How can you block access to an object store from other Mule application components?

• A. A private object store can be configured by a particular component to securely hide its data from another component.
• B. Use OSv2 REST API to block access.
• C. Disable the object store.
• D. Store data in a different database.

Answer: (A)

A private object store is the way to isolate data used by a specific component so that other components in the same Mule application cannot access it. By configuring the object store as private for that component, the data it stores stays hidden from others, providing secure separation of state, tokens, or locks that should not be shared. This is precisely how you block cross-component access: the ownership and visibility of the stored data are restricted to the component that created or uses the private store.

The other options don’t fit the need as cleanly. Using an OSv2 REST API targets external access to the store rather than internal component visibility. Disabling the object store would block access entirely for everyone, which isn’t selective or practical. Storing data in a different database changes the storage backend but doesn’t inherently prevent other components from accessing the object store data within the same application, whereas a private object store directly enforces isolation.
