KCNA · Question #51

What is Serverless computing?

The correct answer is A. A computing method of providing backend services on an as-used basis. Serverless computing is a cloud execution model where the provider dynamically manages the server infrastructure, allowing users to run code and pay only for the compute resources consumed on an as-used basis.

Why each option

Serverless computing is a cloud execution model where the provider dynamically manages the server infrastructure, allowing users to run code and pay only for the compute resources consumed on an as-used basis.

AA computing method of providing backend services on an as-used basis.Correct

Serverless computing abstracts away server management, enabling developers to build and run applications without provisioning or managing servers. It operates on a pay-as-you-go model, charging only for the resources consumed during execution, making it ideal for event-driven backend services.

BA computing method of providing services for AI and ML operating systems.

While serverless can be used for AI/ML workloads, it's not exclusively defined by providing services for AI/ML operating systems, which is a mischaracterization of serverless.

CA computing method of providing services for quantum computing operating systems.
DA computing method of providing services for cloud computing operating systems.
