An Amazon RDS for PostgreSQL cluster has automated backups enabled with a 7-day retention. An administrator must create a new RDS cluster containing data no older than 24 hours from the original cluster. Which options satisfy this requirement while minimizing operational effort? (Choose two.)

Restoring the most recent automated snapshot is a straightforward way to create a new cluster with data up to the snapshot's age. RDS automated snapshots are taken daily, and restoring one creates a new DB instance from that point in time. Creating a read replica and then promoting it is also efficient. A read replica continuously replicates data from the primary, so promoting it effectively creates a new, independent cluster with data very close to real-time, satisfying the "no older than 24 hours" requirement with minimal manual effort. Exporting to S3, using AWS DMS, or using pgdump/pgrestore are all valid methods for data migration but involve more operational overhead and manual steps compared to the automated snapshot restore or read replica promotion. These methods typically require more configuration, monitoring, and potential downtime or performance impact during the migration process.
