A console or command-line interface (CLI) allows users to input text-based commands that the computer can execute.
"The console (or command prompt or terminal) allows direct command input to control an operating system or application without using a graphical interface." - CompTIA ITF+ Guide
* Services are background processes.
* Attributes define properties of objects or elements.
* Processes are executing programs but are not used for inputting commands.

To extract specific information from a database, especially recently updated entries, a query is 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

When a system administrator needs to troubleshoot a user's laptop remotely, especially over a VPN, they would use remote assistance software. 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

USB-C supports bidirectional communication, which means it can both send and receive data, including video, audio, power, and data signals over the same cable. This is unlike traditional video cables such as VGA, DVI, or even DisplayPort, which primarily transmit data in one direction.
"USB-C is a reversible connector capable of transmitting power, data, video, and audio signals. It is also bidirectional, allowing two-way communication between devices." - CompTIA ITF+ Study Guide
* VGA, DVI, and even DisplayPort are primarily unidirectional video outputs.
* Only USB-C fully supports modern bidirectional multimedia communication.
