Demo Questions

Question 1
A SOAP-based Web service is essentially:
  1. solution logic that can only be accessed via HTTP methods
  2. solution logic accessible via binary RPC protocols
  3. solution logic that has been shaped by service-orientation design principles
  4. solution logic that can be accessed via a published WSDL definition
Correct answer: D
Question 2
Which of the following statements is false?
  1. The WS-I is an industry standards organization that provides basic profiles to help foster interoperability among solutions based on XML and Web services industry standards.
  2. OASIS is an industry standards organization that has developed a number of important technology specifications, including WS-BPEL and UDDI.
  3. The W3C is a standards organization that has developed a number of important technology specifications, including SOAP, WSDL, and WS-Addressing.
  4. The OAS-C is an industry standards organization that has developed a number of important technology specifications, including WS-Security and XML Schema.
Correct answer: D
Question 3
Which of the following statements is true?
  1. When using WS-AtomicTransaction, services participating in a transaction vote on the outcome so as to communicate whether the transaction should be rolled back or committed.
  2. When using WS-AtomicTransaction, services participating in a transaction use RPC protocols to communicate transaction results, so as to communicate whether the transaction should be rolled back or committed.
  3. When using WS-AtomicTransaction, services participating in a transaction rely on the use of WS-Policy definitions to confirm the transaction results.
  4. When using WS-AtomicTransaction, services do not actually participate in a transaction. This specification governs intra-service transactions (transactions that occur within a service boundary) only. WS-BusinessActivity provides cross-service transaction protocols.
Correct answer: A

  2. I built 3 XML schemas, two of which are being shared by the same WSDL definition.
  3. I built 3 WSDL definitions and 3 XML schemas. Each WSDL definition is associated with its own XML schema.

Question 8
Which of the following statements is true?
  1. WS-ReliableMessaging establishes a framework that provides an industry-standard means of transforming XML schema-based data models.
  2. WS-ReliableMessaging establishes a framework that provides an industry-standard means of rolling back changes that occur during a runtime service transaction.
  3. WS-ReliableMessaging establishes a framework that provides an industry-standard means of reliably communicating policy enforcement rules.
  4. None of these statements are true.
Correct answer: D
Question 9
XSLT is a technology that is primarily used to address _____________________.
  1. technology protocol bridging requirements (such as when .NET and Java components need to speak to each other)
  2. data model transformation requirements (such as when similar data based on different XML schemas needs to be exchanged)
  3. layer transformation requirements (such as when data located in different architectural layers needs to be exchanged between architectural layers)
  4. service transformation requirements (such as when two versions of the same service exist)
