- A
Fine-tuning a few thousand examples is insufficient; millions are required for any meaningful adaptation.
Why wrong: With PEFT techniques like LoRA, a few thousand examples can be sufficient for domain adaptation.
- B
RAG requires the model to have a high context window size to accommodate retrieved code snippets.
Why wrong: While helpful, many models already handle several thousand tokens; it's not a critical blocker.
- C
RAG eliminates the need for any model updates when private libraries change, because it retrieves the latest documentation at inference time.
RAG retrieves from a vector store that can be updated without retraining the model.
- D
Security constraints may favour RAG because sensitive code is never part of the model's weights.
RAG keeps source code in a controlled vector store; fine-tuning embeds it in model weights, which may be harder to audit.
- E
Fine-tuning can encode company-specific coding conventions directly into the model, reducing the need for style instructions in prompts.
Fine-tuning adapts the model's behaviour, including style, which is harder to achieve with RAG alone.
AI0-001 Implementing AI Solutions Practice Question
This AI0-001 practice question tests your understanding of implementing ai solutions. 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 company is building a code generation assistant for internal developers. They want the assistant to generate code snippets consistent with the company's coding style and use private libraries. They have a few thousand examples of internal code. Which THREE considerations are critical when deciding between fine-tuning a base LLM and using RAG?
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
RAG eliminates the need for any model updates when private libraries change, because it retrieves the latest documentation at inference time.
Fine-tuning can embed coding style and internal library knowledge into model weights, but requires regular updates. RAG is easier to update but may miss stylistic nuances. The volume of examples (a few thousand) is moderate; fine-tuning may still be feasible. Security and latency/availability are relevant for deployment.
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
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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 AI0-001 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.
