Data at restrefers to information stored on a device or disk, such as a hard drive. The encryption that protects it is typicallyfile-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

VPNandHTTPSprotect data in transit.

Plaintextmeans data is unencrypted, and therefore is not protective.

Therefore, A is the correct answer.

If the student’s built-in camera isn't functioning, it is likely due to a missing or outdateddevice driver. Updating the camera driver allows the OS to properly interface with the hardware.

“Drivers are essential software that enables communication between the OS and hardware devices. A malfunctioning camera often points to a driver issue.” — CompTIA ITF+

Correct answer: B

Pop-up blockers prevent new windows or tabs from opening, which can block reports that open in pop-up windows:

“If a web page uses pop-up windows to present information, a pop-up blocker may prevent the new content from loading.”

Cache clearing, accessibility options, or private browsing don’t directly affect hyperlink behavior.

AVPN (Virtual Private Network)creates a secure, encrypted connection over the internet between the user and a remote network, enabling secure access from home or public networks.

“VPNs provide a secure tunnel for transmitting data over unsecured networks, such as the internet, by encrypting all traffic between the client and the network.” — CompTIA ITF+ Security Topics

Other options:

A. LAN – Local and not for remote use

B. FTP – Transfers files but lacks modern encryption

C. DNS – Resolves domain names, not for access

Correct answer: D

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.

Cloud storageenables multiple users to access and modify data in real-time from different locations. It also ensureshigh availabilityby offering redundancy and online access.

“Cloud storage provides high availability, accessibility, and collaboration capabilities, making it ideal for group projects and remote access.” — CompTIA ITF+ Cloud Technologies

“Password expiration is a security policy that requires users to reset their passwords periodically—commonly 30, 60, or 90 days—to mitigate the risk of compromised credentials.” — CompTIA ITF+ Objectives

Password privacyrefers to keeping the password confidential.

Password historyrestricts reuse of old passwords.

Password complexityenforces character rules (e.g., uppercase, numbers, symbols).

Correct answer: D

Conferencing software(e.g., Zoom, Microsoft Teams, Webex) enables users to conduct meetings online using audio, video, and screen sharing.

“Conferencing software facilitates real-time communication and collaboration over the internet through audio and video.” — CompTIA ITF+ Applications and Software

Correct answer: D

Afirewallcan block traffic between workstations if it's not properly configured. If a user cannot connect from one device to another on the network, it is likely that the firewall settings are preventing this communication.

“Firewalls control the incoming and outgoing network traffic based on predetermined security rules. If improperly configured, they may block legitimate access between devices.” — CompTIA ITF+ Study Guide

Other options:

B. Database – Not related to connectivity

C. Anti-malware – Protects from malicious software, not network configuration

D. Certificate – Used for secure communication, but not basic connectivity

Correct answer: A

Line 10 starts with “FOR Q=1 TO 100,” which is aloop construct. It defines a loop that will run 100 times, incrementing Q from 1 to 100 and executing the enclosed lines (20 and 30).

“Loops are programming constructs that repeat a set of instructions until a condition is met. A ‘FOR’ loop is a common control structure in procedural programming.” — CompTIA ITF+ Official Objectives

Other options:

Attribute applies to objects, not control flow.

Sequence is the overall flow of code lines.

Branches involve decision-making (e.g., IF/ELSE), not repetition.

Correct answer: D

To install and use a printer over a network, the printer must have an assignedIP addressso 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

NVMe (Non-Volatile Memory Express)drives are high-speed storage devices that commonly use theM.2 form factor. M.2 allows for compact design and direct connection to the motherboard.

“M.2 is a compact form factor used for high-speed NVMe and SATA SSDs, enabling faster storage access in modern systems.” — CompTIA ITF+ Hardware Overview

That makes a total of4 recordsin the database schema.

Ahypervisoris the software or hardware platform that enables virtualization. It allows multiple operating systems (guest OSes) to run on a single physical machine.

“A hypervisor manages virtual machines on a single physical system. It enables the creation and management of guest OS environments.” — CompTIA ITF+

Correct answer: D

For locations without cable or cellular towers,satellite internetis the most viable solution. Satellite does not require terrestrial infrastructure beyond a dish and has global coverage.

“Satellite is often used in remote or rural locations where wired and cellular connectivity is not available. It uses a dish to communicate with orbiting satellites for internet access.” — CompTIA ITF+ Curriculum

Fiber optic and IDSL require ground cabling.

Cellular requires nearby towers, which the scenario rules out.

Correct answer: D. Satellite

When a new vulnerability is discovered in software, thebest way to secure itis byapplying updates (patches)released by the software vendor. According to the CompTIA ITF+ objectives:

“Vendors regularly release software updates and security patches to fix vulnerabilities that could be exploited by attackers. Installing these patches promptly is crucial for maintaining system security.”

Although configuring a firewall and authentication improves overall security, they do not directly patch or fix the vulnerability. Uninstalling may be an option only if a patch is unavailable or the software is no longer needed. Therefore, the best and most proactive response is B: Apply updates.

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.

Anembedded operating systemis used in dedicated devices such as smart appliances, printers, or industrial machines. It performs specific functions and interacts with other systems, like sending alerts.

“Embedded operating systems are designed to run on specialized hardware with a fixed function, such as in appliances or vehicles.” — CompTIA ITF+ Official Guide

Correct answer: B

Although a phone number contains only digits, it is best stored as astringbecause:

It doesn’t require mathematical operations.

It may include formatting symbols like dashes or parentheses.

“Phone numbers are stored as strings because they are identifiers, not values for computation.” — CompTIA ITF+ Data Types

Correct answer: A

Clicking thelock iconnext to a website’s URL allows users to view the security certificate, verify its issuer, expiration date, and encryption level—validating that the site is using HTTPS and is trusted.

“Browsers display a lock symbol for secure (HTTPS) websites. Clicking it reveals the SSL/TLS certificate details to verify the site’s authenticity.” — CompTIA ITF+ Security Essentials

The correct order of storage units from smallest to largest is:

Kilobyte (KB)

Megabyte (MB)

Terabyte (TB)

Petabyte (PB)

“A kilobyte is approximately 1,000 bytes. It is smaller than a megabyte (1 million bytes), terabyte (1 trillion bytes), or petabyte (1 quadrillion bytes).” — CompTIA ITF+ Reference

Hence, C. Kilobyte is the smallest unit listed.

Application datarefers to user-generated or application-specific files that are critical to retain. This includes saved work, preferences, and databases. These must be included in backups to ensure continuity and recovery.

“Application data and user-generated content should be prioritized in backups to ensure critical information is retained during restoration.” — CompTIA ITF+ Data Protection

Correct answer: B

Browsers store previously loaded pages in theircacheto 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

Interferenceor poor signal strength is a common issue in Wi-Fi networks, especially in distant or obstructed locations like basements.

“Physical obstructions and electronic interference can weaken wireless signals, leading to connectivity issues in areas like basements.” — CompTIA ITF+ Networking Fundamentals

Correct answer: A

A touch screen functions as both an input and output device. According to the CompTIA ITF+ FC0-U71 Official Study Guide:

"A touchscreen display is a hybrid device combining input and output. It shows visual output like a standard monitor but also allows the user to interact directly by touching the screen."

"Input devices allow users to provide data or control signals (e.g., keyboard, mouse, touchscreen)."

"Output devices show results from the computer's processing (e.g., monitor, printer, touchscreen)."

Touchscreens display information (output) and receive user input through touch (input). They do not perform storage, networking, processing, or logging.

Encryptionprotects data by encoding it, so it can only be accessed or read by someone with the proper key or password. It ensures confidentiality during file transfers over insecure networks like the internet.

“Encryption is used to protect data in transit, ensuring that only authorized parties can read the content during transmission.” — CompTIA ITF+ Security Essentials

Correct answer: C

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.

The CompTIA troubleshooting methodology is clearly outlined:

"Once a theory of probable cause has been established, the next step is to test that theory."

Testing confirms whether the identified potential cause is correct before proceeding with action planning, repairs, or documentation.

In object-oriented programming, methods are functions or procedures associated with an object that perform actions such as retrieving data:

“Methods are actions that an object can perform. They typically manipulate or retrieve data stored within the object.”

Variables store data, attributes define properties, and loops control repetition but do not directly handle data retrieval within objects.

Aflat fileis a simple database format often stored as a plain text or CSV file. It is ideal for small data sets where speed and simplicity are required.

“Flat files are simple and fast for storing small amounts of data and are easy to process without requiring a full database management system.” — CompTIA ITF+ Data Concepts

Correct answer: A

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