The CompTIA Tech+ Study Guide explains:

“For a table in a database to be relational, it must have a primary key. In fact, its creation is mandatory when a table is created. A primary key is one or more fields whose data is used to identify a record uniquely.”

It further adds:

“Primary keys for tables are stored in an index, which enforces the uniqueness requirement.”

Hence, the unique identifier for records in a relational database is the primary key.

Privacy involves protecting personal or sensitive information from being disclosed without consent. Sharing individuals’ birthdays and home addresses—even if they are public figures—violates the privacy principle.

“Privacy ensures that personal data is collected, used, and shared responsibly and legally. Exposing personal information in public forums can breach this principle.” — CompTIA ITF+ Official Objectives

Correct answer: C

Satellite internet typically suffers from higher latency due 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

A loop is a programming construct that repeats a set of instructions while a condition is true. This is used to automate repetitive tasks in code.

“Loops are used in programming to execute the same block of code multiple times under specific conditions.” — CompTIA ITF+ Programming Concepts

Correct answer: A

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

“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 management utilities like Task Manager in Windows are used to monitor and manage running applications and processes, including ending unresponsive ones.

“Task Manager is used to view and end processes or applications that are not responding.” — CompTIA ITF+

Correct answer: B

The least privilege model is a principle of giving users the minimum level of access needed to perform their roles. Removing unnecessary access aligns with this principle.

“Least privilege limits users to only the resources necessary for their duties, reducing the risk of unauthorized access.” — CompTIA ITF+ Security Essentials

Correct answer: A

Interference or poor signal strength is a common issue in Wi-Fi networks, especially in distant or obstructed locations like basements.

“Physical obstructions and electronic interference can weaken wireless signals, leading to connectivity issues in areas like basements.” — CompTIA ITF+ Networking Fundamentals

Correct answer: A

The correct answer is C. Assembly. Assembly language is the lowest-level language listed and is closest to machine code. It allows developers to write instructions that are translated into executable machine code. Scripting languages automate or run interpreted tasks, markup languages structure content such as web pages, and query languages are used to interact with databases.

Exact Extract/Reference: The CompTIA Tech+ Study Guide states that “assembly language is the lowest level of code in which people can write” and that it “allows the developer to provide instructions directly to the hardware.” It also states that assembly is translated into executable machine code by an assembler.

The CompTIA Tech+ Study Guide (Exam FC0-U71, 3rd Edition, 2025) defines the least privilege model as:

“One of the key foundations of an authorization system is the least privilege model. This states that users should be granted only the least amount of access required to perform their jobs, and no more. This principle applies to computers, files, databases, and all other available resources.”

This concept ensures that a student cannot access restricted folders such as a teacher’s network folder, because their role does not require that level of access.
