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?

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?

An administrator is deploying a three-tier application on a Nutanix Enterprise Cloud consisting of web, application, and database VMs. Traffic between the servers must be limited to specific services/ports. There is an application layer firewall VM deployed on one host in the cluster.

In which way should the administrator meet this requirement?

A.
Create a network for each type of VM, and use policy-based routing to control the traffic flow

D.
Categorize the VMs in Prism Central and utilize Flow to set a security policy
Answers
D.
Categorize the VMs in Prism Central and utilize Flow to set a security policy
Suggested answer: D

Explanation:

For a multi-tier application where traffic must be limited to specific services and ports across web, application, and database VMs, the optimal approach is to use microsegmentation features provided by Nutanix. Option D, 'Categorize the VMs in Prism Central and utilize Flow to set a security policy,' is the correct choice.

Nutanix Flow allows for detailed security policies that control VM-to-VM traffic within the same cluster, effectively managing access and communication based on specified criteria like VM category, service, or application type. This solution enables precise control over traffic flows, enhancing security without requiring additional physical or virtual network segmentation.

Reference: Nutanix Flow capabilities are detailed in Nutanix Prism Central's documentation, which explains how to implement microsegmentation and security policies for application-specific traffic management.
