SOA Design & Architecture Lab Sample Questions:
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.)
Assuming that the Invoice service, InvProc service, and ProcInv service are part of the
same service inventory, what steps would be required to fully apply the Official Endpoint
pattern?
- A. Because Service Consumers A, B, and C are already carrying out their data access via
published contracts, they are not affected by the Official Endpoint pattern. Service
Consumer D needs to be redesigned to not access the shared accounting database
directly, but to perform its data access by interacting with the official invoice-related service.
The Service Abstraction principle can be further applied to hide the existence of the shared
accounting database and other implementation details from current and future service
consumers. - B. None of the above.
- C. One of the invoice-related services needs to be chosen as the official service providing
invoice data access capabilities. Service Consumers A, B, and C then need to be
redesigned to only access the chosen invoice-related service. Service Consumer D also
needs to be redesigned to not access the shared accounting database directly, but to also
perform its data access by interacting with the official invoice-related service. The Service
Abstraction principle can be further applied to hide the existence of the shared accounting
database and other implementation details from current and future service consumers. - D. One of the invoice-related services needs to be chosen as the official service providing
invoice data access capabilities. Service Consumers A, B, and C then need to be
redesigned to only access the chosen invoice-related service. Because Service Consumer
D does not rely on an invoice-related service, it is not affected by the Official Endpoint
pattern and can continue to access the accounting database directly. The Service
Abstraction principle can be further applied to hide the existence of the shared accounting
database and other implementation details from current and future service consumers.
Correct Answer: C 🗳️
Service A has become increasingly difficult to maintain. Its core service logic has become
bloated and convoluted because it has been updated numerous times during which
additional functionality was added to interact with the database and the legacy system and
to support interaction with Service Consumers A and B (via the two service contracts) as
well as interaction directly with Service Consumer C.
What steps can be taken to solve these problems and to prevent them from happening
again in the future?
- A. The Service Facade pattern can be applied to position a Facade component between
the core service logic and the implementation resources (the database and the legacy
system) and to also position a Facade component between the two service contracts and
Service Consumers A and - B. None of the above.
- C. The Service Faade pattern can be applied to position a Facade component between the
core service logic and the two service contracts. The Contract Centralization pattern can be
applied to limit access to Service A to one of its two published service contracts. The
Service Loose Coupling principle can be applied so that Service Consumer C does not
negatively couple itself directly to the core service logic of Service A . - D. The Official Endpoint pattern can be applied to limit access to Service A to one of its two
published service contracts. The Service Loose Coupling principle can be applied so that
Service Consumer C does not negatively couple itself directly to the core service logic of
Service A . B.
The Service Facade pattern can be applied to position a Facade component
between the core service logic and the implementation resources (the database and the
legacy system) and to position a faade component between the core service logic and the
two service contracts. The Contract Centralization pattern can be applied to limit access to
Service A to one of its two published service contracts. The Service Abstraction principle
can be applied to hide the implementation details of Service A from service consumers.
Correct Answer: D 🗳️
Service Consumer A sends a message with a business document to Service A (1), which
writes the business document to Database A (2). Service A then forwards the business
document to Service B (3), which writes the business document to Database B (4).
Service B then responds to Service A with a message containing a failure or success code
(5) after which Service A responds to Service Consumer A with a message containing a
failure or success code (6). Upon receiving the message, Service Consumer A updates a
log table in Database B (7). The log entry is comprised of the entire business document.
Database A is dedicated to the Service A service architecture and Database B is a shared
database.
You are told that the database updates performed by Service A and Service B must be
either both successful or they cannot happen at all. The database update performed by
Service Consumer A must happen after it is given the outcome of the database updates
performed by Service A and Service B . Given that Service Consumer A must also update
Database B as part of this service composition architecture, how is it possible to fulfill these
requirements?
- A. The Atomic Service Transaction pattern can be applied to encompass Service A,
Service B and Service Consumer A.
This will guarantee that all of the actions performed by the service composition participants will either be successful or will be rolled back if anyone
is not successful. - B. The State Repository pattern can be applied so that Service A writes the business
document data to a separate state database until it receives a response message from
Service B . If the response message contains a success code, Service A writes the
business document to Database A.
If the response contains a failure code, Service A
discards the data that was written to the state database. - C. The Service Data Replication pattern can be applied to Service Consumer A and
Service B so that separate dedicated databases can be established allowing Service
Consumer A to make updates independently of Service B . Service A is simply redesigned
to not write the business document to Database A until after it receives a message
containing a success code from Service B. - D. None of the above.
Correct Answer: D 🗳️
Service A is an entity service that provides a set of generic and reusable service
capabilities. In order to carry out the functionality of any one of its service capabilities,
Service A is required to compose Service B (1) and Service C (2) and Service A is required
to access Database A (3), Database B (4), and Database C (5). These three databases are
shared by other applications within the IT enterprise.
All of service capabilities provided by Service A are synchronous, which means that for
each request a service consumer makes. Service A is required to issue a response
message after all of the processing has completed.
Depending on the nature of the service consumer request, Service A may be required to
hold data it receives in memory until its underlying processing completes. This includes
data it may receive from either Service A or Service B or from any of the three shared
databases.
Service A is one of many entity services that reside in a highly normalized service
inventory. Because Service A provides agnostic logic, it is heavily reused and is currently
part of many service compositions.
You are told that Service A has recently become unstable and unreliable. The problem has
been traced to two issues with the current service architecture. First, Service B, which is
also an entity service, is being increasingly reused and has itself become unstable and
unreliable. When Service B fails, the failure is carried over to Service A . Secondly, shared
Database B has a complex data model. Some of the queries issued by Service A to shared
Database B can take a very long time to complete. What steps can be taken to solve these
problems without compromising the normalization of the service inventory?
- A. The Redundant Implementation pattern can be applied to Service B, thereby making
duplicate deployments of the service available. This way, when one implementation of
Service B is too busy, another implementation can be accessed by Service A instead. The
Service Data Replication pattern can be applied to establish a dedicated database that
contains a copy of the data from shared Database B that is required by Service A . The
replicated database is designed with an optimized data model in order to improve query
execution performance. - B. The Redundant Implementation pattern can be applied to Service B, thereby making
duplicate deployments of the service available. This way, when one implementation of
Service B is too busy, another implementation can be accessed by Service A instead. The
Service Data Replication pattern can be applied to establish a dedicated database that
contains an exact copy of the data from shared Database B that is required by Service A . - C. None of the above.
- D. The Redundant Implementation pattern can be applied to Service A, thereby making
duplicate deployments of the service available. This way, when one implementation of
Service A is too busy, another implementation can be accessed by service consumers
instead. The Service Data Replication pattern can be applied to establish a dedicated
database that contains an exact copy of the data from shared Database B that is required
by Service A .
