DBS-C01 Management and Operations Practice Question
A database administrator needs to monitor the number of connections to an Amazon RDS for PostgreSQL DB instance. Which Amazon CloudWatch metric should be used?
⚠ Common exam trap
The trap here is that candidates might confuse CPUUtilization or memory metrics with connection monitoring, but AWS explicitly provides the DatabaseConnections metric for this purpose, and the exam tests your knowledge of which specific CloudWatch metric maps to which operational need.
