Flashcard Practice Databricks Certified Machine Learning Professional Multiple Choice

During a production migration, a fraud team launches a 30-day transaction-count feature that must be fresh within minutes. If the stream starts from the current Kafka offset, many established accounts will initially have incomplete counts. What launch plan is most defensible?

Choose the Best Answer

Start the stream from the latest offset and let the feature become accurate after 30 days. Backfill historical counts, then continue streaming updates from a controlled checkpoint. Shorten the feature window to one day until enough streaming data accumulates. Use a model default for established accounts and skip historical feature computation.
