NCS-Core Exam Dumps : Nutanix Certified Services Core Infrastructure Professional (NCS-Core 6.8)

The failure to discover nodes during installation can often be attributed to the lack of IPv6 support on the network, especially if the Foundation process relies on IPv6 for node discovery. If IPv6 is not enabled on the customer’s switch, the discovery packets may not be properly routed, resulting in the nodes not being discovered. Enabling IPv6 on the switch could resolve this discovery issue.

When looking for documents that identify specific ports such as the Shared IPMI port on nodes, the best location within the Nutanix Support Portal is the Hardware Replacement Documentation. This section specifically deals with physical components and their configurations, making it the most appropriate resource for identifying physical port locations and specifications related to specific Nutanix hardware models.References: Nutanix Support Portal, Nutanix Bible, and NCS-Core 6.8 materials specifically mentioning hardware documentation.

Increasing the number of vCPUs from 2 to 4 can indeed reduce login times by providing more processing power to handle the login requests. However, this action will have two main impacts on the cluster:

A. Increase CPU utilization%: By increasing the number of vCPUs, you are effectively increasing the demand for CPU resources. This will result in a higher percentage of the CPU being utilized.

B. Increase CPU ready%: CPU Ready is a measure of the amount of time a virtual machine is ready to run against the pCPU, but is waiting to be scheduled on the physical CPU. By increasing the number of vCPUs, you are increasing the number of virtual machines that are ready to run, which can increase the CPU Ready percentage.

Increasing the vCPU count does not directly affect memory utilization, so options C and D are not correct.
