Nutanix NCS-Core Practice Questions

Explanation: To verify that a Nutanix cluster can tolerate a single-node failure, the consultant should use the command nutanix@cvm~$ ncli cluster get-domain-fault-tolerance-status type=node. This command is executed from the Controller Virtual Machine (CVM) and checks the cluster's fault tolerance status specifically for node failures, providing insights into how the cluster's data resiliency and redundancy configurations are holding up against potential single-node failures.

Explanation: In a Nutanix Files deployment within a 20-node AHV cluster, the consultant can deploy a maximum of 16 FSVMs (File Server Virtual Machines). This limitation is based on Nutanix's best practices and design considerations for scalability and performance. The number of FSVMs that can be effectively managed and maintained without degrading the performance of the file-serving operations or the underlying storage infrastructure dictates this maximum.

Explanation: The exhibit shows a screenshot of a Prism Element home dashboard with a notification that “Data Resiliency not possible” and warnings about the inability to get configured fully qualified domain names (fqdn) for hosts identified by their node numbers. In this scenario, the administrator should take action A: Configure the fqdn for the hosts indicated. This is because the warnings on hostname resolution indicate issues with fully qualified domain names (fqdn) configuration for specific nodes. Configuring the fqdn for these hosts can help resolve these issues and improve the data resiliency of the Nutanix cluster1.

Explanation: The error stating "Prism Central is unreachable" when trying to add a cluster to an existing Prism Central with a proxy setup is likely due to incorrect or missing network routing configurations or firewall rules that do not allow communication between Prism Element and Prism Central. The most likely configuration that is missing and needed to resolve this issue is the whitelist of Prism Central VIP inside of Prism Element and Prism Element VIP inside of Prism Central. Whitelisting these Virtual IP addresses ensures that network traffic between these crucial components of the Nutanix architecture is permitted, thus enabling successful communication and registration of the cluster with Prism Central.
