1. A product team wants to add AI search to their app within a few days for a demo. They have standard PDF and Markdown documents. Which approach best matches the lesson's recommendation?

   1. Use a hosted RAG platform to ship quickly
   2. Train a fine-tuned model on all documents
   3. Build a custom pipeline with bespoke chunking
   4. Implement semantic search from scratch without RAG

2. What specific aspects of retrieval does a team give up control over when they adopt a hosted RAG solution?

   1. The vector database infrastructure
   2. User authentication and API rate limits
   3. Only the embedding model weights
   4. Chunking, retrieval algorithms, and reranking strategies

3. A company processes invoices with highly non-standard layouts, handwritten notes in margins, and mixed multi-language content. Based on the lesson, what approach should they take?

   1. Build a custom RAG pipeline to handle unusual layouts
   2. Use any hosted RAG since they all handle weird formats
   3. Outsource to a translation service first
   4. Use a hosted RAG with additional prompt engineering

4. A team needs to launch an AI-powered support system for their documentation in under a week to meet a trade show deadline. Why is hosted RAG the recommended approach?

   1. It allows shipping a working RAG endpoint in days rather than months
   2. It automatically optimizes chunking for their specific documents
   3. It removes the need for any technical setup
   4. It provides better answer quality than custom pipelines

5. A company discovers their hosted RAG platform is consistently underperforming on technical documentation compared to a competitor's custom-built system. What is the most likely reason based on the lesson?

   1. Hosted RAG cannot match a tuned bespoke pipeline on retrieval quality
   2. The platform requires more training data
   3. The vector database is experiencing downtime
   4. Their API keys have insufficient permissions

6. What does the lesson suggest about migrating away from a hosted RAG platform?

   1. It is impossible once data is uploaded
   2. A full migration takes approximately three months
   3. Re-indexing elsewhere should be achievable in a weekend
   4. Migration requires rewriting all embeddings from scratch

7. A startup considers hosted RAG but is concerned about sensitive customer data. Based on the lesson, what concern should they have?

   1. Hosted RAG cannot hide their data from the vendor
   2. The vendor automatically deletes data after 90 days
   3. Data privacy laws do not apply to hosted RAG
   4. Hosted RAG provides complete data encryption

8. When is it appropriate to consider building a custom RAG pipeline instead of using a hosted service?

   1. When the team wants to avoid writing any code
   2. When the budget is extremely limited
   3. When the documents are standard PDFs and Word files
   4. When retrieval quality is the core product differentiator

9. A hosted RAG platform provides a 'reasonable answer schema.' What does this mean in practice?

   1. The schema can only handle simple questions
   2. The platform returns answers in a consistent, predictable format
   3. The platform requires schema configuration upfront
   4. The platform generates answers that are mediocre in quality

10. What is a key advantage of outsourcing chunking decisions to a hosted RAG platform?

    1. Chunking is handled faster by external APIs
    2. It automatically produces smaller chunks for better retrieval
    3. Outsourced chunking improves answer accuracy
    4. The team doesn't need to make complex document processing decisions

11. A team has moderate quality requirements for their internal knowledge base and needs to launch quickly. Based on the lesson, which option best fits?

    1. Use a general-purpose search engine instead
    2. Build custom RAG since internal tools need high quality
    3. Use hosted RAG since quality bar is moderate and time matters
    4. Train a base model on their documents

12. What happens to retrieval performance when a company uses a hosted RAG platform for documents with unconventional structures?

    1. Performance suffers because hosted platforms struggle with unusual layouts
    2. Performance increases but answer quality decreases
    3. Performance improves automatically due to the vendor's optimization
    4. Performance stays the same regardless of document format

13. What is the primary risk of becoming dependent on a hosted RAG platform for a critical product feature?

    1. The platform will shut down within a year
    2. The vendor will use the data to compete with them
    3. The team may not be able to easily adapt retrieval to changing needs
    4. The platform will eventually increase prices significantly

14. A team decides to build their own RAG pipeline despite the additional complexity. What is the most likely business justification?

    1. The team wants to avoid learning about AI technologies
    2. Their documents are simple enough that hosted RAG would be overkill
    3. Building from scratch is always cheaper than hosted solutions
    4. Retrieval quality directly determines whether customers will pay for the product

15. Based on the lesson, what should a company do before committing to a hosted RAG platform for sensitive documents?

    1. Upload documents immediately to test answer quality
    2. Disable all API logging to protect privacy
    3. Sign a lifetime contract to get the best rates
    4. Ensure they maintain copies of original documents in their own storage
