Hello,

Since exclude attribute in WebMethod annotation defaults to false then any method that are not annotated with WebMethod should be exposed as a web service. In the question it requires only getRate method be exposed as a web service so the correct answer should be like getRate need not have an annotation and the other two methods should have a WebMethod(exclude=true) annotation.

As per WS Meta Data Specification Section 3.1, "If a WebMethod annotation is present, only the methods to which it is applied are exposed." Therefore, the methods on which there is no annotation will not be exposed because @WebMethod is present for some methods and so the given answer is correct.
