A. B. C. D. E.Correct Answer: D
When you need to run the long-term workflows, you should use the Azure Durable Functions.
The Durable Function is an extension of the Azure Functions.
The function provides a cost-effective serverless approach for running stateful long-running, complex workflows.
The Durable Function can chain, orchestrate, and coordinate the functions.
This Azure service manages the state.
Therefore, the developers do not need to write the code to manage the state for long-running functions.
There are three Durable Function types: Client, Orchestration, and Activity.
The Durable Functions implement several common workflow patterns: Function chaining - execution of the multiple functions in a specific order.
Fan out/fan in - a run of the multiple functions in parallel till every function finishes its execution.
Async HTTP APIs - coordination of the long-running operations with the external clients.
Monitor - a recurrent process until specific conditions are met.
Human interaction - a combination of human interaction with automated processes.
Aggregator - an aggregation of the several data streams from different data sources and possibly during long time periods into one function.
Option D is correct because the Human interaction pattern is a combination of human interaction with automated processes, like waiting for the document approval from a person.
This pattern involves four functions:
A request for approval task.
An assignment of the task to the person.
A process of approval.
An escalation process.

The Azure Durable Functions is a serverless compute platform that allows you to write stateful functions in a serverless environment. It provides a way to create long-running workflows and stateful entities by allowing functions to be triggered by events and to communicate with each other through messages.
To create an approval process for SharePoint documents using Azure Durable Functions, you should consider the "Human Interaction" application pattern. This pattern allows you to incorporate human interaction into your application by creating a workflow that requires user input at certain points.
In this pattern, the approval process can be initiated by a user or by an automated process. When the approval process is initiated, a durable function is triggered, which creates an approval workflow. The workflow includes tasks that require human interaction, such as reviewing the document and providing approval or rejection.
The workflow can be implemented using a combination of Azure Durable Functions and SharePoint APIs. The Durable Functions can orchestrate the workflow by triggering SharePoint APIs to get the necessary document details, create approval tasks, and update the document status based on the user's response.
In summary, the "Human Interaction" application pattern should be considered for creating an approval process for SharePoint documents using Azure Durable Functions. This pattern allows you to incorporate human interaction into your application by creating a workflow that requires user input at certain points, which can be implemented using a combination of Azure Durable Functions and SharePoint APIs.
