Abyteconsists of exactly8 bits. Bits (binary digits) are the smallest unit of data, and eight of them grouped together form one byte, which is used to represent characters and numbers in digital systems.

“A byte is made up of 8 bits and is the standard unit of data used to represent information such as characters in computing.” — CompTIA ITF+ Fundamentals

Correct answer: C

When the network is unavailable, portable storage like a flash drive (USB storage device) is suitable for transferring large files:

“Flash drives provide portable storage solutions capable of handling large data files.”

NAS (network-attached storage) requires a functioning network. RAM is volatile memory not used for file transfer, and cloud storage requires internet connectivity.

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

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 If outdated credentials are appearing,clearing the cacheensures that old stored data is removed and the page loads fresh content.

“Cached data can include stored form data, which may result in outdated information being auto-filled.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

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.

USB-Csupports bidirectional communication, which means it can both send and receive data, including video, audio, power, and data signals over the same cable. This is unlike traditional video cables such as VGA, DVI, or even DisplayPort, which primarily transmit data in one direction.

“USB-C is a reversible connector capable of transmitting power, data, video, and audio signals. It is also bidirectional, allowing two-way communication between devices.” — CompTIA ITF+ Study Guide

VGA,DVI, and evenDisplayPortare primarily unidirectional video outputs.

OnlyUSB-Cfully supports modern bidirectional multimedia communication.

An e-reader is designed specifically for reading digital books in a portable, lightweight format:

“E-readers are mobile devices optimized for reading electronic books, offering portability, long battery life, and digital storage of thousands of titles.”

Servers, external drives, and workstations are either not portable or not designed for reading books.

Privacyinvolves protecting personal or sensitive information from being disclosed without consent. Sharing individuals’ birthdays and home addresses—even if they are public figures—violates the privacy principle.

“Privacy ensures that personal data is collected, used, and shared responsibly and legally. Exposing personal information in public forums can breach this principle.” — CompTIA ITF+ Official Objectives

Correct answer: C

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.

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 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.

Pseudocode represents logic written in plain, human-readable language that resembles programming structure but isn’t actual code:

“Pseudocode allows programmers to design algorithms using readable statements before translating them into actual code.”

Branch and sequence refer to control flow structures, and object-oriented refers to a programming paradigm.

Input devices allow users to interact with the computer by sending data to it. The most common input devices for a desktop PC setup are:

Mouse– allows the user to point, click, and interact with the GUI.

Keyboard– used to enter text and commands.

“Input devices such as the keyboard and mouse are essential for entering data into a computer.” — CompTIA ITF+ Study Guide
