• Question 37:

  Using WS-AtomicTransaction you wrap 3 SOAP-based Web services in a single transaction.

• Question 40:

  Identify what is wrong with this statement: "If I have 4 SOAP-based Web services, I must have 4 WSDL definitions and 4 XML schemas." Select the correct answer.

  A. SOAP-based Web services don't use XML schemas for their WSDL definitions.
  B. WSDL definitions can share the same XML schema and can also link to multiple XML schemas, so stating that 4 SOAP-based Web services must have 4 XML schemas is incorrect.
  C. Each WSDL definition must have at least 2 XML schemas, so the correct amount of required XML schemas in this case is 8.
  D. There is nothing wrong with this statement.
  B. WSDL definitions can share the same XML schema and can also link to multiple XML schemas, so stating that 4 SOAP-based Web services must have 4 XML schemas is incorrect.
