NO.3 Which of the following statements is true?
A. The meet-in-the-middle delivery approach allows an on-going top-down analysis to occur while
services are designed and delivered. The only requirement is that delivered services eventually be
updated to be kept in alignment with the results of the top-down analysis.
B. The meet-in-the-middle delivery approach is essentially based on the bottom-up approach in that it
allows services to be delivered without up-front analysis. The only difference is that the
meet-in-the-middle approach advocates the use of object-orientation principles instead of
service-orientation principles.
C. The meet-in-the-middle delivery approach is essentially based on the top-down approach in that it
allows services to be delivered after the completion of the top-down analysis. The only difference is that
the meet-in-the-middle approach advocates the use of people that act as mediators who ensure that
business analysts and technology architects can collaborate harmoniously.
D. None of these statements are true.

point-to-point integration channels between legacy systems.
C. The bottom-up approach is focused primarily on maximizing service reuse. Therefore, special attention
is paid to the documentation of service profile information that is used to create complete service catalog
entries.

NO.1 Your developer is asked to build a Timesheet service that is able to receive timesheet submissions for
an internal payroll system. Service consumers need to be able to send this service request message
based on a root "employeeHours" element within the SOAP message body. The "employeeHourse"
element will contain "ernpID" and "hours" child elements. Furthermore, the service needs to return a
message based on a "response" element that contains "empID" and "status" child elements.
Your developer comes to you with the following WSDL definition: The only revision you suggest is that the
value of the "style" attribute of the "soap: binding" element be changed to "document" instead of "rpc".
Why?
A. With a value of "rpc", the root element within the SOAP message body will have the name of the
operation, and therefore cannot be named "employeeHours" as indicated by the requirements.
B. With a value of "rpc", the root element within the SOAP message body is unable to be part of an
operation that contains both "input" and "output" elements.
C. The value of "rpc" is not a valid value for the "style" attribute.
D. None of the above.

NO.2 Your company has developed a PO service that allows customers to submit purchase order documents.
The message sent by a customer must be based on a predefined "purchaseOrder" element and the
message received by the customer is based on a "messageAcknowledgement" element. These two
elements are defined in the following two separate XML Schema definitions: The "purchaseOrder.xsd"
schema:
Note that these two schemas have different namespaces. That is because the "purchaseOrder.xsd"
schema is specific to purchase order-related functions, while the "ack.xsd" schema is more generic and
used for a variety of different purposes.

NO.1 The Client and Vendor services are agnostic services that are both currently part of multiple service
compositions. As a result, these services are sometimes subjected to concurrent access by multiple
service consumers.
The Client service is an entity service that primarily provides data access logic to a client database but
also provides some calculation logic associated with determining a client's credit rating. The Vendor
service is also an entity service that provides some data access logic but can also generate various
dynamic reports.
After reviewing historical statistics about the runtime activity of the two services, it was discovered that the
majority of concurrent runtime access is related to the processing of business rules. With the Client
service, it is the calculation logic that is frequently required and with the Vendor service it is the dynamic
reporting logic that needs to be accessed separately from the actual report generation.
Currently, due to the increasing amount of concurrent access by service consumers, the runtime
performance of both the Client and Vendor services has worsened and has therefore reduced their
effectiveness as service composition members. What steps can be taken to solve this problem without
introducing new services?
A.The Rules Centralization pattern can be applied by extracting the business rule logic from the Client
and Vendor services and placing it into a new Rules service. This will naturally improve the runtime
performance of the Client and Vendor services because they will no longer be subjected to the high
concurrent access of service consumers that require access to the business rules logic.
B.The Redundant Implementation pattern can be applied to the Client and Vendor services, thereby
establishing duplicate implementations that can be accessed when a service reaches its runtime usage
threshold. The Intermediate Routing pattern can be further applied to provide load balancing logic that
can, at runtime, determine which of the redundant service implementations is the least busy for a given
service consumer request.
C.The Rules Centralization pattern can be applied together with the Redundant Implementation pattern to
establish a scalable Rules service that is redundantly implemented and therefore capable of supporting
high concurrent access from many service consumers. The Service Abstraction principle can be further
applied to hide the implementation details of the Rules service.
D.None of the above.
Answer:B

NO.2 Service A is an entity service with a functional context dedicated to invoice-related processing. Service
B is a utility service that provides generic data access to a database.
In this service composition architecture, Service Consumer A sends a SOAP message containing an
invoice XML document to Service A (1). Service A then sends the invoice XML document to Service B (2),
which then writes the invoice document to a database.
The data model used by Service Consumer A to represent the invoice document is based on XML
Schema A. The service contract of Service A is designed to accept invoice documents based on XML
Schema B. The service contract for Service B is designed to accept invoice documents based on XML
Schema A. The database to which Service B needs to write the invoice record only accepts entire
business documents in Comma Separated Value (CSV) format.
Due to the incompatibility of the XML schemas used by the services, the sending of the invoice document
from Service Consumer A through to Service B cannot be accomplished using the services as they
currently exist. Assuming that the Contract Centralization pattern is being applied and that the Logic
Centralization is not being applied, what steps can be taken to enable the sending of the invoice
document from Service Consumer A to the database without adding logic that will increase the runtime
performance requirements of the service composition?
A.Service Consumer A can be redesigned to use XML Schema B so that the SOAP message it sends is
compliant with the service contract of Service A. The Data Model Transformation pattern can then be
applied to transform the SOAP message sent by Service A so that it conforms to the XML Schema A used
by Service B. The Standardized Service Contract principle must then be applied to Service B and Service
Consumer A so that the invoice XML document is optimized to avoid unnecessary validation.
B.The service composition can be redesigned so that Service Consumer A sends the invoice document
directly to Service B. Because Service Consumer A and Service B use XML Schema A, the need for
transformation logic is avoided. This naturally applies the Service Loose Coupling principle because
Service Consumer A is not required to send the invoice document in a format that is compliant with the
database used by Service B.
C.Service Consumer A can be redesigned to write the invoice document directly to the database. This
reduces performance requirements by avoiding the involvement of Service A and Service B. It further
supports the application of the Service Abstraction principle by ensuring that Service Consumer A hides
the details of the data access logic required to write to the database.
D.None of the above.

NO.3 Service A is an entity service with a functional context dedicated to invoice-related processing. Service
B is a utility service that provides generic data access to a database.
In this service composition architecture, Service Consumer A sends a SOAP message containing an
invoice XML document to Service A (1). Service A then sends the invoice XML document to Service B (2),
which then writes the invoice document to a database.
The data model used by Service Consumer A to represent the invoice document is based on XML
Schema A. The service contract of Service A is designed to accept invoice documents based on XML
Schema B. The service contract for Service B is designed to accept invoice documents based on XML
Schema A. The database to which Service B needs to write the invoice record only accepts entire
business documents in Comma Separated Value (CSV) format.
Due to the incompatibility of XML schemas used by the services, the sending of the invoice document
from Service Consumer A through to Service B cannot be accomplished using the services as they
currently exist. Assuming that the Contract Centralization and Logic Centralization patterns are being
applied, what steps can be taken to enable the sending of the invoice document from Service Consumer A
to the database without adding logic that will increase the runtime performance of the service
composition?
A.The Data Model Transformation pattern can be applied so that the invoice document sent by Service
Consumer A is transformed into an invoice document that is compliant with the XML Schema B used by
Service A. The Data Model Transformation pattern can be applied again to ensure that the invoice
document sent by Service A is compliant with XML Schema A used by Service B.
B.The service composition can be redesigned so that Service Consumer A sends the invoice document
directly to Service B. Because Service Consumer A and Service B use XML Schema A, the need for
transformation logic is avoided. This naturally applies the Service Loose Coupling principle because
Service Consumer A is not required to send the invoice document in a format that is compliant with the
database used by Service B.
C.The Standardized Service Contract principle can be applied to the service contract of Service A so that
it is redesigned to use XML Schema A. This would make it capable of receiving the invoice document from
Service Consumer A and sending the invoice document to Service B without the need to further apply the
Data Model Transformation pattern.
D.None of the above.
