74. Frage
Which Nutanix license tier includes the ability to enable microsegmentation using Flow Network Security?
Antwort: B
Begründung:
Flow Network Security microsegmentation is included with the NCI Ultimate feature set. Microsegmentation applies policy-based controls between protected workloads, allowing administrators to restrict east-west traffic according to categories, application tiers and defined security requirements. Because this is an infrastructure networking and security capability, its core entitlement is associated with Nutanix Cloud Infrastructure rather than Nutanix Cloud Manager.
The official Nutanix software-options matrix distinguishes between inclusion and add-on availability. NCI Ultimate includes microsegmentation. NCI Pro can support the capability when the applicable Security add- on is purchased, but the base NCI Pro tier alone does not include that entitlement. NCI Starter does not provide the required microsegmentation entitlement. NCM Ultimate includes advanced cloud-management, governance and security-compliance functions, but it does not replace the NCI entitlement needed to enforce Flow Network Security policies on protected workloads.
Therefore, among the listed standalone tiers, NCI Ultimate is the tier that includes the ability directly. This distinction is important in exam questions: a feature being available as an add-on to a tier is not equivalent to being included in the base tier.

What is the role of Nutanix Insights?
Antwort: A
Begründung:
Nutanix Insights is a predictive health and support-automation service that analyzes diagnostic telemetry received from registered Nutanix environments. Its primary function is to identify infrastructure-health gaps, detect known risks, recommend corrective actions, and streamline the support process before an issue becomes operationally disruptive. Nutanix states that system-level diagnostic telemetry is analyzed to produce actionable infrastructure insights. Insights can also automate support-case creation, log collection, and the assignment of appropriate support resources.
Option A therefore describes the service accurately. Real-time CPU and memory monitoring in option B is primarily performed through Prism performance dashboards, VM metrics, and analysis charts. Workload migration between environments is associated with technologies such as Nutanix Move and Nutanix Cloud Clusters rather than Insights. Initial node imaging and cluster creation in option D are Foundation functions.
Insights normally works with Nutanix Pulse, which supplies the required diagnostic information. This makes Insights a proactive support capability, not merely another local monitoring dashboard.

76. Frage
Which protocols does the Network Visualizer leverage to discover and display network connections and statistics?
Antwort: B
Begründung:
Nutanix Network Visualizer uses Link Layer Discovery Protocol or Cisco Discovery Protocol to determine the relationship between an AHV host interface and the corresponding first-hop physical-switch port. It can then use configured SNMP access to retrieve additional switch, port and operational statistics. The combined protocol set in option C therefore enables both topology discovery and the display of useful physical-network information.
LLDP is vendor-neutral, while CDP is primarily associated with Cisco networking equipment. Either protocol can advertise the local port identity needed to construct the topology mapping. SNMP supplements that discovery by providing management-plane information obtained from supported switches. Nutanix documentation notes that when LLDP or CDP information is unavailable, SNMP data may be used to assist mapping, although complete and accurate visualization depends on supported devices and appropriate configuration.
BGP and OSPF exchange routing information; they are not the protocol set used by Network Visualizer for host-to-switch discovery. DHCP and PXE provide address allocation and network boot services. STP prevents Layer 2 loops, while VTP distributes VLAN information in certain Cisco environments.

77. Frage
An administrator needs to increase the available storage of an existing AHV virtual machine by adding a new vDisk.
Which method is supported to perform this task?
Antwort: C
Begründung:
An administrator can add storage directly to an existing AHV VM by editing its configuration and selecting Add New Disk. In the disk configuration, the administrator specifies the device type, disk size, storage container, and supported controller or bus settings. The new vDisk is then attached to the VM and presented to the guest operating system, where it can be initialized, partitioned, and formatted.
Creating another VM is unnecessary because AHV supports modifying the virtual hardware of an existing VM. Increasing a host's local disk does not directly create guest storage; physical disks contribute capacity to the Nutanix distributed storage fabric rather than being individually assigned to a VM. Similarly, changing the size of a storage pool is an infrastructure-capacity operation and does not attach a new virtual disk to the selected workload.
A storage container holds the vDisk and provides access to the cluster's distributed storage resources.
Selecting the appropriate container during disk creation is therefore part of the supported workflow.

78. Frage
An administrator needs to configure cluster fault tolerance of 1N & 1D.
How many nodes must the cluster have for this task?
Antwort: D
Begründung:
The 1N & 1D cluster fault-tolerance level is supported on a three-node cluster. It is designed to maintain access to data when one complete node and one additional disk fail concurrently, provided that the failures and remaining resources satisfy the documented resiliency conditions. To achieve this protection level, the platform configures replication factor 3 for the relevant data and maintains three metadata copies.
This configuration is distinct from standard 1N/1D fault tolerance, which protects against either one node failure or one disk failure and normally uses data replication factor 2. The ampersand in 1N & 1D is technically significant because it indicates simultaneous node-and-disk protection.
A two-node cluster uses a separate witness-based architecture and cannot provide this three-node 1N & 1D configuration. Nutanix documentation identifies three as both the required and supported node count for this specific fault-tolerance mode. Larger conventional clusters use their applicable fault-tolerance configurations rather than treating 1N & 1D as an arbitrary scalable setting.
Administrators must also verify that the cluster has sufficient resilient capacity before enabling the higher protection level. References: Prism 7.5 - One Node and One Disk Cluster Fault Tolerance and Cluster Fault Tolerance .
