1Z0-1127-25 Prompt Engineering Practice Question
A data scientist is using self-consistency decoding to improve the accuracy of a reasoning task. Which of the following best describes the process?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Generate multiple independent reasoning paths and aggregate the final answers by majority voting
Self-consistency generates multiple reasoning paths (e.g., with higher temperature) and selects the most consistent answer by majority vote, improving reliability.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Generate one chain-of-thought reasoning path and use it as the final answer
Why it's wrong here
That is standard chain-of-thought, not self-consistency.
- ✓
Generate multiple independent reasoning paths and aggregate the final answers by majority voting
Why this is correct
Correct: self-consistency uses multiple paths and voting.
- ✗
Use a single forward pass with a low temperature setting
Why it's wrong here
Self-consistency requires multiple passes, often with varied temperature.
- ✗
Branch into multiple reasoning trees and prune less promising branches
Why it's wrong here
That describes tree-of-thought, not self-consistency.
