Aconsoleor 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.

Correct answer: D

USB-Cis commonly used for both charging and data transfer between modern computers and smartphones. It supports high-speed data transmission and is a standard port on most new smartphones.

“USB-C cables support power delivery and high-speed data transfer, and are commonly used to connect smartphones to computers.” — CompTIA ITF+ Guide

VGA is for video output.

Thunderbolt is high-speed, but typically used with Apple or specialized hardware.

NFC is a wireless protocol, not a cable.

Correct answer: A

ALAN (Local Area Network)connects devices in a limited geographical area such as a building or office.

“A LAN is a network that connects computers within a small geographical area such as a home, school, or office building.” — CompTIA ITF+ Networking Fundamentals

Correct answer: C

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.

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.

Installing software typically requires elevated permissions that standard user accounts do not have. The CompTIA ITF+ FC0-U71 Official Study Guide explains:

“An administrator account provides full system access, including installing or removing software, changing system settings, and managing user accounts.”

The user account does not have these privileges by default.

Least privilege refers to granting only the minimum permissions necessary (which would not typically include software installation for regular users).

Single factor refers to authentication methods, not access levels.

Since the employee is denied installation due to insufficient privileges,administrator accessis needed to complete the installation.

CPU speed is measured inmegahertz (MHz)orgigahertz (GHz), indicating how many million or billion cycles the processor can execute per second.

“CPU performance is commonly measured in megahertz (MHz) or gigahertz (GHz), representing the processor’s clock speed.” — CompTIA ITF+

MB is for memory/storage size.

Mbps is for network speed.

MAC is a hardware address, not a performance metric.

Correct answer: A

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.

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

A relational database uses tables consisting of rows and columns where a primary key uniquely identifies each row (record). As stated in the CompTIA ITF+ FC0-U71 Official Study Guide:

"Relational databases store data in tables consisting of rows and columns. Each table has a primary key, which uniquely identifies each record."

"Document and key/value databases are types of NoSQL databases and do not use primary keys in the same structured tabular format."

Non-structured databases (like object storage or big data repositories) do not enforce primary keys.
