FC0-U71 Practice Exam Questions with Answers CompTIA Tech+ Certification Exam Certification

The CompTIA Tech+ Study Guide explains:

“Solid-state drives (SSDs) use flash memory, which is non-magnetic and non-volatile. They have no moving parts, unlike HDDs, which use magnetic platters.”

It further notes:

“Conventional hard drives have spinning platters and read/write heads, whereas SSDs use flash memory. SSDs are faster but generally more expensive than their HDD counterparts.”

Therefore, SSD (solid-state drive) meets all the listed requirements.

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

The pseudocode reads from a block of numbers listed in line 40. This collection of values is structured like an array—a group of data elements stored together.

“An array is a collection of similar data elements stored in a structured sequence, often referenced or processed in loops.” — CompTIA ITF+ Programming Concepts

Correct answer: B

An access point is a networking hardware device that allows wireless devices to connect to a wired network using Wi-Fi or related standards. It helps extend the range of a wireless network by creating additional coverage areas. This is directly outlined in CompTIA ITF+ documentation:

“A wireless access point (AP) is a device that allows wireless clients to connect to a wired network. It serves to extend or broaden the wireless coverage.”

In contrast:

A modem connects to the internet via an ISP.

A server provides network services, not range.

A host firewall protects a single device or network; it does not expand connectivity.

Thus, the most appropriate answer is D.

Browsers store previously loaded pages in their cache to improve performance. If outdated content is cached, clearing the cache forces the browser to load the latest version from the server.

“Clearing the browser cache removes stored versions of web pages and resolves display issues caused by outdated content.” — CompTIA ITF+

Correct answer: C

A LAN (Local Area Network) connects devices in a limited geographical area such as a building or office.

“A LAN is a network that connects computers within a small geographical area such as a home, school, or office building.” — CompTIA ITF+ Networking Fundamentals

Correct answer: C

To install and use a printer over a network, the printer must have an assigned IP address so that it can be located and communicated with by other devices on the same network.

“Network printers are assigned IP addresses so computers can locate and send print jobs to them over the network.” — CompTIA ITF+ Networking Guide

Correct answer: B

Data at rest refers to information stored on a device or disk, such as a hard drive. The encryption that protects it is typically file-level encryption (or full-disk encryption).

“File-level encryption applies encryption to individual files or directories on storage media and is used to protect data at rest.” — CompTIA ITF+ Study Guide

VPN and HTTPS protect data in transit.

Plaintext means data is unencrypted, and therefore is not protective.

Therefore, A is the correct answer.

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

Because the pay rate is fixed and does not change for all workers, it is best represented as a constant in code. Constants are variables whose values do not change during execution.

“Constants are used in programming to represent fixed values that do not change during the run of a program.” — CompTIA ITF+ Software Development Guide

Correct answer: C

A printer is an output device because it receives digital data from a computer and converts it into a printed physical format (such as paper).

“Output devices display or reproduce information from the computer. Examples include monitors, speakers, and printers.” — CompTIA ITF+ Fundamentals

Correct answer: B

Encryption protects files by converting them into unreadable formats unless the correct decryption key is provided. The CompTIA ITF+ FC0-U71 Official Study Guide explains:

"Encryption is the process of converting data into a secure format that cannot be read without a decryption key. Only users with the proper key can access the original data."

File permissions control user access based on OS-level rules, but encryption specifically ensures that only those with the key can read the file even if they access the file storage.

Hidden folders merely conceal files but don’t protect content. Compression reduces file size but doesn’t protect access.

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).

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

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

“The hexadecimal notational system, or base-16… In hex, the numbers 0 to 9 are used, just like in decimal. However, the letters A to F are used to represent decimal numbers 10 through 15.”

This directly confirms that hexadecimal uses digits 0–9 and letters A–F.

Verified Reference:

Chapter 6: Software Development Concepts — “Notational Systems” (pp. 357–359).

A password reuse policy 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

Recording user actions is an example of accounting, which helps track what users do on a system, especially for auditing purposes.

“Accounting refers to the recording and logging of system activities, including tracking user actions within applications or services.” — CompTIA ITF+

Correct answer: A

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

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.

Markup languages, such as HTML and XML, use tags (e.g.,
