Answer: Implement RDS Proxy and reconfigure applications to route through it.
The correct answer is A: Implement RDS Proxy and reconfigure applications to route through it. RDS Proxy helps manage a pool of database connections and efficiently reuse them, which reduces the overhead associated with frequently opening and closing connections. This addresses the connection rejection errors during peak times without needing to change the instance class or architecture, thus minimizing operational overhead.
