Flashcard Practice Databricks Certified Machine Learning Associate Multiple Choice

During a production outage, a shared Databricks cluster is saturated by a tuning job. The grid has 6 maxDepth values and 5 regParam values, CrossValidator uses 10 folds, and parallelism is 5. A developer expected only 5 models because of the parallelism setting. What is the accurate diagnosis?

Choose the Best Answer

The job has 5 candidate fits because parallelism replaces the parameter grid. The job has 30 candidate fits because the grid size is used once before folding. The job still has 300 candidate fits; parallelism limits concurrent work rather than total work. The job has 50 candidate fits because folds are multiplied by parallelism.
