An application uses Aurora PostgreSQL in one Region. It needs a second Region for local reads and disaster recovery. Small replication lag and potential loss of recent transactions during an unplanned regional outage are acceptable. The team wants a managed cross-Region design. Which solution best fits?

1. Add a reader to the primary regional Aurora cluster and assume it remains available after the entire primary Region fails.
2. Add RDS Proxy in the second Region without creating any replicated secondary database.
3. Create an Aurora Global Database with a secondary cluster in the recovery Region and test managed failover and application write-endpoint redirection.
4. Copy a database snapshot once per month and use it as the continuously updated local read endpoint.
