質問 # 62
An administrator is troubleshooting resource availability within the cluster. As part of the troubleshooting, the administrator wants to build a list of powered-off VMs on the Nutanix cluster.
In order for these VMs to be listed in the Prism Central VM Efficiency widget, how many days must the VMs be powered off to be considered a Dead VM?
正解：B
解説：
Prism Central classifies a virtual machine as a Dead VM after it has remained powered off for at least 30 days. The VM Efficiency capability uses this duration to distinguish temporarily stopped workloads from VMs that are sufficiently inactive to justify administrative review. Consequently, a VM powered off for only
5 or 15 days does not meet the classification threshold, while 45 days exceeds-but does not define-the required minimum.
A Dead VM is not automatically deleted. The classification is an efficiency finding intended to identify resources that may no longer be required. Even while powered off, the VM can continue consuming storage through its virtual disks, snapshots, recovery points, and associated configuration objects. Administrators should therefore validate application ownership, retention requirements, protection policies, and compliance obligations before deleting or archiving it.
The VM Efficiency widget is part of Prism's broader behavioral and capacity-optimization functionality.
Other inefficiency classifications can identify overprovisioned or constrained VMs by evaluating historical resource behavior. The 30-day rule is specifically associated with the powered-off Dead VM condition and should not be confused with utilization-based efficiency findings.
NHCF/NCA reference: Prism Central monitoring, VM efficiency, resource optimization, and behavioral analysis. Official reference: Behavioral Learning Tools and VM Efficiency , specifically the Dead VM classification.

What is the default time that a Nutanix cluster will run an LCM auto inventory and auto update?
正解：A
解説：
The default scheduled time for LCM automatic inventory and automatic update activity is 3:00 AM. This setting is used when Auto Inventory and Auto Update are enabled for a connected site. Administrators can modify the schedule when 3:00 AM does not align with the organization's operational or maintenance requirements.
Automatic inventory refreshes LCM's knowledge of installed software and firmware components and retrieves current update metadata from the configured Nutanix source. Nutanix also specifies that if an inventory operation has already completed within the preceding 12 hours, LCM can skip the scheduled auto- inventory because its component information remains sufficiently current. Automatic update in this setting applies to the supported automatically managed component-particularly Nutanix Cluster Check-rather than authorizing every available AOS, AHV, or firmware upgrade without administrator review.
The other answer choices do not represent the documented default. However, administrators should treat 3:00 AM as a configurable platform default rather than an assumed maintenance window. They must verify the configured schedule, time context, Internet connectivity, and update policy for the specific environment.

質問 # 64
An administrator needs to configure cluster fault tolerance of 1N & 1D.
How many nodes must the cluster have for this task?
正解：C
解説：
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 .
質問 # 65
Which Nutanix product provides unstructured file-storage services through SMB and NFS for home directories and user profiles on a Nutanix cluster?
正解：B
解説：
Nutanix Files is the scale-out file-storage service designed to provide SMB shares and NFS exports for unstructured data. Typical use cases include user home directories, roaming or virtual-desktop profiles, departmental shares, application logs, archives, and general enterprise file services. Files deploys File Server VMs that present the client-facing file protocols while using the Nutanix distributed storage layer underneath.
Nutanix Move is a workload-migration utility used to transfer VMs between supported source and target platforms; it does not provide file shares. Nutanix Volumes supplies block-storage services, commonly exposed through iSCSI, for applications that require block devices rather than SMB or NFS file systems.
Nutanix Objects provides S3-compatible object storage and is intended for applications using object APIs rather than conventional file protocols.
The presence of SMB, NFS, home directories, and user profiles makes the use case specifically file-oriented.
Nutanix documentation identifies Files as a repository for unstructured data and lists home directories and user profiles among its standard workloads. Reference: Nutanix Files Storage Technical Note . NHCF alignment: differentiating Files, Volumes, Objects, and migration services by protocol and workload type.
質問 # 66
What is Multicloud Snapshot Technology (MST)?
正解：C
解説：
Multicloud Snapshot Technology is a Nutanix disaster-recovery and data-mobility capability that replicates VM and Volume Group snapshots directly to supported object storage. Supported targets can include Nutanix Objects and validated hyperscaler services such as Amazon S3 or Azure Blob Storage, depending on the deployed MST and platform versions.
Object storage supplies a durable and cost-effective repository without requiring a fully sized recovery cluster to remain continuously active. During recovery, the protected snapshots can be rehydrated or restored to a Nutanix Cloud Platform environment. MST integrates with Prism Central protection policies and recovery plans, providing a consistent operational workflow across on-premises, edge and public-cloud deployments.
MST is not limited to bare-metal servers, native-cloud VMs or one fixed NC2-to-on-premises direction. Its defining characteristic is the use of supported object storage as the snapshot-protection target and its ability to support recovery wherever the compatible Nutanix Cloud Platform is available. Option C therefore provides the broad and technically correct definition.
