Nutanix Updated NCS-Core Exam Questions and Answers by mohamad

If the Foundation applet's progress bar webpage does not load after a refresh during a cluster creation, the consultant should verify if the Foundation process has completed by attempting to connect to any CVM (Controller Virtual Machine) IP address using a web browser. Accessing the CVM will confirm whether the nodes are operational and part of the cluster, thus indicating whether the Foundation process has successfully completed or not.References: Nutanix Bible, NCS-Core 6.8 official documentation on the Foundation process.

For high-performance iSCSI workloads, especially in a Nutanix environment using AHV nodes and a 10 GbE interface, enabling Jumbo Frames on both the Host and the Controller Virtual Machine (CVM) is recommended. Jumbo Frames allow for a larger payload per network packet, which reduces the overhead required to send large amounts of data. Enabling Jumbo Frames on both the host and the CVM ensures that both ends of the communication channel can handle larger packets, thereby optimizing throughput and reducing latency for high-performance workloads.

To ensure additional resiliency in a 20-node ESXi deployment capable of surviving the concurrent loss of two nodes, the consultant should configure the system with a storage reservation and HA (High Availability) admission control each set to 5%, combined with a cluster redundancy factor (RF) of 3. RF3 provides the capability to tolerate the failure of up to two nodes without data loss, thus enhancing the cluster's resilience. This configuration is optimal for maintaining cluster availability and integrity during multiple node failures.References: Nutanix Bible, Nutanix University
