- A
Add a system instruction specifying 'Use the most recent API version and avoid deprecated functions.'
System instructions provide explicit guidance to the model on desired behavior.
- B
Set top-p to 0.5 to reduce output diversity
Why wrong: Top-p controls token selection probabilities, not temporal relevance.
- C
Provide one few-shot example of a correct API call
Why wrong: One example might not be enough; also instruction is more scalable.
- D
Set temperature to 1.5 to increase creativity
Why wrong: Higher temperature increases randomness, not correctness regarding API versions.

Generative AI Leader Practice Question: Techniques to Improve Generative AI Model Output
This Generative AI Leader practice question tests your understanding of techniques to improve generative ai model output. 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 developer is using the Gemini API to generate code snippets. They notice the outputs often contain deprecated API calls. Which parameter adjustment or prompt strategy would most effectively encourage the model to use current APIs?
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
✓
Add a system instruction specifying 'Use the most recent API version and avoid deprecated functions.'
Option A is correct because adding a system instruction that explicitly directs the model to 'Use the most recent API version and avoid deprecated functions' directly influences the model's behavior at the prompt level. The Gemini API supports system instructions that act as persistent, high-level guidance, steering the model toward preferred output patterns—in this case, avoiding deprecated API calls. This is the most effective and direct method to enforce current API usage without altering sampling parameters or relying on limited examples.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Common exam traps
Common exam trap: answer the scenario, not the keyword
This question tests the misconception that adjusting sampling parameters (like temperature or top-p) or providing a single example can reliably enforce content constraints, when in fact system instructions are the designed mechanism for persistent behavioral guidance in production-grade APIs.
Detailed technical explanation
How to think about this question
System instructions in the Gemini API are prepended to the conversation context and are weighted more heavily than user messages, effectively acting as a persistent behavioral constraint. This leverages the model's instruction-following capability, which is fine-tuned to prioritize explicit directives over implicit patterns from training data. In real-world scenarios, a developer maintaining a legacy codebase could use a system instruction like 'Always use the latest stable version of the Google Cloud Client Libraries' to ensure generated snippets avoid deprecated endpoints like the older `google-api-python-client` methods.
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.
