I completely agree, because the exception will not be generated and the code inside this block (exception) will not be executed.

Agreed, the code given actually represents the compute creation, if there was no computeOne then the code will create one but as in this case there is already a computeOne, Exception block will not be executed

The answer is incorrect. No, yes, yes is correct because Compute 1 already exists

In the first line of the code : try : ....... print('Step1') We are checking if the compute already exists or not. Since it has been created the print will work, and so the "exception" sequence won't be executed. the fact that the cluster is not running, will not delete it. Answer should ben then, No, Yes, Yes.

I agree with the majority saying "Correct answer = No, Yes, Yes" I believe "idle" does not mean offline or non-existent, just "not busy"

Wrong, Should be Yes Yes Yes. My criteria for the first one is that the compute resource is created, that is the cluster, with a vm size of DS12_v2 and max 4 nodes. This compute resource is the cluster definition, not the VM's which are created while used. But, the cluster definition, the Machine Learning Compute Resource IS CREATED. So, Yes, Yes and Yes.

Correct answer No, Yes, Yes You can test this yourself by making a cluster (cpu-cluster) which can scale to zero nodes then running the code below: from azureml.core.compute import ComputeTarget from azureml.core.compute_target import ComputeTargetException cluster_name = "cpu-cluster" try: the_cluster = ComputeTarget(ws, name=cluster_name) print("Cluster with zero nodes ready to use") except ComputeTargetException: print("Failed to reference cluster with zero nodes")
