(2) What communication protocol is directly used by the WSDL Web services for transferring data?
A) SOAP

(3) If you want to create a standard service broker with both service directory and service repository, what standard should be used?
A) ebXML

(4) What protocol in the Web services protocol stack is normally in the layer directly below the SOAP protocol?
A) HTTP

Answer 1

HTTP is used for accessing RESTful services, SOAP is used for transferring data in WSDL Web services, ebXML is used for creating a standard service broker, and HTTP is below the SOAP protocol in the Web services protocol stack.

Step-by-step explanation:

The communication protocol used for accessing RESTful services is HTTP. RESTful services are web services that follow the principles of Representational State Transfer (REST), which uses the HTTP protocol for communication.

The communication protocol directly used by the WSDL Web services for transferring data is SOAP. SOAP (Simple Object Access Protocol) is a protocol that allows programs running on different operating systems to communicate with each other via HTTP and XML.

If you want to create a standard service broker with both service directory and service repository, the standard that should be used is ebXML. ebXML (Electronic Business using eXtensible Markup Language) is a set of standards that enable the exchange of business messages, collaboration, and discovery of services over the Internet.

The protocol in the Web services protocol stack that is normally in the layer directly below the SOAP protocol is HTTP. HTTP is the underlying protocol for transferring data and is commonly used in conjunction with SOAP for communication between web services.
