Which statement about persistence across multiple nodes is true?

• A. Persistence can be replicated across several nodes.
• B. Persistence is always local to a single JVM.
• C. Object Store cannot be replicated.
• D. Persistence only happens in CloudHub.

Answer: (A)

The key idea is that data kept by the Object Store can be shared across multiple Mule nodes in a cluster. In a multi-node deployment, you want certain state to be available to every node, so if one node goes down another can continue without losing that data. Mule achieves this by using a persistent or distributed object store that is replicated (or backed by a shared database/cache) across the nodes. When configured this way, what you write on one node is propagated to the others, enabling consistent state and reliable failover.

So, the statement that persistence can be replicated across several nodes is the correct one. It’s not limited to a single JVM, and it isn’t restricted to CloudHub or to non-replicable object stores—the right persistent setup allows replication across nodes in a cluster.
