Exam AI-100 topic 2 question 43 discussion

Actual exam question from Microsoft's AI-100

Question #: 43
Topic #: 2

HOTSPOT -
You are designing an Azure infrastructure to support an Azure Machine Learning solution that will have multiple phases. The solution must meet the following requirements:
✑ Securely query an on-premises database once a week to update product lists.
✑ Access the data without using a gateway.
✑ Orchestrate the separate phases.
What should you use? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

Suggested Answer: Incorrect Answer: The VPN connection solution both use gateways.
Box 1: Azure App Service Hybrid Connections
With Hybrid Connections, Azure websites and mobile services can access on-premises resources as if they were located on the same private network. Application admins thus have the flexibility to simply lift-and-shift specific most front-end tiers to Azure with minimal configuration changes, extending their enterprise apps for hybrid scenarios.
Box 2: Machine Learning pipelines
Typically when running machine learning algorithms, it involves a sequence of tasks including pre-processing, feature extraction, model fitting, and validation stages. For example, when classifying text documents might involve text segmentation and cleaning, extracting features, and training a classification model with cross-validation. Though there are many libraries we can use for each stage, connecting the dots is not as easy as it may look, especially with large-scale datasets. Most ML libraries are not designed for distributed computation or they do not provide native support for pipeline creation and tuning.

Box 3: Azure Databricks -

If you agree that the second box is pipelines then the third box makes sense. Look up the second URL give which points to the Databricks documentation for pipelines

The third answer should be azure automation. Control orchestrating using Azure Automation - which ties into an MLOps/DevOps/Continous Integration/Continous delivery approach.

it should be automation, Azure Automation provides complete control during deployment, operations, and decommissioning of workloads and resources https://opdhsblobprod01.blob.core.windows.net/contents/4a6d75bb3af747de838e6ccc97c5d978/c04062585e59c060681bb6b6b0606102?sv=2015-04-05&sr=b&si=ReadPolicy&sig=Nd4YY3g5M9bQ940ineEqNQcir0hS%2Bz8umM6bAoOlDso%3D&st=2020-03-22T16%3A53%3A36Z&se=2020-03-23T17%3A03%3A36Z

You need to understand "orchestrate multiple phases" of what! Read up what Azure Automation can do and you'll know what I mean. Agree with Bharat's comment. Summary: Databricks controls the orchestrations through ML Pipelines. Given answer is correct. Given answer is correct.
