After the Alice node completely restarts, from what node are the files polled, and what node is now the primary node for the cluster?

A Mule application is deployed to a cluster of two (2) cusomter-hosted Mule runtimes. Currently the node name Alice is the primary node and node named bob is the secondary node. The mule application has a flow that polls a directory on a file system for new files. The primary node Alice fails for an hour and then restarted.

After the Alice node completely restarts, from what node are the files polled, and what node is now the primary node for the cluster?
A . Files are polled from Alice node Alice is now the primary node
B . Files are polled form Bob node Alice is now the primary node
C . Files are polled from Alice node Bob is the now the primary node
D . Files are polled form Bob node
Bob is now the primary node

Answer: D

Explanation:

* Mule High Availability Clustering provides basic failover capability for Mule. * When the primary Mule Runtime becomes unavailable, for example, because of a fatal JVM or hardware failure or it’s taken offline for maintenance, a backup Mule Runtime immediately becomes the primary node and resumes processing where the failed instance left off. * After a system administrator recovers a failed Mule Runtime server and puts it back online, that server automatically becomes the backup node. In this case, Alice, once up, will become backup

Reference: https://docs.mulesoft.com/mule-runtime/4.3/hadr-guide So correct choice is: Files are polled form Bob node Bob is now the primary node
