How do you configure retry policies in Azure Functions?

Short answer: Use Function.json or attributes in C# for retry policies. [FunctionName("QueueRetryFunction")] [FixedDelayRetry(3, "00:00:10")] public static void Run([QueueTrigger("retryqueue")] string message, ILogger log) { log.LogInformation($"Processing message: {message}"); }

Real-world example (ShopNest)

Order-paid events go to Service Bus; an Azure Function sends the confirmation email asynchronously.

Say this in the interview

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
