Exam DP-100 topic 4 question 11 discussion

Actual exam question from Microsoft's DP-100
Question #: 11
Topic #: 4
[All DP-100 Questions]

HOTSPOT -
You use Azure Machine Learning to train and register a model.
You must deploy the model into production as a real-time web service to an inference cluster named service-compute that the IT department has created in the
Azure Machine Learning workspace.
Client applications consuming the deployed web service must be authenticated based on their Azure Active Directory service principal.
You need to write a script that uses the Azure Machine Learning SDK to deploy the model. The necessary modules have been imported.
How should you complete the code? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

Suggested Answer:
Box 1: AksCompute -
Example:
aks_target = AksCompute(ws,"myaks")
# If deploying to a cluster configured for dev/test, ensure that it was created with enough
# cores and memory to handle this deployment configuration. Note that memory is also used by
# things such as dependencies and AML components.
deployment_config = AksWebservice.deploy_configuration(cpu_cores = 1, memory_gb = 1) service = Model.deploy(ws, "myservice", [model], inference_config, deployment_config, aks_target)

Box 2: AksWebservice -

Box 3: token_auth_enabled=Yes -
Whether or not token auth is enabled for the Webservice.
Note: A Service principal defined in Azure Active Directory (Azure AD) can act as a principal on which authentication and authorization policies can be enforced in
Azure Databricks.
The Azure Active Directory Authentication Library (ADAL) can be used to programmatically get an Azure AD access token for a user.
Incorrect Answers:
auth_enabled (bool): Whether or not to enable key auth for this Webservice. Defaults to True.

given answer is correct token_auth_enabled bool default value: None Whether or not to enable Token auth for this Webservice. If this is enabled, users can access this Webservice by fetching an access token using their Azure Active Directory credentials. Defaults to False. https://docs.microsoft.com/en-us/python/api/azureml-core/azureml.core.webservice.akswebservice?view=azure-ml-py Service principal: You create a service principal account in Azure Active Directory, and use it to authenticate or get a token. A service principal is used when you need an automated process to authenticate to the service without requiring user interaction. For example, a continuous integration and deployment script that trains and tests a model every time the training code changes. https://docs.microsoft.com/en-us/azure/machine-learning/how-to-setup-authentication

Given answer is correct. The third one might be confusing for some people but here is what Microsoft documentation says: token_auth_enabled: Whether or not to enable Token auth for this Webservice. If this is enabled, users can access this Webservice by fetching an access token using their Azure Active Directory credentials. Defaults to False.
