1Z0-1127-25 Fundamentals of Large Language Models Practice Question
A research team is experimenting with few-shot prompting to improve a model's performance on a complex reasoning task. They find that the model's performance degrades when the few-shot examples are too similar to each other. What is the likely cause and best remedy?
⚠ Common exam trap
Oracle often tests the misconception that more examples always improve performance, when in fact diversity is critical to prevent overfitting in few-shot prompting.

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
✓
The examples lack diversity, causing the model to overfit to a narrow pattern. Use more diverse examples.
When few-shot examples are too similar, the model overfits to a narrow pattern, reducing its ability to generalize to the diverse reasoning paths required by the task. This is a known limitation of in-context learning: the model treats the examples as a template rather than as diverse demonstrations. Using more diverse examples exposes the model to a wider range of reasoning patterns, improving robustness.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The model has not seen enough examples. Increase the number of few-shot examples.
Why it's wrong here
More similar examples may not help; diversity is key.
- ✗
The examples are presented in a confusing order. Reorder them by difficulty.
Why it's wrong here
Order is less impactful than diversity.
- ✓
The examples lack diversity, causing the model to overfit to a narrow pattern. Use more diverse examples.
Why this is correct
Diverse examples reduce bias and improve generalization.
- ✗
The temperature is too low, making the model too deterministic. Increase temperature slightly.
Why it's wrong here
Temperature does not address example similarity.
