SOA-C02 Monitoring, Logging, and Remediation Practice Question
This SOA-C02 practice question tests your understanding of monitoring, logging, and remediation. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 SysOps administrator needs to monitor the CPU utilization of an EC2 instance and receive an alert when it exceeds 80% for 10 consecutive minutes. Which AWS service should be used to configure this monitoring and alerting?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Amazon CloudWatch Alarms
Amazon CloudWatch Alarms is the correct service because it allows you to monitor a specific metric, such as EC2 CPUUtilization, and trigger an action (e.g., an SNS notification) when the metric crosses a defined threshold (80%) for a specified number of consecutive evaluation periods (10 minutes, which with the default 1-minute period equals 10 datapoints). This directly fulfills the requirement for threshold-based alerting on a single metric over a sustained duration.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Amazon EventBridge
Why it's wrong here
EventBridge is for event-driven patterns, not continuous metric monitoring.
✓
Amazon CloudWatch Alarms
Why this is correct
CloudWatch Alarms monitor metrics and trigger actions based on threshold breaches.

✗
AWS Trusted Advisor
Why it's wrong here
Trusted Advisor provides cost, performance, and security recommendations, not monitoring.
✗
AWS Config
Why it's wrong here
AWS Config is used for resource inventory and compliance, not real-time metric monitoring.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse Amazon EventBridge (which can trigger actions based on events but cannot natively evaluate sustained metric thresholds) with CloudWatch Alarms, or mistakenly think AWS Config or Trusted Advisor can monitor real-time performance metrics, when they are designed for configuration compliance and best-practice recommendations respectively.
Detailed technical explanation
How to think about this question
Under the hood, CloudWatch Alarms evaluate a metric against a threshold using a statistic (e.g., Average) over a specified number of periods; for 10 consecutive minutes with a 1-minute period, you set the 'period' to 60 seconds and 'evaluation periods' to 10 with 'datapoints to alarm' also set to 10 to ensure strict consecutiveness. A subtle behavior is that if you use a period longer than 1 minute (e.g., 5 minutes), you must adjust the evaluation periods accordingly, and the alarm state transitions (OK -> ALARM -> OK) follow a three-state model that can cause delayed notifications if the metric oscillates near the threshold.

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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
