The correct option is AWS Health Dashboard service health. It provides a public, near real time view of AWS service availability across all Regions and it does not require signing in so a single public page can be used to check current status.

AWS Health Dashboard service health is the public Service Health Dashboard that lists ongoing incidents and status updates for AWS services by Region and service. It is maintained by AWS to provide global visibility and it is intended for broad, unauthenticated access so teams can monitor service availability without account credentials.

Amazon CloudWatch is not correct because it focuses on metrics, logs, dashboards, and alarms for your own resources and applications and it does not serve as a public AWS-wide status page.

AWS Config is not correct because it records and evaluates the configuration of your AWS resources for compliance and change tracking and it is unrelated to publishing global service health.

AWS Health Dashboard – Your account health is not correct because that view is personalized to your account and it requires signing in to show account-level events and notifications rather than a public global status page.
