- A
Set the temperature to 0.0
Why wrong: Temperature affects randomness, not output format.
- B
Use a model fine-tuned for JSON generation
Why wrong: Overkill; prompt engineering is sufficient.
- C
Include a system instruction to output JSON
Why wrong: Helpful but not as reliable as explicit structured output instructions in the prompt.
- D
Specify the desired JSON schema in the prompt and use few-shot examples
Explicit schema description plus few-shot examples reliably produce JSON output.

Generative AI Leader Applying Generative AI in Business Practice Question
This Generative AI Leader practice question tests your understanding of applying generative ai in business. 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 marketing agency uses generative AI to create social media posts. They need the output to be in a specific JSON format for downstream processing. Which prompt technique should they use?
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
✓
Specify the desired JSON schema in the prompt and use few-shot examples
Option D is correct because explicitly specifying the desired JSON schema in the prompt combined with few-shot examples provides the most reliable way to enforce structured output from a generative AI model. This technique leverages the model's pattern-matching ability by showing concrete input-output pairs, which is more effective than vague instructions or parameter adjustments alone for achieving exact JSON formatting.
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
Google often tests the misconception that a simple parameter change (like temperature) or a vague instruction is sufficient to enforce structured output, when in reality explicit schema definition with examples is required for reliable JSON generation.

Command / output trap
Temperature affects randomness, not output format.
Detailed technical explanation
How to think about this question
Under the hood, few-shot prompting works by conditioning the model's next-token predictions on the provided examples, effectively creating an in-context learning task that biases the output distribution toward the desired format. This technique is particularly important for JSON generation because the model must adhere to strict syntactic rules (e.g., proper commas, brackets, key-value pairs) and schema constraints—something that temperature adjustments or simple instructions cannot enforce. In real-world pipelines, downstream parsers will fail on any deviation, making schema specification with few-shot examples a critical reliability measure.
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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
