Services are ideally designed to be:

Question

Options

• Aagnostic and reusable
• Bunidirectional and semi-granular
• Clinear and logistically decomposable
• Dreturnable and non-standardized

• A
  84% (16)
• B
  5% (1)
• C
  11% (2)

Explanation

Agnostic and reusable (A) captures the core principle of service-oriented design: a well-designed service should be independent of any specific consumer's context (agnostic) so it can be leveraged across multiple applications and use cases (reusable), maximizing ROI and reducing duplication.

B is wrong because "unidirectional" and "semi-granular" aren't meaningful service design goals - services typically support bidirectional communication and should be either fine- or coarse-grained based on need, not "semi" anything. C is wrong because services are designed around capabilities and boundaries, not linear workflows or logistical decomposition - those terms describe process modeling, not service architecture. D is wrong because "returnable" is nonsensical in this context, and standardization is actually a goal of service design, not something to avoid.

Memory tip: Think "A = Adaptable to Anyone" - a great service doesn't care who calls it or why, making it universally reusable.
