Which statement describes a disadvantage of using a Command Line Interface?

• A. It is only typed in text
• B. It provides rich graphical feedback
• C. It automates all tasks without user input
• D. It processes audio signals

Answer: (A)

The idea being tested is that a Command Line Interface is text-based, which can be a drawback for many users. Because interaction relies on typing commands and reading text responses, there are no built-in icons, menus, or visual cues to guide you. This makes learning and discovering what you can do harder, increases the chance of typos causing errors, and can slow tasks that graphical interfaces would handle with simple clicks or drag-and-drop. While power users can be very efficient with a CLI, its text-only nature is the main downside for those who benefit from visual feedback. The other statements don’t describe typical CLI characteristics: CLI usually doesn’t provide rich graphical feedback, it doesn’t automate everything without input, and it isn’t designed to process audio signals by itself.
