Question 550
What long-term control is MOST directly justified by this Databricks GenAI situation? A low-cost support search uses short chunks but the proposed model multiplies embedding dimensions by eight.
Explanation
Correct Answer
Correct. Embedding width affects index storage and computation, and larger dimensions do not automatically improve task relevance. In the given situation — A low-cost support search uses short chunks but the proposed model multiplies embedding dimensions by eight. — the targeted safeguard action is: Do not assume highest dimensionality is best; maintain index compatibility when changing dimension. It preserves an enduring engineering or governance boundary after the current issue is fixed.
Incorrect Answers
Not the strongest safeguard choice for this specific question. Revalidate model choice after volume or source-document shape changes materially. This action primarily relates to Model selection by quality latency and budget: Select the smallest suitable model that meets a task's accuracy and latency constraints under realistic workload, not marketing rank. However, the described case — A low-cost support search uses short chunks but the proposed model multiplies embedding dimensions by eight. — is testing Embedding dimensions latency and index storage. It does not directly establish the safeguard outcome or constraint that the question requires; it may still be useful in a different stage or incident.
Not the strongest safeguard choice for this specific question. Keep component roles explicit so updates to a generation model do not silently alter retrieval vectors. This action primarily relates to Specialized model versus general LLM: Embedding, reranking, extraction and generative models solve different stages and should be evaluated for their actual role. However, the described case — A low-cost support search uses short chunks but the proposed model multiplies embedding dimensions by eight. — is testing Embedding dimensions latency and index storage. It does not directly establish the safeguard outcome or constraint that the question requires; it may still be useful in a different stage or incident.
Not the strongest safeguard choice for this specific question. Version embeddings with source and model identifiers to prevent silently mixing incompatible representations. This action primarily relates to Embedding model swap and reindex compatibility: Changed embedding dimensions or model semantics typically require re-embedding and index consistency before comparing search quality. However, the described case — A low-cost support search uses short chunks but the proposed model multiplies embedding dimensions by eight. — is testing Embedding dimensions latency and index storage. It does not directly establish the safeguard outcome or constraint that the question requires; it may still be useful in a different stage or incident.
