A. This statement is incorrect because there is no static threshold set to trigger a critical alert at 6000 MB. The graph shows a peak that goes above 6000 MB, but the alert configuration below does not specify a static threshold at this value.

B. This is the correct statement. The configuration under "Behavioral Anomaly" is set to alert every time there is an anomaly, with a critical level alert set to trigger when the I/O working set size is between 0 MB and 4000 MB. The graph illustrates that the anomalies (highlighted in pink) occur when the working set size exceeds the normal range (blue band). Therefore, any anomaly detected above 4000 MB would trigger a critical alert.

C. This statement is incorrect because there is no indication that a warning alert is configured to trigger after 3 anomalies. The exhibit does not show any configuration that specifies an alert based on the number of anomalies.

D. This statement is incorrect as there's no indication that a warning alert will be triggered based on the I/O working set size exceeding the blue band. The alert settings are configured to ignore anomalies below 4000 MB and to trigger a critical alert for anomalies above this threshold.

The settings displayed in the exhibit are typically part of Nutanix's Prism infrastructure management platform, which can set various thresholds for performance metrics and trigger alerts based on those thresholds. The behavior is defined in the Prism documentation where the alert configuration is outlined.

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.

When a VM is connected to a Nutanix managed network, the IP address is assigned when the VM is powered on. A Nutanix managed network is a network that is created and managed by Prism Central using IP address management (IPAM). IPAM allows Prism Central to automatically assign IP addresses to VMs from a pool of available addresses in a subnet. IPAM also tracks the IP address usage and availability across clusters and networks4.

When a VM is connected to a Nutanix managed network, the administrator can choose one of the following assignment types for the IP address:

• Assign Static IP: This option allows the administrator to manually specify a static IP address for the VM from the subnet range. The IP address will not change unless the administrator changes it.
• Assign with DHCP: This option allows Prism Central to dynamically assign an IP address for the VM from the subnet range using DHCP. The IP address may change depending on the DHCP lease time and availability.
• No Private IP: This option allows the administrator to skip assigning an IP address for the VM. This option is useful for scenarios where the administrator wants to use an external IPAM solution or assign an IP address later5.

Regardless of the assignment type, the IP address is assigned when the VM is powered on. This is because Prism Central needs to communicate with the hypervisor (AHV or ESXi) to configure the virtual NIC (vNIC) of the VM with the IP address information. This communication can only happen when the VM is in a powered on state6.

A constrained VM is one that does not have enough resources for the demand and can lead to performance bottlenecks. A VM is considered constrained when it exhibits one or more of the following baseline values, based on the past 21 days: CPU usage > 90% (moderate), 95% (severe) CPU ready time > 5%, 10% Memory usage > 90%, 95% Memory swap rate > 0 Kbps1. To provide adequate host resources, resize (increase) the constrained VMs1.
