- A
Define the JSON schema in the system prompt
Defining the schema sets the expected structure.
- B
Provide a concrete example of the desired JSON output
Examples demonstrate the exact format expected.
- C
Use a stop sequence of "}"
Why wrong: Stop sequence on closing brace may truncate JSON before it is complete.
- D
Increase max tokens to 5000
Why wrong: Max tokens does not directly help with output format adherence.
- E
Set temperature to 1.0 for creativity
Why wrong: High temperature reduces reliability; legal tasks need lower temperature.

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 is designing a prompt for legal document analysis. The model should output JSON with a specific structure. Which TWO practices are essential to include in the prompt?
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
✓
Define the JSON schema in the system prompt
Option A is correct because defining the JSON schema in the system prompt explicitly instructs the model on the exact structure and data types required for the output. This is a foundational practice in prompt engineering for structured data generation, as it reduces ambiguity and ensures the model adheres to a predefined format, which is critical for downstream parsing in legal document analysis.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

- ✗
Use a stop sequence of "}"
Why it's wrong here
Stop sequence on closing brace may truncate JSON before it is complete.
- ✗
Increase max tokens to 5000
Why it's wrong here
Max tokens does not directly help with output format adherence.
- ✗
Set temperature to 1.0 for creativity
Why it's wrong here
High temperature reduces reliability; legal tasks need lower temperature.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse 'stop sequences' (used to truncate output) with 'format constraints' (like JSON schemas), or assume higher token limits and creative temperature settings are universally beneficial, when in fact they degrade reliability for structured data tasks.
Trap categories for this question
Command / output trap
Max tokens does not directly help with output format adherence.
Detailed technical explanation
How to think about this question
Under the hood, large language models like GPT-4 use token probability distributions to generate text; a temperature of 1.0 flattens these probabilities, increasing variability, which can break JSON syntax (e.g., mismatched brackets or invalid keys). In real-world legal document analysis, even a single malformed JSON field can cause automated compliance systems to fail, so combining a schema definition with a concrete example (few-shot prompting) anchors the model's output distribution toward the exact required structure, leveraging in-context learning to reduce hallucination of extraneous fields.
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.
