Which term refers to a registry listing all available web services?

• A. WSDL
• B. RESTful
• C. Service Registry
• D. UDDI

Answer: (C)

In web services discovery, the term that refers to a registry listing all available services is UDDI, which stands for Universal Description, Discovery, and Integration. UDDI acts as a directory where publishers can publish their service details (like endpoints and interfaces) and clients can search for and bind to services that meet their needs. WSDL describes a single service’s interface and how to interact with it, not a registry of all services. RESTful is an architectural style for designing services, not a discovery mechanism. A service registry is a general concept for registering services, but UDDI is the established registry standard specifically associated with listing and discovering web services.
