Databricks Certified Data Engineer Professional — Question 215

A data engineer wants to create a cluster using the Databricks CLI for a big ETL pipeline. The cluster should have five workers and one driver of type i3.xlarge and should use the '14.3.x-scala2.12' runtime.

Which command should the data engineer use?

Answer options

• A. databricks compute add 14.3.x-scala2.12 --num-workers 5 --node-type-id i3.xlarge --cluster-name Data Engineer_cluster
• B. databricks clusters create 14.3.x-scala2.12 --num-workers 5 --node-type-id i3.xlarge --cluster-name Data Engineer_cluster
• C. databricks compute create 14.3.x-scala2.12 --num-workers 5 --node-type-id i3.xlarge --cluster-name Data Engineer_cluster
• D. databricks clusters add 14.3.x-scala2.12 --num-workers 5 --node-type-id i3.xlarge --cluster-name Data Engineer_cluster

Correct answer: B

Explanation

The correct command is B because 'databricks clusters create' is the proper command for initiating a new cluster with the specified configuration. Option A and C incorrectly use 'compute' instead of 'clusters', while option D suggests adding to an existing cluster, which is not applicable here since a new cluster needs to be created.
