A company must replicate object data to a recovery Region. Its RPO cannot be assumed zero, and administrators must know whether the replication goal is met. Which design is appropriate?

1. Disable versioning and rely on a public DNS record for replication.
2. Use cross-Region replication with monitored replication status and measured recovery procedures.
3. Use only an S3 bucket alias in the second Region.
4. Assume enabling replication instantly copies every existing object and every later write.
