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.
An enterprise has a requirement to create a Web service to accept purchase orders. The order data contains some authorization information that is specific to each order (such as, who can access which parts of the order).
Keeping in mind future enhancements in types of orders that the enterprise needs to accept, which two design solutions provide the most flexibility? (Choose two .)
A. a Web service interface with one method per accepted XML document type for a purchase order
B. a procedure-style Web service method that lists all data elements and all possible access control options.
C. a document-style Web service method that accepts all types of XML documents representing purchase orders.
D. a Web service interface with one method for each combination of data elements and the access control options.
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.
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 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 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.
Which two statements are true about creating a SOAP message with an attachment? (Choose two.)
A. Binary attachments make SOAP incompatible with HTTP.
B. A SOAP Message package must specify Content-Type as multipart/related.
C. If one or more attachments are XML, they must be in the body of the SOAP message.
D. MIME attachments referenced inside the SOAP body must use SOAP references.
E. MIME provides a method to encode attachments in XML making them compatible with SOAP.
A Java EE 5 application contains business logic composed of EJB3 beans. All current clients are Java applications accessing the business logic using RMI. Some clients are remote (running in different JVMs) and some are local (running in the same JVM). Which two occur if EJB components are exposed as Web services? (Choose two.)
A. New applications can use published interfaces to access existing applications.
B. Current local clients must access the Web services in the application as an URL.
C. WSDL documents define common types for all clients.
D. Current remote clients must switch from RMI to Web service access.
E. Delivery of messages is guaranteed for local clients.
A student developer has created a new library of math functions to share with friends in a linear algebra class. The developer is having difficulty getting people to come over to the dorm to see the new code library, so he decides to deploy it as a Web service so that everyone can enjoy the features via the Internet. One of the functions has this WSDL definition:
Which two statements are true about this Web service? (Choose two.)
A. This is an asynchronous receive.
B. This is an asynchronous send.
C. The client must use SOAPFaultException to display any errors.
D. It must send a SOAP fault back to the sender.
E. It must NOT send a SOAP fault back to the sender.
A company has contracted a developer to create their new accounting system. The system the developer will replace runs a monolithic web application using one web server and one database server. Technical requirements state the developer must write the business logic in Java, deploy to the application server and push the presentation logic onto the web servers. What are three characteristics of services in the proposed Service Oriented Architecture? (Choose three.)
A. Services are coarse grained.
B. Services are finely grained.
C. Services are loosely coupled.
D. Services are tightly coupled.
E. Clients must be implemented in the Java technology.
F. Services are platform agnostic, network-addressable web APIs.
