Question 600
Developers generate stored vectors with one model but query vectors with an incompatible unrelated model. Which result would provide the strongest acceptance evidence?
Explanation
Correct Answer
Vector distance is meaningful only when source and query representations share compatible model geometry. The observation “An aligned held-out query retrieves known matching passages after embeddings are regenerated” directly confirms the chosen action worked for this situation: Developers generate stored vectors with one model but query vectors with an incompatible unrelated model.
Incorrect Answers
Higher-dimensional embeddings are not automatically more accurate for a specific domain. This observation would not establish that the required result occurred for Developers generate stored vectors with one model but query vectors with an incompatible unrelated model. The confirming test is: An aligned held-out query retrieves known matching passages after embeddings are regenerated.
Equal vector dimensions do not guarantee semantic comparability across model revisions. This observation would not establish that the required result occurred for Developers generate stored vectors with one model but query vectors with an incompatible unrelated model. The confirming test is: An aligned held-out query retrieves known matching passages after embeddings are regenerated.
ANN tuning requires a measured quality-performance tradeoff, not just benchmark QPS. This observation would not establish that the required result occurred for Developers generate stored vectors with one model but query vectors with an incompatible unrelated model. The confirming test is: An aligned held-out query retrieves known matching passages after embeddings are regenerated.
