You are told that in this service composition architecture, all four services are exchanging
invoice-related data in an XML format. The services in Service Inventory A are
standardized to use a specific XML schema for invoice data. Design standards were not
applied to the service contracts used in Service Inventory B, which means that each
service uses a different XML schema for the same kind of data. Database A and Database
B can only accept data in the Comma Separated Value (CSV) format and therefore cannot
accept XML formatted data. What steps can be taken to enable the planned data exchange
between these four services?

정답: C
Service Consumer A sends a message to Service A.
There are currently three duplicate implementations of Service A (Implementation 1, Implementation 2, Implementation 3).
The message sent by Service Consumer A is intercepted by Service Agent A (1), which
determines at runtime which implementation of Service A to forward the message to.
All three implementations of Service A reside on the same physical server.
You are told that despite the fact that duplicate implementations of Service A exist,
performance is still poor at times. Also, you are informed that a new service capability will
soon need to be added to Service A that will introduce functionality that will require access
to a shared database that is used by many other clients and applications in the IT
enterprise. This is expected to add further performance demands on Service A . How can
this service architecture be changed to improve performance in preparation for the addition
of the new service capability?

정답: A
Our service inventory contains the following three services that provide invoice-related data
access capabilities: Invoice, InvProc, and Proclnv. These services were created at different
times by different project teams and were not required to comply to any design standards.
Therefore each of these services has a different data model for representing invoice data.
Currently each of these three services has one service consumer: Service Consumer A
accesses the Invoice service(1). Service Consumer B (2) accesses the InvProc service,
and Service Consumer C (3) accesses the Proclnv service. Each service consumer
invokes a data access capability of an invoice-related service, requiring that service to
interact with the shared accounting database that is used by all invoice-related services (4,
5, 6).
Additionally, Service Consumer D was designed to access invoice data from the shared
accounting database directly (7). (Within the context of this architecture. Service Consumer
D is labeled as a service consumer because it is accessing a resource that is related to the
illustrated service architectures.)
A project team recently proclaimed that it has successfully applied the Contract
Centralization pattern to the service inventory in which the Invoice service, InvProc service,
and ProcInv service reside. Upon reviewing the previously described architecture you have
doubts that this is true. After voicing your doubts to a manager, you are asked to provide
specific evidence as to why the Contract Centralization is not currently fully applied. Which
of the following statements provides this evidence?

정답: A
You are an architect with a project team building services for Service Inventory A . You are
told that no SLAs for Service B and Service C are available. You cannot determine how
available these services will be, but it has been confirmed that both of these services
support atomic transactions and the issuance of positive and negative acknowledgements.
However, you also find out that the services in Service Inventory B use different data
models than the services in Service Inventory A.
Furthermore, recent testing results have shown that the performance of Service D is steady and reliable. However, Service D uses a
different transport protocol than the services in Service Inventory A.
The response time of Service A is not a primary concern, but Service Consumer A does need to be able to issue
request messages to Service A 24 hours a day without disruption. What steps can be taken
to fulfill these requirements?
