Which Object Store configuration provides isolation within a Cache scope so that data is not accessible by other connectors in the same application?

• A. Define a nested private Object Store within the Cache scope
• B. Configure a public Object Store accessible by all connectors
• C. Use the global Object Store for the entire application
• D. Store data only in memory without Object Store

Answer: (A)

Isolating cached data within a Cache scope is achieved by using a private Object Store that is nested inside that Cache scope. In Mule, the Object Store holds data that components may cache or share during runtime. When the Object Store is private to the Cache scope, only that specific cache region can access the stored entries, so other connectors in the same application cannotSee or reuse them. If you configure a public Object Store, all connectors could read and write to the same store, breaking isolation. A global Object Store is shared across the entire application, which likewise undermines isolation. Storing data only in memory without an Object Store eliminates the caching mechanism entirely and does not provide scoped isolation. Therefore, the nested private Object Store within the Cache scope is the right approach to keep cached data isolated.
