Free Nutanix NCS-Core Exam Dumps Questions & Answers

A guest VM is reported to have poor storage performance. It has an I/O profile of 80% read. 20% write, and the HDDs form more than 50% of the read source.
What should an administrator do to resolve this issue?

• A.Increase the OPLOG
• B.Increase the write cache
• C.Increase SSD capacity
• D.Use HDDs with higher RPM

Refer to the exhibit.

An administrator logs in to Prism and sees the status shown in the exhibit within the Hardware Diagram section.
What should the administrator do?

• A.Check status of applications running on the cluster and call support
• B.Restart all CVMs for the cluster to check, confirm health and repartition and add the disks.
• C.Resolve all alerts and re-import the disks to make sure there is no service disruption.
• D.Reseat all disks immediately. If this does not help, reseat the nodes.

An administrator receives reports that VDI desktop performance in an 8-node Nutanix VDI environment is poor. Opening applications takes between 1 and 2 minutes.
When investigating the issue, the following conditions are found:
* Cluster memory utilization: 80%
* Cluster SSD utilization: 70%
* Average VM CPU Wait Time: 11%
* CVM CPU utilization: 75%
Which action should be taken to improve VDI performance?

• A.Add memory to the nodes in the cluster.
• B.Increase the amount of SSD storage in the cluster.
• C.Add CPU resources to the cluster.
• D.Increase the number of vCPU cores allocated to the CVM.

• B.Open terminal and configure via ifconfig command.
• C.Ensure the vNIC is set to bridged adapter.
• D.Configure the static IP address through the desktop virtualization software.

An administrator needs to make sure an RF2 cluster can survive a complete rack failure without negatively effecting workload performance. The current cluster configuration consists of the following:
* 30 nodes: distributed 10 nodes per rack across three 42U rack
* Each nodes is configured with 40TB usable storage all flash (Cluster Total 1.2 PB Usable)
* Current cluster utilization is 900TB storage
Which configuration changes should be made to make sure that the cluster meets the requirements?

• A.Expanse the cluster by adding 9 nodes to a new 42U rack
• B.Expanse the cluster by adding 3 additional nodes per rack, 9 nodes total.
• C.Expanse the cluster by adding 2 additional nodes per rack, 6 nodes total.
• D.Expanse the cluster by adding 8 nodes to a new 42U rack
