MuleSoft Certified Integration Architect – Level 1 — Question 73
A Mule application is deployed to a cluster of two (2) customer-hosted Mule runtimes. Currently, the node named Alice is the primary node and the 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 is 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?
Answer options
- A. Files are polled from the Bob node Bob is now the primary node
- B. Files are polled from the Bob node Alice is now the primary node
- C. Files are polled from the Alice node Alice is now the primary node
- D. Files are polled from the Alice node Bob is now the primary node
Correct answer: A
Explanation
When the primary node Alice fails, the secondary node Bob takes over and continues to poll for files. After Alice restarts, Bob remains the primary node because it was already handling the workload during Alice's downtime, thus files are polled from Bob and Bob is the primary node.
