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 that wireless performance and range are significantly affected by interference:

“Interference from other electronics and obstructions will lower the data rate. Radio frequency interference (RFI) from communications devices will degrade the signal. Microwave ovens and electrical motors are notoriously harsh on wireless signals. Solid objects, especially concrete block walls and steel, cut down on range as well.”

Hence, interference is the most likely cause for the reduced wireless coverage.

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

Compiled languages (e.g., C, C++, Go) are translated into machine code before execution, making them faster and more efficient at runtime than interpreted or scripting languages.

“Compiled code is translated into machine language before execution, providing faster performance compared to interpreted code.” — CompTIA ITF+ Software Concepts

Correct answer: B

To visually represent steps in a process (such as a flowchart or workflow), diagramming software is the most appropriate tool. These applications are designed for creating flowcharts, organizational charts, and other process diagrams.

“Diagramming software is used to create visual representations of workflows, processes, and systems. Common uses include flowcharts and process maps.” — CompTIA ITF+ Study Guide

Correct answer: D

The correct order for creating a network cable:

Measure and cut with wire cutter

Strip the wires

Attach Ethernet connector using a crimper

Finally, test the cable with a cable tester to ensure connectivity and proper pinout.

“After crimping the RJ-45 connectors, a cable tester is used to validate the electrical continuity and correct wiring order.” — CompTIA ITF+ Curriculum

Correct answer: A

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.

Satellite internet typically suffers from higher latency due to the long distances signals must travel to orbit and back. Even with high download speeds, the time delay in communication is significant.

“Satellite internet often experiences high latency due to the long signal travel time between Earth and orbiting satellites.” — CompTIA ITF+ Networking Concepts

Correct answer: C

According to the CompTIA Tech+ Study Guide (Exam FC0-U71, 3rd Edition, 2025), the SFP (Small Form-Factor Pluggable) connector is directly associated with fiber-optic networking. The guide lists:

“SFP (small form-factor pluggable) connectors are commonly used in fiber-optic connections to allow hot-swappable transceivers for different types of fiber cables.”

Additionally, the same guide’s chapter on Networking Concepts and Technologies explains:

“Fiber-optic around 2 Gbps – Incredibly fast and more expensive than DSL or cable.”

Therefore, fiber Internet is the only service type that uses SFP connectors for data transmission over optical cables.

An open-source license allows users to access, modify, and redistribute the software’s source code. It supports user customization and community contributions.

“Open-source software provides access to the source code, allowing users to inspect, modify, and enhance the software.” — CompTIA ITF+ Licensing and Software Concepts

Correct answer: C
