What is a common rollback trigger example?

• A. Rollback should be triggered only by marketing feedback.
• B. High error rate, degraded performance, or failed tests.
• C. Rollout automatically completes regardless.
• D. A scheduled daily timeout.

Answer: (B)

Rollout safety relies on real-time health signals from the running system. A common rollback trigger is when the system shows problems such as a high error rate, degraded performance, or failed tests during the rollout. These signals indicate that the new version isn’t meeting reliability or performance expectations, so rolling back to the previous stable version helps protect users and preserve service quality. Marketing feedback or a rollout finishing automatically don’t reflect technical health during deployment, and a scheduled daily timeout isn’t responsive to actual conditions in real time.
