SOA Certified Professional – Analyst — Question 6

When applying the Service Loose Coupling design principle, we want to __________________ the coupling of the service logic to the service contract because that allows the service contract to remain __________________ from the service logic.
Select the correct answer.

Answer options

• A. increase, decoupled
• B. reduce, decoupled
• C. increase, coupled
• D. reduce, coupled

Correct answer: A

Explanation

The correct answer is A because the principle of Loose Coupling encourages increasing the separation between service logic and service contracts, which helps in maintaining flexibility and adaptability. Options B, C, and D do not align with this principle as they either suggest reducing the coupling or incorrectly state the nature of the relationship between service logic and contracts.
