質問 # 80
A virtual appliance provides network services required by other VMs on the same host. The VM should start before other VMs, shut down after other VMs, and remain associated with the same host during maintenance operations.
Which VM configuration best matches this requirement?
正解：B
解説：
The virtual appliance should be configured as an agent VM. AHV agent VMs are intended for infrastructure or service appliances that provide host-local functionality required by ordinary guest VMs. The agent designation gives the VM specialized power-order and placement behavior: it is powered on before normal VMs, powered off after normal VMs, and is not live-migrated to another host while running.
If the host experiences an HA event or enters maintenance mode, the agent VM is powered off rather than migrated. After the host returns to normal operation, the agent VM is powered on again on that same host.
This preserves the intended host-local association of services such as network, security, monitoring, or storage appliances.
VM-Host affinity alone expresses a placement preference or requirement but does not provide the complete agent-VM startup and shutdown ordering. Nutanix Guest Tools provides guest-management and snapshot capabilities, not host-local service-appliance semantics. Disconnecting the vNIC would prevent the appliance from delivering the stated network services.
All three requirements-startup priority, delayed shutdown, and host persistence-therefore identify the agent VM configuration.

Which Nutanix license tier includes the ability to enable microsegmentation using Flow Network Security?
正解：C
解説：
Flow Network Security microsegmentation is included with the NCI Ultimate feature set. Microsegmentation applies policy-based controls between protected workloads, allowing administrators to restrict east-west traffic according to categories, application tiers and defined security requirements. Because this is an infrastructure networking and security capability, its core entitlement is associated with Nutanix Cloud Infrastructure rather than Nutanix Cloud Manager.
The official Nutanix software-options matrix distinguishes between inclusion and add-on availability. NCI Ultimate includes microsegmentation. NCI Pro can support the capability when the applicable Security add- on is purchased, but the base NCI Pro tier alone does not include that entitlement. NCI Starter does not provide the required microsegmentation entitlement. NCM Ultimate includes advanced cloud-management, governance and security-compliance functions, but it does not replace the NCI entitlement needed to enforce Flow Network Security policies on protected workloads.
Therefore, among the listed standalone tiers, NCI Ultimate is the tier that includes the ability directly. This distinction is important in exam questions: a feature being available as an add-on to a tier is not equivalent to being included in the base tier.

質問 # 82
Which Nutanix support case priority level is used for a non-critical loss of use with medium to low impact?
正解：D
解説：
Nutanix classifies this condition as Priority 3, or P3. The official support definition describes P3 as a normal- priority case involving a minor inconvenience or an occasional, non-critical issue that requires resolution but has not materially reduced productivity. Its defining language includes: "A non-critical loss of use with medium to low impact." A short-term workaround is generally available.
P1 is reserved for emergency conditions in which production systems are unavailable or unusable, critical functionality is down, significant data loss is occurring or threatened, and no procedural workaround exists.
P2 applies when production remains available but experiences major degradation or the loss of important functionality, materially affecting part of the organization's operations. P4 covers low-impact informational requests, including questions about documentation, procedures, configuration, or account setup.
The scenario uses the defining P3 wording rather than merely describing a general support question. It therefore cannot be reduced to P4, while its non-critical and limited-impact characteristics exclude P1 and P2.
The correct priority is C. Reference: Nutanix Support Policies and Priority Definitions . NHCF alignment:
support-case creation, priority selection, and effective escalation practices.
質問 # 83
What do Nutanix Field Advisories communicate to customers?
正解：B
解説：
Nutanix Field Advisories communicate technically significant issues identified in deployed environments. An advisory typically describes the affected products or versions, the conditions under which the issue occurs, its potential operational impact and any available workaround, mitigation or permanent resolution. Option D therefore represents the advisory's purpose accurately.
Field Advisories are part of the operational knowledge used by Nutanix Support and Insights. Insights discoveries can compare cluster telemetry and configuration information against known Field Advisories to determine whether a particular environment may be exposed. Where possible, the resulting discovery includes recommended corrective action or directs the administrator to the relevant upgrade, configuration change or support process.
Product announcements and pricing information are commercial communications, not Field Advisories.
Certified hardware information is maintained through compatibility lists and platform qualification resources.
New-cluster installation procedures belong in Foundation, deployment and installation documentation.
Administrators should review applicable Field Advisories during routine health reviews and before major maintenance because an advisory can affect upgrade selection, risk assessment and remediation priority.

質問 # 84
Which component is used to present Nutanix storage as iSCSI block targets to external (non-virtualized) servers?
正解：D
解説：
A Volume Group is the Nutanix storage component used to present block storage through iSCSI to external clients, including physical or otherwise non-virtualized servers. A Volume Group contains one or more virtual disks and can be attached directly to an AHV VM or exposed through iSCSI to qualified external initiators.
External client access is controlled by defining the relevant initiator information and establishing the iSCSI connection to the Volume Group.
A storage container is a logical storage boundary used for VM data placement and for settings such as replication factor, compression, deduplication, and erasure coding. Although Volume Group data ultimately consumes capacity from a container, the container itself is not presented as an iSCSI block target.
A storage pool aggregates the physical storage resources contributed by cluster nodes. It operates below the storage-container and workload-consumption layers and is not directly assigned to an external server. A vDisk template is also not the external block-presentation object.
The examination distinction is between the underlying storage hierarchy and the consumer-facing block- storage object. Storage pools supply capacity, containers provide logical policy boundaries, and Volume Groups organize vDisks for direct or iSCSI-based attachment.
