Câu 29: S90.03: SOA Design Architecture (S90-03A)

I have a service composition with three services. Service A retrieves a list of country codes from a database and keeps this data in memory while interacting withService B and Service C. However, because Service A is concurrently invoked many times, and because each instance of Service A loads its own copy of the country code data into memory, the demands on the overall infrastructure become too high and performance and reliability are negatively affected. Which service- orientation principle can be applied to help solve this problem?Select the correct answer.

1. A. Service Reusability
2. B. Service Autonomy
3. C. Service Abstraction
4. D. Service Statelessness — đáp án hiện tại
