The pseudocode reads from a block of numbers listed in line 40. This collection of values is structured like anarray—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

When a system administrator needs to troubleshoot a user’s laptop remotely, especially over a VPN, they would useremote assistancesoftware. This allows full or partial control over the target system for diagnostic and support tasks.

“Remote assistance software enables support personnel to remotely access and control another computer to perform diagnostics or provide help, often used in IT support scenarios.” — CompTIA ITF+ Guide

Correct answer: D

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.

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

Other options explained:

A. Printer – Output device

D. CPU – Core processing unit, not an input device

E. Speaker – Output device

F. SSD – Storage device

Correct answers: B and C

Meaningful reportingrefers to the process of analyzing and summarizing data into actionable insights to support business decisions.

“Reports generated from data analytics provide meaningful insights to support strategic decision-making by company leadership.” — CompTIA ITF+

Correct answer: A

Task managementutilities like Task Manager in Windows are used to monitor and manage running applications and processes, including ending unresponsive ones.

“Task Manager is used to view and end processes or applications that are not responding.” — CompTIA ITF+

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

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.

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.

The question asks how the value 9 can be represented using only ones and zeros, which is the definition ofbinary. In binary, the decimal number 9 is represented as1001.

“Binary is a base-2 numeral system that represents numeric values using only two symbols: 0 and 1. Computers use binary to process and store all data.” — CompTIA ITF+ Study Guide

Correct answer: C
