- A
Review CloudTrail logs for API calls
Why wrong: CloudTrail logs track API calls, not disk space metrics, so they do not help identify the root cause of disk space exhaustion.
- B
Monitor FreeStorageSpace and BinaryLogUsage metrics
Why wrong: BinaryLogUsage is a MySQL-specific metric; RDS for SQL Server uses Transaction Log Disk Usage. Therefore this option is misleading and not correct for SQL Server.
- C
Monitor BackupStorageUsed metric
Why wrong: BackupStorageUsed measures the total backup storage consumed, not the instance's disk space, so it does not help.
- D
Enable Enhanced Monitoring
Enhanced Monitoring provides per-second OS-level metrics including disk utilization, which can reveal disk space consumption and help identify the root cause.

DBS-C01 Enhanced Monitoring Practice Question
This DBS-C01 practice question tests your understanding of monitoring and troubleshooting. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. A key principle to apply: enhanced Monitoring. 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 company's RDS for SQL Server instance is frequently running out of disk space. The instance uses General Purpose SSD (gp2) storage. Which monitoring step will help identify the root cause?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable Enhanced Monitoring
Option D is correct because Enhanced Monitoring provides OS-level metrics such as disk space usage, which can help identify if the instance is running out of disk space due to growth of database files or logs. Option B is incorrect because BinaryLogUsage is a metric specific to MySQL, not SQL Server; RDS for SQL Server uses different metrics like Transaction Log Disk Usage. Options A and C are unrelated to instance disk space.
Key principle: Enhanced Monitoring

Why it's wrong here
BinaryLogUsage is a MySQL-specific metric; RDS for SQL Server uses Transaction Log Disk Usage. Therefore this option is misleading and not correct for SQL Server.
- ✗
Monitor BackupStorageUsed metric
Why it's wrong here
BackupStorageUsed measures the total backup storage consumed, not the instance's disk space, so it does not help.
- ✓
Enable Enhanced Monitoring
Why this is correct
Enhanced Monitoring provides per-second OS-level metrics including disk utilization, which can reveal disk space consumption and help identify the root cause.

Common exam traps
Common exam trap: answer the scenario, not the keyword
A common trap is confusing MySQL-specific metrics (BinaryLogUsage) with SQL Server metrics. For RDS SQL Server, monitor Transaction Log Disk Usage instead.
Detailed technical explanation
How to think about this question
Treat this as a scenario question. Identify the problem, the constraint, and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Enhanced Monitoring
- RDS SQL Server disk space monitoring
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Enhanced Monitoring
Real-world example
How this comes up in practice
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.
