What is the primary difference between the HNSW and IVF vector indexes in Oracle Database 23ai?

• A.HNSW is partition-based, whereas IVF uses neighbor graphs for indexing
• B.Both operate identically but differ in memory usage
• C.HNSW uses an in-memory neighbor graph for faster approximate searches, whereas IVF uses the buffer cache with partitions
• D.HNSW guarantees accuracy, whereas IVF sacrifices performance for accuracy

Which SQL function is used to create a vector embedding for a given text string in Oracle Database 23ai?

• A.CREATE_VECTOR_EMBEDDING
• B.VECTOR_EMBEDDING
• C.GENERATE_EMBEDDING

In the following Python code, what is the significance of prepending the source filename to each text chunk before storing it in the vector database?
bash
CollapseWrapCopy
docs = [{"text": filename + "|" + section, "path": filename} for filename, sections in faqs.items() for section in sections]
# Sample the resulting data
docs[:2]

• A.It preserves context and aids in the retrieval process by associating each vectorized chunk with its original source file
• B.It improves the accuracy of the LLM by providing additional training data
• C.It helps differentiate between chunks from different files but has no impact on vectorization
• D.It speeds up the vectorization process by providing a unique identifier for each chunk
