Nutanix leverages a method for determining the bands called ‘Generalized Extreme Studentized Deviate Test’. A simple way to think about this is similar to a confidence interval where the values are between the lower and upper limits established by the algorithm.

Another web source3 shows an example of how anomaly detection works in Nutanix Prism Central. In the video, you can see that when the observed value of a metric deviates significantly from the predicted value based on historical data, an anomaly event is triggered and displayed on a chart.

Therefore, by comparing the observed values with the predicted values based on historical data, Nutanix anomaly detection can identify abnormal behavior and alert you accordingly.

According to section 5 of the exam blueprint guide1, one of the topics covered is live migration. Live migration is the process of moving a running VM from one host to another without any downtime or interruption of service. To perform live migration, there are some prerequisites that must be met, such as:

All AHV hosts have IP addresses in the same subnet

All VMs are configured for the same VLAN

The source and destination hosts have enough resources to accommodate the VM

The VM does not have any PCI devices attached

According to the Nutanix Files Guide, Nutanix Files instances are composed of a set of VMs (called FSVMs). Files requires at least three FSVMs running on three nodes to satisfy a quorum for high availability. By default, Files deploys three FSVMs when you create a file server instance.

Administrators can use Acropolis with IPAM to deliver a complete virtualization deployment, including network management, from the unified Prism interface. This capability radically simplifies the traditionally complex network management associated with provisioning VMs and assigning network addresses. To avoid address overlap, be sure to work with your network team to reserve a range of addresses for VMs before enabling the IPAM feature.

The Acropolis master assigns an IP address from the address pool when creating a managed VM NIC; the address releases back to the pool when the VM NIC or VM is deleted.

According to the web search results, Prism Central is a multi-cluster manager that provides a single, centralized management interface for Nutanix environments12. One of the features of Prism Central is multi-cluster Single Sign On (SSO), which allows users to log in once and access multiple clusters without re-entering credentials3.

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.
