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?
Creating a pool in an Azure Databricks workspace helps to significantly reduce the time it takes for clusters to start and scale up. Pools reduce cluster start and auto-scaling times by maintaining a set of idle, ready-to-use instances that can be reused for different tasks. This approach minimizes the waiting time for instance provisioning, leading to faster job execution while minimizing costs because it avoids the higher cost associated with the Premium pricing tier and does not require additional setup like global init scripts or cluster policies.
Correct.
B is the answer
