A MAC (Media Access Control) address is a hardware address assigned to a network interface card. It follows a 48-bit hexadecimal format usually displayed as six pairs separated by colons or hyphens:

“MAC addresses typically appear as 00:50:09:2D:4D:94.”

192.68.10.24 is an IPv4 address, fe80:102d:cd62:5434:82ae is an IPv6 address, and 0x3476 is simply a hexadecimal number, not a MAC address.

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.

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.

AGPU (Graphics Processing Unit)is a specialized processor designed to perform calculations related to rendering images and videos. It’s an example of aprocessingcomponent.

“The GPU is a processor dedicated to graphical computations and image rendering, assisting or replacing the CPU in handling visual data.” — CompTIA ITF+ Hardware Essentials

Correct answer: C

Task managementtools such as Task Manager in Windows or Activity Monitor in macOS allow users to monitor running applications and processes. They also provide the functionality to force-close (end) applications that are not responding.

“Task Manager provides a way to close applications that are unresponsive and manage running processes.” — CompTIA ITF+ Official Guide

Correct answer: A

The correct order for creating a network cable:

Measure and cut with wire cutter

Strip the wires

Attach Ethernet connector using a crimper

Finally, test the cable with acable testerto ensure connectivity and proper pinout.

“After crimping the RJ-45 connectors, a cable tester is used to validate the electrical continuity and correct wiring order.” — CompTIA ITF+ Curriculum

Correct answer: A

This structure usesbranching, which allows a program to make decisions based on conditions using "if," "else if," and similar statements.

“Branching allows the flow of execution in a program to change based on decisions or conditions.” — CompTIA ITF+ Programming Concepts

Correct answer: D

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

Correct answer: D

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

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
