Question 5

It is possible to have 3 SOAP-based Web services, each with a WSDL definition that has an operation named Update.

Accepted Answer

A) True 
 B)False

Question 6

An XML schema can be used to define XML documents that can be shared by components, SOAP-based Web services, and REST services.

Accepted Answer

A) True 
 B)False

Question 7

Identify what is wrong with this statement: "Component A invoked SOAP-based Web Service B, which invoked REST Service C."

Accepted Answer

A)  Components cannot invoke SOAP-based Web services. A SOAP-based Web service can only be invoked by another SOAP-based Web service. 
B)  SOAP-based Web services cannot invoke REST services. A REST service can only be invoked by another REST service. 
C)  Because they require different transport protocols, the same data cannot be sent from a component to a SOAP-based Web service and then to a REST service. 
D)  There is nothing wrong with this statement.

Question 8

Identify what is wrong with this statement: "SOAP-based Web services A and B are participating in a runtime transaction that is carried out as per the WS-AtomicTransaction standard. When a message sent by Service A is rejected by Service B due to a violation of a WS-Policy definition expressed as part of the Service B contract, Service A is forced to issue an Abort message, thereby requiring the transaction to be rolled back."

Accepted Answer

A)  WS-AtomicTransaction does not support the rollback of changes that occur during runtime transactions. 
B)  WS-Policy definitions are not expressed as part of the service contract. 
C)  SOAP-based Web services cannot have policies and cannot participate in runtime transactions because they are limited to the use of a uniform service contract. 
D)  There is nothing wrong with this statement.

Question 9

An intermediary can be an initial sender or an ultimate receiver.

Accepted Answer

A) True 
 B)False

Question 10

Which of the following statements is false?

Accepted Answer

A)  Services built as components can expose a non-industry-standard technical service contract. 
B)  Services built as components can be assembled into service compositions. 
C)  Services built as components always have a decoupled service contract that exists as a physically separate XML document. 
D)  Services cannot be built as components.

Question 11

Which of the following statements is true?

Accepted Answer

A)  WS-BusinessActivity is used for short-running, ACID-style transactions that can be rolled back to their original state. 
B)  WS-BusinessActivity is used for long-running transactions that are not expected to be rolled back to their original state. 
C)  WS-BusinessActivity provides an alternative to WS-Coordination. 
D)  None of these statements are true.

Question 12

Which of the following statements are false? (Select all that apply.)

Accepted Answer

A)  A service enters the service consumer role only when it initiates contact with other service consumers. 
B)  A service enters the service consumer role only when it accesses other services acting as intermediaries. 
C)  A service enters the service consumer role when it initiates contact with other services acting as service providers, including those also acting as intermediaries. 
D)  A service cannot enter the service consumer role.

Question 13

If Service B is invoked by Service A and then Service B invokes Service C and all of this happens as part of the same service activity, then Service B would be considered:

Accepted Answer

A)  an intermediary 
B)  a service agent 
C)  an ultimate receiver 
D)  an initial sender

Question 14

Which of the following statements makes sense?

Accepted Answer

A)  I designed a unique XML schema for each of my REST services so that the HTTP methods used by these services are consistently named. 
B)  My REST services are limited to the use of the GET HTTP method because only one XML schema was designed for all of them. In order to support additional HTTP methods, additional XML schemas will need to be designed due to the inherent dependency HTTP has on the XML Schema Definition Language. 
C)  I designed my REST services to share the same XML schema. 
D)  XML schemas cannot be used by REST services.

Question 15

To create REST services, you are required to deploy an enterprise service bus due to the need for inherent message routing functionality.

Accepted Answer

A) True 
 B)False

Question 16

A WS-Policy definition can be attached to different parts of a __________________ or to multiple __________________.

Accepted Answer

A)  service activity, service activities 
B)  service contract, service contracts 
C)  service model, service models 
D)  service line, service lines

Question 17

Which of the following statements is true?

Accepted Answer

A)  WSDL definitions can use XML schemas to define the types used by WSDL input and output messages. 
B)  WSDL definitions can use XML schemas to define the types used by WSDL input and output operations. 
C)  WSDL definitions can use XML schemas to define the types used to establish the location used by service consumers to access the WSDL definitions. 
D)  WSDL definitions cannot be used in conjunction with XML schemas.

Question 18

I would like to extend my WSDL definition to include a programmatically consumable statement that communicates that upon receiving a message the service will add an entry to an event log. Which technology should I use?

Accepted Answer

A)  Mashup 
B)  XSLT 
C)  REST 
D)  None of the above.

Question 19

Identify what is wrong with this statement: "If I have 4 SOAP-based Web services, I must have 4 WSDL definitions and 4 XML schemas."

Accepted Answer

A)  SOAP-based Web services don't use XML schemas for their WSDL definitions. 
B)  WSDL definitions can share the same XML schema and can also link to multiple XML schemas, so stating that 4 SOAP-based Web services must have 4 XML schemas is incorrect. 
C)  Each WSDL definition must have at least 2 XML schemas, so the correct amount of required XML schemas in this case is 8. 
D)  There is nothing wrong with this statement.

Question 20

WS-BPEL process definitions can be encapsulated by and exposed as SOAP-based Web services.

Accepted Answer

A) True 
 B)False
