• Question 81:

  A developer is analyzing an existing Web service with performance problems. The analysis reveals the service employs SOAP over HTTP. When the size of the encoded binary files grew with changing business requirements, the service slowed. What are two effective solutions for this problem? (Choose two.)

  A. Separating the XML and binary content with WS-Filtering implemented in WSIT will improve efficiency.
  B. XML documents larger than 1 KB with binary encoding should be optimized.
  C. WS-Addressing can ease congestion by routing messages over other protocols.
  D. For existing services, the most effective solution is to increase the available bandwidth.
  E. MTOM can reduce both processing and bandwidth required by SOAP with attachments.
  B. XML documents larger than 1 KB with binary encoding should be optimized.
  E. MTOM can reduce both processing and bandwidth required by SOAP with attachments.

• Question 82:

  A Web service needs to encrypt certain SOAP headers when responding. Which statement about this encryption?

  A. The Web service interaction layer is the appropriate place for such encryption.
  B. The Web service processing layer is the appropriate place for such encryption.
  C. Either the Web service interaction or processing layer is appropriate for such encryption.
  D. Neither the Web service interaction nor processing layer is appropriate for such encryption.
  E. Protocol-based encryption like HTTPS should be used to meet the requirements without code changes.
  A. The Web service interaction layer is the appropriate place for such encryption.

  D. The class must not be final or abstract.
  F. It can be declared an EJB via the @Stateless annotation.

• Question 85:

  What is an accurate description of the handling of application exceptions thrown by a JAX- WS service endpoint?

  A. Application exceptions can be mapped to faults in WSDL.
  B. Application exceptions are NOT handled by JAX-WS clients.
  C. Application exceptions are always propagated to JAX-WS clients as RemoteExceptions.
  D. Application exceptions are always propagated to JAX-WS clients as WebServiceExceptions.
  E. Application exceptions are always propagated to JAX-WS clients as SOAPFaultExceptions.
  A. Application exceptions can be mapped to faults in WSDL.

• Question 86:

  What are two features of a WSDL 1.1 document? (Choose two.)

  A. Service defines a collection of related endpoints.
  B. Service describes the message's payload using XML.
  C. Service assigns an Internet address to a specific binding.
  D. Porttype declares complex data types and elements used elsewhere.
  E. Porttype elements are used to group a set of abstract operations.
  F. Porttype defines a concrete protocol and data format specification.
  A. Service defines a collection of related endpoints.
  E. Porttype elements are used to group a set of abstract operations.

• Question 87:

  Which statement is true about the SOAP 1.1 actor attribute?

  A. It is ignored for HTTP.
  B. It indicates the recipient of a header block.
  C. It indicates the final recipient of the message.
  D. It indicates which recipient processes the Body element.
  E. SOAP 1.1 does not use the actor attribute.
  B. It indicates the recipient of a header block.

• Question 88:

  Given the Java fragment and schema:

  1.

  //-- Java code fragment

  2.

  public enum USState {MA, NH}

  3.

  //-- Schema fragment

  4.

  5.

  6.

  7.

  8.

  9.

  10.

  // .NET auto generated code from schema

  11.

  public enum usState { NH, MA }

  Which statement is true about .Net and WCF interoperability for this data?

  A. Based on the fragment, enumerations map well between Java and .Net.
  B. The subtle differences in the variable names make it clear these enumerations are NOT interoperable.
  C. The XML schema reveals the type on the enumeration is lost across the platforms.
  D. This exchange would be interoperable if the annotation @XmlEnum was applied to the Java method.
  A. Based on the fragment, enumerations map well between Java and .Net.

• Question 89:

  Which two statements are true about JAXR support for XML registries? (Choose two.)

  A. The CapabilityProfile tells a client the capability level of a registry.
  B. UDDI registries must support ebXML to be compatible with JAXR.
  C. The UnsupportedCapabilityException is processed for errors from non-Java providers.
  D. The JAXR API declares methods as level 0 or level 1.
  E. JAXR registry clients present an XML schema that defines the infomodel for the provider.
  A. The CapabilityProfile tells a client the capability level of a registry.
  D. The JAXR API declares methods as level 0 or level 1.

• Question 90:

  A purchase order Web service is designed to be synchronous, request-response, and HTTP- based. The existing service processes the request immediately. Because of new business requirements, the service can take up to ten days to perform a credit check before processing the order. Which two design changes need to be made? (Choose two.)

  A. The client needs to use dynamic proxies instead of stubs.
  B. The client needs to develop and deploy a Web service to accept callbacks.
  C. The service only needs to change the WSDL from rpc-literal to document-literal.
  D. The client and the service need to establish a mechanism to correlate the messages.
  E. Given delays of up to ten days, a polling strategy is more efficient than callback.
  B. The client needs to develop and deploy a Web service to accept callbacks.
  D. The client and the service need to establish a mechanism to correlate the messages.
