Free CompTIA FC0-U71 Practice Exam with Questions & Answers

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.

Account logsprovide details about authentication attempts and can confirm whether a user successfully logged in or was denied access.

“Authentication events are recorded in system and application logs, helping verify login success or failure.” — CompTIA ITF+ Security Concepts

Correct answer: A

Theweb browser historystores records of websites that a user has visited. This is typically the most straightforward and accessible method for determining whether users accessedinappropriate or unauthorized online content. The CompTIA ITF+ documentation explains:

“Web browsers maintain a history of visited URLs, which can be used for monitoring and auditing user activity, including detecting policy violations regarding internet usage.”

System logsare broader and generally capture system or security events.

Cookiesstore session and tracking data but don’t always show what content was accessed.

Location trackinghelps with geolocation, not content monitoring.

Therefore, the correct choice is D.

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

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.

E-readers(especially those using e-ink displays) are specifically designed for reading in bright environments. E-ink mimics the appearance of ink on paper, offering excellent visibility in sunlight with minimal glare and very low power consumption.

“E-readers use e-ink technology which makes the screen easily readable in bright environments like sunlight. This makes them ideal for reading documentation outdoors.” — CompTIA ITF+ Guide

Laptops, tablets, and smartphones may suffer from glare or screen dimming in direct sunlight.

Correct answer: C

Tablets typically connect to wireless networks using Wi-Fi, which adheres to the IEEE 802.11 standard (often seen as 802.11a/b/g/n/ac/ax). The correct protocol family for this type of connection is802.11X(referring to Wi-Fi technologies broadly).

“Wireless devices such as tablets use the 802.11 standards to connect to Wi-Fi access points for network connectivity.” — CompTIA ITF+

Other options:

B. Thunderbolt and D. USB-C – Wired connection standards

C. Bluetooth – Short-range peripheral communication, not Wi-Fi

Correct answer: A

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

Apassword reusepolicy 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

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
