The correct answer is B. Migrate the database to Amazon Aurora with cross-Region replicas. Amazon Aurora supports cross-Region read replicas with typical replication latency under 1 second, providing near-real-time reads for applications in a secondary Region.

Question
A database is on an Amazon RDS MySQL 5.6 Multi-AZ DB instance that experiences highly dynamic reads. Application developers notice a significant slowdown when testing read performance from a secondary AWS Region. The developers want a solution that provides less than 1 second of read replication latency. What should the solutions architect recommend?
Options
- AInstall MySQL on Amazon EC2 in the secondary Region.
- BMigrate the database to Amazon Aurora with cross-Region replicas.
- CCreate another RDS for MySQL read replica in the secondary Region.
- DImplement Amazon ElastiCache to improve database query performance.

Explanation
Amazon Aurora supports cross-Region read replicas with typical replication latency under 1 second, providing near-real-time reads for applications in a secondary Region. Migrating to Aurora allows the database to handle highly dynamic read workloads efficiently, which standard RDS MySQL cross-Region read replicas may not achieve due to higher replication latency.
