A vDisk is read by multiple VMs. The cluster creates immutable copies of the vDisk. What are these vDisk copies called?
- A. Disk Clones
- B. Volume Groups
- C. Shadow Clones
- D. Golden Images
Answer: C
Explanation:
According to the Nutanix Support & Insights web search result3, shadow clones are vDisk copies that are created by the cluster when a vDisk is read by multiple VMs. Shadow clones are immutable copies of a vDisk that are stored in different nodes in the cluster, and are used to improve read performance and reduce network traffic. Shadow clones are automatically created and deleted by the cluster, based on the demand and availability of resources.

NEW QUESTION # 59
Refer to Exhibit:
An administrator needs to enable inline deduplication for a pre-existing storage container. When trying to enable deduplication on the storage container. this feature is grayed-out.
What is the reason for this behavior?
- A. The cluster has hybrid storage and deduplication is supported only on all-flash clusters.
- B. The cluster has less than 5 nodes which is the minimum node-count to enable deduplication.
- C. Capacity reservation is not enabled on the storage container.
- D. Replication Factor 1 is configured on the storage container.
Answer: A
Explanation:
Nutanix supports two types of deduplication: post-process and inline. Post-process deduplication runs periodically on a schedule and can be enabled on any cluster. Inline deduplication runs in real time before data is written to disk and can be enabled only on all-flash clusters.
Therefore, by checking the type of storage and the type of deduplication, you can determine if you can enable inline deduplication on a storage container or not.
Nutanix inline deduplication is a feature that reduces the stored size and avoids duplicate data on a storage container1. It is recommended only on some specific scenarios, such as when using Nutanix Files or virtual desktop infrastructure (VDI) workloads12.
NEW QUESTION # 60
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.

What option is the most efficient resolution to enable additional VMs to be created?
- A. Enable Memory Overcommit on the over-provisioned VMs.
- B. Disable HA Reservation on the cluster.
- C. Upgrade the nodes with additional memory DlMMs.
- D. Enable Memory HA on the over-provisioned VMs.
Answer: B
NEW QUESTION # 61
Refer to the exhibit.
An administrator is adding a new node to a cluster. The node has been imaged to the same versions of AHV and AOS that the cluster running, configured with appropriate IP addresses, and br0-up has been configured the same the existing uplink bonds When attempting to add the node to the cluster with the Expand Cluster function in Prism , the cluster is unable to find the new node.
Based on the above output from the new node, what is most likely the cause of this issue?
- A. LACP configuration must be completed after cluster expansion
- B. There is a firewall blocking the discovery traffic from the tlu
- C. The ports on the upstream switch are not configured for LACP.
- D. The existing and the expansion node are on different VLANs.
Answer: D
Explanation:
The correct answer is B. The existing and the expansion node are on different VLANs.
The output shows that the new node has a br0-up bond with four interfaces: eth0, eth1, eth2, and eth3. The bond is configured with LACP active and LACP fallback set to false. This means that the bond will only work if the upstream switch supports LACP and is configured to form an LACP group with the four interfaces. However, the output also shows that the bond has no IP address assigned to it, which indicates that the bond is not operational. One possible reason for this is that the existing and the expansion node are on different VLANs, and the upstream switch is not configured to allow the VLAN traffic on the LACP group. This would prevent the new node from communicating with the cluster and being discovered by the Expand Cluster function in Prism.
To verify this, the administrator can check the VLAN configuration on the upstream switch and compare it with the existing nodes. Alternatively, the administrator can use the "manage_ovs show_uplinks" command on an existing node and compare the output with the new node. If there is a VLAN mismatch, the administrator can either change the VLAN configuration on the switch or on the new node to match the existing nodes.
NEW QUESTION # 62
During an AHV upgrade, an administrator finds that a critical VM was powered off rather than migration to another host.
Which scenario explains this behavior?
- A. The VM was marked as an agent VM.
- B. NO AHV hosts were able to be scheduled.
- C. The VM was on the same host as the acropolis leader.
- D. The VM OS hung during migration.
Answer: A
Explanation:
An agent VM is a special type of VM that is used for running services or applications that are not affected by high availability (HA) events or host maintenance. An agent VM is never migrated to any other host in the cluster. If an HA event occurs or the host is put in maintenance mode, agent VMs are powered off and are powered on on the same host once that host returns to a normal state. This behavior is different from regular VMs, which are migrated to another host in the cluster if possible, or restarted on the same host if not possible1.
Therefore, during an AHV upgrade, an administrator may find that a critical VM was powered off rather than migrated to another host if the VM was marked as an agent VM. This can be done either from the Prism web console by selecting the Use this VM as an agent VM option in the Update VM dialog box, or from the aCLI by using the vm.create or vm.update commands with the agent_vm=true parameter2. To avoid this situation, the administrator should ensure that any critical VMs are not marked as agent VMs before starting the AHV upgrade.
NEW QUESTION # 63

Answer: A,B
NEW QUESTION # 65
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. Interfaces must be assigned to virtual switches via the cli
- C. The disconnected interfaces are currently assigned to virtual switch 0,
- D. Only one interface is available on the selected hosts.
Answer: C
Explanation:
when you create a new virtual switch on AHV, you need to select one or more uplink interfaces that are connected to a physical network. You cannot select an interface that is already assigned to another virtual switch. By default, AHV creates a virtual switch called br0 that uses all available interfaces on the host2. Therefore, if you want to use some of those interfaces for another virtual switch, you need to remove them from br0 first.

NEW QUESTION # 66
A user running a Computer Aided Design (CAD) application is complaining about slow response time within the VM, particular when moving windows or rendering images.
Which VM metric will guide the administrator toward diagnosing the problem?
- A. Swap in Rate
- B. GPU Usage
- C. Storage Controller Latency
- D. Hypervisor Memory Usage (%)
Answer: B
Explanation:
A GPU (graphics processing unit) is a specialized hardware device that can accelerate graphics rendering and computation for applications that use APIs such as DirectX, OpenGL, CUDA, and OpenCL. A GPU can also offload the CPU from encoding and decoding tasks for remote display protocols such as Frame Remote Desktop Protocol (FRP). A VM can use a GPU either by directly accessing a physical GPU (pGPU) on the host or by using a virtual GPU (vGPU) that shares a pGPU with other VMs. A user running a computer aided design (CAD) application may benefit from using a GPU or a vGPU to improve the performance and responsiveness of the application, especially when moving windows or rendering images. However, if the GPU or vGPU is not properly configured or provisioned, the user may experience slow response time within the VM. Therefore, to diagnose the problem, the administrator should monitor the GPU Usage metric for the VM. The GPU Usage metric shows the percentage of GPU resources that are consumed by the VM over time3. The administrator can use Prism Central to view the GPU Usage metric for each VM in a chart or a widget4. The administrator can also use Prism Central to view other metrics related to GPU performance, such as GPU Memory Usage, GPU Encoder Usage, and GPU Decoder Usage3. By analyzing these metrics, the administrator can determine if the VM is using the GPU efficiently and optimally, or if it needs more or less GPU resources.
NEW QUESTION # 67
An administrator logs in to Prism Element goes to the Network view, and sees the output shown in the exhibit.
Which three steps must the administrator take to increase throughput to the host? (Choose three.)
- A. Change the bond mode to balance-slb or balance-tcp.
- B. Connect the 10Gb interfaces to the physical switch.
- C. Add a new switch to the network and connect 1Gb interfaces to it.
- D. Change the VLAN ID to a higher priority ID.
- E. Remove any 1Gb interfaces still connected from the default bond.
Answer: A,B,E
Explanation:
These are the three steps that the administrator must take to increase throughput to the host. According to the network diagram, the host has two 10Gb interfaces and two 1Gb interfaces in the default bond, but only one of the 10Gb interfaces is connected to a switch. The other 10Gb interface is disconnected and has a red "X" on it. The two 1Gb interfaces are also disconnected and have dotted lines. This means that the host is using only one 10Gb interface for all its network traffic, which limits its maximum bandwidth to 10 Gbps.
To increase the throughput, the administrator should connect both 10Gb interfaces to the physical switch, preferably to different switches for redundancy and high availability. This will allow the host to use both 10Gb interfaces for network traffic, which can increase its maximum bandwidth to 20 Gbps. However, this also requires changing the bond mode from active-backup to balance-slb or balance-tcp, which are load balancing modes that distribute network traffic across multiple interfaces based on source MAC address or TCP session1. The default bond mode of active-backup only uses one interface at a time and switches to another interface only when the active one fails2.
Finally, the administrator should remove any 1Gb interfaces still connected from the default bond, as they are not needed and may cause performance issues or conflicts with the load balancing modes. The 1Gb interfaces can be used for other purposes, such as management or backup networks, by creating separate bonds or bridges for them3. Alternatively, they can be left disconnected if they are not required.
NEW QUESTION # 68
Which command should an administrator run from the CLI to view the uplink state of all AHV nodes in the cluster?

NEW QUESTION # 71
An administrator has an AHV cluster that is comprised of 4 nodes with the following configuration in each node:
CPU:2 each 2.4GHz, 12 core
Memory: 256GB
Disk: 6 each 1.92 SSD
A VM with 16 vCPUs and 96GB of RAM is being created on the cluster.
How should the administrator configure the VM to assure optimal performance?
- A. With 2 vNUMA nodes
- B. With Flash Mode enabled
- C. With memory overcommit
- D. With an affinity policy
Answer: A
Explanation:
The best way to configure the VM for optimal performance is to set it up with 2 vNUMA nodes. This will ensure that the VM is configured to take advantage of the CPU and memory resources available in each node, and it will also ensure that all of the cores are utilized for the best performance. Additionally, the administrator should ensure that the VM has an affinity policy set up so that the vCPUs are evenly distributed across the four nodes. Finally, Flash Mode should be enabled in order to take advantage of the high-performance SSDs that are available in the cluster
NEW QUESTION # 72
Which capability refers to the storage of VM data on the node where the VM is running and ensure that the read I/O does not have to traverse the network?
- A. Data Locality
- B. Intelligent Locally
- C. Data Tiering
- D. Intelligent Tiering
Answer: A
Explanation:
Data locality is the capability of storing VM data on the node where the VM is running and ensuring that the read I/O does not have to traverse the network. Data locality is a unique feature of Nutanix that provides high performance and low latency for VMs by minimizing network traffic and crosstalk. Data locality works by writing one copy of the data local to the VM and the other copy (or copies) on other nodes. When a VM migrates to another node, Nutanix also moves its data to the new node and serves all I/O requests locally. Data locality also adapts to changing workloads and access patterns by dynamically moving data to where it is needed most1.
