Which of the following is an expected result of successfully adopting SOA?

Question

Options

• AA natural increase in runtime performance that you will gain as a result of the fact that service
• BThe fact that the existing IT organizational structure will not have to change because of how well a
• DThe strategic (long-term) target state that is attainable when many of the services delivered are

• A
  12% (4)
• B
  6% (2)
• D
  82% (28)

Explanation

Adopting SOA is fundamentally a strategic, long-term initiative. Option D is correct because SOA's recognized payoff is a future-state architecture where reusable, interoperable services enable business agility, reduced duplication, and accelerated delivery - benefits that accumulate over time as the service portfolio matures, not overnight.

Why A is wrong: SOA introduces overhead (network hops, serialization, service orchestration), so runtime performance often decreases initially or stays neutral. Performance gains are not a natural byproduct of adopting SOA.

Why B is wrong: SOA almost always demands organizational change - teams must shift toward service ownership, governance models, and cross-functional collaboration. The idea that existing structures remain untouched contradicts one of SOA's well-known challenges.

Memory tip: Think of SOA like planting an orchard - you don't eat fruit the day you plant trees. The payoff is a strategic, long-term harvest once enough services (trees) are growing and shared. If an answer promises immediate, effortless gains from SOA, it's a distractor.
