You are noticing job cluster is taking 6 to 8 mins to start which is delaying your job to finish on time, what steps you can take to reduce the amount of time cluster startup time
A . Setup a second job ahead of first job to start the cluster, so the cluster is ready with re-sources when the job starts
B . Use All purpose cluster instead to reduce cluster start up time
C . Reduce the size of the cluster, smaller the cluster size shorter it takes to start the cluster
D . Use cluster pools to reduce the startup time of the jobs
E . Use SQL endpoints to reduce the startup time

Answer: D

Explanation:

The answer is, Use cluster pools to reduce the startup time of the jobs.

Cluster pools allow us to reserve VM’s ahead of time, when a new job cluster is created VM are grabbed from the pool. Note: when the VM’s are waiting to be used by the cluster only cost incurred is Azure. Databricks run time cost is only billed once VM is allocated to a cluster.

Here is a demo of how to setup and follow some best practices, https://www.youtube.com/watch?v=FVtITxOabxg&ab_channel=DatabricksAcademy
