Selected Answer: B

Amazon RDS Proxy is a fully managed, highly available database proxy for Amazon Relational Database Service (RDS) that makes applications more resilient to database failures. Many applications, including those built on modern serverless architectures, can have a large number of open connections to the database server and may open and close database connections at a high rate, exhausting database memory and compute resources. Amazon RDS Proxy allows applications to pool and share connections established with the database, improving database efficiency and application scalability. With RDS Proxy, failover times for Aurora and RDS databases are reduced by up to 66%

Selected Answer: B

A: DynamoDB != RDS C: Total nonsense D: Lambda for providing connection pooling sound impractical if not impossible. Would be fun to watch someone do this though... B RDS Proxy is specifically made for connection pooling.
