Selected Answer: B
By using Amazon RDS Proxy, your applications can pool and share database connections. This pooling improves scalability by allowing multiple application instances to reuse existing connections. It also makes your applications more resilient to database failures. When a primary database instance fails, RDS Proxy automatically connects to a standby DB instance while preserving application connections. =>https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/rds-proxy.html
