NEW QUESTION # 12
Which component is required to prevent split-brain scenarios on a two-node ROBO cluster?
Answer: B
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 # 13
When migrating ESXi VMs to an AHV-based cluster using Nutanix Move, what should be in place to ensure a successful migration?
Answer: A
Explanation:
Nutanix Move requires VMware Tools to be installed and current on guest VMs for supported ESXi-to-AHV migration workflows. VMware Tools provides guest-level information and operations needed during migration preparation and cutover. Its services support tasks such as obtaining guest details, coordinating shutdown or restart actions, and completing supported guest-side preparation.
Placing ESXi hosts in maintenance mode would normally evacuate or stop workloads and is not a standard migration prerequisite. Move is designed to migrate selected running workloads while the source infrastructure remains operational until cutover. Option C is incorrect because official Move requirements specify virtual hardware version 7 or later for the relevant support condition, not version 9 or later. Option D is also too restrictive: supported Move releases accommodate documented ESXi versions beyond only the 7.x family, subject to the current compatibility matrix.
Administrators must also verify network reachability, credentials, guest-operating-system support, source and target compatibility, and adequate target resources. However, among the choices, the explicit guest requirement is current VMware Tools. Reference: Nutanix Move 6.2 - Requirements . NHCF alignment:

NEW QUESTION # 14
Which Nutanix storage feature reduces space usage by eliminating identical data blocks?
Answer: A
Explanation:
Deduplication reduces storage consumption by identifying duplicate data blocks and consolidating them so that redundant physical copies do not need to be retained. AOS uses fingerprints to recognize eligible duplicate blocks. Capacity deduplication applies this process to persistent data within a storage container, reducing the physical space consumed by workloads containing substantial repeated content.
Compression is different: it encodes a data block into a smaller representation but does not eliminate identical blocks by replacing them with a shared instance. Erasure Coding reduces the storage overhead associated with maintaining replicated cold data by substituting parity information for certain redundant copies. It is a resilience and capacity-efficiency mechanism, not duplicate-block elimination. Capacity Tiering concerns placement across storage tiers and does not consolidate identical content.
Deduplication should be enabled selectively because fingerprint generation and metadata processing introduce overhead. It is most beneficial for workloads with significant duplicate data, such as appropriate persistent- desktop or full-clone environments. Workloads already using space-efficient Nutanix clones may receive limited additional benefit.
The defining phrase in the question is "eliminating identical data blocks," which is the standard function of deduplication.

NEW QUESTION # 15
Which Nutanix product provides capabilities for advanced insights and automation for troubleshooting applications?
Answer: A
Explanation:
NCM Intelligent Operations provides centralized monitoring, advanced operational analytics, capacity planning, anomaly detection, resource optimization, reporting, and automation. It evaluates infrastructure and workload behavior across managed environments and helps administrators correlate performance conditions with affected applications and resources. Its automation capabilities can initiate predefined actions or playbooks when specified events, alerts, or operational conditions occur.
Nutanix Cloud Infrastructure supplies the core compute, storage, virtualization, networking, resilience, and management foundation. Although it exposes operational metrics through Prism, it is not the dedicated advanced analytics and automation product described in the question. Nutanix Enterprise AI is used to deploy, manage, monitor, and test large language models and inference endpoints. Nutanix Cloud Clusters extends Nutanix infrastructure into supported public-cloud environments but does not itself provide the specialized operational-intelligence feature set.
Intelligent Operations is specifically positioned as an end-to-end operations, monitoring, optimization, and planning solution. It can identify anomalous behavior, inefficient VMs, resource constraints, and capacity risks while reducing manual troubleshooting through automated workflows.

NEW QUESTION # 16
Which number of node(s) can be placed into maintenance mode at the same time in a cluster?
Answer: D
Explanation:
Nutanix permits only one node per cluster to be placed in maintenance mode at a time. This restriction protects cluster availability and ensures that sufficient compute, storage and metadata services remain operational while maintenance is performed. Before entering maintenance mode, Prism verifies whether the cluster has adequate resiliency and whether the workloads hosted by the node can be evacuated or otherwise handled safely.
For AHV, the maintenance workflow migrates eligible user VMs to other available hosts. The Controller VM on the affected node is then placed into an appropriate maintenance state so that storage services can continue through the remaining CVMs. Attempting to maintain multiple nodes simultaneously could exceed the cluster' s fault-tolerance capability, particularly if another unplanned node or disk failure occurs during the procedure.
The limitation is cluster-wide, not one node per hardware block. The absence of powered-on VMs also does not authorize every node to enter maintenance mode because AOS storage and cluster-control services still depend on quorum and service availability.
