PAS-C01 Technology Practice Question
This PAS-C01 practice question tests your understanding of technology. 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.
An SAP environment uses Amazon CloudWatch to monitor EC2 instances. The operations team wants to receive a notification when the CPU utilization exceeds 90% for 5 consecutive minutes. Which AWS service should they use?
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
Amazon CloudWatch Alarms with Amazon SNS.
Amazon CloudWatch Alarms can monitor a metric (like CPUUtilization) and trigger an action when the metric crosses a defined threshold for a specified number of consecutive evaluation periods. By setting the alarm to evaluate CPU utilization > 90% for 5 consecutive minutes (e.g., 5 periods of 1 minute each) and configuring the alarm action to publish to an Amazon SNS topic, the operations team receives a notification directly. This is the native, serverless way to react to CloudWatch metrics without additional infrastructure.
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 confuse AWS Config (configuration compliance) or CloudTrail (API auditing) with real-time metric monitoring, or they think CloudWatch Logs can directly alert on CPU metrics, but only CloudWatch Alarms with SNS provide the precise threshold-based notification for CloudWatch metrics.
Detailed technical explanation
How to think about this question
Under the hood, a CloudWatch Alarm transitions through states (OK, ALARM, INSUFFICIENT_DATA) based on the metric's value over a number of evaluation periods. The '5 consecutive minutes' requirement is implemented by setting the 'Period' to 60 seconds and 'Evaluation Periods' to 5, with 'Datapoints to Alarm' also set to 5. A real-world scenario where this matters is when an SAP HANA instance experiences a memory or CPU spike due to a sudden batch job; the alarm can trigger an SNS notification to a pager or email, allowing the team to scale up or investigate before the instance becomes unresponsive.
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 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.
