CCAO-F Claude Model Fundamentals Practice Question
A customer support team is building a Claude-powered assistant that must answer questions using a 300-page product manual. They want to avoid sending the entire manual with every request because of latency and cost. Which approach best leverages Claude's capabilities while keeping responses grounded in the manual?
⚠ Common exam trap
The trap here is assuming that fine-tuning or a lower temperature can teach Claude a private 300-page manual, when grounding actually requires retrieving and injecting the relevant passages at request time.

Correct answer & explanation
✓
Use retrieval-augmented generation: embed the manual, retrieve the most relevant passages, and include them in the prompt.
Retrieval-augmented generation is the standard architecture for grounding Claude in a large, private, frequently updated document such as a product manual. Embedding the manual and retrieving only the most relevant passages keeps prompts small, reduces latency and cost, and gives Claude authoritative source text to answer from. Fine-tuning, max_tokens, and temperature do not supply the missing manual content and therefore cannot ensure grounded support answers.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Use retrieval-augmented generation: embed the manual, retrieve the most relevant passages, and include them in the prompt.
Why this is correct
RAG keeps the authoritative manual outside the model and injects only the top matching passages into the context window. This reduces token usage and latency, allows the manual to be updated without retraining, and gives Claude the exact source text to cite. It is the recommended pattern for grounding answers in a large, evolving document set such as a 300-page product manual.
- ✗
Lower the temperature to 0 so Claude reproduces the manual verbatim from memory.
Why it's wrong here
Temperature affects randomness in sampling, not factual memory. Setting it to 0 makes outputs more deterministic but cannot cause Claude to recall a private manual it never saw in training. The team would still lack grounding, and deterministic hallucinations are no better than varied ones. Temperature tuning is not a substitute for retrieval or context injection.
- ✗
Increase the max_tokens parameter so Claude can generate longer, more detailed answers directly from its training data.
Why it's wrong here
max_tokens controls response length, not access to the manual. Raising it does not give Claude the product manual content and may increase cost and latency. Claude's pretraining does not include this private manual, so longer outputs would still be ungrounded and prone to hallucination. The parameter is unrelated to the retrieval problem described.
- ✗
Fine-tune Claude on the manual so the knowledge is embedded in the model weights.
Why it's wrong here
Fine-tuning on 300 pages of proprietary content is expensive, slow to iterate, and does not reliably teach factual recall; it mainly shapes style and format. It also makes updates cumbersome because each manual revision requires a new training run, and it risks overfitting. Retrieval, not weight modification, is the standard way to ground Claude in a large, changing knowledge base for support assistants.
