Microsoft DP-100 Exam - Topic 2 Question 12 Discussion

Actual exam question for Microsoft's DP-100 exam

Question #: 12
Topic #: 2

You are a lead data scientist for a project that tracks the health and migration of birds. You create a multi-class image classification deep learning model that uses a set of labeled bird photographs collected by experts.

You have 100,000 photographs of birds. All photographs use the JPG format and are stored in an Azure blob container in an Azure subscription.

You need to access the bird photograph files in the Azure blob container from the Azure Machine Learning service workspace that will be used for deep learning model training. You must minimize data movement.

What should you do?

ACreate an Azure Data Lake store and move the bird photographs to the store.

BCreate an Azure Cosmos DB database and attach the Azure Blob containing bird photographs storage to the database.

CCreate and register a dataset by using TabularDataset class that references the Azure blob storage
containing bird photographs.

DRegister the Azure blob storage containing the bird photographs as a datastore in Azure Machine Learning service.

ECopy the bird photographs to the blob datastore that was created with your Azure Machine Learning
service workspace.

Show Suggested Answer

Suggested Answer: D

We recommend creating a datastore for an Azure Blob container. When you create a workspace, an Azure blob container and an Azure file share are automatically registered to the workspace.

I’m surprised they didn’t mention using a dataset class!

Wait, why not just use the existing blob storage directly?

Moving files to a Data Lake seems unnecessary.

You can register the blob storage as a datastore.

I remember that registering the blob storage directly in Azure ML was emphasized as a good practice. It seems like option D could be the right choice here.

I think moving the photographs to a Data Lake store is not ideal since it increases data movement, but I can't recall the exact reasons.

I remember we discussed minimizing data movement in class, so I think registering the blob storage as a datastore might be the best option.

I'm not entirely sure, but I feel like creating a dataset with the TabularDataset class could also work. It seems similar to a practice question we did.

I've got a good feeling about option A. The question states the operation takes effect for the entire meeting, so extending the meeting seems like the logical choice.

Okay, I think I've got this. The key is to look for the BGP configuration that enables the sending of IPv4 labels to build inter-domain LSPs. Let me double-check the options.

Remembering from our study session, I might lean towards option A since it emphasizes checking the routing protocols, right?

I know for sure it's not access list therapy, but the specifics about Layer 2 versus Layer 3 are a bit fuzzy for me.
