- A
Configure Amazon CloudWatch Anomaly Detection on the relevant RDS metrics (e.g., DatabaseConnections, ReadLatency, WriteLatency) and set an alarm to notify when the metric breaches the anomaly band.
CloudWatch Anomaly Detection automatically builds a baseline and adapts to behavior changes over time, including seasonality. It can trigger alarms when metrics deviate significantly from predicted patterns.
- B
Use Amazon RDS Performance Insights to analyze database load and set CloudWatch alarms on the DBLoad metric with static thresholds.
Why wrong: Performance Insights helps identify performance bottlenecks but does not provide automated baseline anomaly detection. With static thresholds, alarms must be manually adjusted and do not adapt to seasonal patterns.
- C
Enable Amazon CloudWatch Metrics Explorer to create a dashboard that visualizes the metrics and manually review for anomalies.
Why wrong: Metrics Explorer creates interactive dashboards but does not provide automatic anomaly detection or alerting. It requires manual observation.
- D
Use AWS X-Ray to trace database queries and set alarms on trace segment durations.
Why wrong: X-Ray is for tracing requests through distributed applications, not for monitoring database instance-level metrics. It does not provide anomaly detection on RDS metrics.
Quick Answer
The answer is Amazon CloudWatch Anomaly Detection, which should be configured on relevant RDS metrics like DatabaseConnections, ReadLatency, and WriteLatency. This is correct because CloudWatch Anomaly Detection uses machine learning to continuously analyze historical metric patterns and establish a dynamic baseline that automatically adapts to seasonal trends and gradual changes in normal behavior, such as predictable traffic spikes or slow shifts in query load. On the AWS Certified SysOps Administrator Associate SOA-C02 exam, this question tests your understanding of adaptive monitoring versus static thresholds—a common trap is choosing simple CloudWatch alarms with fixed limits, which fail when baseline behavior evolves. The key distinction is that anomaly detection learns patterns over time, making it ideal for RDS performance monitoring where workloads fluctuate. For a memory tip, think of it as a "self-learning guardrail": the band expands and contracts with your database’s natural rhythm, so you never have to manually tweak thresholds again.
SOA-C02 Monitoring, Logging, and Remediation Practice Question
This SOA-C02 practice question tests your understanding of monitoring, logging, and remediation. 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 company runs a multi-tier application that uses an Amazon RDS for PostgreSQL database. The SysOps administrator needs to monitor the database for performance anomalies, such as sudden spikes in connections or query latencies. The administrator wants to receive alerts when metrics deviate from their expected baseline. The solution must automatically adjust to changes in normal behavior over time, such as seasonal patterns. Which AWS service or feature should the administrator use?

Correct answer & explanation
Configure Amazon CloudWatch Anomaly Detection on the relevant RDS metrics (e.g., DatabaseConnections, ReadLatency, WriteLatency) and set an alarm to notify when the metric breaches the anomaly band.
Amazon CloudWatch Anomaly Detection uses machine learning to continuously analyze metric patterns and establish a dynamic baseline that adapts to seasonal trends and gradual changes in normal behavior. By applying anomaly detection to RDS metrics like DatabaseConnections, ReadLatency, and WriteLatency, the administrator can set an alarm that triggers when a metric deviates outside the calculated anomaly band, automatically adjusting to evolving traffic patterns without manual threshold updates.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Performance Insights (a diagnostic tool for analyzing database load) with a monitoring and alerting solution, overlooking that it does not provide adaptive baselines or automatic anomaly detection.
Detailed technical explanation
How to think about this question
CloudWatch Anomaly Detection uses a statistical model based on the metric's historical data, applying a band (upper and lower thresholds) that is recalculated periodically (e.g., every 2 hours) to reflect recent behavior. The band width is controlled by a sensitivity setting (from 0 to 100), where lower values create a tighter band for stricter anomaly detection. In a real-world scenario, an e-commerce site with weekly traffic spikes on Cyber Monday would benefit because the model learns the recurring pattern and does not flag the expected surge as an anomaly.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
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
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
