CompTIA CompTIA Tech+ Certification Exam FC0-U71 Exam Dumps: Updated Questions & Answers (August 2026)

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.

Changing the router ' s password (particularly the Wi-Fi password) prevents unauthorized users from reconnecting to the network. It’s the most immediate and effective response.

“One of the most effective ways to secure a wireless network is by changing the default and existing passwords to prevent unauthorized access.” — CompTIA ITF+ Security Topics

Calling support may help but doesn’t address the issue directly.

Decreasing signal range may reduce but not eliminate access.

Resetting the router is more disruptive and unnecessary if the password can be changed.

Correct answer: C

A console or command-line interface (CLI) allows users to input text-based commands that the computer can execute.

“The console (or command prompt or terminal) allows direct command input to control an operating system or application without using a graphical interface.” — CompTIA ITF+ Guide

Services are background processes.

Attributes define properties of objects or elements.

Processes are executing programs but are not used for inputting commands.

Correct answer: D

In terms of storage measurement hierarchy:

1TB = 1,000GB

1GB = 1,000MB

1MB = 1,000KB

Therefore:

20TB = 20,000GB

2,000GB = 2,000GB

200MB = 0.2GB

2,000KB = 0.002GB

Thus, 20TB is the largest. The CompTIA ITF+ FC0-U71 Official Study Guide defines storage units in this way under data representation topics.

To extract specific information from a database, especially recently updated entries, a query is used. Queries filter and retrieve data based on conditions like dates, fields, or status.

“A query is a request for data or information from a database table or combination of tables.” — CompTIA ITF+ Data Management

Correct answer: B

A variable is a named space in memory used to store data that can change during program execution.

“Variables are memory storage locations used to hold data that can change while a program runs.” — CompTIA ITF+ Programming Concepts

Correct answer: A

UESTION NO: 83 [IT Concepts and Terminology]

A systems administrator resolves a persistent issue with a laptop. Which of the following steps should the administrator take next?

A. Test the theory.

B. Document the findings.

C. Create an action plan.

D. Implement the action plan.

Answer: B

After resolving the issue, the final step in the CompTIA troubleshooting methodology is to document the findings. This includes noting what was done, what caused the issue, and how it was resolved, so others can reference it in the future.

“After resolving and verifying the issue, document the findings, actions taken, and outcomes to complete the troubleshooting process.” — CompTIA ITF+ Troubleshooting Steps

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.

According to the CompTIA Tech+ Study Guide (Exam FC0-U71, 3rd Edition, 2025):

“A router is a highly intelligent network connectivity device that can connect multiple network types to each other. Routers use routing tables to store network addresses and route packets based on the best path available.”

It further clarifies:

“Wireless routers are common in homes and offices. Functionally, wireless routers work just like their wired cousins.”

The default gateway in a home network is the router, as it serves as the device that connects the internal local area network (LAN) to the external Internet.

The least privilege model is a principle of giving users the minimum level of access needed to perform their roles. Removing unnecessary access aligns with this principle.

“Least privilege limits users to only the resources necessary for their duties, reducing the risk of unauthorized access.” — CompTIA ITF+ Security Essentials

Correct answer: A

The CompTIA Tech+ Study Guide provides a conversion table for storage units:

“1 bit = 1 bit, a single 0 or 1.

8 bits = 1 byte (one text character).

1,000 bytes = 1 kilobyte (KB).”

Thus, 8 bits equals 1 byte.
