In a production environment, you are running a multi-AZ Aurora PostgreSQL cluster behind an RDS Proxy to handle thousands of concurrent connections from microservices hosted on EKS. You notice that under certain traffic patterns, your RDS Proxy connection pool saturates, even though the Aurora cluster itself is not maxed out on CPU or memory. Explain possible causes of this saturation. How does RDS Proxy manage connection pooling at the session and transaction level? What are the trade-offs between session-based and transaction-based pooling modes, and how would you diagnose or fix this issue without scaling Aurora or the proxy itself?

Questions were about commands and instruments for debugging Linux. Proc fs / docker / fs nodes . They asked strange situation tasks about an application with cats and dogs, and wait for answers about Redis ques and process parallelism. Another question was about the fictional pipeline without any requirements. And at the end was a live coding session with tasks about swap "tricks" keys and values in dictcionaries.
