AWS Certified Solutions Architect Professional SAP-C02 Practice Question

A company runs a critical application on an Amazon Aurora PostgreSQL Global Database. The primary cluster is in us-east-1, and a secondary read-only cluster is in us-west-2 for low-latency reads and disaster recovery. A regional outage has made the primary cluster in us-east-1 completely unavailable. The solutions architect must restore write capability in us-west-2 as quickly as possible. What is the MOST operationally efficient way to promote the us-west-2 cluster to become the new primary?

  • Wait for Aurora to perform an automatic cross-Region failover; no manual action is required.

  • Detach the us-west-2 cluster from the global database and promote it to a standalone cluster before directing write traffic to it.

  • From us-west-2, initiate a managed failover (FailoverGlobalCluster with the AllowDataLoss parameter, or the console "Fail over global database" action) to promote the secondary cluster to primary.

  • Start a managed switchover to synchronize the last transactions and promote the us-west-2 cluster with zero data loss.
