The Service-Oriented Integration (SOI) architecture can be deployed in a variety of ways. One
deployment option is a hierarchical deployment, where each division within the enterprise can
deploy the layers of the SOI architecture by using their chosen hardware and software platforms.
A separate enterprise-wide deployment of the upper layers of the architecture is used to provide
cross-divisional integration. Which statements are true for this type of hierarchical deployment of
SOI?
A.
Hierarchical deployment of the SOI architecture is the recommended deployment whenever an
enterprise has two or more business divisions.
B.
Hierarchical deployment of the SOI architecture is an anti-pattern and should be avoided du-the
additional costs associated with supporting multiple hardware and software platforms.
C.
Hierarchical deployment of the SOI architecture is a transitional phase moving toward a peerpeer deployment where the enterprise-wide deployment of the upper layers is eliminated.
D.
Hierarchical deployment of the SOI architecture supports aquestions because each aquestions
can be treated as a new division with its own chosen hardware and software platforms.
E.
Because each division is allowed to select the hardware and software platform, industry
standards become more important to ensure interoperability between the divisions and the
enterprise-wide upper layer.
F.
Because each division is allowed to select the hardware and software platform, platform
vendors will have the complete for business, which will reduce the costs of hardware and software,
thus reducing the cost of technical deployment versus a shared deployment.
Explanation:
D: This type of deployment easily supports acquisitions since a new acquisition can
be treated as simply another portfolio.
E (not F): The primary disadvantage of a hierarchical deployment is the increased cost and
complexity of supporting more hardware and software. Adherence to standards to
support interoperability is also more important in a hierarchical deployment since the
various portfolios may select different products
