Q108. A consultant needs to upgrade the ESXi hosts on a Nutanix cluster from version 6.7 to 7.0. vSphere DRS and wMoton are working properly. The consultant needs to use One-Click Upgrade.Which setting should be verified by the consultant?
 vSphere HA is enabled.
 Nutanix Prism HA is enabled.
 vSphere DRS Automation level is set to Conservative.
 DRS automation level on all CVMs is disabled.
When upgrading ESXi hosts on a Nutanix cluster using One-Click Upgrade, it is crucial to verify that vSphere HA (High Availability) is enabled. This setting ensures that in the event of host failure during the upgrade process, VMs will be automatically restarted on other hosts in the cluster, maintaining availability and minimizing disruption. Verifying this setting is essential to ensure the resilience of the environment during the upgrade.References:* VMware vSphere Upgrade Documentation* Nutanix Upgrade GuideQ109. An organization subscribes to field advisories from the Nutanix support portal. An administrator receives an email about a rare problem that could cause cluster instability and affect the entire AOS cluster. The organization is running Vmware vsphere 6.x on Nutanix.What action should be taken to resolve this issue?
 Open Prism Element and select Upgrade Software to update AOS.
 File a ticket to NutanixSupport and provide the Field Advisory ID.
 Use VMware Update Manager to update the cluster.
 In Prism Central, select Life Cycle Management and perform LCM update.
Q110. A consultant wants to expand a Nutanix cluster based on Dell PowerEdge servers and notices the nodes have arrived software-less.Which two actions should the consultant take to expand the cluster? (Choose two.)
 Image nodes using Foundation VM/App.
 Use Expand cluster to expand duster.
 Return nodes to factory for imaging.
 Use Expand cluster to image the nodes.
For expanding a Nutanix cluster with software-less Dell PowerEdge servers, the consultant should: A. Image nodes using Foundation VM/App. This tool is designed for initial imaging and configuration of Nutanix nodes, including software installation, which is necessary since the nodes arrived without any software. B. Use the Expand cluster functionality within the existing Nutanix environment once the nodes are imaged. This feature will integrate the newly imaged nodes into the existing cluster, enhancing the cluster’s capacity and performance. Options C and D are not applicable as returning nodes to the factory for imaging is unnecessary with the availability of the Foundation tool, and “Expand cluster to image the nodes” is not a correct procedure as imaging must be completed before expansion.References: Nutanix Foundation Tool Documentation, Nutanix Cluster Expansion Guide.Q111. During a six-node cluster deployment, one node fails to image successfully and Foundation is unable to automatically configure the cluster. The consultant decides to manually complete cluster formation with the successful nodes, then expand the cluster with the remaining unconfigured node.Which command should be used to begin the process?
 cluster status
 cluster create
 cluster start
 cluster expand
Q112. A consultant is onsite with a customer running Foundation VM (FVM) and discovers that there is no connectivity between the FVM and their laptop. The consultant verifies the following:* The consultant’s laptop and Nutanix nodes are plugged into a flat switch.* The laptop, switch and nodes are plugged into supported power supplies.* The laptop network adapters and FVM are configured with their corresponding IP addresses.What is the cause for the connectivity failure to the FVM?
 The switch is not plugged into the power supply.
 Desktop Firewall is blocking ping requests.
 Network cables are not connected.
 Laptop WiFi configured to use DHCP.
Q113. A customer wants to run SAP HANA on a Nutanix cluster with the following characteristics:* AHV nodes* SAP HANA version 2* Production database filesWhich configuration should be recommended to the customer?
 Start with a cluster containing three or more nodes
 Enable only compression for the container that contains the Production database
 Do not enable compression, deduplication. or erasure coding on the storage container
 Plate the SAP HANA Database on the same socket as CVM
Ref:Q114. A consultant is performing a Nutanix Cluster installation on Dell XC Core hardware. The consultant decides to use Foundation Portable for Mac to perform the installation. When the consultant arrives onsite, Foundation Portable is unable to locate the new nodes.Which log should the consultant check to troubleshoot this issue?
 /home/nutanix/foundation/log
 ~/data/logs/foundation.out
 foundation.app/contents/resouces/log
 ~/data/logs/foundation
For troubleshooting issues with Foundation Portable on Mac not locating new nodes, the consultant should check the ~/data/logs/foundation.out log. This log file contains detailed operational entries that describe the activities of the Foundation tool, including any errors encountered during the node discovery process. This can provide insights into why the nodes are not being detected and guide the consultant on the necessary corrective actions.References:* Nutanix Bible: Foundation Deployment and Troubleshooting* Nutanix University: Foundation Tool UsageQ115. An administrator has a 32-node hybrid cluster with CPU, RAM and storage utilization of 80%. A database VM is configured with VM Flash.What is causing this IO latency?
 Controller VM is experiencing high CPU ready time.
 Curator scans causes by ILM constantly moving data.
 VM Flash Mode reduces SSD tier capacity for VMs.
 Database VM is experiencing high CPU ready time.
In a Nutanix cluster, I/O latency can be affected by several factors. Given the scenario where a 32-node hybrid cluster is experiencing I/O latency, one possible cause could be the Information Life Cycle Management (ILM) constantly moving data due to curator scans1.In a Nutanix cluster, ILM is responsible for managing data placement across different storage tiers. It promotes frequently accessed data to higher-performance tiers (like SSDs) and demotes less frequently accessed data to lower-performance tiers (like HDDs)1. This process involves moving data around, which can cause I/O operations to take longer, leading to increased latency1.If the working set size (WSS) exceeds the SSD tier capacity, ILM will have to constantly move data between the SSD and HDD tiers to accommodate new data. This constant data movement can lead to increased I/O latency1.Therefore, if curator scans caused by ILM are constantly moving data, it could be the reason for the observed I/O latency in this scenario.References:* Disk I/O Latency on a Nutanix Cluster | Nutanix Community* Nutanix Volumes – Recommendations And Best Practices* Nutanix Support & Insights* Expand Cluster with Nodes with Higher NIC SPEED (25 GBPS) | Nutanix …* [Scaling Up VM Storage Performance on AHV – Volume Group … – Nutanix]* [About support for Nutanix segmented iSCSI network | Managing AHV …]Q116. An administrator is implementing a VDI solution. The workload will be a series of persistent desktops in a dedicated storage container withina four-node cluster. Storage optimizations should be set on the dedicated storage container to give optimal performance including during a node failure event.Which storage optimizations should the administrator set to meet the requirements?
 Compression, Deduplication, and Erasure Coding
 Deduplication and Erasure Coding
 Compression and Deduplication
 Compression only
ExplanationRef:Q117. A consultant is preparing to add new nodes into an existing cluster. The current cluster AOS version is 5.8.The new expansion node is currently running AOS 5.9 code. The cluster must continue to run at its current AOS version.Which method can be used to successfully add the node?
 Upgrade the cluster to 5.9 and add the node through Prism Element.
 Use Prism Element to Expand the cluster and select the re-image option.
 Use the CLI and enter cluster add-node node-serial=”node_serial”.
 Use Prism Element, which will downgrade the node by default during the node add process.
Q118. A consultant has deployed a Nutanix cluster with AOS 5.10.x, then discovers the customer’s environment is running on AOS 5.6.x. The consultant decides to re-image the cluster using the foundation Java applet. During the Foundation discovery, all cluster nodes display a status of Unavailable.What should the consultant do to resolve the issue?
 Use the Phoenix ISO
 Destroy the cluster.
 Restart the Genesis service on the cluster.
 Reset the IPMI IP addresses.
When a Nutanix cluster needs to be re-imaged and nodes are showing as ‘Unavailable’ during the discovery process in the Foundation tool, it is often due to a deeper issue with the nodes’ existing configuration or software state. Using the Phoenix ISO to re-image the nodes is the recommended approach. The Phoenix ISO can be used to completely reinstall the software on the nodes, ensuring that any problematic configurations or software issues are wiped clean, allowing for a fresh installation with the desired version of AOS.References:* Nutanix Bible: Re-imaging Clusters* Nutanix University: Troubleshooting Installation IssuesQ119. Refer to the exhibit.An administrator has an existing cluster and needs to improve performance using AHV Turbo. Which two items are required to achieve even greater performance? (Choose two.)
 Workloads are multi-threaded.
 VMs have one vCPU configured.
 VMs have multi-queue disabled.
 VMs have more than one vCPU.
To maximize the performance benefits of AHV Turbo, which is designed to optimize network and storage I/O operations for VMs, certain VM configurations are advantageous. The correct answers are:Option A, “Workloads are multi-threaded.” Multi-threaded applications can better utilize the improvements in I/O processing efficiency provided by AHV Turbo, leading to better overall performance.Option D, “VMs have more than one vCPU.” This configuration allows VMs to handle multiple processes or threads simultaneously, which is particularly beneficial when combined with AHV Turbo’s enhanced I/O operations.References:The benefits of configuring VMs with multiple vCPUs and supporting multi-threaded applications are discussed in Nutanix’s documentation on AHV and performance optimization, where AHV Turbo is highlighted for its ability to accelerate VM operations in a Nutanix environment.Q120. An administrator is concerned that Prism will be inaccessible if Active Directory is unable to process logins.Which method should the administrator use to access the cluster in the event of this type of outage?
 Manage the cluster by using the “nutanix” user on the Prism leader CVM
 Create and use an emergency local account on the cluster
 Deploy an Active Directory server locally on the cluster
 Manage the cluster remotely by downloading ncli to a remote workstation
Q121. A consultant is using a customer’s switch for installation. Although the 10GbE ports for each of the hosts are connected to the switch, the nodes fail to be discovered.What is causing the issue?
 IPv6 is not enabled on the switch.
 IPMI port is not plugged in.
 Foundation VM is running on a Windows host.
 10GbE ports are configured with the incorrect duplex setting.
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.References:* Nutanix Foundation Troubleshooting Guide: Nutanix Support Portal* Network Configuration and Troubleshooting DocumentationQ122. A consultant is completing final network failover testing on a recently deployed AHV cluster.The cluster consists of the following:*Three nodes*Two uplinks connected to two switches*Supported SFPsThe consultant removed one SFP+ out of each node. Two of the nodes (Hostl I Host2) failed over to the backup NIC correctly without any interruption but have lost communication with the third node (Host 3) hypervisor/CVM. Inserting the original SFP+ back into the problematic node allowed the network to be connected and the two healthy nodes could communicate successfully again.manage_ovs showjnterfaces outputmanage_ovs showjinterfaces output:name mode link speedcthO 10000 True 10000ethl 10000 False Noneeth2 10000 True 10000eth3 10000 False Nonemanage_ovs show.uplinks output:Bridge: brOBond: brO-upbond_mode: active-backupinterfaces: ethl ethOlacp: offlacp-fa I 1 back: falselacp_speed: slowWhat should the consultant validate first?
 Validate NIC card on node is seated properly.
 Validate that the correct interfaces are included in the bridge.
 Validate the customer has configured all their switch ports identically.
 Validate the SFP+ is fully plugged into the node and switch.
Given the symptoms where two nodes correctly failover but lose communication with the third node after an SFP+ is removed, the first action should be to:* Validate the SFP+ is fully plugged into the node and switch: This is critical because a loose or partially connected SFP+ can cause intermittent network issues, which seems to be the problem based on the scenario described.References:* Nutanix Bible (https://www.nutanixbible.com), particularly the network troubleshooting sections.* Nutanix Field Installation Guide, which provides detailed steps on how to ensure hardware components like SFPs are correctly installed.Q123. A consultant asks a customer to verify the ToR Switch data port configuration was done according to Nutanix best practices. The switch configuration must simplify future deployments and expansions.Which two configuration actions will satisfy this requirement? (Choose two.)
 Disable multicast and broadcast flood optimizations.
 Configure the CVM and hypervisor host VLAN as the native.
 Use a tagged VLAN for the CVM and hypervisor hosts.
 Configure the connected switch ports as access.
For a Nutanix cluster configuration that simplifies future deployments and expansions, disabling multicast and broadcast flood optimizations (A) and using a tagged VLAN for the CVM and hypervisor hosts (C) are the best practices. Disabling these optimizations helps in reducing unnecessary network traffic and potential broadcast storms in a growing environment. Using tagged VLANs for CVM and hypervisor hosts ensures proper network segmentation and scalability, allowing for easier management and expansion without reconfiguring the native network setup for each expansion or deployment.References: Nutanix Network Configuration Best Practices, Nutanix Deployment Guide.Q124. A consultant is deploying a two-node cluster at a remote branch office.Which component must be available to complete cluster configuration?
 Prism Central
 Witness VM
 Remote Site
 Protection Domain
In the deployment of a two-node cluster at a remote branch office, the presence of a Witness VM is essential to manage the cluster quorum and data integrity in case one of the nodes fails or becomes unreachable. The Witness VM acts as an external arbitrator that helps prevent data unavailability and split-brain scenarios in a situation where the cluster nodes cannot communicate with each other. This configuration is necessary because with only two nodes, there isn’t a third node to maintain quorum natively.References: Nutanix Bible, Nutanix UniversityQ125. A consultant configures a Nutanix cluster and integrates the hosts into vCenter using VMware best practices.The customer has requested that the Nutanix cluster only have a single datastore.Upon configuring the cluster per the customer requirements, vCenter displays an alert regarding the heartbeat datastore. The consultant adds the das.ignoreInsufficientHbDatastore value = true rule. The container can be seen from each host, but the alert remains active.What should the consultant do to resolve this issue?
 Turn off and then turn back on HA.
 Make sure the DRS setting is turned on.
 Create a second container.
 Whitelist the vCenter IP address within Prism.
The alert regarding the heartbeat datastore in vCenter, despite setting das.ignoreInsufficientHbDatastore to true, suggests that HA has not acknowledged the updated configuration. The effective solution is to restart HA on the cluster, which involves turning off HA and then turning it back on. This reset will allow vCenter to re-evaluate the datastore configuration and recognize that the insufficient heartbeat datastore alert should be suppressed as per the updated setting.References:* VMware Documentation on HA Configuration: VMware Support* Nutanix and VMware Integration Guide: Nutanix DocumentationQ126. During the knowledge transfer on Prism GUI, a customer asked about AHV best practices for VM High Availability on a five-node cluster and the safest configuration. The consultant informed the customer that best practices dictate that all storage containers are configured with a replication factor of 3.What will be the behavior if the non-default Guarantee mode is selected on Prism with two AHV host failures?
 Keeping the default mode will ensure that all VMs can restart in case of two AHV host failures.
 Keeping the default mode will ensure that all VMs can restart in case of an AHV host failure.
 Will ensure that all VMs can restart if two AHV nodes remains online.
 Will ensure that all VMs can restart in case of two simultaneous AHV host failures.
In a five-node cluster with storage containers configured with a replication factor of 3, the behavior of VM High Availability when two AHV host failures occur with the non-default “Guarantee mode” enabled is as follows:* Will ensure that all VMs can restart in case of two simultaneous AHV host failures: This mode prioritizes maintaining VM availability by reserving enough resources to restart VMs even with multiple host failures, as long as at least three hosts (matching the replication factor) remain functional.References:* Nutanix Bible (https://www.nutanixbible.com), specifically sections on VM High Availability and replication factors.* Nutanix University: NCS-Core 6.8 Training (https://university.nutanix.com), where best practices for VM High Availability are detailed.Q127. A consultant is using the Foundation applet to create a cluster. During the process the consultant refreshes the progress bar web page and is concerned when nothing loads.What should the consultant do to verify that Foundation has completed successfully?
 Return to the Foundation configuration page and start over.
 Update Java on the Foundation VM.
 Connect to any CVM IP address from a web browser.
 Restart the Foundation process.
Q128. 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?
 The VM’s iSCSI traffic is being routed to the data services IP subnet
 The performance test is generating small block random 10.
 The duster data services IP address is a bottleneck, shared with other iSCSI traffic
 Data Locality ensures that VM attached disks are always faster than iSCSI volumes.
Q129. For a new AHV cluster installation, a customer has 20 NX-8155 nodes with quad port NICs. The customer wants to meet the following guidelines:Take advantage of all available 10G linksAchieve maximum throughput per VMUse of redundant ToR switchesFastest reconvergence during link failureHow should the load balancing be configured on the host?
 In Prism Element, update the virtual switch uplink configuration to Active-Active with MAC pinning.
 In Prism Element, update the virtual switch uplink configuration to Active-Active.
 Use CLI to add the interfaces to bridge bro on all hosts.
 Use CLI to configure Balance-TCP on bridge bro.
For a configuration that aims to utilize all available 10G links, achieve maximum throughput per VM, and ensure redundancy with fast reconvergence during link failure, the optimal setting would be to configure Balance-TCP on bridge br0. This setting distributes the load across all available network paths based on the TCP session, maximizing the utilization of network interfaces and ensuring redundancy. This approach is particularly effective in environments with multiple network paths and ensures efficient network traffic management.References:* Nutanix University – NCS-Core 6.8 Learning Path* The Nutanix Bible, Network Configuration chapter (https://www.nutanixbible.com/)Q130. A customer wants to validate the Microsoft SQL workload performance for a CRM application before migration to the new Nutanix cluster.Which activity must the consultant add as part of the test plan to fulfill this requirement?
 X-Ray with OLAP Workload.
 Run perfmon on guest VM.
 X-Ray with OLTP Workload.
 Run perfmon on all CVMs.
To validate the performance of a Microsoft SQL workload for a CRM application, using X-Ray with an OLTP (Online Transaction Processing) Workload is most suitable. OLTP workloads simulate typical transactional database operations which are representative of CRM application usage, providing accurate insights into expected performance on the Nutanix platform.References:* Nutanix Bible (https://www.nutanixbible.com), specifically the sections on performance testing tools and methodologies.* Nutanix University: NCS-Core 6.8 Training (https://university.nutanix.com), detailing how to use X-Ray for specific application testing.Q131. An administrator receives a notification that storage in a Nutanix cluster is unavailable. The cluster consists of five nodes and is configured with a Fault-Tolerance level of 1 (FT-1).Upon investigation, the administrator finds the following:* All AHV hosts are powered on and the CVMs are running* Nodes A, B, and C are connected to one top of rack switch* Nodes D and E are connected to a second top of rack switch* The cluster status command run on Node A shows that CVM services on nodes D and E are down Which issue is causing the storage outage?
 The default gateway for the CVMs and AHV hosts is down.
 The switch connecting Nodes D and E is down.
 The genesis process is down on both Nodes D and E.
 Nodes D and E are inmaintenance mode.
