Which approach meets these requirements with no negative performance impact?
Enable synchronous replication.
Enable asynchronous binlog replication.
Create an Aurora Global Database.
Copy Aurora incremental snapshots to the us-east-1 Region.
Explanations:
Synchronous replication in Aurora introduces higher latency, which could negatively impact performance. It also doesn’t guarantee the 1-minute RPO and 2-minute RTO for cross-region disaster recovery.
Asynchronous binlog replication has a higher risk of data loss compared to synchronous replication. It doesn’t meet the 1-minute RPO and 2-minute RTO requirements for disaster recovery.
Aurora Global Database is designed for cross-region disaster recovery with low-latency replication. It meets the requirements of 1-minute RPO and 2-minute RTO, with no negative impact on performance.
Copying Aurora incremental snapshots provides a backup solution but does not meet the required RPO and RTO since snapshots can take longer to copy and restore, and they do not provide real-time replication.
I strategize that the answer is:
Create an Aurora Global Database.
