NO.2 Two service delivery projects are being carried out concurrently. Each project has its own project team.
Even though both projects are delivering services for the same service inventory, each project team is
given complete independence as to how services are designed and developed and what design
standards are to be used. Which of the following statements describes a likely consequence of this
approach.?
A. The service inventory will be comprised of services that comply to different design standards and these
services will therefore not be compatible or interoperable.
B. Services with redundant and overlapping logic may be delivered because no effort was made to
coordinate the delivery of the services between the two projects.
C. One project team may decide to follow a top-down delivery approach, whereas the other project team
may follow a bottom-up delivery approach.
D. All of the above.
Answer: D

A. We delivered the project using a meet-in-the-middle approach, which allowed us to start building
services before completing our top-down analysis.
B. We delivered the project using a meet-in-the-middle approach, which allowed us to complete our
service inventory blueprint before delivering our services.
C. We delivered the project using a meet-in-the-middle approach, which allowed us to bypass up-front
analysis altogether so that we could build our services in the shortest possible timeframe.
D. None of these statements make sense.

NO.4 Which of the following statements is false?
A. With the bottom-up approach, services are built on an "as need" basis and are modeled to encapsulate
application logic to best serve the immediate requirements of the solution.
B. The bottom-up approach is often motivated by integration needs that may require establishing
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.5 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.

NO.4 Service A and Service B belong to Organization A and Service C belongs to Organization B. Service A
sends confidential messages to Service B, which forwards these messages to Service
C. The message sent to Service C is intercepted by a load balancing service agent that determines which
instance of Service C to route the message to. This entire message path needs to be encrypted in order
to ensure message confidentiality from when the message is first sent by Service A until it is received by
an instance of Service C. Organization A doesn't trust any intermediaries that may exist in between
Service B and Service C and also doesn't want to share any keys with Organization B. Furthermore, there
is a requirement to minimize any adverse effects on performance. Which of the following approaches
fulfills these requirements?
A. Use message-layer security by adding symmetric encryption between Services A, B and C. This
way,message content is not available to any intermediaries between Services B and C.
B. Because Service A and Service B exist within the same organizational boundary, use transport-layer
security to provide message confidentiality. Use message-layer security via asymmetric encryption
between Service B and Service C.
C. Use transport-layer security between Service B and Service C and use message-layer security via
asymmetric encryptionbetween Service A and Service B. This way. all the services are secured while at
the same time minimizing the performance degradation between Service B and Service C.
D. None of the above.

necessary. Which of the following answers explains this response?
A. The certificate authority needs to issue a new public key instead.
B. The certificate authority requires that the existing public key needs to be changed within the existing
certificate.

NO.10 A task service needs to access three entity services as part of a service composition. The task service
needs to authenticate itself every time it accesses one of the three entity services. Because the task
service must authenticate itself three times to complete its task, the current service composition design is
considered inefficient. How can it be improved while continuing to fulfill the authentication requirements?
A. Increase the network bandwidth between the task service and the entity services.
B. Use a single sign-on mechanism.
C. Remove the authentication requirements within the service composition, thereby reducing the
message size and making communication faster.
D. None of the above

NO.11 Service A sends a message to Service B which reads the values in the message header to determine
whether to forward the message to Service C or Service D. Because of recent attacks on Services C and
D, it has been decided to protect the body content of messages using some form of encryption. However,
certain restrictions within the design of Service B will not permit it to be changed to support the encryption
and decryption of messages. Only Services A, C and D can support message encryption and decryption.
Which of the following approaches fulfill these security requirements without changing the role of Service
B?
A. Transport-layer security is implemented between all services.
B. Message-layer security is implemented between all services.
C. Service B is removed. Instead, the routing logic is added to Service A.
D. None of the above
Answer: B

NO.12 As a requirement for accessing Service B, Service A needs to encrypt its request message. Service B
decrypts the message, makes some changes, encrypts the message, and then forwards it to Service C.
However, the message does not make it to Service C. Instead, a runtime error is raised by a service agent
that does not support encryption. This service agent only requires access to the message header in order
to route the message to the appropriate instance of Service C. It is therefore decided that the header part
of the message will not be encrypted. Which of the following can be used to address this requirement?
A. certificate authority
B. SAML
C. non-repudiation
D. None of the above
Answer: D

NO.1 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.

NO.2 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.

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 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.1 The owner of a service inventory reports that the public key related to a certain private key has been
lost. There is a concern that this was the result of a security breach. A security specialist recommends
contacting the certificate authority in order to add the corresponding certificate to the certificate authority's
Certificate Revocation List (CRL). However, the certificate authority responds by indicating that this is not
necessary. Which of the following answers explains this response?
A. The certificate authority needs to issue a new public key instead.
B. The certificate authority requires that the existing public key needs to be changed within the existing
certificate.
C. Public keys cannot get lost because they are alreadypublicallyavailable.
D. None of the above

NO.3 Service A sends a message to Service B which reads the values in the message header to determine
whether to forward the message to Service C or Service D. Because of recent attacks on Services C and
D, it has been decided to protect the body content of messages using some form of encryption. However,
certain restrictions within the design of Service B will not permit it to be changed to support the encryption
and decryption of messages. Only Services A, C and D can support message encryption and decryption.
Which of the following approaches fulfill these security requirements without changing the role of Service
B?
A. Transport-layer security is implemented between all services.
B. Message-layer security is implemented between all services.
C. Service B is removed. Instead, the routing logic is added to Service A.
D. None of the above

NO.4 As a requirement for accessing Service B, Service A needs to encrypt its request message. Service B
decrypts the message, makes some changes, encrypts the message, and then forwards it to Service C.
However, the message does not make it to Service C. Instead, a runtime error is raised by a service agent
that does not support encryption. This service agent only requires access to the message header in order
to route the message to the appropriate instance of Service C. It is therefore decided that the header part
of the message will not be encrypted. Which of the following can be used to address this requirement?
A. certificate authority
B. SAML
C. non-repudiation
D. None of the above
Answer: D

NO.5 A task service needs to access three entity services as part of a service composition. The task service
needs to authenticate itself every time it accesses one of the three entity services. Because the task
service must authenticate itself three times to complete its task, the current service composition design is
considered inefficient. How can it be improved while continuing to fulfill the authentication requirements?
A. Increase the network bandwidth between the task service and the entity services.
B. Use a single sign-on mechanism.
C. Remove the authentication requirements within the service composition, thereby reducing the
message size and making communication faster.
D. None of the above

NO.9 Service A and Service B belong to Organization A and Service C belongs to Organization B. Service A
sends confidential messages to Service B, which forwards these messages to Service
C. The message sent to Service C is intercepted by a load balancing service agent that determines which
instance of Service C to route the message to. This entire message path needs to be encrypted in order
to ensure message confidentiality from when the message is first sent by Service A until it is received by
an instance of Service C. Organization A doesn't trust any intermediaries that may exist in between
Service B and Service C and also doesn't want to share any keys with Organization B. Furthermore, there
is a requirement to minimize any adverse effects on performance. Which of the following approaches
fulfills these requirements?
A. Use message-layer security by adding symmetric encryption between Services A, B and C. This
way,message content is not available to any intermediaries between Services B and C.
B. Because Service A and Service B exist within the same organizational boundary, use transport-layer
security to provide message confidentiality. Use message-layer security via asymmetric encryption
between Service B and Service C.
C. Use transport-layer security between Service B and Service C and use message-layer security via
asymmetric encryptionbetween Service A and Service B. This way. all the services are secured while at
the same time minimizing the performance degradation between Service B and Service C.
D. None of the above.
