NEW QUESTION # 11
Which three cluster operations require an administrator to reclaim licenses?(Choose three)
- A. Destroy a cluster.
- B. Migrate a cluster
- C. Remove a Node from a cluster
- D. Upgrade a cluster
- E. Move Nodes between clusters.
Answer: A,C,E
Explanation:
https://portal.nutanix.com/page/documents/details/?targetId=Web_Console_Guide-Prism_v4_7:lic_licensing_ma Reclaiming Licenses (Including License Renewal) You can reclaim and optionally re-apply licenses for nodes in your clusters:
* You must reclaim licenses when you plan to destroy a cluster. First reclaim the licenses, then destroy the cluster. You do not need to reclaim Starter licenses. These licenses are automatically applied whenever you create a cluster, including after you have destroyed a cluster.
* Return licenses to your inventory when you remove one or more nodes from a cluster. Also, if you move nodes from one cluster to another, first reclaim the licenses, move the nodes, then re-apply the licenses.
* You can reclaim licenses for nodes in your clusters in cases where you want to make modifications or downgrade licenses. For example, applying an Ultimate license to all nodes in a cluster where some nodes are currently licensed as Pro and some nodes are licensed as Ultimate. You might also want to transition nodes from Ultimate to Pro licensing.
* You must reclaim licenses when you renew licenses. First reclaim the expired licenses, then apply new licenses.

- D. Cluster CPU and Memory Only
Answer: C
NEW QUESTION # 13
The Stargate service becomes unavailable on a single CVM on an AHV node. What is used to maintain I/O operations in the cluster?
- A. ha.py
- B. Hypervisor HA
- C. Route injection
- D. iSCSl redirector
Answer: C
Explanation:
According to the Nutanix Support & Insights web search result1, route injection is used to maintain I/O operations in the cluster when the Stargate service becomes unavailable on a single CVM on an AHV node. Route injection is a mechanism that allows the CVMs to communicate with each other and redirect the I/O requests to another healthy CVM in the cluster. Route injection uses the Linux kernel routing table to add or delete routes dynamically, based on the availability of the Stargate service on each CVM.
NEW QUESTION # 14
Refer to Exhibit:
An administrator is trying to put a node into maintenance mode but receives the message shown in the exhibit.
What is a potential reason for this dialog?
- A. LinuxVM1 uses e vDisks stored in a RF3 Datastore
- B. LinuxVM1 uses a virtual GPU.
- C. LinuxVM1 uses a vDisks stored in a RF1 Datastore
- D. LinuxVM1 uses a Volume Group
Answer: C
Explanation:
According to the Nutanix Community1, host maintenance mode is used to safely migrate all the user virtual machines (VMs) in the host and make sure no VMs are running on the node. If a VM can't be migrated to another host, you need to shut down the VM for the host to enter into maintenance mode.
According to The Virtualist2, a storage container is a logical segmentation of a storage pool that can be mounted as an NFS datastore on ESXi hosts. You can choose a replication factor (RF) for each storage container, which determines how many copies of data are stored across different nodes.
NEW QUESTION # 15
What is a requirement to enable Flow Neworking?
- A. A dedicated virtual switch has been created for Flow Networking.
- B. Prims Central is using a three-node scale-out deployment
- C. Flow Micro segmentation must be enabled.
- D. Microservices infrastructure must be enabled.
Answer: D
Explanation:
Flow Networking is a feature that enables software-defined networking for AHV clusters. It allows users to create and manage virtual private clouds (VPCs), subnets, and network services such as NAT, DHCP, routing, and VPN. Flow Networking also supports service insertion and chaining, which enables integration with third-party network functions such as firewalls and load balancers. Flow Networking is built on top of the microservices infrastructure (MSP) in Prism Central, which provides the platform for running various Nutanix services such as Calm, Karbon, and Objects. Therefore, to enable Flow Networking, the MSP must be enabled first on Prism Central1. The MSP can be enabled from the Prism Central settings page or from the command line interface (CLI) of the Prism Central VM2. Enabling the MSP will also enable Flow Microsegmentation, which is another feature that provides network security and visibility for AHV clusters.
NEW QUESTION # 16
Refer to Exhibit:
An administrator is attempting to create an additional virtual switch on a newly deployed AHV cluster, using the two currently disconnected interfaces. The administrator is unable to select the disconnected interfaces when creating the virtual switch.
What is the likely cause of this issue?
- A. Interfaces must be connected to the network before they can be assigned.
- B. The disconnected interfaces are currently assigned to virtual switch 0,
- C. Interfaces must be assigned to virtual switches via the cli
- D. Only one interface is available on the selected hosts.
Answer: A
Explanation:
In Nutanix AHV, when creating a virtual switch and trying to add network interfaces (NICs) to it, the NICs must be connected to the network before they can be selected and assigned to the switch. If the interfaces are showing as disconnected, the system will not allow them to be added to a virtual switch because it cannot verify their operational status or the presence of a live network connection.
It is a standard requirement for the interfaces to have physical connectivity (i.e., network cables plugged in and connected to a live switch port) so that the AHV host can detect the link status as up. Once the interfaces are connected and recognized by the host, they can then be added to a virtual switch in the Nutanix AHV.
It's important to note that while the command-line interface (CLI) is indeed a powerful tool for managing network configurations on AHV hosts, and some configurations do indeed require CLI, the inability to select disconnected interfaces is not specifically a limitation that requires the use of CLI to overcome. The focus should be on ensuring that the physical connectivity is established for the interfaces in question.
This behavior is consistent with networking best practices and Nutanix's network configuration guidelines, as detailed in the Nutanix AHV Networking Guide. This guide explains the requirements and procedures for configuring virtual switches and managing NICs in a Nutanix AHV environment.
NEW QUESTION # 17
What are two minimum prerequisites for live migration to succeed? (Choose two.)
- A. All VMs are configured for the same VLAN
- B. All VMs have an IP address in the same subnet
- C. All AHV hosts have IP addresses in the same subnet
- D. All AHV hosts must be configured on the same VLAN
Answer: C,D
NEW QUESTION # 18
Refer to the exhibit.
Which two initial cluster configuration tasks were missed during the deployment process? (Choose two.)
- A. Password policy changes
- B. BIOS password changes
- C. CVM password changes
- D. Host password changes
Answer: C,D
Explanation:
According to the image description, the exhibit shows a screenshot of a computer screen with a table of data.
The table has 6 columns and 4 rows. The columns are labeled "Date", "Time", "Status", "Details",
"Configuration", and "Duration". The rows contain information about different configurations and their statuses. The background is a light blue color. There is a pop-up message on the bottom right corner of the screen that reads "This question has been answered. Click here to enable the edit button." Based on the table data, it seems that the screenshot is taken from the Prism Central web console, showing the results of a cluster health check report. The report shows that there are four failed checks: Host Password Policy, CVM Password Policy, NTP Configuration, and Cluster Time Skew2. These checks indicate that some initial cluster configuration tasks were missed during the deployment process.
The Host Password Policy check verifies that the host passwords are not set to default values and are compliant with the password policy defined in Prism Central3. The CVM Password Policy check verifies that the CVM passwords are not set to default values and are compliant with the password policy defined in Prism Central4. These checks are important for ensuring the security and compliance of the cluster. Therefore, changing the host and CVM passwords from their default values and following the password policy guidelines are two initial cluster configuration tasks that were missed.

NEW QUESTION # 21
After running an LCM inventory it is noticed that there are a number of firmware and software updates available. The administrator would like to avoid any host reboots, but would like to apply some of the available updates?
Which two updates can be done while avoiding a host reboot? (Choose two.)
- A. M.2 Drives
- B. AOS
- C. AHV
- D. Data Drives
Answer: B,D
NEW QUESTION # 22
What is the expected behavior of the VMs residing on that host when a controller VM becomes unavailable?
- A. The host will automatically redirect I/O and VMs will continue running.
- B. VM High Availability will restart the impacted VMs on another host
- C. A Live Migration will be performed on the affected VMs.
- D. The impacted host and VMs will automatically shut down.
Answer: A
Explanation:
According to the Nutanix Support & Insights web search result1, if the owner Controller VM becomes unavailable, the address moves to another Controller VM, ensuring that it is always available. This IP address is also used as a cluster-wide address by clients configured as part of Nutanix Files and other products. Therefore, the host will automatically redirect I/O and VMs will continue running without any interruption.
NEW QUESTION # 23
A customer has a 24-node cluster with all containers configured with RF3. Two different nodes have incurred a simultaneous HDD failure.
What is the result?
- A. The VMs with data on those drives crash, and an HA event occurs, restarting them on a remaining healthy node.
- B. Sixty minutes after the failures a rebuild of the lost data can remaining HDDs begins to restore to three replicas.
- C. The Nutanix cluster recognizes the failures and immediately begins to rebuild lost data to three replicas.
- D. The cluster runs in a degraded state until the failed drives are replaced and the data has been restored to three replicas.
Answer: C
Explanation:
This is because Nutanix uses a distributed storage fabric (DSF) that replicates data across multiple nodes and drives to ensure data resiliency. When a drive fails, the cluster detects the failure and initiates a data rebuild process to restore the replication factor (RF) of the affected containers. The data rebuild process does not affect the availability or performance of the VMs, as they can still access their data from other replicas on other nodes or drives. Therefore, there is no need to wait for 60 minutes, use a shared volume group, or trigger an HA event.
NEW QUESTION # 24
When installing Nutanix Guest Tools (NGT) on an ESXi-hosted VM, which port should be enabled on the VM to allow communication with the NGT-Controller VM service?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: B
Explanation:
NGT is a software package that enables advanced VM management features provided by Nutanix, such as file-level restore, VM mobility, and application-consistent snapshots12. To use NGT, you need to enable the NGT feature for a VM in the Prism Element web console, mount the NGT installer (ISO disk file) in the VM, and install NGT in the VM1. However, before installing NGT, you need to ensure that the VM can communicate with the NGT-Controller VM service, which runs on the Controller VM (CVM) of each Nutanix node3. The NGT-Controller VM service listens on port 9943 for incoming requests from the guest VMs3.
Therefore, you need to enable port 9943 on the ESXi-hosted VM to allow communication with the NGT-Controller VM service.
NEW QUESTION # 25

NEW QUESTION # 27
An administrator is setting up a Nutanix cluster and needs to configure the default VLAN.
Which configuration should the administrator choose?
- A. Vlan.2
- B. Vlan.7
- C. Vlan.1
- D. Vlan.0
Answer: C
Explanation:
Nutanix cluster is a group of Nutanix nodes that share data and resources across a network1. A VLAN is a virtual LAN that allows devices on different physical LANs to communicate as if they were on the same network2.
by default, a virtual NIC (VM NIC) on a guest VM operates in access mode and can send and receive traffic only over its own specified VLAN. The default VLAN ID for access mode interfaces is 1.
Therefore, by choosing Vlan.1 as the default VLAN, you can simplify the network configuration and avoid potential issues with other VLAN IDs.
NEW QUESTION # 28
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. There is a firewall rule blockingVLAN512 traffic.
- B. VLAN512 is a reserved VLAN ID, and not usable for guest VMs.
- C. The VLAN was not created on the upstream switches.
Answer: C
NEW QUESTION # 29
An administrator needs to relocate an AHV cluster to a new datacenter during a maintenance window. The cluster will use the same IPs in the new datacenter.
Which two steps should be taken to prepare for this task? (Choose two.)
- A. Shut down all user VMs in the cluster
- B. Stop all Nutanix Files clusters
- C. Reconfigure IPMI for the new datacenter
- D. Relocate the linked LDAP server
Answer: A,B
Explanation:
According to the web search results, two steps that should be taken to prepare for relocating an AHV cluster to a new datacenter during a maintenance window are:
Shut down all user VMs in the cluster: This step is necessary to ensure that there is no data loss or corruption during the relocation process. The user VMs can be shut down either individually or in bulk by using the Prism Element web console or the acli command-line interface1.
Stop all Nutanix Files clusters: If the AHV cluster hosts any Nutanix Files clusters, they should be stopped before relocating the cluster. Nutanix Files clusters are composed of one or more virtual machines that provide file services to clients. Stopping a Nutanix Files cluster will stop all the file server VMs and release the resources they consume2. The Nutanix Files clusters can be stopped by using the Prism Element web console or the ncli command-line interface3.
NEW QUESTION # 30
Which scenario would benefit most from Erasure Coding being enabled on a container?
- A. VDI use cases where a single VM is cloned 100's of times
- B. Long term storage of data which is written once and read infrequently
- C. WEB and API Servers
- D. High performance database where all is relatively hot.
Answer: B
Explanation:
The correct answer is A. Long term storage of data which is written once and read infrequently.
Erasure Coding is a feature that increases the usable capacity on a Nutanix cluster by reducing the amount of data replication. Instead of replicating data, Erasure Coding uses parity information to rebuild data in the event of a disk failure. The capacity savings of Erasure Coding is in addition to deduplication and compression savings1.
Erasure Coding is most beneficial for scenarios where the data is written once and read infrequently, such as long term storage of archival data, backup data, or cold data. This is because Erasure Coding has some trade-offs and limitations that may affect the performance and availability of the cluster. Some of these trade-offs and limitations are2:
Erasure Coding requires more CPU and memory resources than replication, as it involves more complex calculations for encoding and decoding data.
Erasure Coding increases the network bandwidth consumption, as it involves more data transfers between nodes for encoding and decoding data.
Erasure Coding reduces the resiliency of the cluster, as it can tolerate fewer node failures than replication. For example, a cluster with redundancy factor 2 can tolerate one node failure with replication, but only two disk failures with Erasure Coding.
Erasure Coding is not effective for workloads that have many overwrites or random writes, as it involves more overhead for updating the parity information.
Erasure Coding is not supported for some features, such as volume groups, file server VMs, or Metro Availability.
Therefore, if an administrator needs to configure a container on a Nutanix cluster, they should enable Erasure Coding only if the container will store data that is written once and read infrequently. This way, they can maximize the capacity savings of Erasure Coding without compromising the performance and availability of the cluster.
NEW QUESTION # 31
An administrator has received reports of users being disconnected from remote desktop sessions to a specific VM.
Which VM metric is most useful isolating the cause of the issue?
- A. Swap-Out Rate
- B. Storage Controller Bandwidth
- C. Hypervisor CPU Ready time (%)
- D. Virtual NIC receive packet dropped
Answer: D
Explanation:
Virtual NIC receive packet dropped is the most useful VM metric for isolating the cause of users being disconnected from remote desktop sessions to a specific VM. This metric shows the number of packets that are dropped by the virtual NIC of the VM due to insufficient buffer space or other reasons. Packet drops can indicate network congestion, misconfiguration, or performance issues that can affect the quality and availability of remote desktop sessions. Packet drops can also cause retransmissions, delays, and errors in TCP-based protocols such as RDP2. To view this metric in Prism, go to Entities > Compute & Storage > VMs
> Summary View andselect a VM. Then, in the Details View, go to Metrics > Performance and select Virtual NIC receive packet dropped from the drop-down menu3.
NEW QUESTION # 32
Which component can be associated with a storage policy?
- A. Subnet
- B. Catalog
- C. Category
- D. Vm
Answer: D
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-cluster-storage-policy-summary-view-pc-r.html
