Designing and Implementing a Data Science Solution on Azure

Microsoft DP-100 Sample Questions

Question # 1

You train a model and register it in your Azure Machine Learning workspace. You are ready to deploy the model as a real-time web service. You deploy the model to an Azure Kubernetes Service (AKS) inference cluster, but the deployment fails because an error occurs when the service runs the entry script that is associated with the model deployment. You need to debug the error by iteratively modifying the code and reloading the service, without requiring a re-deployment of the service for each code update. What should you do?

A. Register a new version of the model and update the entry script to load the new version of the model from its registered path. 
B. Modify the AKS service deployment configuration to enable application insights and redeploy to AKS. 
C. Create an Azure Container Instances (ACI) web service deployment configuration and deploy the model on ACI. 
D. Add a breakpoint to the first line of the entry script and redeploy the service to AKS. 
E. Create a local web service deployment configuration and deploy the model to a local Docker container.
