If a deployment using metadata API encounters a failure in one component, what typically happens?

• A. The deployment continues with remaining components
• B. The deployment is rolled back
• C. The deployment is paused until manual approval
• D. The deployment creates a new environment

Answer: (B)

Deployments via the Metadata API are atomic: all components in the deployment are applied as a single unit, or none are. If any component fails, the deployment is aborted and the system rolls back any changes, leaving the org exactly as it was before the deployment. This all-or-nothing behavior prevents partially applied updates that could create inconsistencies or broken dependencies. When a failure occurs, you typically get an error pointing to the failing component, so you can fix it and re-deploy. If you want to catch issues without applying changes, you can run a validate-only deployment to check for problems beforehand.
