CompTIA FC0-U71 - CompTIA Tech+ Certification Exam

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

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

A flat file is a simple database format often stored as a plain text or CSV file. It is ideal for small data sets where speed and simplicity are required.

“Flat files are simple and fast for storing small amounts of data and are easy to process without requiring a full database management system.” — CompTIA ITF+ Data Concepts

Correct answer: A

This scenario describes a situation where a user has already successfully logged into the system (i.e., has been authenticated) but cannot access a particular network resource (the shared folder). This falls under the concept of authorization, which determines what actions or resources a user is permitted to access after authentication.

“Authorization is the process of granting or denying access to network resources once the user has been authenticated.” — CompTIA ITF+ Official Study Guide

Authentication verifies the identity of the user (e.g., username and password).

Authorization controls access rights (e.g., shared folders, files).

Accounting tracks user activity (e.g., audit logs).

Non-repudiation ensures actions or transactions cannot be denied later.

Therefore, the correct answer is B: Authorization.

A query is a request for information from a database. Structured Query Language (SQL) is commonly used to retrieve specific records or information from a data set.

“A query is used to extract and retrieve specific data from a database based on defined criteria.” — CompTIA ITF+ Data Concepts

Correct answer: D

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

The correct answer is C. Onboard NICs are built into the motherboard. An onboard NIC is integrated into the motherboard, while an expansion card NIC is a separate add-on card installed into an expansion slot. The question asks for the primary difference, not speed or cost. Onboard does not automatically mean faster or more expensive.

Exact Extract/Reference: The CompTIA Tech+ Study Guide states that Tech+ objective 2.2 expects knowledge of “wired and wireless cards as well as onboard (integrated into the motherboard) versus expansion cards.” It also explains that “most computers today have the NIC circuitry integrated into their motherboards.”

An e-reader is designed specifically for reading digital books in a portable, lightweight format:

“E-readers are mobile devices optimized for reading electronic books, offering portability, long battery life, and digital storage of thousands of titles.”

Servers, external drives, and workstations are either not portable or not designed for reading books.

Conferencing software (e.g., Zoom, Microsoft Teams, Webex) enables users to conduct meetings online using audio, video, and screen sharing.

“Conferencing software facilitates real-time communication and collaboration over the internet through audio and video.” — CompTIA ITF+ Applications and Software
