- A
Use Retrieval-Augmented Generation (RAG) with the policy documents indexed in a vector store
RAG retrieves relevant document chunks at query time, ensuring the chatbot always answers from the latest uploaded documents without any model retraining.
- B
Train a custom model from scratch on the policy documents each month
Why wrong: Training from scratch requires massive compute resources and weeks of time — entirely disproportionate for monthly document updates.
- C
Use a larger foundation model with a longer context window and paste all documents into each prompt
Why wrong: Pasting all documents into every prompt is expensive, hits context limits for large document sets, and does not scale as the document library grows.
- D
Fine-tune a base LLM on the policy documents monthly
Why wrong: Fine-tuning is expensive and time-consuming; monthly cycles are impractical and fine-tuned knowledge becomes stale immediately after cutoff.
AI0-001 AI Concepts and Techniques Practice Question
This AI0-001 practice question tests your understanding of ai concepts and techniques. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 wants to build a customer service chatbot that answers questions about their internal policy documents. The documents are updated monthly, and the team cannot afford to retrain a model each time. Which approach is MOST appropriate?
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
Use Retrieval-Augmented Generation (RAG) with the policy documents indexed in a vector store
Retrieval-Augmented Generation (RAG) is the most appropriate approach because it allows the chatbot to answer questions by retrieving relevant chunks from the policy documents stored in a vector store, without requiring model retraining when documents are updated monthly. The retrieval component dynamically fetches the latest content, while the generation component uses a pre-trained LLM to produce answers, making it cost-effective and scalable for frequently changing knowledge bases.
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
Cisco often tests the misconception that fine-tuning or training from scratch is the only way to adapt a model to new data, ignoring the efficiency of retrieval-based approaches like RAG for dynamic knowledge bases.
Detailed technical explanation
How to think about this question
RAG works by embedding policy documents into a vector store using models like text-embedding-ada-002, then at query time performing approximate nearest neighbor (ANN) search (e.g., using FAISS or HNSW) to retrieve the top-k relevant chunks. The retrieved chunks are concatenated with the user query into a prompt for the LLM, enabling grounded generation without modifying model weights. A subtle behavior is that chunk size and overlap must be tuned to balance retrieval precision and context relevance; too large chunks may include irrelevant information, while too small chunks may miss context.
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 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.
