Actual exam question from Microsoft's DP-100

Question #: 13
Topic #: 3

HOTSPOT -
You are using Azure Machine Learning to train machine learning models. You need a compute target on which to remotely run the training script.
You run the following Python code:

For each of the following statements, select Yes if the statement is true. Otherwise, select No.
NOTE: Each correct selection is worth one point.
Hot Area:

Show Suggested Answer

Suggested Answer:

Box 1: Yes -
The compute is created within your workspace region as a resource that can be shared with other users.

Box 2: Yes -
It is displayed as a compute cluster.

View compute targets -
1. To see all compute targets for your workspace, use the following steps:
2. Navigate to Azure Machine Learning studio.
3. Under Manage, select Compute.
4. Select tabs at the top to show each type of compute target.

Box 3: Yes -
min_nodes is not specified, so it defaults to 0.

2 should be no. 'AmlCompute' refers to compute clusters, not instances: https://learn.microsoft.com/en-us/azure/machine-learning/how-to-create-attach-compute-cluster?view=azureml-api-2&tabs=python Instances require 'ComputeInstance', see https://learn.microsoft.com/en-us/azure/machine-learning/how-to-create-compute-instance?view=azureml-api-2&tabs=python

2 should be No, this script is for training a ml model, that must be a computer instance, the first item in the pic shows. You can't say it's a cluster coz you assign it 'the_cluster_name'.

Box 3 is correct - 0 The minimum number of nodes to use on the cluster. If not specified, defaults to 0. https://learn.microsoft.com/en-us/python/api/azureml-core/azureml.core.compute.amlcompute(class)?view=azure-ml-py

The correct answer is Yes, Yes and No The minimum number of nodes for the compute target created in the above code will default to 1 if you do not specify the min_nodes parameter, not 0

Additional explanation: For box 3, it is 1 and not 0; This means that the compute target will always have at least one node running, even if no jobs are currently scheduled to run on it. The max_nodes parameter, on the other hand, does default to 1 if not specified. This means that by default, the compute target will have a single node, and will not scale up to more nodes automatically.

The default is zero https://learn.microsoft.com/en-us/python/api/azureml-core/azureml.core.compute.amlcompute.amlcomputeprovisioningconfiguration?view=azure-ml-py#parameters

For 2 it will be rather "Compute Instance" than "Compute Cluster" so - NO
