    Select one answer
  • A workload in a production account runs application instances and a stateful database across Availability Zones in one Region. Its disaster recovery account holds backups in a second Region. A new requirement is to recover after a complete primary-Region outage within 30 minutes. A recent exercise took four hours to restore the database and rebuild the application. Which change should the team prioritize? One answer
    Select one answer
  • A central operations account needs to investigate a payment service deployed in multiple workload accounts. The service already writes structured rejection events to CloudWatch Logs, but it publishes no rejection metric. Operators need a threshold notification and a centralized view of the relevant telemetry without changing application code. Which TWO actions together meet these requirements? (Select TWO.) Select all that apply
    Select all that apply
