Deployment Pipeline consists of what four environments?

• A. Development, Pre-Prod, Production
• B. Local, Test, Staging, Production
• C. Development, Integration, UAT, Production
• D. Development, Test, Staging, Production

Answer: (D)

A deployment pipeline is built to progressively validate changes before they reach users. The four environments in this progression are Development, Test, Staging, and Production. Development is where code is created and iterated, often in a local or shared dev setup. Test is where automated tests and QA verify that the software behaves as expected and catches defects early. Staging mirrors Production as closely as possible and is used for final validation, performance checks, and release readiness before live use. Production is the live environment where users interact with the system. This sequence provides a clear, risk-reducing path from development to release. Other options introduce environments like Local, Pre-Prod, Integration, or UAT that don’t fit the standard four-stage progression used for routine deployment pipelines.
