AWS Certified SysOps Administrator – AssociateMonitoring, Logging, and RemediationEasy
A SysOps administrator needs to set up a dashboard to visualize the health and performance of an application running on Amazon EC2 instances. The dashboard should display CPU utilization, network I/O, application-specific metrics (e.g., request count, error rates from logs), and custom alarms. The solution must be easy to configure and provide a unified view. Which AWS service is best suited for creating this dashboard?
- AAmazon OpenSearch Service Dashboards
- BAmazon QuickSight
- CAmazon CloudWatch Dashboards
- DAWS X-Ray service map
Show answer & explanationAnswer & explanation
Correct answer: C. Amazon CloudWatch Dashboards
Amazon CloudWatch Dashboards provide a customizable home page in the CloudWatch console that you can use to monitor your resources in a single view. You can add widgets for various metrics (EC2, custom), logs, and alarms, making it ideal for a unified application health dashboard.
Why the other options are wrong
- A. OpenSearch Service Dashboards (formerly Kibana) are used for visualizing data stored in OpenSearch Service, typically logs. While powerful, CloudWatch Dashboards are native to AWS monitoring and better suited for combining all types of CloudWatch data (metrics, logs, alarms) in one place.
- B. QuickSight is a business intelligence service for data visualization and analytics, not primarily for operational monitoring of AWS resources and alarms.
- D. X-Ray service maps visualize application component interactions and trace requests, which is different from a general health and performance dashboard with metrics and alarms.
