In which products must you use the ABAP Cloud Development Model? Select the two correct answers.

The ABAP Cloud Development Model is specifically designed for cloud environments where the application lifecycle management and development processes benefit from cloud-native capabilities. The correct answer includes the SAP BTP (Business Technology Platform), ABAP environment, which fully supports the ABAP Cloud Development Model. This platform allows developers to build, deploy, and manage ABAP applications in a cloud environment, leveraging modern software practices and technologies.

In addition, SAP S/4HANA Cloud, public edition is also a correct choice as it relies on a SaaS (Software as a Service) model that is inherently geared toward cloud development practices, facilitating rapid deployment, integration, and scalability that align with the ABAP Cloud Development Model.

The other choices, while they may allow for ABAP development, do not primarily utilize the cloud-centric features of the ABAP Cloud Development Model. SAP S/4HANA Cloud, private edition and SAP S/4HANA on premise are more traditional models that do not exclusively focus on the cloud development paradigm and therefore do not require the ABAP Cloud Development Model for their primary operations.
