A recovery policy needs minimal data loss and a short recovery time after a regional failure. The proposed solution keeps only nightly backups and no tested restore procedure. What should the engineer conclude?

1. Ignore source data changes between nightly backups because they are automatically reconstructed.
2. Backup-job success proves every regional recovery completes instantly.
3. RPO and RTO are identical labels for instance CPU utilization.
4. Assess backup frequency, replication options, restore duration, and tested recovery against the actual RPO and RTO.
