Nutanix Certified Associate Practice Exam

If two nodes in a Nutanix cluster face simultaneous disk failures, what is the expected behavior of VM operations?

1. VMs on nodes with failed disks are unable to write data

2. Nodes with a failed disk are marked as degraded

3. VM read and write operations continue normally

4. VMs are migrated off of nodes with disk failures

The correct answer is: VM read and write operations continue normally

In a Nutanix cluster, when two nodes experience disk failures at the same time, the architecture is robust enough to handle such situations without significant disruption to VM operations. Specifically, VM read and write operations continue normally due to the resilience and redundancy built into the cluster's storage architecture. Nutanix uses a distributed storage system, which allows data to be replicated across multiple nodes. This means that even if certain disks fail, the data can still be retrieved from other locations within the cluster. The hypervisor and data services in Nutanix are designed to reroute I/O operations to maintain availability, thereby ensuring that VMs can continue to operate with minimal impact. This capability to perform read and write operations during disk failures is a core feature of the Nutanix platform, built to ensure high availability and fault tolerance. It allows businesses to maintain operations without significant downtime, even in failure scenarios where multiple components are involved. In scenarios where disk failures occur, the other choices may represent some aspects of cluster behavior but do not encapsulate the overall performance and operational expectations as clearly. For instance, while nodes with failed disks may indeed be marked as degraded and certain precautions may be taken to manage the cluster's health, the primary point of focus for VM operations
