Through which interface can web or mobile applications integrate with Automation Decision Services to invoke...

The correct answer is D. Web and mobile applications invoke Automation Decision Services decisions through RESTful calls. Automation Decision Services integrates with a CI/CD stack for building and deploying decisions, and web or mobile applications can invoke deployed decisions by using RESTful calls. The decision runtime provides REST APIs for executing decisions, managing deployment spaces, managing decision service archives and metadata, retrieving runtime state, and retrieving execution traces. This REST-based integration model fits cloud-native application architectures because it is lightweight, language-neutral, and compatible with web, mobile, and microservice clients. SOAP Web Service, JMS, and CORBA are not the tested ADS invocation interface. SOAP and JMS are more common in legacy enterprise middleware patterns, while CORBA is not relevant to modern CP4BA decision runtime invocation. Therefore, RESTful calls are the correct integration interface for invoking deployed ADS decision services.
