Nutanix Certified Associate Practice Exam

For a Nutanix cluster to maintain performance integrity during a two-rack failure, what action should the administrator consider?

1. Distributing additional nodes evenly across the existing racks.

2. Adding more flash storage in existing nodes.

3. Regularly pushing data off to slower cloud storage.

4. Upgrading to the latest software version manually.

The correct answer is: Distributing additional nodes evenly across the existing racks.

To maintain performance integrity during a two-rack failure in a Nutanix cluster, distributing additional nodes evenly across the existing racks is essential. This approach ensures that the cluster has adequate resources and can effectively balance the workload across the remaining operational racks. When a failure occurs in a cluster that has been designed for redundancy, having nodes spread evenly allows the system to leverage the remaining nodes to support ongoing operations without overwhelming any single rack. It increases the availability of compute and storage resources that can take over the workloads, thereby reducing the risk of performance degradation. Adding more flash storage in existing nodes could improve speed for certain operations, but does not address the resilience aspect of rack failures. Similarly, pushing data to slower cloud storage might impact performance instead of maintaining it, and while upgrading to the latest software may provide new features or optimizations, it does not inherently resolve the immediate issue of cluster performance during a two-rack failure scenario. Thus, the strategy of redistributing nodes is the most effective way to ensure the integrity of the Nutanix cluster’s performance in such events.
