B. participating services need to capture a snapshot of current data prior to making changes to it B.
a transaction management system that coordinates the actions of participating services

C. transaction participants must be able to commit changes or rollback uncommitted
changes

A. True

B. False

A. The Contract Centralization pattern can impose performance overhead and requires the
use of design standards.

B. The Contract Centralization pattern positions the service contract as the official entry
point into the service logic.

C. The application of the Contract Centralization pattern enables access to underlying
service resources through the use of secondary or unofficial technical contracts.

D. The Decoupled Contract pattern supports the application of the Contract Centralization
pattern.

A. Multiple technical service contracts can make reference to a single schema.

B. Schemas can be designed and implemented independently from the service capabilities
that utilize them.

C. Services in the same service inventory cannot share the same schemas.

D. Up-front analysis effort is required to establish a schema layer independent of and in
support of the service layer.

A. Changes to a shared data model can affect all services that rely upon it, which in turn,
can affect all service consumers that have formed dependencies on the corresponding
service contracts.

B. None of the above.

C. Changes to a shared policy definition can affect all services that rely upon it, which in
turn, can affect all service consumers that have formed dependencies on the
corresponding service contracts.

D. Changes to a shared database can affect all services that rely upon it, which in turn, can
affect all service consumers that have formed dependencies on the corresponding service
contracts.

A. True

B. False

A. common routing logic being physically centralized into a single service

B. common routing logic being removed from service logic and placed into service agents

C. common routing logic being physically centralized into a single service composition

D. common routing logic being removed from service agents and placed into a database

A. True

B. False

A. True

B. False

A. The Compensating Service Transaction pattern is one of the core patterns that comprise
the Enterprise Service Bus compound pattern.

B. A compensating service transaction must be designed independently and without
knowledge of the technical service contracts belonging to the composition members.

C. The Compensating Service Transaction pattern is often applied by calling one or more
"undo" operations provided as service capabilities of the services participating in a
composition.

D. Compensating logic is generally expressed in its own process definition and separated
from the overall service composition logic.
