A. event logging

B. message routing

C. error logging

D. complex Web service composition

A. logically centralizes task services into an enterprise service bus

B. physically centralizes task services into an enterprise service bus

C. physically centralizes business process logic into a single location

D. logically centralizes business process logic into a separate service layer

A. utility service

B. task service

C. entity service

D. hybrid service

A. a service consumer, acting as a subscriber, can selectively subscribe to specific events

B. an intermediate event management program enters the role of subscriber when
accepting event subscriptions

C. a service, acting as a publisher, issues event notification messages to an event
management program that is responsible for broadcasting the messages

D. upon receiving a message associated with an event that a service consumer subscribed
to, the service consumer enters the publisher role

A. alternative compensating logic is executed to undo changes that may have been
committed by the services participating in a transaction

B. services be designed to be aware of all the other services that have also registered as
participants in the same transaction in order to exchange success or failure messages with them

C. None of the above.

D. a service participating in a transaction either commit or rollback changes in response to
the success or failure of the transaction

A. The Decoupled Contract pattern results in the separation of the service contract from the
service implementation, allowing the service contract to be independently designed and
governed.

B. The application of the Policy Centralization pattern eliminates redundancy and
inconsistency by creating a single, master policy bound to the WSDL definition of every
service in a service inventory.

C. The Schema Centralization pattern supports the creation of independent data models
that define data transmitted in SOAP messages.

D. The Legacy Wrapper pattern can be used to expose a legacy system as a SOAP-based
Web service with a standardized technical service contract.

A. A compensating service transaction is only used in situations where the rollback of
changes across services needs to be guaranteed.

B. A compensating service transaction always exists within the scope of an atomic service
transaction.

C. The application of the Compensating Service Transaction pattern relies heavily upon an
underlying database that supports the rollback of changes.

D. None of these statements are true.

A. All of these statements are true.

B. A compensating service transaction can be more efficient than an atomic service
transaction with regards to runtime memory consumption.

C. Compensating service transactions are suitable for long-running service activities.

D. Upon detection of an exception, pre-defined compensation logic can be executed to
handle the exception.

A. The application of the Intermediate Routing pattern tends to improve runtime
performance when compared to an approach whereby routing logic is embedded within
individual services.

B. The application of the Intermediate Routing pattern is suitable for handling pre-
determined message paths with fixed routing requirements that cannot be changed at
runtime.

C. None of these statements are true.

D. The application of the Intermediate Routing pattern is suitable for handling message
routing requirements that are dynamic in nature and difficult to anticipate in advance.

A. False

B. True
