최신 S90.08 무료덤프 - SOA Advanced SOA Design & Architecture

A. True

B. False

A. When business process logic is physically distributed across independent service
implementations, it can be difficult to extend and evolve due to its decentralized nature.

B. Grouping non-agnostic business logic together with agnostic business logic hinders the
governance of the non-agnostic logic and the reuse of the agnostic logic.

C. Bundling both messaging and validation logic into the same service eventually results in
the creation of redundant logic across multiple services, thereby causing performance
challenges.

D. The same business rules may exist within different business-centric services, leading to
redundancy issues and governance problems due to the challenge of maintaining
consistent rule logic within multiple services as rules changes over time.

A. Service agents are common in orchestration environments but not within enterprise
service bus environments.

B. The overuse of service agents can lead to dependencies on proprietary vendor
platforms.

C. The use of service agents is limited to the service architecture.

D. None of these statements are true.

A. no coupling of the service consumer to the legacy system encapsulated by the wrapper
service D.
no coupling of the service logic to the service contract

B. no coupling of the wrapper service logic to the legacy system

C. no coupling of the wrapper service logic to the service contract

A. True

B. False

A. WS-Policy

B. WSDL

C. XHTML

D. None of the above.

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

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

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

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

A. core service logic, legacy system

B. core service logic, resource

C. All of the above.

D. core service logic, database

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

B. 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.

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

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

A. The need to perform content-based routing based upon metadata found in the message
header.

B. The need to increase the autonomy of a service due to its reliance on a shared data
source.

C. The need for load-balanced access to a redundantly deployed service.

D. The need to provide pre-defined compensating logic for when an atomic service transaction fails.
