Which move is the best default when dto mapping becomes part of this workflow?

Answer and explanation

Correct answer

D. Use boundary objects when the partner payload shape is not the shape the rest of your code wants to reason about.

Why

Use boundary objects when the partner payload shape is not the shape the rest of your code wants to reason about. That is the stronger engineering move because candidates who understand translation layers usually explain integrations more clearly. Skipping DTOs can make the service layer speak in partner-specific language forever.
