An administrator needs to make sure an RF3 cluster can survive a failure of two complete racks without negatively affecting performance. The current cluster configuration consists of the following: * 30 All Flash Nodes: distributed 10 nodes per rack across three 42U racks * Each node is configured with 20TB usable storage all flash (Cluster Total 600TB Usable) * Current cluster utilization is 500TB storage * Storage containers have Erasure Coding enabled Which configuration changes should be made to make sure the cluster meets the requirements?
An administrator is monitoring the Nutanix v5.15-based AOS cluster performance logs and notices that a SQL server VM is greatly exceeding its intended maximum IOPS. The administrator has confirmed that a QoS policy was previously created for the group of VMs this server is a member of. What are two reasons that this VM would exceed its maximum configured IOPS from the QoS Policy? (Choose two.)
An administrator is planning to deploy a Nutanix cluster to support a few high-performance VMs. This deployment will have the following considerations: * Individual VMs will likely generate network throughputs in the range of 90-100Mbps * Due to the configuration of the VMs, it is unlikely that a node will host more than one or two of them at a time * Individual VMs will communicate with only a few (one or two) remote hosts at a time * Multicast will not be used in the environment * The hosts are connected via two 1GbE network connections How should the administrator configure the network bonds to meet this requirement while maintaining the simplest switch configuration?

An administrator is deploying an application using Nutanix Volumes. After configuring the volume group and connecting the guest's iSCSI initiator to the volume group, they begin performance testing. The administrator learns that performance on the virtual disk attached to the iSCSI initiator is far less than that of a virtual disk connected directly to the VM. Which situation is causing this condition?

An administrator deploys Exchange on a Nutanix cluster. The administrator creates two containers with RF2 configuration: * One container for Exchange * One container for the other VMs The Exchange VM is experiencing I/O performance issues. Which changes to Storage Optimization should be used on the Exchange container to enhance I/O performance?
An administrator needs to replace an aging SAN and move to a hyper-converged infrastructure. The existing environment consists of the following hosts that are connected to the SAN: * 5xAIX hosts * 3x Hyper-V hosts * 9xESXi hosts * 2x physical SQL Clusters (Windows Server 2012R2 hosts) After deploying a Nutanix AHV cluster, which two actions should the administrator take to meet the requirements? (Choose two.)
An administrator has an existing Nutanix seven-node cluster running at RF2 that must be changed to have the following capabilities: * RF3 set for the cluster * Performance tier deduplication What is the minimum memory needed on the CVMs to allow for these capabilities?

A consultant needs to image nodes that cannot be discovered with the Foundation VM

The nodes are connected to a flat stitch and are already part of a Nutanix cluster.

What course of action would result in Foundation success?

A.
Use the customer's top of rack switch.
Answers
A.
Use the customer's top of rack switch.
B.
Buy a new flat switch.
Answers
B.
Buy a new flat switch.
C.
Bare metal image the nodes.
Answers
C.
Bare metal image the nodes.
D.
Change the physical connections.
Answers
D.
Change the physical connections.
Suggested answer: C

Explanation:

If nodes cannot be discovered using the Foundation VM and they are already part of a Nutanix cluster, the best course of action is to bare metal image the nodes. This process involves re-imaging the nodes from scratch, which can resolve discovery and communication issues that may be caused by existing configurations or errors within the cluster's networking setup.
