A Nutanix cluster is equipped with four nodes. Four VMs on this cluster have been configured with a VM-VM anti-affinity policy and are each being hosted by a different node.
What occurs to the cluster and these VMs during an AHV upgrade?
A. One node hosts two VMs while the node being upgraded is in maintenance mode.
B. One VM out of the four powers down when the node hosting it reboots.
C. The AHV pre-upgrade checks fail until the administrator disables the anti-affinity policy.
D. The AHV pre-upgrade checks fail until the four VMs are powered off.
Explanation: One node hosts two VMs while the node being upgraded is in maintenance mode. This is because Nutanix supports a feature called Rolling Upgrade that allows upgrading AHV on a cluster without any downtime or impact to the VMs. The Rolling Upgrade feature performs the upgrade one node at a time, by putting the node in maintenance mode, evacuating the VMs to other nodes, upgrading AHV, and then bringing the node back online. The VM-VM anti-affinity policy ensures that the four VMs are not placed on the same node during the evacuation process, so one node will host two VMs temporarily while the other node is being upgraded.
An administrator needs to bring down a host in a Nutanix Cluster for maintenance reasons. The administrator puts the host in maintenance mode.
What should the administrator do to perform an orderly shutdown of the CVM?
A. Execute the cvm_shutdown -P new command from the CVM.
B. Enter Fever off Server - immediate from the IPMI console.
C. Enter Fewer off Server-orderly Shutdown from the IPMI console.
D. Execute the cvm_shutdown -P now command from the host.
Explanation: According to the How to use the cvm_shutdown script web search result3, the cvm_shutdown script signals HA when shutting down the CVM (Controller VM) to forward the storage traffic to another healthy CVM. Instead of using sudo shutdown or sudo reboot commands, this script should be used to minimize I/O hits in user VMs running on the present hypervisor host. The cvm_shutdown -P now command will initiate the shutdown process on the CVM immediately. Therefore, if the administrator needs to perform an orderly shutdown of the CVM, they should execute this command from the CVM.
A guest VM should be able to tolerate simultaneous failure of two nodes or drives.
What are the minimum requirements for the Nutanix cluster?
A. 3 nodes with cluster RF 3 and container RF 3
B. 3 nodes with cluster RF 3 and container RF 2
C. 5 nodes with cluster RF 2 and container RF 3
D. 5 nodes with cluster RF 3 and container RF 3
Where are Leap Availability Zones configured?
A. Cloud Connect
B. Controller VM
C. Prism Element
D. Prism Central
Explanation:
Terminology
Availability Zone – it is represented by all resources (Nutanix Clusters) connected to Prism Central or Xi Leap Availability zone. Depends on the architecture, Availability zone can represent geographic territory, datacenter or server room in the datacenter. Protection policies – in protection policies you set up (RPO, Retention), rules to auto-apply policies to virtual machines.
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. 2000
B. 2074
C. 8080
D. 9943
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.
