CompTIA ITF+ (FC0-U61) — Question 278

A programmer is designing an expert system that uses a series of closed-ended questions to arrive at specific output. Which of the following characteristics will MOST likely be used in the code for the expert system to achieve this?

Answer options

• A. Branching
• B. Looping
• C. Arrays
• D. Vectors

Correct answer: A

Explanation

Branching is crucial in an expert system as it allows the program to follow different paths based on the user's responses to closed-ended questions. Looping, arrays, and vectors do not directly support the decision-making process required for navigating through a series of questions and responses.
