300-415 Question #215: Real Exam Question with Answer & Explanation
The correct answer is C: Leave the cluster as is and point to one vManage.. If a vManage cluster is built but redundancy is no longer desired, the most practical approach is to leave the cluster running and simply configure WAN Edge devices and other controllers to connect to only one of the vManage nodes.

Question
An engineer builds a three-node vManage cluster and then realizes that multiple nodes are unnecessary for the size of the company. How should the engineer revert the setup to a single vManage?
Options
- AUse the cluster conversion utility to convert to standalone vManage.
- BRestore vManage from the backup VM snapshot.
- CLeave the cluster as is and point to one vManage.
- DRemove two nodes from the three-node vManage cluster.
Explanation
If a vManage cluster is built but redundancy is no longer desired, the most practical approach is to leave the cluster running and simply configure WAN Edge devices and other controllers to connect to only one of the vManage nodes.
Common mistakes.
- A. There is no supported 'cluster conversion utility' in Cisco SD-WAN to revert a vManage cluster to a standalone instance.
- B. Restoring from a VM snapshot would only be viable if a snapshot of a standalone vManage existed before clustering, which is not implied by the question.
- D. Simply removing nodes from a vManage cluster without proper uninstallation and re-configuration can lead to an unstable or corrupted cluster state, as the cluster state requires all members to be properly managed.
