Administering Relational Databases on Microsoft Azure — Question 18

You have an Azure Databricks workspace named workspace1 in the Standard pricing tier. Workspace1 contains an all-purpose cluster named cluster1.
You need to reduce the time it takes for cluster1 to start and scale up. The solution must minimize costs.
What should you do first?

Answer options

• A. Upgrade workspace1 to the Premium pricing tier.
• B. Configure a global init script for workspace1.
• C. Create a pool in workspace1.
• D. Create a cluster policy in workspace1.

Correct answer: C

Explanation

Creating a pool in workspace1 allows for faster provisioning of clusters by reusing existing resources, which helps in reducing startup and scaling times while minimizing costs. Upgrading to the Premium tier (Option A) incurs additional expenses without addressing the scaling issue directly. Configuring a global init script (Option B) does not impact the cluster's startup time and a cluster policy (Option D) focuses on governance rather than performance optimization.
