SOA S90-02A Online Questions & Answers

• Question 51:

  Identify what is wrong with the following statement: "I have a single Calculator component that provides basic math functions. I'm exposing this component as a component-based service for internal service consumers that are also component-based. I'm exposing this component as a SOAP-based Web service for internal and external service consumers that support SOAP messaging. I'm also exposing this component as a REST service for external service consumers that prefer to access its functions via HTTP methods. I'm also exposing this component as a service agent for service consumers that support explicit invocation via a service contract." SELECT ALL THAT APPLY

  A. A single component cannot be exposed as a component-based service, a SOAP-based Web service and a REST service at the same time.
  B. SOAP-based Web service consumer programs cannot be both internally and externally located.
  C. The uniform contract required by REST services does not support the use of HTTP methods.
  D. Service agents are event-driven and are therefore not explicitly invoked via a service contract.
  D. Service agents are event-driven and are therefore not explicitly invoked via a service contract.

• Question 52:

• Question 53:

  Which of the following technologies are fundamental to REST service design? SELECT ALL THAT APPLY

  A. HTTP
  B. WSDL
  C. MEP
  D. RPC
  A. HTTP

• Question 54:

  Which of the following service designs are considered not supportive of service-orientation due to improper selection of technologies? SELECT ALL THAT APPLY

  A. A REST service designed to respond to service consumers via standard HTTP response codes.
  B. A SOAP-based Web service designed with a service contract that includes WS-Policy definitions that disallow communication using SOAP messages.
  C. A reusable component-based service designed to reject messages containing XML so as to limit communication to RPC-centric MEPs.
  D. A SOAP-based Web service designed with a decoupled service contract that includes a standardized XML schema.
  B. A SOAP-based Web service designed with a service contract that includes WS-Policy definitions that disallow communication using SOAP messages.
  C. A reusable component-based service designed to reject messages containing XML so as to limit communication to RPC-centric MEPs.

• Question 55:

  A SOAP-based Web service is required to transmit an XML-based invoice document to a REST service. However, the SOAP-based Web service is designed to represent invoice data using an XML schema that is different from the XML schema used within the REST service. How can the disparity between the XML schemas, used by these two services, be overcome so that they can exchange the invoice document? Select the correct answer.

  A. A layer of data format transformation logic needs to be introduced based on mashup technologies, such as DTD and WS-Transform.
  B. A layer of protocol transformation logic needs to be introduced based on Web technologies, such as HTTP and FTP.
  C. A layer of data model transformation logic needs to be introduced, based on XML technologies, such as XSLT.
  D. There is no technique or technology for overcoming differences between XML schemas.
  C. A layer of data model transformation logic needs to be introduced, based on XML technologies, such as XSLT.

• Question 56:

  Which of the following statements is false? Select the correct answer.

  A. Services built as components can expose a non-industry-standard technical service contract.
  B. Services built as components can be assembled into service compositions.
  C. Services built as components always have a decoupled service contract that exists as a physically separate XML document.
  D. Services cannot be built as components.
  C. Services built as components always have a decoupled service contract that exists as a physically separate XML document.

• Question 57:

  XML schemas are comparable to database records. Therefore, XML documents that are based on XML schemas are comparable to database data models. Select the correct answer.

  A. True
  B. False
  B. False

• Question 58:

  Which of the following statements is true? Select the correct answer.

  A. One way in which REST services are different from components is that components each expose their own technical interface (or technical contract), whereas REST services share a single uniform contract.
  B. One way in which REST services are different from components is that components typically exchange data using HTTP, whereas REST services typically exchange data using binary protocols.
  C. One way in which REST services are different from components is that components cannot themselves become services. Instead, components are used by services, such as REST services.
  D. One way in which REST services are different from components is that components cannot exchange data remotely (across server boundaries), whereas REST services are designed to be distributed.
  A. One way in which REST services are different from components is that components each expose their own technical interface (or technical contract), whereas REST services share a single uniform contract.

• Question 59:

  Which of the following statements is true? Select the correct answer.

  A. WS-Policy allows for the definition of policies that can be ignored by service consumers.
  B. WS-Policy allows for the definition of procedure-related policies that can be attached to database tables.
  C. WS-Policy allows for the definition of MEP policies that are limited to outbound MEPs only.
  D. None of these statements are true.
  A. WS-Policy allows for the definition of policies that can be ignored by service consumers.

  B. XQuery
  C. XSLT
  D. XWeb
  B. XQuery
  C. XSLT
