NEW QUESTION # 74
An administrator wants to replace and old node with a node of newer generation in a 3-node cluster. The administrator has already chosen the appropriate node. But unable to remove it from the cluster.
Why is the Remove Host option not shown in the exhibit?
- A. It is not possible to remove a host from a 3-node cluster.
- B. It is not possible to remove a node from a the cluster using Prism Central
- C. It is only possible to remove a host from a cluster using CLI.
- D. The host needs to be placed into maintenance Mode before.
Answer: A
Explanation:
A Nutanix cluster requires a minimum of three nodes to maintain quorum and data availability. Removing a node from a 3-node cluster would violate the redundancy factor and cause data loss. Therefore, it is not possible to remove a host from a 3-node cluster using Prism or CLI. The only way to replace a node in a
3-node cluster is to use the Foundation tool, which will erase the existing cluster configuration and create a new cluster with the new node1.

NEW QUESTION # 76
An administrator manages a cluster and notices several failed components shown in the exhibit.
What two options does the administrator have to run all NCC checks manually? (Choose two.)
- A. Running noc health_checks run_all on the PC VM
- B. Using the action action drop-down menu in the Health dashboard of Prism Central
- C. Running ncc health_checks run-alll on the CVM
- D. Using the Actions drop-down menu in the Health dashboard of Prism Element.
Answer: C,D
Explanation:
Prism Element and NCC are two ways to run all NCC checks manually on a Nutanix cluster. Prism Element is the web console that provides management and monitoring capabilities for a single Nutanix cluster. Prism Element has a Health dashboard that shows the status of various components and services in the cluster, such as disks, nodes, CVMs, NCC, and alerts. The Health dashboard also allows the administrator to run NCC checks manually by using the Actions drop-down menu on the right side of the screen. The administrator can choose to run all NCC checks or specific checks based on the category or severity. The NCC checks will run in the background and generate a report that can be viewed or downloaded from the Summary tab. This method is easier and faster than running NCC from the command line on the CVM.
NCC stands for Nutanix Cluster Check, which is a framework of scripts that performs system checks and validations on Nutanix clusters. NCC can detect issues related to hardware, software, configuration, hypervisor, networking, and more. NCC can be run from the command line interface (CLI) of any CVM in the cluster by using the ncc command. To run all NCC checks manually, the administrator can use the command ncc health_checks run_all, which will execute all available checks and display the results on the screen. This method is more comprehensive and detailed than running NCC from Prism Element.

NEW QUESTION # 81
Administrator is creating a Windows 10 VM that will be used for a virtual desktop template. After creating the VM and booting to the ISO, the administrator is unable to install Windows and receives the following error.
What steps does the administrator need to take to install the OS?
- A. Load the Virtual SCSI pass-through controller.
- B. Load the Nutanix VirtIO Serial Bus Driver.
- C. Load the Nutanix Virtual Balloon Driver.
- D. Load the VirtIO Network Ethernet Adaper.
Answer: A
Explanation:
answer: D. Load the Virtual SCSI pass-through controller.
The error message shown in the image indicates that Windows 10 setup cannot find any drives to install the OS. This is because the Nutanix AHV hypervisor uses a virtual SCSI pass-through controller to present disks to the VMs, and Windows 10 does not have a built-in driver for this device. Therefore, the administrator needs to load the Nutanix VirtIO driver for the virtual SCSI pass-through controller during the OS installation process.The Nutanix VirtIO driver package contains various drivers that are specifically used by Windows VMs hosted in the Nutanixenvironment to enhance their stability and performance1. The administrator can download the latest Nutanix VirtIO driver package from theVirtIO downloads pageof the Nutanix support portal.The administrator can then follow these steps to load the driver and install the OS2:
* On the Windows 10 setup screen, click Load driver.
* Insert a USB drive or mount an ISO image that contains the Nutanix VirtIO driver package.
* Browse to the location of the driver package and select the folder that matches the OS architecture (32-bit or 64-bit).
* Select the vioscsi.inf file and click Next.
* Wait for the driver to load and then click Refresh.
* Select the disk where you want to install Windows 10 and click Next.

Which component can be associated with a storage policy?
- A. Vm
- B. Category
- C. Catalog
- D. Subnet
Answer: A
Explanation:
A storage policy can be associated with a VM. A storage policy is a set of rules that define how data objects are stored and protected. It specifies the characteristics of storage, data protection, and data placement for virtual disks that are assigned to a VM. Subnets, catalogs, and categories are not associated with storage policies.https://portal.nutanix.com/page/documents/details?targetId=Prism-Central-Guide-vpc_2022_6:mul-clust
NEW QUESTION # 84
When a VM is connected to a Nutanix managed network, when is the IP addressed assigned?
- A. When the guest OS sends a DHCP request.
- B. When the VM is powered on.
- C. When the guest OS receives a DHCP acknowledge.
- D. When the vNIC is created on the VM.
Answer: B
Explanation:
When a VM is connected to a Nutanix managed network, the IP address is assigned when the VM is powered on. A Nutanix managed network is a network that is created and managed by Prism Central using IP address management (IPAM). IPAM allows Prism Central to automatically assign IP addresses to VMs from a pool of available addresses in a subnet. IPAM also tracks the IP address usage and availability across clusters and networks4.
When a VM is connected to a Nutanix managed network, the administrator can choose one of the following assignment types for the IP address:
* Assign Static IP: This option allows the administrator to manually specify a static IP address for the VM from the subnet range. The IP address will not change unless the administrator changes it.
* Assign with DHCP: This option allows Prism Central to dynamically assign an IP address for the VM from the subnet range using DHCP. The IP address may change depending on the DHCP lease time and availability.
* No Private IP: This option allows the administrator to skip assigning an IP address for the VM. This option is useful for scenarios where the administrator wants to use an external IPAM solution or assign an IP address later5.
Regardless of the assignment type, the IP address is assigned when the VM is powered on. This is because Prism Central needs to communicate with the hypervisor (AHV or ESXi) to configure the virtual NIC (vNIC) of the VM with the IP address information. This communication can only happen when the VM is in a powered on state6.

NEW QUESTION # 85
An administrator has created a Nutanix managed it a VLAN ID of 512.
Several VMs have been created, and the administrator notices that the can successfully communicate with other VMs on that VLAN.
Provided they are on the host, but cannot communicate with VMs that reside on different hosts in the cluster.
What is most likely thee cause of this issue?
- A. The VLAN was not created on the upstream switches.
- B. There is a firewall rule blockingVLAN512 traffic.
- C. The administrator did not create the VLAN on all hosts
- D. VLANS12 is a reserved VLAN ID, and not usable for guest VMs.
Answer: A
Explanation:
The correct answer is C. The VLAN was not created on the upstream switches.
A VLAN (virtual local area network) is a logical segmentation of a physical network that allows devices on the same VLAN to communicate with each other, regardless of their physical location. A VLAN also isolates the devices on different VLANs from each other, unless there is a router or a layer 3 switch that can route traffic between VLANs. To create a VLAN, the administrator needs to configure the network devices that are involved in the VLAN, such as switches, routers, and hosts. The administrator also needs to assign a unique VLAN ID to each VLAN, which is a number between 1 and 4094 that identifies the VLAN1.
In Nutanix AHV, the administrator can create a Nutanix managed network with a specific VLAN ID for guest VMs. This network can be assigned to VM NICs using Prism Element or Prism Central. However, creating a Nutanix managed network does not automatically create the VLAN on the upstream switches that connect the AHV hosts. The administrator needs to manually configure the upstream switches to allow the VLAN traffic on the ports that connect to the AHV hosts. The administrator also needs to ensure that the upstream switches are interconnected physically or virtually and can forward traffic between different VLANs if needed2.
Therefore, if an administrator has created a Nutanix managed network with a VLAN ID of 512 and notices that the VMs on that network can only communicate with other VMs on the same host, but not with VMs on different hosts in the cluster, the most likely cause of this issue is that the VLAN was not created on the upstream switches. This means that the switches are dropping or blocking the traffic with VLAN ID 512 and preventing it from reaching other hosts or VMs. To resolve this issue, the administrator should create the VLAN on the upstream switches and allow it on the ports that connect to the AHV hosts3.
NEW QUESTION # 86
Refer to the exhibit.
An administrator is trying to implement the solution that is shown in the exhibit, but has been unsuccessful.
Based on the diagram, what is causing the issue?
- A. Active containers in both sites
- B. Network latency
- C. Unsupported hypervisor
- D. A remote Witness VM
Answer: B
Explanation:
The correct answer is C. Network latency.
The diagram shows a solution that uses synchronous replication between two remote protection domains, cluster site A and cluster site B. Synchronous replication is a feature that allows near-zero RPO (recovery point objective) by replicating data to the remote site before acknowledging writes to the local site. However, synchronous replication has some requirements and limitations that must be met for it to work properly. One of these requirements is that the network latency between the two sites must be less than or equal to 5 ms1. If the network latency is higher than 5 ms, the synchronous replication will fail and the protection policy will be suspended2.
Therefore, based on the diagram, the most likely cause of the issue is that the network latency between cluster site A and cluster site B is higher than 5 ms, which prevents the synchronous replication from working. To verify this, the administrator can use the "ncli cluster ping" command to measure the network latency between the two sites3. If the network latency is indeed higher than 5 ms, the administrator can either improve the network performance or switch to a different replication mode, such as near-synchronous or asynchronous.
NEW QUESTION # 87
Which inefficient VM Profile can be used to identify a VM that consumes too many resources and causes other VMs to starve?
- A. Constrained VM
- B. Inactive VM
- C. Bully VM
- D. Over-provisioned VM
Answer: C
Explanation:
A bully VM is a VM that consumes too many resources and causes other VMs to starve. A bully VM can affect the performance and availability of other VMs on the same host or cluster by hogging CPU, memory, disk, or network resources. A bully VM can be identified by using the VM Profile feature in Prism Central2. The VM Profile feature analyzes the resource utilization of each VM and assigns it a profile based on its efficiency and impact on other VMs. The profiles are as follows3:
Efficient: The VM is well-provisioned and has optimal resource utilization.
Over-provisioned: The VM has more resources than it needs and has low resource utilization.
Constrained: The VM has less resources than it needs and has high resource utilization.
Inactive: The VM has no resource utilization and is idle or powered off.
Bully: The VM has high resource utilization and causes contention for other VMs.
To identify a bully VM, the administrator can use Prism Central to view the VM Profile dashboard and filter by profile type. The dashboard shows the number of VMs in each profile type, as well as their resource consumption and efficiency score. The administrator can also drill down into each VM to see its detailed metrics and recommendations for optimization.
NEW QUESTION # 88
An administrator is commissioning a Nutanix Enterprise Cloud. Once the user VMs have been deployed and are running, the administrator finds that VMs on the same host are able to communicate, but are unable to communicate between hosts.
What must be changed to enable full inter-VM communications?
- A. The VMs need to have static IP addresses.
- B. Change the network the VMs are connected to
- C. Update the switch to specifically allow VLAN 15
- D. Change the spanning-tree port type on the switch.
Answer: C
Explanation:
According to the web search results, one possible cause of inter-VM communication failure between hosts is that the switch is not configured to allow VLAN 15 traffic. VLAN 15 is the default VLAN ID used by AHV for internal communication between CVMs and hosts. If the switch blocks or drops VLAN 15 packets, it will prevent inter-VM communication across hosts4. To enable full inter-VM communication, the administrator should update the switch to specifically allow VLAN 15 traffic on the ports connected to the AHV hosts.

NEW QUESTION # 90
An administrator manages an AHV cluster that is dedicated to a dev/test environment. The administrator receiving complaints from users that they are unable to create new VMs on the cluster.
After the reviewing the cluster, the administrator finds that the memory resources are almost fully utilized, with many VMs over-provisioned on memory.
What option is the most efficient resolution to enable additional VMs to be created?
- A. Enable Memory HA on the over-provisioned VMs.
- B. Disable HA Reservation on the cluster.
- C. Upgrade the nodes with additional memory DlMMs.
- D. Enable Memory Overcommit on the over-provisioned VMs.
Answer: D
Explanation:
Enable Memory Overcommit on the over-provisioned VMs is the most efficient resolution to enable additional VMs to be created. Memory overcommit allows VMs to use more memory than physically available on a host by compressing and swapping memory pages to storage1. This can improve memory utilization and increase VM density on a cluster1. However, memory overcommit is not supported when HA is configured to use reserved hosts, so you may need to disable HA reservation on the cluster before enabling memory overcommit

NEW QUESTION # 94
Which two predefined views can be added to a report to identify inefficient VMs?
- A. Overprovisioned VMs List
- B. Constrained VMs List
- C. Underprovisioned VMs List
- D. Zombie VMs List
Answer: A,D
Explanation:
Zombie VMs and overprovisioned VMs are two types of inefficient VMs that can waste resources and increase costs in a Nutanix environment. Zombie VMs are VMs that are powered on but have no activity or utilization for a long period of time. Overprovisioned VMs are VMs that have more resources allocated than they actually need or use. Both types of VMs can be identified by adding predefined views to a report in Prism Central.
A predefined view is a template that defines what data is displayed and how that data is represented in a report. Prism Central provides several predefined views for different purposes, such as capacity planning, performance analysis, anomaly detection, and efficiency optimization. To add a predefined view to a report, go to Operations > Reports > New Report and select the desired view from the list1.
The Zombie VMs List view shows the list of zombie VMs in the environment based on the CPU usage, memory usage, disk IOPS, and network throughput metrics. The view also shows the amount of resources wasted by these VMs and the potential savings that can be achieved by deleting or resizing them2.
The Overprovisioned VMs List view shows the list of overprovisioned VMs in the environment based on the CPU usage, memory usage, disk IOPS, and network throughput metrics. The view also shows the amount of resources wasted by these VMs and the potential savings that can be achieved by resizing them3.
By adding these two views to a report, an administrator can identify inefficient VMs and take appropriate actions to optimize resource utilization and reduce costs.
NEW QUESTION # 95
