質問 # 15
Which component is required to prevent split-brain scenarios on a two-node ROBO cluster?
正解：C
解説：
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.
質問 # 16
What is the default time that a Nutanix cluster will run an LCM auto inventory and auto update?
正解：C
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 # 17
An administrator runs a cluster health check and notices that a specific plugin returns a WARN status.
How should the administrator interpret this status?
正解：D
解説：
An NCC WARN status means the health-check plugin returned an unexpected value that requires administrator investigation. Nutanix states that a warning requires user intervention and should be resolved as soon as reasonably possible. A warning is significant, but it is distinct from an NCC failure indicating that the tested aspect is currently unhealthy.
The answer choices deliberately correspond to different NCC result classifications. Option A describes an execution error: the plugin did not run successfully and therefore cannot establish a valid PASS, INFO, WARN, or FAIL result. Option B describes a FAIL condition, where the tested cluster component or state is unhealthy and can require immediate corrective action. Option D describes INFO, in which the plugin returns an expected informational value that cannot be classified as a straightforward pass or failure.
Administrators should read the complete warning output because it normally identifies the affected check, entity, observed value, expected condition, and recommended remediation. The warning should then be correlated with Prism alerts, recent changes, and other NCC results. It must not be ignored merely because the cluster remains operational.

質問 # 18
Which Nutanix product provides unstructured file-storage services through SMB and NFS for home directories and user profiles on a Nutanix cluster?
正解：A
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 # 19
An administrator has identified and resolved a critical alert on the health dashboard.
What should the administrator do to confirm the alert/issue has been resolved?
正解：B
解説：
The administrator should rerun the relevant Nutanix Cluster Check after completing the corrective action.
NCC evaluates cluster configuration, services, hardware and operational conditions against Nutanix-defined health criteria. A new PASS or appropriate INFO result provides technical confirmation that the underlying condition no longer exists.
Refreshing the Prism Element dashboard only reloads the displayed information. It does not independently retest the component or service that generated the alert. Deleting an email notification has no effect on the alert or cluster state. Manually marking an alert as resolved changes its administrative status but does not prove that the underlying fault has been corrected. Doing so without validation could conceal an active problem.
If the rerun produces WARN, FAIL or ERR rather than PASS or INFO, the administrator must review the new output and continue remediation. For a narrowly scoped issue, the relevant NCC check can be selected; a broader health review may justify running the complete NCC suite.
