Question

A DevOps team builds an application artifact in their CI pipeline, deploys it to a staging environment for QA testing, and then rebuilds the artifact from the same source branch before deploying to production. QA-approved builds occasionally behave differently in production. Which change to the pipeline BEST resolves this inconsistency?

Accepted Answer

Build the artifact once, assign it an immutable version, and promote that same versioned artifact through staging to production

Answer

Add more automated unit tests to the production build stage to catch differences earlier

Answer

Deploy directly from the source branch to production and skip the staging environment

Answer

Rebuild the artifact in each environment but pin the compiler and dependency versions
