Correct answer & explanation

Amazon RDS Performance Insights
Amazon RDS Performance Insights provides real-time information about active database connections and sessions. Option A (AWS Trusted Advisor) is incorrect because it offers best practice recommendations, not connection monitoring. Option B (VPC Flow Logs) is incorrect because they capture network traffic metadata, not database-level connection details. Option D (AWS CloudTrail) is incorrect because it records API calls for auditing, not real-time database connections.
