AZ-204 Developing for Microsoft Azure Exam Prep - Durable Functions

The video tutorial introduces durable functions in Azure, explaining their purpose and components like the starter, orchestrator, and tasks. It guides viewers through creating these functions in Azure, executing them, and testing their output. The tutorial emphasizes asynchronous execution and checking the status of functions. It concludes with a discussion on design patterns for durable functions, encouraging further learning.

What is the primary role of the orchestrator in a durable function?

• To execute the starter function

• To manage and invoke other functions

• To handle HTTP requests

• To install necessary extensions

What is the first step in setting up a durable function in Azure?

• Writing the function code

• Defining the activity function

• Installing durable extensions

• Creating the orchestrator function

Which function is responsible for taking an HTTP trigger in a durable function setup?

• Starter function

• Activity function

• Orchestrator function

• Worker function

In the context of durable functions, what does the orchestrator function do?

• It returns a static response

• It handles HTTP requests

• It calls the activity functions

• It installs extensions

What is the purpose of the activity function in a durable function setup?

• To manage the execution of other functions

• To perform specific tasks as directed by the orchestrator

• To trigger the orchestrator

• To handle HTTP requests

How can you check the status of a running durable function?

• By using the status query URL

• By checking the function logs

• By restarting the function

• By re-running the starter function

Which design pattern involves a function calling multiple other functions and then aggregating their results?

• Event sourcing

• Fan-out/fan-in

• Singleton

• Chaining
