Explanation:
The correct answer is A. Amazon CloudWatch composite alarms allow you to combine multiple alarms into a single alarm condition, which is ideal for the given scenario. It ensures that the company is only alerted when both CPU utilization exceeds 50% and read IOPS are high simultaneously. This approach helps in reducing false alarms and accurately identifying the conditions that require immediate attention.
Ultimate access to all questions.
In the process of migrating an application to Amazon EC2, a solutions architect is tasked with setting up infrastructure metric alarms. The company requires alarms that do not trigger on short CPU utilization spikes over 50% but should be alerted if high CPU utilization coincides with high disk read IOPS. Additionally, the architect must minimize false alarms. What is the recommended approach?
A
Utilize Amazon CloudWatch composite alarms to monitor and combine multiple metrics into a single alarm condition.
B
Implement Amazon CloudWatch dashboards for an at-a-glance view of metrics to expedite issue resolution.
C
Employ Amazon CloudWatch Synthetics canaries for continuous application health and performance monitoring, triggering alarms on detected issues.
D
Set up single Amazon CloudWatch metric alarms with defined thresholds to capture specific metric conditions that necessitate immediate attention.
