Question
You have an Azure Databricks workspace that contains an all-purpose cluster named Cluster1.
You need to configure Cluster1 to meet the following requirements:
- Scale up automatically when workloads increase
- Scale down automatically when workloads decrease
- Minimize costs
Which two actions should you perform? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.
- A. Disable Photon acceleration.
- B. Enable autoscaling for Cluster1. Correct
- C. Apply a compute policy that enables users to manage the cluster settings.
- D. Specify a fixed number of workers.
- E. Configure Cluster1 to terminate after 30 minutes of inactivity. Correct
Explanation
Autoscaling adds workers when demand rises and removes them when it falls, and it can reduce cost compared to a statically sized cluster. Automatic termination stops an all-purpose cluster after a period of inactivity, so you stop paying for it while it is idle. A fixed number of workers is the opposite of autoscaling. Disabling Photon has no effect on scaling, and a policy that lets users manage cluster settings neither scales the cluster nor limits its cost.
