NEW QUESTION # 36
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. The VM OS hung during migration.
- C. NO AHV hosts were able to be scheduled.
- D. The VM was on the same host as the acropolis leader.
Answer: A
NEW QUESTION # 37
A recently configured cluster is leveraging NearSync with a recovery schedule of 15 minutes. It is noticed that the cluster is consistently transitioning in an Out of NearSyne.
What action should be taken to potentially address this issue?
- A. Increase network bandwidth
- B. Add a vCPUs to the user VMs.
- C. Change the NearSync schedule to 30 minutes.
- D. Configure a secondary schedule in the same Protection Domain.
Answer: A
Explanation:
One of the possible reasons for a cluster to transition out of NearSync is insufficient network bandwidth between the source and target clusters. NearSync requires a minimum network bandwidth of 10 Mbps per VM for replication3. If the network bandwidth is lower than the required amount, the replication of recovery points may take longer than the configured RPO, resulting in an Out of NearSync condition. To address this issue, you can increase the network bandwidth between the clusters or reduce the number of VMs protected by NearSync4.

NEW QUESTION # 39
An administrator has a Custom backup application that requires a 2TB disk and runs m Windows. Throughput is considerably lower than expected.
The application was installed on a VM with the following configuration:
* FOU vCPUs with one core/vCPU
* 4GB of Memory
* One 50GB vDisk for the Windows installation
* One 2TB vDisk for the application
What is the recommended configuration change to improve throughput?
- A. Increase the number of cores per vCPU
- B. Increase the vCPUs assigned to the VM
- C. Add 4GB of memory to the VM
- D. Span the 2TB disk across four vDisks
Answer: D
Explanation:
According to the web search results, one recommended configuration change to improve throughput for a custom backup application that requires a 2TB disk and runs on Windows is to span the 2TB disk across four vDisks. Spanning is a technique that allows you to create a single logical disk from multiple physical disks. Spanning can improve throughput by distributing I/O requests across multiple disks and reducing contention5. To span a disk across four vDisks, the administrator should create four vDisks of equal size (500 GB each) and attach them to the VM. Then, in Windows Disk Management, create a spanned volume from the four vDisks and format it as NTFS6.

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 a vDisks stored in a RF1 Datastore
- B. LinuxVM1 uses e vDisks stored in a RF3 Datastore
- C. LinuxVM1 uses a virtual GPU.
- D. LinuxVM1 uses a Volume Group
Answer: A
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 # 44
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. VLANS12 is a reserved VLAN ID, and not usable for guest VMs.
- B. The administrator did not create the VLAN on all hosts
- C. There is a firewall rule blockingVLAN512 traffic.
- D. The VLAN was not created on the upstream switches.
Answer: D
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 # 45
Refer to Exhibit:
An administrator is trying to create a custom alert policy for all VMs.
Why is the Alert warning if field greyed cut?
- A. The Behavioral Anomaly threshold is set.
- B. The Auto resolve alerts option is checked.
- C. The Enable Policy option checked.
- D. The Alert critical if threshold is set.
Answer: A
Explanation:
when you create a custom alert policy, you can choose between two types of thresholds: Static Threshold and Behavioral Anomaly. Static Threshold allows you to set a fixed value for the metric that triggers the alert.
Behavioral Anomaly allows you to use machine learning to detect abnormal behavior based on historical data.
If you select Behavioral Anomaly as the threshold type, you cannot set a warning level for the alert. You can only set a critical level that indicates how much deviation from normal behavior is considered an anomaly3.
Therefore, the Alert warning if field is greyed out when you select Behavioral Anomaly.
NEW QUESTION # 46
Where should an administrator unregister Prism Element from Prism Central?
- A. From a Host SSH session
- B. From the Prism Element web console
- C. From the Prism Central web console
- D. From a CVM SSH session
Answer: A
Explanation:
This is because there is no GUI method to unregister a cluster from Prism Central, so the process requires SSH access to the PC VM as well as to a CVM of the cluster2. The unregistration process involves getting the UUID of the cluster from the CVM and then using that to trigger de-registration from PC command line2. The unregistration process also involves cleaning up any associated metadata and configuration on both PC and PE2. Therefore, the administrator needs to use a Host SSH session to perform this task.

NEW QUESTION # 49
Which scenario would benefit most from Erasure Coding being enabled on a container?
- A. Long term storage of data which is written once and read infrequently
- B. VDI use cases where a single VM is cloned 100's of times
- C. High performance database where all is relatively hot.
- D. WEB and API Servers
Answer: A
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 # 50
An administrator is preparing to deploy a new application on an AHV cluster, Security requirements dictate that all virtual servers supporting this application must be prevented from communicating with unauthorized hosts.
Which option would achieve this goal?
- A. Create a new solation Environment policy apply it to the new servers and all authorized hosts.
- B. Create new' subnet and assign to an existing VPC assign the IP prefix and gateway for the subnet, deploy servers with vNlC5 in the new subnet.
- C. Create a new VLAN, create a subnet on the cluster with the VLAN tag, deploy servers with vNlCs in the new subnet.
- D. Create a new Application Security Policy restricting communication to the authorized hosts and apply it to the servers in enforce mode.
Answer: D
Explanation:
An Application Security Policy is a security feature in Nutanix AHV that can be used to restrict network communication between virtual servers based on a variety of criteria, such as IP address, port, and protocol.
By creating a policy that restricts communication to authorized hosts and applying it to the servers in enforce mode, the administrator can prevent unauthorized communication between virtual servers.

NEW QUESTION # 51
Which two methods are available when migrating a VM from a legacy 3-tier solution using VMware ESXi to AHV? (Choose two.)
- A. Use Cross-Hypervisor DR.
- B. Import the .vmdk into the Image Service.
- C. Deploy the Move appliance.
- D. Use shared nothing live migration.
Answer: B,C
Explanation:
Deploy the Move appliance and Import the .vmdk into the Image Service. These are two methods that can be used to migrate a VM from VMware ESXi to AHV2. The Move appliance is a tool that automates the migration process by converting the VM disks and configuration to AHV format and transferring them to the Nutanix cluster3. The Image Service is a feature that allows users to upload and manage disk images that can be used to create or clone VMs on AHV4. By importing the .vmdk file of the VMware VM into the Image Service, users can create a new AHV VM from that image.
