An ecommerce app keeps many idle connections to an Amazon Aurora cluster and during peaks the database returns "Too many connections." Clients also receive errors. Which change will fix this issue?

Deploying RDS Proxy will fix the issue because it pools and shares database connections, reducing the number of open connections to the Aurora cluster. This helps prevent "Too many connections" errors, especially during peak loads, and improves application resilience. Increasing RCUs and WCUs is for scaling throughput, not managing connection limits. Enabling enhanced networking improves network performance but doesn't address connection count. Changing to burstable instance types is for managing CPU utilization for unpredictable workloads, not for handling excessive database connections.
