Satellite internettypically suffers from higherlatencydue 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

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

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

To extract specific information from a database, especially recently updated entries, aqueryis used. Queries filter and retrieve data based on conditions like dates, fields, or status.

“A query is a request for data or information from a database table or combination of tables.” — CompTIA ITF+ Data Management

Correct answer: B

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.

Ane-readeris specifically designed for reading digital books using e-ink displays, which are easy on the eyes and readable in bright sunlight. They are lightweight, power-efficient, and ideal for book reading.

“E-readers use electronic ink displays for reading digital books, providing long battery life and excellent visibility in various lighting conditions.” — CompTIA ITF+

Correct answer: B

Apassword reusepolicy 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

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.

Avariableis a named space in memory used to store data that can change during program execution.

“Variables are memory storage locations used to hold data that can change while a program runs.” — CompTIA ITF+ Programming Concepts

Correct answer: A

UESTION NO: 83 [IT Concepts and Terminology]

A systems administrator resolves a persistent issue with a laptop. Which of the following steps should the administrator take next?

A. Test the theory.

B. Document the findings.

C. Create an action plan.

D. Implement the action plan.

Answer:B

After resolving the issue, the final step in the CompTIA troubleshooting methodology is todocument the findings. This includes noting what was done, what caused the issue, and how it was resolved, so others can reference it in the future.

“After resolving and verifying the issue, document the findings, actions taken, and outcomes to complete the troubleshooting process.” — CompTIA ITF+ Troubleshooting Steps

Correct answer: B

The syntax shown uses tags like and

, which are characteristic of amarkup language, specifically HTML (HyperText Markup Language). Markup languages describe the structure and presentation of text.

“Markup languages, such as HTML and XML, are used to annotate text so that the computer can manipulate it. HTML is used to design the structure of web pages using tags like ,

,

, etc.” — CompTIA ITF+ Official Guide

Other options:

Query languages like SQL retrieve data.

Compiled languages require compilation into machine code (e.g., C++).

Scripting languages are used for automation but don’t use markup syntax.

Correct answer: A
