Free Practice Questions for CompTIA FC0-U71 Exam

The correct answer is A. Unnecessary. The key phrase is “already handled natively by the OS.” Since the operating system already provides Wi-Fi settings management, the extra software is redundant and not required. It is not necessarily malicious, because the question does not say it is harmful. It is not best described as open-source, because licensing is unrelated to whether the software should be removed. “Unwanted” could describe software the user does not want, but “unnecessary” is more precise because the reason for removal is that the OS already performs the same function.

Exact Extract/Reference: The Tech+ Study Guide lists “Removal of software” and specifically includes “Unwanted,” “Unnecessary,” and “Malicious” software under software/security best practices. The guide also states that removing an application can free disk space and memory, and that Tech+ objective 6.2 expects knowledge of removing unwanted, unnecessary, and malicious software.

Markup languages, such as HTML and XML, use tags (e.g., < p > , < title > , < body > ) to define the structure and presentation of data. They are not programming languages in the traditional sense, as they don ' t include logic or execution flow.

“Markup languages use tags to annotate and structure text. Common examples include HTML and XML.” — CompTIA ITF+ Software Concepts

Correct answer: A

Task management utilities like Task Manager in Windows are used to monitor and manage running applications and processes, including ending unresponsive ones.

“Task Manager is used to view and end processes or applications that are not responding.” — CompTIA ITF+

Correct answer: B

A char (character) represents a single letter, number, or symbol. It differs from a string, which is a sequence of characters.

“The char data type stores a single alphanumeric character or symbol.” — CompTIA ITF+ Programming Fundamentals

Correct answer: C

Interference or poor signal strength is a common issue in Wi-Fi networks, especially in distant or obstructed locations like basements.

“Physical obstructions and electronic interference can weaken wireless signals, leading to connectivity issues in areas like basements.” — CompTIA ITF+ Networking Fundamentals

Correct answer: A

The CompTIA Tech+ Study Guide identifies RJ45 as the standard Ethernet connector:

“An RJ45 connector is used to connect network cables to devices such as switches, routers, and computers. It’s the most common connector for Ethernet networking.”

RJ45 connectors terminate Cat 5, 5e, and 6 cables for network communication.

Verified Reference:

Chapter 2: Peripherals and Connectors — “Network Connectors: RJ45” (pp. 90–92).

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

Although the values look numeric, the sequence “1, 10, 2...” suggests they are being treated as strings (text values), especially if they are not sorted numerically. In programming, strings are sequences of characters—even if those characters are digits.

“String data type is used to store alphanumeric characters, including numeric characters represented as text rather than numbers.” — CompTIA ITF+ Data Concepts

Correct answer: D

A MAC (Media Access Control) address is a hardware address assigned to a network interface card. It follows a 48-bit hexadecimal format usually displayed as six pairs separated by colons or hyphens:

“MAC addresses typically appear as 00:50:09:2D:4D:94.”

192.68.10.24 is an IPv4 address, fe80:102d:cd62:5434:82ae is an IPv6 address, and 0x3476 is simply a hexadecimal number, not a MAC address.
