A manufacturing company’s website uses an Amazon Aurora PostgreSQL DB cluster.
Which configurations will result in the LEAST application downtime during a failover?
(Choose three.)
Use the provided read and write Aurora endpoints to establish a connection to the Aurora DB cluster.
Create an Amazon CloudWatch alert triggering a restore in another Availability Zone when the primary Aurora DB cluster is unreachable.
Edit and enable Aurora DB cluster cache management in parameter groups.
Set TCP keepalive parameters to a high value.
Set JDBC connection string timeout variables to a low value.
Set Java DNS caching timeouts to a high value.
As I recall, the answer is:
Use the provided read and write Aurora endpoints to establish a connection to the Aurora DB cluster.
