ITPEC IP October 2023 Question 96
ITPEC IP October 2023 — Question 96 of 100
SOA increases flexibility by constructing systems from reusable, loosely coupled services with defined interfaces. Services can be combined, replaced, or reused in different business processes with less dependence on internal implementations. This supports faster adaptation when requirements or participating systems change.
Answer (d)
Why not others:
- (a) service calls and integration do not inherently improve processing speed
- (b) SOA still requires separately designed authentication, authorization, transport, and service security
- (c) users still need appropriate education and operational guidance
Key rule: SOA's main architectural benefit is composability and change flexibility, not automatic performance, security, or removal of training needs.
