You deploy a containerized application (App1) to an Azure Container Instance (ACI1). You need ACI1 to automatically restart the container when App1 becomes unresponsive. What should you add to App1's YAML configuration?

A liveness probe detects if an application within a container is running correctly and can restart the container if it fails. This directly addresses the requirement for ACI1 to automatically restart App1 when it becomes unresponsive. A readiness probe, conversely, determines if a container is ready to serve traffic, not if it needs a restart due to unresponsiveness. Connection Monitor and IP flow verify are networking diagnostic tools within Azure Network Watcher; they are used for analyzing network connectivity and traffic flow, not for managing container lifecycle or restarting unresponsive applications.
