A solutions architect is reviewing the resilience of an application. The solutions architect notices that a database administrator recently failed over the application's Amazon Aurora PostgreSQL database writer instance as part of a scaling exercise. The failover resulted in 3 minutes of downtime for the application. Which solution will reduce the downtime for scaling exercises with the LEAST operational overhead?

الخيارات

  • A Create more Aurora PostgreSQL read replicas in the cluster to handle the load during failover.
  • B Set up a secondary Aurora PostgreSQL cluster in the same AWS Region. During failover, update the application to use the secondary cluster's writer endpoint.
  • C Create an Amazon ElastiCache for Memcached cluster to handle the load during failover.
  • D Set up an Amazon RDS proxy for the database. Update the application to use the proxy endpoint.
