AZ400-Q: make rollback an operational decision
A deployment team says, “We can roll back if anything looks wrong.” The release plan has no quantified health signal or owner. What must be added?
- A) A second copy of the README.
- B) Explicit rollback criteria, observable health signals, accountable decision owners, and a tested rollback action. ✓
- C) A longer deployment timeout.
- D) A public DNS record.
Answer: B. A rollback strategy is executable only when its trigger, evidence, authority, and action are defined and tested before the incident.
Why not the others: Documentation copies, timeout, and DNS do not define an operational rollback decision.
