CCSK Security Guide pg 11: Platform as a Service (PaaS) abstracts and provides development or application platforms,such as databases, application platforms (e.g. a place to run Python, PHP, or other code), file storage and collaboration, or even proprietary application processing (such as machine learning, big data processing, or direct Application Programming Interfaces (API) access to features of a full SaaS application). The key differentiator is that, with PaaS, you don’t manage the underlying servers, networks, or other infrastructure.

It's PaaS, we're talking about more than access to SW (SaaS), but not something barebones (IaaS). That's how I read it and would answer PaaS on the test.

of course the correct answer is PaaS. Despite some SaaS providers provides API interfaces to help the automation, but these don't mean direct access to the databases or to the backend application stack.

I was wrong. The right answer is the "A"

Software as a Service (SaaS) is a full application that’s managed and hosted by the provider. Consumers access it with a web browser, mobile app, or a lightweight client app

SaaS, They don't provide you any infra

The key differentiator is that, with PaaS, you don’t manage the underlying servers, networks, or other infrastructure. Answer is correct, A

It is SaaS

SaaS enables companies to provide client-based access for partners to databases or applications. In this model, software applications are hosted on the cloud, and users access them through web browsers. SaaS providers typically manage and maintain the underlying infrastructure, application, and data, which allows companies to focus on their core business rather than managing software and hardware.
