CompTIA Project+ (PK0-005) — Question 6

Which of the following describes three-tier architecture?

Answer options

• A. Conceptual, design, and implementation stages
• B. Presentation, application, and data processing
• C. Network, software, and security
• D. Development, testing, and production environment

Correct answer: B

Explanation

The correct answer is B, as three-tier architecture is specifically defined by its separation into presentation, application, and data processing layers. The other options refer to different concepts such as project phases (A), network components (C), and software lifecycle stages (D), which do not accurately represent three-tier architecture.
