Which of the following statements is false?

Question

Options

• AThe design standardization of service contracts helps increase interoperability between services.
• BDesign standardization can introduce organizational and cultural challenges because it requires that
• CThe design standardization of service contracts helps avoid the need for transformation technologies.
• DDesign standardization is not relevant to the design of service compositions. It is only relevant to the

• B
  7% (2)
• C
  3% (1)
• D
  90% (27)

Explanation

Option D is false because design standardization is directly relevant to service compositions - when multiple services are assembled into a composition, standardized contracts are what allow them to interact seamlessly without requiring custom adapters or transformation logic at each integration point.

Why the distractors (A, B, C) are true - and therefore not the answer:

• A is true: standardized contracts create a common "language" across services, which is the definition of interoperability.
• B is true: standardization requires teams and departments to agree on and follow shared conventions, which is a real governance and cultural challenge.
• C is true: if all services already speak the same standard, there's no need for middleware or transformation layers to translate between different data formats or protocols.

Memory tip: Think of design standardization like a universal power outlet standard - it matters everywhere electricity is used, not just at the wall. Service compositions are where multiple services "plug in" to each other, so standardization matters most there, not least. Any answer claiming standardization is irrelevant to compositions is the opposite of true.
