- A
Use a single response with high temperature
Why wrong: Self-consistency requires multiple responses, not one.
- B
Generate multiple independent responses using chain-of-thought prompting
Multiple paths are needed for consistency.
- C
Set temperature to a non-zero value to introduce variation
Non-zero temperature ensures diversity in reasoning paths.
- D
Aggregate the final answers across the responses, e.g., by majority vote
Aggregation selects the most common answer.
- E
Use a stop sequence after each reasoning step
Why wrong: Stop sequences are not required; self-consistency works on final answers.

1Z0-1127 Prompt Engineering Practice Question
This 1Z0-1127 practice question tests your understanding of prompt engineering. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A prompt engineer wants to use the self-consistency technique to improve answer reliability. Which THREE steps are part of implementing self-consistency?
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 responses using chain-of-thought prompting
Option B is correct because self-consistency relies on generating multiple diverse reasoning paths via chain-of-thought (CoT) prompting. This technique samples several independent responses, each following a step-by-step reasoning process, to capture different valid approaches to the same problem.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the misconception that self-consistency can be achieved with a single high-temperature response, but the technique explicitly requires multiple independent samples to enable aggregation.
Detailed technical explanation
How to think about this question
Self-consistency works by setting a non-zero temperature (e.g., 0.7) to introduce controlled randomness in token sampling, then running multiple CoT chains (e.g., 5–10) independently. The final answers are aggregated via majority voting or weighted averaging, which reduces variance and improves reliability on tasks like arithmetic or commonsense reasoning. This technique is particularly effective when the model's single-pass accuracy is moderate but multiple paths converge on the same answer.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 1Z0-1127 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
