Which of the following statements is true?

An initial sender is at the beginning of the message path, whereas the service consumer is at the end of

Identify what is wrong with this statement: "Component A invoked SOAP-based Web Service B, which invoked REST Service C."

Components cannot invoke SOAP-based Web services. A SOAP-based Web service can only be
invoked by another SOAP-based Web service. SOAP-based Web services cannot invoke REST services. A REST service can only be invoked byanother REST service. Because they require different transport protocols, the same data cannot be sent from a component to aSOAP-based Web service and then to a REST service. There is nothing wrong with this statement.

9.

Which of the following statements is true?

A service enters the service provider role when it initiates contact with other services, including those

that act as intermediaries. A service enters the service provider role when it initiates contact with intermediaries only. A service enters the service provider role when it is accessed by other service consumers, includingintermediaries. A service enters the service provider role when it is accessed by intermediaries only.
