NEW QUESTION # 15
Which protocols does the Network Visualizer leverage to discover and display network connections and statistics?
Answer: D
Explanation:
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.

NEW QUESTION # 16
Monitoring data shows stable CPU and memory usage, but a user VM remains slow.
Which area should be investigated next?
Answer: A
Explanation:
Once CPU consumption, CPU contention and memory utilization have been reviewed and found stable, storage latency becomes the next relevant performance domain. A VM can have adequate compute resources yet remain slow because guest read or write operations are waiting for the storage path. High latency may arise from workload contention, abnormal I/O patterns, a storage-controller issue, or an underlying infrastructure condition.
Prism exposes VM and infrastructure metrics including IOPS, bandwidth, read latency, write latency and total I/O latency. The administrator should correlate the VM's latency with its IOPS and throughput, then compare those values with storage-container, host and cluster-level metrics over the same interval. This determines whether the delay is isolated to the VM or reflects a broader storage condition.
License expiration may affect access to licensed features, but it is not the primary diagnostic explanation for an actively running VM's I/O responsiveness. RBAC controls administrative permissions rather than guest workload performance. Container sizing is not a standard immediate troubleshooting metric; the measurable symptom to examine first is latency.

NEW QUESTION # 17
Which component is required to prevent split-brain scenarios on a two-node ROBO cluster?
Answer: A
Explanation:
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.
NEW QUESTION # 18
Where should a support ticket be opened with Nutanix?
Answer: C
Explanation:
A Nutanix support ticket should be opened from the case-management area of the Nutanix Smart Support or Support Portal by navigating to Cases and selecting the option to create or open a case. This location provides access to existing cases, entitlement and asset information, severity selection, problem descriptions, and diagnostic uploads.
The Account area is used for account-related administration and is not the normal navigation path for submitting a technical case. Prism Element also does not provide a User-menu path named Create Case, eliminating option A.
Current Prism Central releases can expose support-case functionality, but the documented navigation is through the Help icon and Create Support Case-not through the User menu stated in option C. Therefore, option C is incorrect as written even though Prism Central may integrate with Nutanix Support.
When creating the case, the administrator should provide the affected cluster or asset, AOS and hypervisor versions, severity, business impact, recent changes, timestamps, and relevant logs. Accurate case classification and diagnostic information reduce investigation time.

NEW QUESTION # 19
A virtual machine needs to be placed on a different storage location within the cluster.
Which task should be performed?
Answer: D
Explanation:
Moving a VM's existing storage to a different storage container requires a vDisk placement change, implemented through live vDisk migration across storage containers. Nutanix supports migrating the attached vDisks of a running VM to a target container without deleting or shutting down the VM, subject to the documented requirements and limitations. The administrator can move an individual vDisk or all supported vDisks belonging to the VM.
A category assigns metadata used for organization, governance, automation, and policy association; it does not directly relocate existing disk data. Image placement policies determine which clusters receive images from the image service, not where an existing VM's attached vDisks are stored. A storage policy controls storage characteristics such as QoS or other supported data-service properties. It is not the general storage- container migration task.
The keyed answer D is particularly problematic because Nutanix documents that a vDisk cannot be migrated to another container while a storage policy is configured for the associated VM. Applying such a policy can therefore prevent the requested migration rather than accomplish it. References: Migrating a vDisk to Another Container and Storage Policy Management . NHCF alignment: storage operations and vDisk management.
