FC0-U71 CompTIA Tech+ Certification Exam Free Practice Exam Questions (2025 Updated)

The CompTIA Tech+ Study Guide lists input devices explicitly:

“Input devices include keyboards, mice, scanners, and web cameras—any device that allows the user to enter data into the computer.”

In contrast, printers and speakers are output devices, while a motherboard is an internal component.

Verified Reference:

Chapter 2: Peripherals and Connectors — “Input and Output Devices” (pp. 102–104).

If the student’s built-in camera isn't functioning, it is likely due to a missing or outdated device driver. Updating the camera driver allows the OS to properly interface with the hardware.

“Drivers are essential software that enables communication between the OS and hardware devices. A malfunctioning camera often points to a driver issue.” — CompTIA ITF+

Correct answer: B

Installing software typically requires elevated permissions that standard user accounts do not have. The CompTIA ITF+ FC0-U71 Official Study Guide explains:

“An administrator account provides full system access, including installing or removing software, changing system settings, and managing user accounts.”

The user account does not have these privileges by default.

Least privilege refers to granting only the minimum permissions necessary (which would not typically include software installation for regular users).

Single factor refers to authentication methods, not access levels.

Since the employee is denied installation due to insufficient privileges, administrator access is needed to complete the installation.

Presentation software (e.g., Microsoft PowerPoint, Google Slides) is specifically designed to display information to an audience in a visual and organized format, making it ideal for meetings.

“Presentation software is used to create slide-based content that can be projected or shared in meetings to communicate ideas visually and effectively.” — CompTIA ITF+ Study Guide

Correct answer: D

The CompTIA Tech+ Study Guide (Exam FC0-U71, 3rd Edition, 2025) defines the least privilege model as:

“One of the key foundations of an authorization system is the least privilege model. This states that users should be granted only the least amount of access required to perform their jobs, and no more. This principle applies to computers, files, databases, and all other available resources.”

This concept ensures that a student cannot access restricted folders such as a teacher’s network folder, because their role does not require that level of access.

Verified Reference:

Chapter 10: Security Concepts and Threats — “Authorization and the Least Privilege Model” (pp. 549–550).

NVMe (Non-Volatile Memory Express) drives are high-speed storage devices that commonly use the M.2 form factor. M.2 allows for compact design and direct connection to the motherboard.

“M.2 is a compact form factor used for high-speed NVMe and SATA SSDs, enabling faster storage access in modern systems.” — CompTIA ITF+ Hardware Overview

Correct answer: A

Pop-up blockers prevent new windows or tabs from opening, which can block reports that open in pop-up windows:

“If a web page uses pop-up windows to present information, a pop-up blocker may prevent the new content from loading.”

Cache clearing, accessibility options, or private browsing don’t directly affect hyperlink behavior.

When a system administrator needs to troubleshoot a user’s laptop remotely, especially over a VPN, they would use remote assistance software. This allows full or partial control over the target system for diagnostic and support tasks.

“Remote assistance software enables support personnel to remotely access and control another computer to perform diagnostics or provide help, often used in IT support scenarios.” — CompTIA ITF+ Guide

Correct answer: D

Wireless interference is often caused by environmental factors such as proximity to kitchens, which may contain microwaves and other electronic devices operating on the same 2.4 GHz frequency used by many Wi-Fi networks. The CompTIA ITF+ FC0-U71 Official Study Guide explains:

“Wireless signals are subject to interference from physical objects, walls, appliances, and other electronic devices operating on the same frequency.”

“Microwave ovens and cordless phones are common sources of interference for Wi-Fi networks.”

In this case, the user's proximity to the kitchen is causing interference, not access control or standards issues.

The CompTIA Tech+ Study Guide defines:

“Devices that use radio frequency (RF) transmit a very limited range, typically only a few inches or so. This technology is fairly common in mobile payment applications. Because of the short distances involved, a related term you’ll see is near-field communication (NFC).”

NFC allows devices such as smartphones to securely transmit payment data over short distances—precisely the method used in vending machine purchases.

Verified Reference:

Chapter 2: Peripherals and Connectors — “Wireless Connections: NFC” (p. 99).

Process management in an operating system is responsible for controlling the execution of applications, assigning CPU time, and prioritizing active processes to optimize performance.

“Process management allocates resources, prioritizes applications, and ensures multitasking is efficiently handled by the OS.” — CompTIA ITF+ Operating Systems Guide

Correct answer: B

Recording user actions is an example of accounting, which helps track what users do on a system, especially for auditing purposes.

“Accounting refers to the recording and logging of system activities, including tracking user actions within applications or services.” — CompTIA ITF+

Correct answer: A

A password reuse policy prevents users from using the same password across multiple platforms or reusing previously used passwords. This is a best practice to reduce the risk of credential stuffing attacks.

“Password reuse policies help ensure users do not reuse old or existing passwords across multiple platforms, reducing exposure from compromised accounts.” — CompTIA ITF+ Security Objectives

Correct answer: A

A simple static web page is best created using a markup language, such as HTML. Markup languages describe the structure and formatting of content on a web page.

“Markup languages like HTML are used to design and structure static web content. They do not contain logic or interactivity like scripting languages.” — CompTIA ITF+ Study Guide

Correct answer: D

The CompTIA Tech+ Study Guide explains:

“Solid-state drives (SSDs) use flash memory, which is non-magnetic and non-volatile. They have no moving parts, unlike HDDs, which use magnetic platters.”

It further notes:

“Conventional hard drives have spinning platters and read/write heads, whereas SSDs use flash memory. SSDs are faster but generally more expensive than their HDD counterparts.”

Therefore, SSD (solid-state drive) meets all the listed requirements.

Verified Reference:

Chapter 1: Core Hardware Components — “Exploring Storage and Expansion Devices” (pp. 35–60).

USB-C is commonly used for both charging and data transfer between modern computers and smartphones. It supports high-speed data transmission and is a standard port on most new smartphones.

“USB-C cables support power delivery and high-speed data transfer, and are commonly used to connect smartphones to computers.” — CompTIA ITF+ Guide

VGA is for video output.

Thunderbolt is high-speed, but typically used with Apple or specialized hardware.

NFC is a wireless protocol, not a cable.

Correct answer: A

The CompTIA Tech+ Study Guide explains:

“For a table in a database to be relational, it must have a primary key. In fact, its creation is mandatory when a table is created. A primary key is one or more fields whose data is used to identify a record uniquely.”

It further adds:

“Primary keys for tables are stored in an index, which enforces the uniqueness requirement.”

Hence, the unique identifier for records in a relational database is the primary key.

Verified Reference:

Chapter 7: Database Fundamentals — “Primary Key” (pp. 394–395).

The pseudocode reads from a block of numbers listed in line 40. This collection of values is structured like an array—a group of data elements stored together.

“An array is a collection of similar data elements stored in a structured sequence, often referenced or processed in loops.” — CompTIA ITF+ Programming Concepts

Correct answer: B

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
