Architecture · interview question
Which move is the best default when layered architecture becomes part of this workflow?
Multiple choiceEasychapter-18-curatedpremiumarchitecturelayered-architecture
Answer and explanation
Correct answer
D. Separate API, service, and data boundaries when that separation clarifies responsibility and testing seams.
Why
Separate API, service, and data boundaries when that separation clarifies responsibility and testing seams. That is the stronger engineering move because interviewers like candidates who can justify each layer in terms of ownership and change cost. Adding layers without responsibility clarity just creates longer import chains and meetings.
