Explanation

Option D is correct because SOA success depends on consistent, organization-wide application of service-orientation principles - reusability, loose coupling, abstraction, composability, etc. - applied as a sustained strategic priority, not a one-off project. Without consistency across all services and teams, the inventory becomes fragmented and the core benefits (interoperability, reuse) never materialize.

Why the distractors fail:

• A - "Extending existing [legacy applications]" signals building on legacy structures rather than genuinely transforming toward service-orientation; this entrenches old boundaries and technical debt.
• B - Using legacy application boundaries as service boundaries is a classic anti-pattern; those boundaries reflect old technology/organizational silos, not natural business domains, so services inherit the wrong granularity and coupling.
• C - This is the clearest red flag: SOA is explicitly a long-term strategic investment, not a tactical/short-term one. Any strategy describing service-oriented computing as "tactical" fundamentally misunderstands it.

Memory tip: Remember "SOA = Strategic, not Tactical." On exam questions, any option framing SOA as short-term or tactical is wrong. The correct strategy always emphasizes consistent principles applied organization-wide over time - look for those two signals together.
