• Question 1:

  A developer is reviewing requirements prior to design of a new system, based on Web services. The requirements state the users of the company's financial systems need extensible request/response messaging. Which two statements are true? (Choose two.)

  A. HTTP is required because SOAP is not extensible without it.
  B. FTP is appealing because it supports two-way communication with SOAP.
  C. SOAP messages can be multicast with SMTP.
  D. HTTPS is supported for financial transactions, but is not recommended for large groups of users.
  E. SOAP could be combined with XML encryption and MTOM to help meet the requirements.
  C. SOAP messages can be multicast with SMTP.
  E. SOAP could be combined with XML encryption and MTOM to help meet the requirements.

• Question 2:

  Which three techniques can be used to apply XML Digital Signatures to an XML document? (Choose three.)

  A. use detached signatures, where the digital signature covers sibling elements or external data
  B. use enveloping signatures, where the digital signature element encloses the data to be signed
  C. use enveloping signatures, where the digital signature is a child element of the data to be signed
  D. use enveloped signatures, where the digital signature is a child element of the data to be signed
  E. use enveloping signatures, where the digital signature element is a child element of the data to be signed
  A. use detached signatures, where the digital signature covers sibling elements or external data
  B. use enveloping signatures, where the digital signature element encloses the data to be signed
  D. use enveloped signatures, where the digital signature is a child element of the data to be signed

• Question 3:

  Enterprise A invokes a Web service provided by enterprise B with some parameters, and receives a response. A developer is making this interaction asynchronous so that A does not have to wait for B to finish processing. Which two actions must be taken to fulfill this requirement? (Choose two.)

  A. establish a Web service endpoint for enterprise A to receive the response
  B. partition the endpoint implementation in to interaction and processing layers so responses can be received independently
  C. convert all Web service methods to use XML documents as parameters and return values
  D. embed a correlation identifier in the request so that enterprise B can associate the response with it
  E. read messages from a queue populated by enterprise B at peak hours when response times are too slow
  A. establish a Web service endpoint for enterprise A to receive the response
  D. embed a correlation identifier in the request so that enterprise B can associate the response with it

• Question 4:

  A Java client, running behind a firewall, needs to connect to a UDDI registry that is deployed outside the firewall. The client is using the Java EE 5 implementation of JAXR. The client creates a set of properties that specify the proxy host and port information for the network in which the client is running. What are the remaining steps required by the JAXR client to connect to the UDDI registry?

  A. assign the properties to a connection factory and create the connection
  B. specify the URL of the UDDI registry in the properties, assign the properties to a connection factory, and create the connection
  C. specify the URL of the UDDI registry in the properties, assign the properties to a connection factory, assign the properties to a service binding, and create the connection
  D. specify the URL for the UDDI registry and the tModel in the properties, specify the search criteria for services, assign the properties to a service binding, and create the connection
  B. specify the URL of the UDDI registry in the properties, assign the properties to a connection factory, and create the connection

• Question 5:

  Which three statements about parsers are true? (Choose three.)

  A. SAX and StAX are bi-directional.
  B. DOM and StAX are bi-directional.
  C. StAX is a push API, whereas SAX is pull.
  D. SAX is a push API, whereas StAX is pull.
  E. SAX and StAX are read-only.
  F. SAX and DOM can write XML documents.
  G. StAX and DOM can write XML documents.
  B. DOM and StAX are bi-directional.
  D. SAX is a push API, whereas StAX is pull.
  G. StAX and DOM can write XML documents.

• Question 6:

  A developer created a Web service client that sends requests to the company's inventory service. The quality assurance team reports a problem during testing. The client does not work in some cases and the QA team reports that the client is sending malformed SOAP messages. The software is returned to the developer for resolution.

  What is the result?

  A. One or more class cast exceptions are returned in a SOAP message.
  B. A SOAP fault that surfaces as a HTTPException because SOAP is serializable.
  C. A SOAP fault surfaces as a SOAPFaultException.
  D. A generic exception results because Java details are not to be mingled with SOAP.
  C. A SOAP fault surfaces as a SOAPFaultException.

• Question 7:

  A developer is writing a Web service method that needs to accept multiple types of requests. Based on the request's content, the service performs time-consuming steps, such as verifying the user's account, checking credit ratings, and building a list of offers. Which two approaches are appropriate to use in this situation? (Choose two.)

  A. a synchronous, document-style approach
  B. a synchronous, procedure-style approach
  C. an asynchronous, document-style approach
  D. an asynchronous, procedure-style approach
  E. HTTP and HTTPS
  F. SMTP or other asynchronous protocol
  C. an asynchronous, document-style approach
  F. SMTP or other asynchronous protocol

• Question 8:

  A developer must describe a message that contains multiple parts using non-primitive data types. Which two code fragments produce equivalent composite message structure definitions? (Choose two.)

  A. . .
  B. . .
  C. .
  D. .
  B. . .
  D. .

• Question 9:

  A developer has been implementing a Java application that reads in pharmaceutical information via Web service calls, scans through the data, and presents warnings about possible drug interactions. Performance has been slow, due to the large payloads returned from the Web services. Which two statements are true about implementing the Web Service Cache pattern? (Choose two.)

  A. Caching must occur on the server.
  B. Caching can occur on the client.
  C. It will improve performance of updates.
  D. It encapsulates a request as an object.
  E. It will improve performance for non-volatile data.
  B. Caching can occur on the client.
  E. It will improve performance for non-volatile data.

• Question 10:

  A document-style service defines a document passed to the Web service using xsd:anyType in the WSDL file that describes the service. How should the document be typed in Java?

  A. use javax.xml.soap.Element
  B. use javax.xml.soap.Node
  C. use javax.xml.soap.SOAPHeader
  D. use javax.xml.soap.SOAPElement
  E. use javax.xml.soap.SOAPFault
  F. use javax.xml.soap.SOAPBodyElement
  D. use javax.xml.soap.SOAPElement
