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?
Which two files should be downloaded to deploy Foundation VM on VMware ESXI or AHV Hypervisors? (Choose two.)
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?
During which part of the Knowledge Transfer does the customer learn about Nutanix basics and their environment at a high level?
A consultant has finished imaging all assigned clusters and is ready to close out the engagement Which action is part of the Closeout Checklist?
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?

Refer to Exhibit:

A customer is preparing to expand a cluster with a consultant. The production cluster is comprised of one NX-3460-G7 and two NX-8235 G8 blocks. The running AOS version is 5.20.4.6 and Hypervisor version is ESXi 6.7 U3b. vCenter is also running a 6.7 version.

One NX-3235-G9 block will be added to that cluster (ESXI-NUTA-09 and ESXI-NUTA-10).

The consultant has verified Nutanix documentation and customer's As-Built guide:

* NX-3060-G7 and NX-8035-G8 are hybrid HCI nodes

* ESXi 6.7 U3b is unsupported for the new G9 hardware model

* AOS 5.20.X and ESXi 6 X are end of support

* NX-3060-G7 and NX-8035-G8 hypervisors can be upgraded to the latest ESXi supported version

What actions should be taken before beginning the cluster expansion?

A.
Upgrade vCenter, AOS and ESXi to supported and recommended versions.
Answers
A.
Upgrade vCenter, AOS and ESXi to supported and recommended versions.
B.
Upgrade only AOS and ESXi to supported and recommended versions.
Answers
B.
Upgrade only AOS and ESXi to supported and recommended versions.
C.
Replace all HDDs with SSDs on the Production cluster.
Answers
C.
Replace all HDDs with SSDs on the Production cluster.
D.
Prepare Foundation and the whitelist. json file to deploy ESXi 6.7 U3b on the new nodes.
Answers
D.
Prepare Foundation and the whitelist. json file to deploy ESXi 6.7 U3b on the new nodes.
Suggested answer: A

Explanation:

Before expanding the cluster with the new NX-3235-G9 block, it is critical to ensure that all components are running supported and recommended versions due to compatibility and support issues. Therefore, the necessary actions include: A. Upgrade vCenter, AOS, and ESXi to supported and recommended versions. This step ensures compatibility across all components, particularly important as the new G9 hardware does not support the currently installed version of ESXi. Upgrading these components will also ensure continued vendor support and the stability of the environment. Options B, C, and D do not adequately address the need for vCenter upgrades or the fact that ESXi 6.7 U3b is unsupported for G9, highlighting the necessity for a comprehensive upgrade.
