SOA-C02 Question 27
Select 3Your company has multiple EC2 instances running across different regions to support a global application. As an AWS SysOps Administrator, you need to create a CloudWatch dashboard that provides real-time visibility into the CPU utilization and disk read/write operations for all EC2 instances across these regions. What steps should you take to achieve this?
- A
Create a CloudWatch dashboard and add widgets for CPU utilization and disk metrics for each EC2 instance manually.
- B
Use the CloudWatch cross-account cross-region feature to aggregate metrics from all regions into a single dashboard.
- C
Ensure you select the correct region for each EC2 instance when adding metrics to the CloudWatch dashboard.
- D
Use the AWS CLI or SDK to automate the creation of the CloudWatch dashboard with metrics from all regions.
- E
Enable detailed monitoring on all EC2 instances to ensure high-resolution metrics are available for the dashboard.
Show answer and explanation
Correct answers: A, C, E
Explanation
To create a CloudWatch dashboard that provides real-time visibility into metrics for EC2 instances across regions, you need to manually add widgets for the required metrics and ensure you select the correct region for each instance. Additionally, enabling detailed monitoring is crucial to ensure high-resolution metrics are available for accurate monitoring. Automation via CLI or SDK is not explicitly required in this scenario, and the cross-account cross-region feature is not relevant as the question focuses on a single account context.
- A. Correct.
Correct. You can manually create a CloudWatch dashboard and add widgets to track specific metrics like CPU utilization and disk operations for each EC2 instance.
- B. Incorrect.
Incorrect. The cross-account cross-region feature is not required in this scenario as the question does not involve multiple AWS accounts.
- C. Correct.
Correct. When adding metrics to a CloudWatch dashboard, you must ensure metrics are pulled from the correct region where the resources are running.
- D. Incorrect.
Incorrect. While automation is useful, the question does not specify a requirement for using the AWS CLI or SDK. Manual creation of the dashboard is sufficient.
- E. Correct.
Correct. Enabling detailed monitoring on EC2 instances ensures high-resolution (1-minute) metrics are available, which is critical for real-time visibility.
