NCA-6.10 Exam Dumps : Nutanix Certified Associate NCA v6.10

When a Nutanix cluster alert occurs, indicating maintenance mode issues, the most likely cause is that another node in the cluster is already in maintenance mode. Nutanix clusters enforce restrictions to prevent more than one node from entering maintenance mode simultaneously. This ensures the cluster can maintain resiliency and availability, adhering to the redundancy factor (RF) policy.

If another node is already in maintenance mode, the cluster cannot afford to have additional nodes enter maintenance without compromising data and service availability.
