A compliance review finds that backup jobs succeed, but no one has verified whether a supported RDS backup can be restored within the documented RTO. Operations wants a recurring, isolated validation process without directing production users to the restored database. Which actions meet this goal? Select 2 answers.

1. Use AWS Backup restore testing for the supported recovery points and configure the required restore parameters and role.
2. Measure only the duration of the backup creation job and compare that value with the restore RTO.
3. Use successful backup-job status as conclusive proof that application recovery meets the RTO.
4. Validate the restored resource and application-level recovery requirements, and compare the observed recovery time with the RTO.
5. Assume Multi-AZ failover and backup restoration have identical recovery times.
