Which statement best describes the use of point-to-point integrations within a Service-Oriented
Integration (SOI) architecture?
A.
point-to-point integrations using web services are an Integral part of SOI and should be used
extensively.
B.
Only web service-based point-to-point integrations are allowed (but discouraged).
C.
Point-to-point integrations should be avoided but are allowed as exceptions when requirements
can be met only by point-to-point integration.
D.
Point-to-point integrations are brittle and expensive to maintain and therefore should never be
used.
Explanation:
Avoid Point-to-Point Integrations. Point-to-point integrations are brittle, inflexible,
and expensive to maintain. There are cases where point-to-point integrations
are required but these should be handled as exception cases. Example exceptions include
performance requirements that can only be met using point-to-point connections and when large
amounts of data must be moved.
