NEW QUESTION # 60
Which Nutanix storage feature reduces space usage by eliminating identical data blocks?
Answer: D
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 # 61
Refer to the exhibit.
The VM memory-usage graph shows a measured value of approximately 42.95%, with the utilization line remaining inside the blue baseline band.
What should be considered regarding memory usage?
Answer: B
Explanation:
The VM's memory-consumption line remains inside the blue baseline band, so its behavior falls within the learned baseline range. Prism Central uses historical observations and machine-learning analysis to establish the range of values normally expected for an entity and metric. The blue band represents that expected operating range; a value outside the band may be identified as anomalous, depending on duration and deviation.
The displayed value of approximately 42.95% is below 50%, which immediately invalidates option A. More importantly, memory-utilization percentage represents the portion of the VM's allocated memory currently being consumed. It does not mean the host can provide only that percentage of the requested memory, so option C incorrectly interprets utilization as a resource-allocation failure.
The graph also does not provide sufficient evidence to halve the VM's configured memory. Right-sizing requires longer-term utilization, swap activity, workload requirements, peak behavior, and operational policy-not a single observed percentage. Option D therefore recommends an unsupported configuration change.
The correct operational conclusion is limited and precise: the measured behavior is within the VM's learned normal range and is not shown as an anomaly.

NEW QUESTION # 62
Which Nutanix solution allows running NCI on AWS or Microsoft Azure bare-metal infrastructure?
Answer: B
Explanation:
Nutanix Cloud Clusters, commonly identified as NC2, deploys the core Nutanix Cloud Infrastructure software stack on bare-metal resources supplied by public-cloud providers. That stack includes AOS, AHV, and Prism, giving administrators a consistent infrastructure and operational model across on-premises Nutanix environments and supported public clouds. For the examination scope, AWS and Microsoft Azure are the relevant providers.
NC2 does not merely expose external storage to an existing cloud-native hypervisor. It establishes a Nutanix cluster on cloud bare-metal instances, allowing workloads to retain familiar Nutanix storage, virtualization, management, and resilience characteristics. This supports migration, disaster recovery, datacenter extension, and temporary capacity expansion without requiring applications to be substantially refactored.
Nutanix Flow supplies networking and security capabilities; it is not the platform that instantiates NCI clusters on public-cloud bare metal. AOS Storage is the distributed storage layer within the Nutanix platform, not the complete cloud deployment solution. "NCI with External Storage" describes neither the recognized product name nor the NC2 deployment architecture.
The operative phrases are "NCI," "AWS or Microsoft Azure," and "bare-metal infrastructure." Together, they identify NC2 unambiguously.

NEW QUESTION # 63
Which Nutanix solution provides microsegmentation and application-centric security policies for VMs?
Answer: A
Explanation:
Flow Network Security provides application-centric microsegmentation and distributed security-policy enforcement for Nutanix workloads. It uses categories and application context to define which workloads may communicate, rather than depending exclusively on static IP addresses or physical VLAN boundaries.
Policies can follow VMs as they move or scale within supported Nutanix environments.
Microsegmentation limits east-west communication between application components and reduces the potential lateral movement of malware or unauthorized users. Administrators can define policies for application tiers, environments, user groups and isolation requirements, then manage those policies centrally through Prism Central. Flow Network Security also provides traffic visualization and policy-monitoring capabilities before enforcement.
AHV supplies the virtualization and host-compute layer but is not, by itself, the security-policy product identified by the question. AOS provides distributed storage, resilience and data services. Nutanix Disaster Recovery manages workload protection, replication and recovery rather than distributed microsegmentation.

NEW QUESTION # 64
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.
