39. Frage
When creating a new VLAN, what should be specified as the VLAN ID if a network interface uses the Native VLAN?
Antwort: D
Begründung:
In Nutanix AHV network configuration, VLAN ID 0 represents the native or untagged VLAN. Therefore, when a VM network interface must communicate through the native VLAN on the connected physical-switch port, the administrator specifies VLAN ID 0 while creating the VLAN-backed virtual network.
The native VLAN carries Ethernet frames without a conventional 802.1Q VLAN tag across the applicable switch connection. Nutanix uses the value 0 as the administrative representation for this untagged behavior. It does not mean that an ordinary production VLAN numbered zero is being created on the physical switch. The physical switch port and AHV uplink configuration must still agree on which traffic is treated as native or untagged.
VLAN ID 1 is commonly a switch default but is not Nutanix's required value for designating native-VLAN behavior. VLAN 255 is an otherwise ordinary numerical VLAN identifier and has no special native-VLAN meaning. VLAN 4096 is outside the usable IEEE 802.1Q VLAN range; Nutanix accepts VLAN identifiers through 4094 for normal tagged VLAN configurations.

40. Frage
An administrator is working with Nutanix Support and has been asked to submit the NCC logs for further review.
How should the administrator gather the logs for the support case?
Antwort: A
Begründung:
The supported Prism Element workflow for gathering diagnostic data is the Collect Logs feature. From the Health dashboard, the administrator opens the Actions menu, selects Collect Logs, identifies the relevant nodes and components, specifies the required time range or collection parameters, and starts the log-collection task. The resulting archive can then be associated with or uploaded for the Nutanix Support case.
Pulse is a proactive support and telemetry capability that periodically provides diagnostic system information to Nutanix. It does not automatically transmit every detailed NCC or component log required for a specific investigation. Nutanix documentation notes that when Pulse data is insufficient for diagnosis, Support may request a separate diagnostic log collection.
"Export Logs" and "Download Logs in Prism Central" are not the documented names of the NCC collection workflow described in the question. The explicit Health dashboard operation is Collect Logs. This process also allows the administrator to control which nodes and components are included, preventing irrelevant data from unnecessarily enlarging the support bundle.

41. Frage
Which minimum licensing option includes Container Storage Interface, Load Balancing, and Role-Based Access Control?
Antwort: C
Begründung:
NCI Pro is the minimum listed licensing option that includes the specified capabilities. Official Nutanix licensing documentation states that NKP Starter is included with NCI Pro and NCI Ultimate. NKP Starter provides the Nutanix CSI driver for persistent storage, role-based access control with single sign-on, and load- balancing and ingress services.
NKP Pro also contains these functions because it includes everything in Starter. However, it adds production- oriented services such as an observability stack, backup and restore, service mesh, serverless functions, broader deployment options, and additional platform capabilities. It is therefore not the minimum option among the answers.
NCI Ultimate includes the same NKP Starter entitlement but is a higher NCI tier than NCI Pro. NKP Ultimate is the highest NKP tier and adds fleet management, multitenancy, centralized observability, GitOps, cost management, application-catalog functions, and support for managing broader hybrid multicloud Kubernetes environments.
The decisive requirement is not simply which license contains the features; it is which listed option provides them at the lowest applicable tier. Since NCI Pro includes NKP Starter and Starter supplies CSI, load balancing, and RBAC, option C is technically correct.

42. Frage
Which technology helps maintain operational resilience related to hardware?
Antwort: A
Begründung:
Cluster Fault Tolerance directly defines how many simultaneous disk or node failures a Nutanix cluster can withstand within its configured failure domain while maintaining data availability. It is therefore the technology most directly associated with resilience against physical hardware failures.
For example, 1N/1D fault tolerance allows the cluster to tolerate the failure of one node or one disk, subject to the required node count, replication factor, available capacity, and current data-resiliency state. Higher fault- tolerance configurations can withstand additional simultaneous failures but require more nodes, failure domains, data copies, and usable-capacity overhead.
Acropolis Dynamic Scheduler addresses VM placement and resource contention. It can move workloads to improve balance, but it does not establish the number of hardware failures the storage layer can tolerate.
Capacity reservations can preserve resources for workload restart or data rebuilding, but they support rather than define the cluster's fault-tolerance level. High Availability restarts or protects VMs following host failures; it is related to workload availability but is not the specific measure of storage resilience across disks, nodes, blocks, or racks.
The decisive wording is "resilience related to hardware," which maps directly to Cluster Fault Tolerance.

43. Frage
Which component is required to prevent split-brain scenarios on a two-node ROBO cluster?
Antwort: D
Begründung:
A two-node cluster lacks the natural majority available in a conventional cluster containing three or more voting members. If communication between its two nodes is interrupted, each node could otherwise interpret the other node as failed and attempt to continue independently. That condition creates a split-brain risk because both sides could consider themselves authoritative.
The external Witness VM supplies the independent arbitration required for the two-node configuration. It is deployed in a separate failure domain and maintains communication with the cluster. During a node or communication failure, witness participation allows the cluster to distinguish the surviving authoritative side and avoid both nodes independently continuing cluster operations. Separating the witness from the two data- bearing nodes is critical because placing all voting components in the same failure domain would undermine the tie-breaking design.
Prism Element is the local cluster-management interface, while Prism Central provides centralized management across clusters. Neither substitutes for an independent quorum witness. Foundation Central supports centralized discovery and deployment activities and does not arbitrate two-node cluster ownership.
Nutanix documentation identifies the external Witness VM as part of the supported two-node ROBO configuration. References: Prism 7.5 - Two-Node Clusters and Witness for Two-Node Clusters . NHCF alignment: valid cluster configurations, availability, and failure handling.
