Topic 1 Question 958
A global ecommerce company runs its critical workloads on AWS. The workloads use an Amazon RDS for PostgreSQL DB instance that is configured for a Multi-AZ deployment.
Customers have reported application timeouts when the company undergoes database failovers. The company needs a resilient solution to reduce failover time.
Which solution will meet these requirements?
Create an Amazon RDS Proxy. Assign the proxy to the DB instance.
Create a read replica for the DB instance. Move the read traffic to the read replica.
Enable Performance Insights. Monitor the CPU load to identify the timeouts.
Take regular automatic snapshots. Copy the automatic snapshots to multiple AWS Regions.

A. Create an Amazon RDS Proxy. Assign the proxy to the DB instance.
Explanation: Amazon RDS Proxy:
RDS Proxy is designed to manage connections to the database more efficiently. It can reduce the impact of failovers on the application by maintaining connections and transparently rerouting them to the standby instance during a failover event. By using RDS Proxy, the failover time is reduced because the proxy minimizes the disruption that occurs when the database fails over, thus reducing application timeouts.
