Which of the following statement is true for the Web service client implementation to accomplish the booking process requirement?
A. Enable WS-Coordination only for the 3 Web services
B. Enable WS-Atomic Transaction only for the 3 Web services
C. Create a global transaction using Java Transaction API (JTA) User Transaction interface
D. Create a global transaction using Java Transaction API (JTA) User Transaction interface and enable WS-Atomic Transaction for the 3 Web services
A bank would like to design a JAX-WS Web service to transfer funds. The server will be deployed to IBM Web Sphere Application Server V7.0.Two key requirements are to ensure:
1) the request is only sent once 2) cross vendor interoperability
What is the best way to accomplish this?
A. Use WS-Security
B. Use WS-Atomic Transaction
C. Use WS-Reliable Messaging
D. Add a handler to implement the duplication detection logic
E. Implement application code in the Web service to detect duplication
An online retailer would like to expand the supply chain Web service application by adding new third party suppliers. Some of the key non-functional requirements include: support for vendor interoperability, loose coupling, long running processes, and to coordinate the order fulfillment across multiple suppliers. The application logic needs to be able to adjust the business processes to accommodate the success or failure of downstream suppliers being able to satisfy the request.
Which of the following quality of service standards should be used for the Web services?
A. WS-Activity Session
B. WS-Business Activity
C. WS-Reliable Messaging
D. WS-Atomic Transaction
E. WS-Business Transaction
A developer is creating a JAX-WS Web service. The Web service will be used to sendcheque image file
from the provider to the requestor. Given the following extract:
@MTOM(enabled=true, threshold=50)
@Web Service(name="Image Service",
target Namespace="http://com.test.ImageService")
public class Image Provider {
What does the threshold parameter indicate?
A. The minimum number of attachments that can be sent in the message
B. The maximum number of attachments that can be sent in the message
C. The maximum size in bytes for each attachment to be sent using MTOM.
D. The minimum size in bytes for each attachment before MTOM is used. Smaller attachments will use base64 inline encoding.
E. The maximum size in bytes for each attachment before MTOM streams to disk. Smaller attachments will keep the attachment in-memory.
A developer is building a JAX-WS Web service to be deployed on IBM Web Sphere Application Server V7.0. The service consumers are financial institutions with client applications using Microsoft .NET V3.5. The service will be used to retrieve image files and send them to the financial institutions.
What is the recommended approach to send the image files?
A. SOAP with Attachments
B. Direct Internet Message Encapsulation (DIME)
C. Message Transmission Optimization Mechanism (MTOM)
D. Message Handlers and the SOAP with Attachments API for Java (SAAJ)
Which of the following options for sending binary data are compliant to either WS-I Basic Profile (BP) V1.1 or V1.2?
A. SOAP with Attachments
B. Base64 encode the data inline
C. Direct Internet Message Encapsulation (DIME)
D. Message Transmission Optimization Mechanism (MTOM) / XML-Binary Optimized Packaging (XOP)
Which of the following are TRUE statements about the WS-I Basic Security Profile (BSP)?
A. BSP focuses on both SOAP-level constructs as well as TLS and SSL
B. BSP only focuses on SOAP-level constructs and does not reference TLS and SSL
C. BSP V1.0 focuses on WS-Security features while BSP V1.1 focuses on adding in other standards which use WS-Security such as WS-Secure Conversation and WS-Trust
D. BSP V1.0 focuses on WS-Security V1.0 features while BSP V1.1 focuses on WS- Security V1.1 features such as encrypted headers, signature confirmation, and thumbprint references
E. BSP V1.0 focuses on the following binary security tokens: Username Token, X.509 Certificate Token, and REL Token. BSP V1.1 adds support for Kerberos Token and SAML Token (as well as the prior tokens in BSP V1.0)
Select the scenario where the specification WS-Make Connection should be used.
A. To return responses back on a separate connection in arequest and response flow. Forexample, enabling WS-Addressing to specify a new address to deliver a response.
B. To establish a connection for out-of-band communication with 3rd endpoint. For example, in using WS-Secure Conversation with another business endpoint, a token can be obtained from a 3rd party provider.
C. To tunnel through a firewall and establish a back channel for messages to be sent to a previously unaddressable endpoint. For example, with WS- ReliableMessagingreestablishing a connection through a firewall for acknowledgements.
D. To create a separate connection to an endpoint to gain metadata about an endpoint prior to the initial request. For example, creating a connection to a separate endpoint to retrieve WSPolicy information about how to establish connectivity to a web services endpoint.
Which of the following standards does the WS-Organization recommend for Web services according to WS-I Basic Profile (BP)1.1?
A. WSDL 1.1, SOAP 1.1
B. WSDL 1.1, SOAP 1.1, MTOM
C. WSDL 1.1, SOAP 1.1, SOAP 1.2
D. WSDL 1.1, SOAP 1.1, SOAP 1.2, MTOM
E. WSDL 1.1, SOAP 1.1, SOAP with Attachments
According to WS-I Basic Profile (BP), which of the following encodings should be used to ensure interoperability?
A. rpc/literal
B. rpc/encoded
C. doc/literal
D. doc/encoded
