Which Azure Functions hosting plan scales automatically to zero when there is no traffic?
Answer: Consumption plan
The Consumption plan scales to zero when idle and you pay only for execution time and resource consumption.
What attribute marks a C# Azure Function as triggered by an HTTP request?
Answer: [HttpTrigger]
The `[HttpTrigger]` attribute on a function parameter configures the Azure Function to execute on incoming HTTP requests.
In Azure Durable Functions, which function type orchestrates the execution of other functions?
Answer: Orchestrator function
Orchestrator functions define the workflow logic and coordinate calls to activity functions using async/await patterns.
What is the default maximum execution timeout for an Azure Function running on the Consumption plan?
Answer: 10 minutes
On the Consumption plan, Azure Functions default to a 5-minute timeout but the maximum allowed is 10 minutes.
Which file defines the bindings and trigger configuration for an Azure Function in the non-isolated worker model?
Answer: function.json
`function.json` contains the trigger, input binding, and output binding definitions for each Azure Function.
What Durable Functions pattern is used to fan out work across multiple parallel activity functions and then aggregate results?
Answer: Fan-out/fan-in
The fan-out/fan-in pattern starts multiple activity functions in parallel and uses `Task.WhenAll` to wait for all results before aggregating.
