24. Frage
An administrator needs to configure cluster fault tolerance of 1N & 1D.
How many nodes must the cluster have for this task?
Antwort: C
Begründung:
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 .
25. Frage
When creating a new VLAN, what should be specified as the VLAN ID if a network interface uses the Native VLAN?
Antwort: C
Begründung:
In Nutanix AHV network configuration, VLAN ID 0 represents the native or untagged VLAN. Therefore, when a VM network interface must communicate through the native VLAN on the connected physical-switch port, the administrator specifies VLAN ID 0 while creating the VLAN-backed virtual network.
The native VLAN carries Ethernet frames without a conventional 802.1Q VLAN tag across the applicable switch connection. Nutanix uses the value 0 as the administrative representation for this untagged behavior. It does not mean that an ordinary production VLAN numbered zero is being created on the physical switch. The physical switch port and AHV uplink configuration must still agree on which traffic is treated as native or untagged.
VLAN ID 1 is commonly a switch default but is not Nutanix's required value for designating native-VLAN behavior. VLAN 255 is an otherwise ordinary numerical VLAN identifier and has no special native-VLAN meaning. VLAN 4096 is outside the usable IEEE 802.1Q VLAN range; Nutanix accepts VLAN identifiers through 4094 for normal tagged VLAN configurations.

26. Frage
When managing licenses manually, what is the first step to start the licensing workflow?
Antwort: B
Begründung:
The manual licensing workflow begins by downloading a cluster summary file from the Licensing area in Prism Central Admin Center. The cluster summary file contains the deployment and consumption information that Nutanix License Manager requires to identify the relevant clusters and determine which entitlements can be allocated.
After downloading the cluster summary file, the administrator uploads it to Nutanix License Manager in the Support Portal, selects or allocates the appropriate licenses and generates a license summary file. That license summary file is subsequently downloaded from the portal and uploaded back into Prism Central. Therefore, the cluster summary file is the workflow's initial outbound file, while the license summary file is the resulting inbound file.
Option D reverses this sequence: Prism Central does not generate the license summary file at the start. Option A confuses the file type and management interface. Prism Element may appear in certain legacy-license procedures, but the question specifically addresses Prism Central Admin Center licensing. Contacting Support is not required for the standard manual workflow.

27. Frage
An administrator runs a cluster health check and notices that a specific plugin returns a WARN status.
How should the administrator interpret this status?
Antwort: D
Begründung:
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.

28. Frage
An administrator needs to increase the available storage of an existing AHV virtual machine by adding a new vDisk.
Which method is supported to perform this task?
Antwort: A
Begründung:
An administrator can add storage directly to an existing AHV VM by editing its configuration and selecting Add New Disk. In the disk configuration, the administrator specifies the device type, disk size, storage container, and supported controller or bus settings. The new vDisk is then attached to the VM and presented to the guest operating system, where it can be initialized, partitioned, and formatted.
Creating another VM is unnecessary because AHV supports modifying the virtual hardware of an existing VM. Increasing a host's local disk does not directly create guest storage; physical disks contribute capacity to the Nutanix distributed storage fabric rather than being individually assigned to a VM. Similarly, changing the size of a storage pool is an infrastructure-capacity operation and does not attach a new virtual disk to the selected workload.
A storage container holds the vDisk and provides access to the cluster's distributed storage resources.
Selecting the appropriate container during disk creation is therefore part of the supported workflow.
