問題文
A steering committee asks what happens if a release turns out to be wrong after it reaches production. What should the architect explain about reverting?
選択肢
- There is no undo operation, so the way back has to be designed in advance as part of the release itself, because it cannot be improvised later.
- Reverting is unnecessary if the deployment was validated first, because a validation that passes proves that the release behaves as designed and therefore that no situation requiring a revert can arise afterwards.
- Reverting is always possible by refreshing production from a sandbox, and the release plan can therefore treat the way back as a standing capability.
- The platform keeps the previous state of every deployed component for 30 days, so a release can be reverted from the deployment status page during that period by selecting the deployment and choosing to undo it, which restores both the components and any records they created.
