While Azure offers prebuilt receipts and invoices in the Form Recognizer service, you need to extract data from the forms specific to your business. Hence, you decide to use custom models of Form Recognizer in Azure. You further utilize these custom models into a custom skill interface of your enrichment pipeline. Given the steps below, sequence them in the correct order of execution to create, use and manage your custom model in Form Recognizer: Step 1: Manage your custom models.
Step 2: Use the Azure Blob container to upload training data.
Step 3: Establish your training dataset.
Step 4: Use labeled or unlabeled datasets to train the model.
Step 5: Test the model using a dataset not used in training.
Step 6: Create a custom skill and use it in the enrichment pipeline.
 

Answer options:

A.Step 1 -> Step 2 -> Step 4 -> Step 3 -> Step 5 
B.Step 3 -> Step 2 -> Step 4 -> Step 5 -> Step 1
C.Step 1 -> Step 3 -> Step 2 -> Step 4 -> Step 5
D.Step 3 -> Step 2 -> Step 1 -> Step 4 -> Step 5

Correct Answer: B
Option A is incorrect because you will manage your model once it is created, trained and tested. You would also need to upload at least five forms for the training dataset before proceeding with the next steps in the execution process. 
Option B is correct. Here is the correct order of executions steps:
Step 1: Establish your training dataset.
Step 2: Use the Azure Blob container to upload training data.
Step 3: Use labeled or unlabeled datasets to train the model.
Step 4: Test the model using a dataset not used in training.
Step 5: Manage your custom models.
Once you have created the custom model in Form Recognizer, you can create a custom skill and use it in the AI enrichment pipeline of Cognitive Search solution to analyze documents. Option C is incorrect because you will manage your model once it is created, trained and tested.
Option D is incorrect because you will manage your model once it is created, trained and tested.
