Mule domains and shared resource configuration
When an on-premises Mule domain earns its place, how applications reference it unambiguously, how domains are deployed and edited in Studio, and why shared applications still need individual and combined testing.
Choose Mule runtime domains and domain-shared configuration only for those requirements that clearly benefit from their capabilities.

What the exam expects
- Decide whether a requirement benefits from a Mule domain (shared listener, connection, configuration or dependencies) or is better kept in each application.
- Recognize that domains are a feature of on-premises and hybrid runtimes, not CloudHub.
- Associate an application with the intended domain, including when two installed domains share coordinates.
- Plan the deployment order for a domain and its applications outside Studio.
- Work with domain projects in Studio: inherited modules, remote domains and shared metadata.
Mule domain: a project of shared global configuration that associated applications on the same on-premises runtime reference. Shared resource: a global element such as a connector configuration, shared property or scheduler pool defined in the domain. Default domain: the domain an application uses when it declares no domain dependency. Remote domain: a domain Studio resolves from a Maven repository instead of the workspace (Shared Resources, Studio domains).
