FC0-U71 CompTIA Tech+ Certification Exam Free Practice Exam Questions (2026 Updated)

The correct answer is D. Variable. In the pseudocode, Q receives input from the user and then prints that input. Since the value of Q can change each time the program loops back to line 10, Q is a variable. It is not a constant because constants do not change. It is not a function because it is not a reusable block of code. It is not an array because it does not represent a list of values.

Exact Extract/Reference: The CompTIA Tech+ Study Guide explains that a “constant” is a predefined number that does not change, while “a variable” means the value can change. It also states that variables can change throughout a program based on input.

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

The CompTIA Tech+ Study Guide (Exam FC0-U71, 3rd Edition, 2025) defines phishing as:

“Creating a site or sending an email that masquerades as a legitimate secure site but actually steals your information is called phishing.”

It further explains:

“When people talk about phishing, it’s generally in the context of suspicious email because that’s how the term originated. Hackers sent out messages hoping to get someone to take the bait.”

By deleting a suspicious email without opening or clicking links, the user is practicing anti-phishing awareness — a key cybersecurity best practice.

Verified Reference:

Chapter 11: Security Best Practices — “Recognizing Suspicious Sites, Links, and Ads” and “Phishing” (pp. 587–589).

After identifying the issue, implementing a solution, and verifying functionality (test page), the next step in the troubleshooting process is to document the solution for future reference.

“The final step in the troubleshooting methodology is to document findings, actions, and outcomes to ensure organizational learning and continuity.” — CompTIA ITF+ Study Guide

Correct answer: D

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

A GPU (Graphics Processing Unit) is a specialized processor designed to perform calculations related to rendering images and videos. It’s an example of a processing component.

“The GPU is a processor dedicated to graphical computations and image rendering, assisting or replacing the CPU in handling visual data.” — CompTIA ITF+ Hardware Essentials

Correct answer: C

The CompTIA Tech+ Study Guide details this advantage:

“If you need to have multiple concurrent users accessing data, you need a database. Flat files don’t do well when several people try to access them at once. In the vast majority of cases, one user might be able to write to the file, but all users will be limited to a read-only copy.”

It further states:

“Databases generally lock only on a record level… so multiple people can actively use the database at one time.”

Therefore, the primary advantage of databases over flat files is support for multiple concurrent users.

Verified Reference:

Chapter 7: Database Fundamentals — “When to Use Databases” (pp. 389–391).

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

“A crimper is used to attach modular connectors, such as RJ45 or RJ11, to network or phone cables. The crimper pushes the metal contacts into the wires, securing them in place.”

Punchdown tools, by contrast, are used for patch panels or keystone jacks, not RJ45 ends.

Chapter 2: Peripherals and Connectors — “Networking Tools: Crimpers, Punchdown Tools, Cable Testers” (pp. 106–108).

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

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

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

A relational database uses tables consisting of rows and columns where a primary key uniquely identifies each row (record). As stated in the CompTIA ITF+ FC0-U71 Official Study Guide:

" Relational databases store data in tables consisting of rows and columns. Each table has a primary key, which uniquely identifies each record. "

" Document and key/value databases are types of NoSQL databases and do not use primary keys in the same structured tabular format. "

Non-structured databases (like object storage or big data repositories) do not enforce primary keys.

Disk management is the OS feature used to create, delete, format, or partition storage devices. It allows users to manage drives and volumes locally.

“Disk management tools are used to manage and configure storage devices, including creating and formatting partitions and volumes.” — CompTIA ITF+ Operating System Features

Correct answer: D

If a USB port is disabled in the BIOS or device manager, the system won’t detect devices connected to it. This is the most likely cause if nothing happens when a USB device is inserted.

“Hardware ports can be disabled via firmware settings or device policies, which prevents detection of peripherals.” — CompTIA ITF+ Hardware Troubleshooting

Correct answer: A

The correct answer is B. Firewall. A firewall filters network traffic based on configured rules. To disallow inbound file-sharing connections, the firewall can block the relevant inbound traffic. Anti-malware scans for malicious software, multifactor authentication verifies identity, and certificates help establish trust or encryption, but a firewall is the correct control for blocking inbound network connections.

Exact Extract/Reference: The CompTIA Tech+ Study Guide states that firewalls “filter inbound and outbound network traffic based on rules defined by the administrator.” It also explains that host-based firewalls protect one computer and that Windows includes Microsoft Defender Firewall. The guide further explains that firewall ACLs determine which traffic is passed and which traffic is blocked.

Web browsers store cached data to improve loading speeds and remember form inputs. If outdated credentials are appearing, clearing the cache ensures that old stored data is removed and the page loads fresh content.

“Cached data can include stored form data, which may result in outdated information being auto-filled. Clearing the browser cache resolves this.” — CompTIA ITF+ Official Curriculum

Correct answer: C

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.

Verified Reference:

Chapter 8: Networking Concepts and Technologies — “Router” section (pp. 446–447).

A keyboard allows a user to enter data into a system:

“Input devices allow users to provide data or control signals to the computer; keyboards are primary examples.”

Storage saves data, output displays data, and processing handles data operations.

The CompTIA Tech+ Study Guide states:

“Floats are numbers that include decimals. Integers are whole numbers with no decimals, and strings are text.”

An example from the book:

“It’s a float data type, which is a number with a decimal place.”

Therefore, -2.34 represents a float.
