True or False: When configuring a SOAP client, the contract must be provided in WSDL format.

• A. True
• B. False
• C. It can also be WADL
• D. It can be described by a JSON Schema

Answer: (A)

For SOAP, the service contract is described using WSDL. WSDL defines what operations are available, the structure of the input and output messages, and how those messages are bound to protocols and data types (often using embedded XML Schema). This makes WSDL the standard format that SOAP clients rely on to generate stubs and know how to interact with the service. WADL is intended for RESTful services, not SOAP, and JSON Schema describes JSON payloads used in REST/JSON, not XML-based SOAP. So the statement is true.
