Module 4-6

You have a reference to a Workspace named ws.

Which code retrieves the default datastore for the workspace?

• default_ds = Datastore.get(ws, 'default')

• default_ds = ws.Datastores[0]

• default_ds = ws.get_default_datastore()

A datastore contains a CSV file of structured data that you want to use as a Pandas dataframe.

Which kind of dataset should you create to make it easy to do this?

• A file dataset

• A tabular dataset

You want a script to stream data directly from a file dataset.

Which mode should you use?

• as_mount()

• as_download()

• as_upload()

You need to create an environment from a Conda configuration (.yml) file.

Which method of the Environment class should you use?

• create_from_conda_specification

• create

• create_from_existing_conda_environment

You need to run a training script on compute that scales on-demand from 0 to 3 GPU-based nodes.

Which kind of compute target should you create?

• Compute Instance

• Compute Cluster

• Inference Cluster

Which ScriptRunConfig parameter causes the script to run on a compute cluster named train-cluster?

• arguments=['--AmlCluster', 'train-cluster']

• environment='train-cluster'

• compute_target='train-cluster'

What type of object should you use to pass data between pipeline steps?

• PipelineData

• Datastore

• Dataset

You plan to use the Schedule.create method to create a schedule for a published pipeline.

What kind of object must you create to configure how frequently the pipeline runs?

• ScheduleRecurrance

• PipelineParameter

• Datastore

You want to deploy the model as a containerized real-time service with high scalability and token-based security.

What kind of deployment target should you use?

• An Azure Container Instance (ACI)

• An Azure Kubernetes Service (AKS) inference cluster

• A multi-node compute cluster with GPUs

• An Azure ML Compute Cluster

Which functions must the entry script for a real-time service implement?

• init and run

• main and score

• load and predict
