問題文
Before a Saturday release, a bank wants to know whether the deployment would succeed and whether the tests pass, without changing production yet. Which option achieves this, and what does it leave behind?
選択肢
- A deployment with the option to roll back on error, which applies the changes and then reverses them automatically if any component or test fails, leaving the org exactly as it was before the attempt and producing the same report as a real deployment.
- A deployment to a sandbox, followed by a report of the components and the test results.
- A retrieve from production followed by a file comparison against the repository, which shows exactly which components differ and therefore predicts whether the deployment will succeed.
- A validation-only deployment, which reports the same results as a real deployment but commits nothing to the target org.
