Free Practice Questions for CompTIA FC0-U71 Exam

USB-Csupports 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 evenDisplayPortare primarily unidirectional video outputs.

OnlyUSB-Cfully supports modern bidirectional multimedia communication.

Correct answer: D

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

Anti-malwaresoftware 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-Cis 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

Task managementutilities 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

Aqueryis 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

Clicking thelock iconnext to a website’s URL allows users to view the security certificate, verify its issuer, expiration date, and encryption level—validating that the site is using HTTPS and is trusted.

“Browsers display a lock symbol for secure (HTTPS) websites. Clicking it reveals the SSL/TLS certificate details to verify the site’s authenticity.” — CompTIA ITF+ Security Essentials

Correct answer: A

Anembedded operating systemis used in dedicated devices such as smart appliances, printers, or industrial machines. It performs specific functions and interacts with other systems, like sending alerts.

“Embedded operating systems are designed to run on specialized hardware with a fixed function, such as in appliances or vehicles.” — CompTIA ITF+ Official Guide

Correct answer: B

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.
