Which fully managed data visualization service lets you query, correlate, and visualize operational metrics, logs, and traces from multiple sources?

• A. Amazon CloudWatch
• B. Amazon Managed Grafana
• C. AWS Health Dashboard
• D. AWS Management Console

Answer: (B)

Cross-source data visualization is best served by a fully managed visualization layer that can pull in data from many sources and correlate it in one place. Amazon Managed Grafana provides exactly that: a fully managed Grafana environment that can connect to diverse data sources—such as CloudWatch metrics and logs, Prometheus, Elasticsearch, and more—and lets you query, correlate, and visualize metrics, logs, and traces across your stack in unified dashboards. With this managed service, AWS handles maintenance, scaling, and security, so you can focus on building insightful dashboards rather than managing infrastructure.

In contrast, CloudWatch dashboards are tight to AWS-native data, offering visualization for AWS resources but not as flexible for cross-source visualization. The Health Dashboard shows AWS service health status, not a general visualization platform. The Management Console is the AWS UI for managing resources, not a data visualization tool.
