Databricks Certified Data Engineer Professional — Question 56

A distributed team of data analysts share computing resources on an interactive cluster with autoscaling configured. In order to better manage costs and query throughput, the workspace administrator is hoping to evaluate whether cluster upscaling is caused by many concurrent users or resource-intensive queries.

In which location can one review the timeline for cluster resizing events?

Answer options

• A. Workspace audit logs
• B. Driver's log file
• C. Ganglia
• D. Cluster Event Log
• E. Executor's log file

Correct answer: D

Explanation

The correct answer is D, as the Cluster Event Log specifically tracks all events related to the cluster's scaling activities. Options A, B, C, and E do not provide the necessary information about cluster resizing events, as they focus on different aspects of cluster operation and performance monitoring.
