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

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.

To visually represent steps in a process (such as a flowchart or workflow),diagramming softwareis the most appropriate tool. These applications are designed for creating flowcharts, organizational charts, and other process diagrams.

“Diagramming software is used to create visual representations of workflows, processes, and systems. Common uses include flowcharts and process maps.” — CompTIA ITF+ Study Guide

Correct answer: D

Accountingrefers to the logging and monitoring of user actions. In this case, tracking login events through log files is an example of accounting in the AAA (Authentication, Authorization, Accounting) model.

“Accounting provides auditing and logging of user actions, such as login times and resource access.” — CompTIA ITF+ Security Essentials

Correct answer: A

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.

Gaming monitors are often described using refresh rates, which are measured in hertz (Hz), often specified in MHz for related processing frequencies. The CompTIA ITF+ FC0-U71 Official Study Guide states:

"Monitor refresh rate refers to how many times per second the screen updates, usually measured in Hz."

"MHz (megahertz) is used for various frequencies, including GPU and monitor refresh processing."

GPU and RAM refer to hardware components, TB measures storage, and MHz relates to the frequency, applicable for monitor performance metrics.

Achar (character)represents a single letter, number, or symbol. It differs from a string, which is a sequence of characters.

“The char data type stores a single alphanumeric character or symbol.” — CompTIA ITF+ Programming Fundamentals

Correct answer: C

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

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.

Aprinteris anoutputdevice 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
