTIA ITF+ Study Guide

Other options:

B. Firewall – Prevents unauthorized access but doesn’t clean infections

C. Patching – Prevents exploitation of known vulnerabilities, not infection removal

D. Permissions – Limit access but do not remove malware

Correct answer: A

USB-C supports bidirectional communication, which means it can both send and receive data, including video, audio, power, and data signals over the same cable. This is unlike traditional video cables such as VGA, DVI, or even DisplayPort, which primarily transmit data in one direction.

“USB-C is a reversible connector capable of transmitting power, data, video, and audio signals. It is also bidirectional, allowing two-way communication between devices.” — CompTIA ITF+ Study Guide

VGA, DVI, and even DisplayPort are primarily unidirectional video outputs.

Only USB-C fully supports modern bidirectional multimedia communication.

Correct answer: D

The CompTIA Tech+ Study Guide details this advantage:

“If you need to have multiple concurrent users accessing data, you need a database. Flat files don’t do well when several people try to access them at once. In the vast majority of cases, one user might be able to write to the file, but all users will be limited to a read-only copy.”

It further states:

“Databases generally lock only on a record level… so multiple people can actively use the database at one time.”

Therefore, the primary advantage of databases over flat files is support for multiple concurrent users.

Chapter 7: Database Fundamentals — “When to Use Databases” (pp. 389–391).

The correct answer is A. Flowchart. A flowchart is used before coding to visually plan how a program flows from one step to the next. A linear sequence is a set of ordered logical steps, and a flowchart is designed to show that order clearly. Object-oriented programming is a programming model based on objects and classes, not a planning tool for a sequence. Branching is logic that chooses between paths, and Boolean is a true/false data type or result.

Exact Extract/Reference: The Tech+ Study Guide states that “A flowchart is a visual representation of a program that uses boxes to represent the logic” and that flowcharts help developers “visualize the flow of the program.” It also states that flowcharts show the “order of operations within a program.” The review answer confirms that “A flowchart is designed to depict visually the sequence of events and logic within a program.”
