A __________________ establishes a common access point generally based on HTTP methods used by __________________. Select the correct answer.

Question

Options

• AWSDL definition, SOAP-based Web service
• Buniform contract, REST services
• CXML schemas, components
• DNone of the above

• A
  2% (1)
• B
  88% (36)
• C
  2% (1)
• D
  7% (3)

Explanation

Option B is correct because REST (Representational State Transfer) services use a uniform contract - a consistent interface built around standard HTTP methods (GET, POST, PUT, DELETE, PATCH) that all clients and servers agree upon, creating a common, predictable access point regardless of the underlying implementation.

Option A is wrong because WSDL (Web Services Description Language) defines the interface for SOAP-based services, not a "common access point based on HTTP methods" - SOAP has its own protocol envelope and is not HTTP-method-driven in the same way REST is.

Option C is wrong because XML schemas define the structure and validation rules for XML data; they are not access point mechanisms, nor do they govern how services are called.

Memory tip: Think REST = HTTP verbs = Uniform Contract. The word "uniform" is actually borrowed directly from REST's formal architectural constraint: the Uniform Interface. If you remember "REST enforces a uniform interface via HTTP methods," option B will always stand out.
