Microsoft Azure Architect Design (AZ-301) Practice Exam

Question: 1 / 400

What best describes Azure Function's billing model?

You pay only for the compute resources used during execution

Azure Functions operates on a consumption-based billing model, meaning that you are charged solely for the compute resources consumed during the execution of your function. This model allows you to only pay for the actual usage rather than incurring costs for idle resources, which can be particularly cost-effective for event-driven applications that may have unpredictable workloads.

This approach scales automatically with the volume of incoming events, ensuring that you are not paying for excess computing power that is not being utilized, making option A the most accurate description of Azure Functions' billing model. This flexibility is one of the key advantages of serverless architecture, which allows developers to focus on writing code without worrying about the underlying infrastructure and its associated costs.
