Question 1

Using WS-AtomicTransaction you wrap 3 SOAP-based Web services in a single transaction. When it is time to vote on the outcome of the transaction, 2 of the services vote to commit the changes made during the transaction, but a vote from the third service is not received. What will happen?

Accepted Answer

A)   The changes are committed because the transaction is considered successful as long as no Abort votes are received.
B)   The changes are rolled back because the transaction is considered unsuccessful when there is a missing vote.
C)   The changes are committed because the transaction is considered successful as long as one Commit vote is received.
D)   The changes are aborted because a transaction can only be considered successful when more than 2 Commit votes are received. B

Question 2

I would like to add two different WS-Policy definitions to my SOAP-based Web service and I would like to give the service consumer the choice to comply to either policy. How can I do this?

Accepted Answer

A)   Create a separate XML schema for each policy and attach both XML schemas to the service's WSDL definition.
B)   Create the two separate policies and group them in a policy alternative that is then associated with the service's WSDL definition.
C)   Communicate each policy through a separate WS-Addressing SOAP header and let the service consumer choose which header to use.
D)   You cannot do this. B

Question 3

Question 4

XSLT is a technology that is primarily used to address _____________________.

Accepted Answer

Question 5

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?

Accepted 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.

Question 6

Which of the following service designs are considered not supportive of service-orientation due to improper selection of technologies?  (Select all that apply.)

Accepted Answer

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.

Question 7

Which of the following statements is true?

Accepted Answer

A)   Individual service contracts do not need to be published for SOAP-based Web services. Instead, they use a uniform contract.
B)   Individual service contracts do not need to be published for REST services. Instead, they use a common uniform contract.
C)   Components provide published contracts, but when building services as components, components must use a uniform contract instead.
D)   None of these statements are true.

Question 9

Which of the following statements is true?

Accepted Answer

D)   REST services share a common uniform contract.

Question 12

Which of the following statements is true?

Accepted Answer

A)   A service enters the service provider role when it initiates contact with other services, including those that act as intermediaries.
B)   A service enters the service provider role when it initiates contact with intermediaries only.
C)   A service enters the service provider role when it is accessed by other service consumers, including intermediaries.
D)   A service enters the service provider role when it is accessed by intermediaries only.

Question 13

The amount of services participating in a service activity, the duration of the service activity, the amount of service activity instances that concurrently exist, and rules associated with the service activity are all examples of:

Accepted Answer

A)   design-time data that is defined via the WSDL data definition language
B)   runtime data that is expressed as part of a WSDL service operation definition
C)   state or context data that can be managed using WS-Coordination
D)   repository resource data that can be managed using WS-Policy via persistence in a database for long-term storage

Question 14

Data model transformation is a core service function that can be performed by proven technologies that have been around for years. Therefore, it is recommended that you look for opportunities to apply this technology wherever possible, especially in larger, more complex service compositions.

 B)False

Question 15
