DBS-C01 Management and Operations Practice Question
Network Topology
A database administrator runs the above AWS CLI command. What is the purpose of the command?
⚠ Common exam trap
Watch out — candidates often confuse the metric name `DatabaseConnections` with other common RDS metrics like `FreeStorageSpace` or `CPUUtilization`, or assume the command retrieves performance metrics without carefully reading the `--metric-name` parameter.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Retrieve average number of database connections for mydb.
The AWS CLI command `aws cloudwatch get-metric-statistics` with the namespace `AWS/RDS`, metric name `DatabaseConnections`, and statistic `Average` retrieves the average number of database connections for the specified DB instance `mydb` over the given time period. The `--metric-name DatabaseConnections` parameter explicitly targets the connection count metric, making option B correct.
