CompTIA FC0-U71 - CompTIA Tech+ Certification Exam

The correct answer is C. Company files saved on a hard disk. Data storage refers to keeping data so it can be used later. A hard disk drive provides long-term, nonvolatile storage and keeps files even when the computer is powered off. RAM is temporary volatile memory, Task Manager shows running processes and system information, and hardware IDs recorded on boards are not the best example of user data storage.

Exact Extract/Reference: The CompTIA Tech+ Study Guide explains that storage devices provide “long-term, nonvolatile, or persistent storage options,” meaning they do not lose data when powered off. It also states that HDDs are used for “permanent storage and quick access” and hold user data and files the system needs.

The CompTIA Tech+ Study Guide (Exam FC0-U71, 3rd Edition, 2025) explains that software requiring activation often stops working after a trial period—typically 30 days—until a valid product key is entered:

“Activating software is a different story—you have to do it. Either you will need to enter the product key before the app will work the first time, or it might work for a few times for free then ask you to activate. Some products… include activation features that lock the installed copy… Usually you have 30 days to do so, or a certain number of uses, before it stops working.”

This clearly identifies a product key as the required input to activate or continue using the software.

Pop-up blockers prevent new windows or tabs from opening, which can block reports that open in pop-up windows:

“If a web page uses pop-up windows to present information, a pop-up blocker may prevent the new content from loading.”

Cache clearing, accessibility options, or private browsing don’t directly affect hyperlink behavior.

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

A VPN (Virtual Private Network) creates a secure, encrypted connection over the internet between the user and a remote network, enabling secure access from home or public networks.

“VPNs provide a secure tunnel for transmitting data over unsecured networks, such as the internet, by encrypting all traffic between the client and the network.” — CompTIA ITF+ Security Topics

Other options:

A. LAN – Local and not for remote use

B. FTP – Transfers files but lacks modern encryption

C. DNS – Resolves domain names, not for access

Correct answer: D

The correct answer is A. CPU. The CPU, or central processing unit, is the processor that controls and directs computer activities. The operating system provides instructions, and the CPU processes them. An HDD stores data, RAM temporarily stores active data and instructions, and a NIC provides network connectivity. Only the CPU executes instructions.

Exact Extract/Reference: The CompTIA Tech+ Study Guide states that the role of the CPU is “to control and direct all the activities of the computer” and that the terms “processor” and “CPU” are interchangeable. It also explains that the processor “just does what it’s instructed to do.”

The CompTIA Tech+ Study Guide explains:

“A compiled programming language is one that requires the use of a compiler to translate it into machine code. Creating and using a program using a compiled language consists of three steps:

Write the source code.

Use a compiler to translate the source code into machine code.

Execute the program file, which usually has an .exe extension.”

Compiled languages package programs into executable files.

In flowcharts, a diamond represents a decision point — a place where the program branches based on a yes/no or true/false condition.

“A diamond shape in a flowchart is used to depict a decision, indicating that the flow can take different paths based on a condition.” — CompTIA ITF+ Programming Concepts

Correct answer: B

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

Anti-malware software 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
