The Databricks CLI allows users to manage clusters using command-line commands. The correct command for creating a cluster follows a specific format.

Key Components in the Command:

Command Type: databricks compute create is the correct syntax for creating a new compute resource (cluster).

Runtime Version: '14.3.x-scala2.12' specifies the Databricks runtime to use.

Workers: --num-workers 5 sets the number of worker nodes to 5.

Node Type: --node-type-id i3.xlarge defines the hardware configuration.

Cluster Name: --cluster-name DataEngineer_cluster assigns a recognizable name to the cluster.

Evaluation of Options:

Option A (databricks clusters create ...)

Incorrect: databricks clusters create is not a valid command in the Databricks CLI v0.205.

The correct CLI command for cluster creation is databricks compute create.

Option B (databricks clusters add ...)

Incorrect: databricks clusters add is not a valid CLI command.

Option C (databricks compute add ...)

Incorrect: databricks compute add is not a valid CLI command.

Option D (databricks compute create ...)

Correct: databricks compute create is the correct command for creating a cluster.

Conclusion:

The correct command to create a cluster with five workers, an i3.xlarge node type, and Databricks runtime 14.3.x-scala2.12 is:

databricks compute create 14.3.x-scala2.12 --num-workers 5 --node-type-id i3.xlarge --cluster-name Data Engineer_cluster

Thus, the correct answer is D.
