A user wants to install new local storage on a workstation with the following requirements:
Non-magnetic
Non-volatile
Non-optical
Which of the following meets these requirements?
RAM
SSD
NAS
HDD
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.

A user identifies the reason a computer is not working, repairs it, and prints a test page. Which of the following steps should the user take next?
Submit a support ticket
Test the theory
Implement the solution
Document the actions taken
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
Given the following pseudocode:
10 READ Q,W
20 PRINT Q,W
30 GOTO 10
40 DATA 10,20,30,40,50,60,70,80,90,100
Which of the following best defines the type of data being used?
Boolean
Array
Variable
Function
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
Which of the following devices extends the range of a network?
Modem
Server
Host firewall
Access point
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.
A user is unable to load the most recent version of a web page. The old page loads each time the screen is refreshed. Which of the following would the user most likely do to resolve the issue?
Synchronize the profile.
Disable browser extensions.
Clear the cache.
Enable the pop-up blocker.
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
Which of the following best describes a group of computers that are in close proximity to each other on the same network?
MAC
Peer-to-peer
LAN
Client/server
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
Which of the following must be configured to install a printer on a network?
Physical address
IP address
MAC address
Access point
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
Which of the following encryption types protects data at rest?
File-level
VPN
HTTPS
Plaintext
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.
A user needs to read documentation on a device while walking around outdoors in bright sunlight. Which of the following is the best type of device for this purpose?
Laptop
Tablet
E-reader
Smartphone
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
A user is writing code to calculate the amount of pay for each worker at a company. The pay rate is the same for all workers. The code will use the formula:
amount_of_pay = number_of_hours × pay_rate
Which of the following should be used in the code to represent pay_rate?
Object
Function
Constant
Array
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
Which of the following describes a printer?
Processing
Output
Storage
Input
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
Which of the following makes a file readable only by select users who possess a key?
Hidden folders
File permissions
Compression
Encryption
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.
A user deletes a suspicious email from an unknown address. Which of the following security best practices is being applied?
Anti-malware
Anti-phishing
Authentication
Firewall
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).
Which of the following internet services traditionally has the most challenges with latency?
DSL
Fiber
Satellite
Cable
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
Which of the following notational systems uses the numbers 0–9 and letters A–F?
Octal
Binary
Decimal
Hexadecimal
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 user logs in with the same credentials across multiple websites. Which of the following password policies would most likely prevent this practice?
Reuse
Complexity
Privacy
Length
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
A programmer designs an application to record user actions in a log file for proper tracking. Which of the following best describes the recording component of the application?
Accounting
Authentication
Authorization
Non-repudiation
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
A programmer wants to write code that will be more efficient when executed at runtime. Which of the following language types should the programmer use?
Markup
Compiled
Query
Scripting
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
A lab technician removes access from students who do not need to use a fileshare. Which of the following best describes this action?
Least privilege model
Non-repudiation
Multifactor authentication
Single sign-on
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
Which of the following is the equivalent of 8 bits?
GB
Kilobyte
Byte
MHz
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.
Verified Reference:
Chapter 1: Core Hardware Components — Table 1.2 “Bit and Byte Conversions” (p. 36).
