Quick Answer
The correct answer is to retrieve the average number of database connections for mydb. This is because the AWS CLI command `get-metric-statistics` queries CloudWatch metrics, and when the `--metric-name` parameter is set to `DatabaseConnections` with `--statistics Average` and a `--period` of 300 seconds (5 minutes), it calculates the mean number of active connections over each 5-minute interval for the specified RDS instance. On the AWS Certified Database Specialty DBS-C01 exam, this command tests your ability to monitor RDS performance using CloudWatch, often appearing in scenario-based questions where you must distinguish between metrics like CPUUtilization, FreeStorageSpace, and WriteLatency. A common trap is confusing `DatabaseConnections` with `CPUUtilization` or storage metrics, so remember that connections track concurrency, not resource usage. Memory tip: “Connections Count” — if you see `DatabaseConnections` in the CLI, you are counting active sessions, not hardware load.
This DBS-C01 practice question tests your understanding of management and operations. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A database administrator runs the above AWS CLI command. What is the purpose of the command?
Retrieve average free storage space for mydb.
Why wrong: The metric is not FreeStorageSpace.
Retrieve average number of database connections for mydb.
The metric is DatabaseConnections.
Retrieve average CPU utilization for mydb.
Why wrong: The metric is not CPUUtilization.
Retrieve average write latency for mydb.
Why wrong: The metric is not WriteLatency.
Answer choices
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.
Option A is correct because the command retrieves average DatabaseConnections over 5-minute intervals. Option B is incorrect because it is for CPU, not connections. Option C is incorrect because it is for storage. Option D is incorrect because it is for write latency.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Retrieve average free storage space for mydb.
Why it's wrong here
The metric is not FreeStorageSpace.
Retrieve average number of database connections for mydb.
Why this is correct
The metric is DatabaseConnections.
Related concept
Read the scenario before looking for a memorised answer.
Retrieve average CPU utilization for mydb.
Why it's wrong here
The metric is not CPUUtilization.
Retrieve average write latency for mydb.
Why it's wrong here
The metric is not WriteLatency.
Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
