If a Service Can Have One or More Service Capabilities

question 24

Multiple Choice

If a service can have one or more service capabilities, then how can a service consumer interact with a service?

• A) It can't. The service must only provide one service capability in order for it to be accessible by service consumers.
• B) Each service capability represents a function that the service has to offer. The service consumer can invoke and interact with one service capability at a time, thereby only using a subset of the service's overall functionality.
• C) Service capabilities are designed to be composed together, which means that in order for a service consumer to interact with a service, it must be designed to invoke all of its service capabilities at the same time.
• D) Services do not have service capabilities that are explicitly invoked. Services almost always exist as event-driven programs that transparently intercept service consumer messages at runtime.
