問題 #25
On an AHV host, what is the factory-configured default native Linux bridge?

  • A. br0
  • B. vs0
  • C. virbr0
  • D. ovsbr0

答案：C

解題說明：
The factory configuration of an AHV host includes a native Linux bridge named virbr0. This bridge is separate from the Open vSwitch components used for normal AHV workload and infrastructure networking.
Administrators should preserve the factory-defined bridge unless a specific Nutanix procedure instructs otherwise.
The similarly named components in the other options serve different purposes. br0 is the factory-configured default Open vSwitch bridge. It contains the physical uplink interfaces and internal ports used by the AHV networking architecture. vs0 is the default AHV virtual-switch configuration associated with br0; it is a logical virtual-switch object rather than a native Linux bridge. ovsbr0 is not the factory-default bridge name in the documented AHV configuration.
This distinction is operationally important when interpreting commands such as ovs-vsctl, Linux bridge utilities, interface listings, or network-troubleshooting output. Confusing virbr0 with br0 can lead an administrator to modify the wrong networking component and potentially disrupt host, CVM, or guest connectivity. Nutanix documentation explicitly identifies the native Linux bridge as virbr0. Reference: AHV

問題 #26
What does Nutanix Marketplace offer?

  • A. Deployment and management of Nutanix Apps and Preferred Partner Apps
  • B. Deploy NC2 clusters in the public cloud from on-premises infrastructure
  • C. Buy compute to run NC2 in a public-cloud environment
  • D. Purchase or renew Nutanix product licenses and services

答案：A

解題說明：
Nutanix Marketplace provides a centralized location within Prism Central for discovering and deploying Nutanix Apps and certified Preferred Partner Apps. Once applications are deployed, the My Apps workspace supplies a consolidated management view for their configuration, status, audit information and supported lifecycle operations.
Nutanix Apps can include platform services offered directly by Nutanix, while Preferred Partner Apps are developed and certified through collaboration between Nutanix and approved technology partners.
Marketplace simplifies deployment by presenting supported application packages and guided configuration workflows rather than requiring administrators to assemble each product manually.
Marketplace is not a cloud-compute purchasing portal. Public-cloud infrastructure used by NC2 is obtained and managed through the relevant cloud provider and the applicable Nutanix deployment workflow.
Marketplace also does not serve as the Nutanix license-renewal system; licensing and subscription management are handled through Prism licensing functions and Nutanix License Manager.
Option D precisely reflects the purpose stated in the Prism Central Admin Center documentation.

問題 #27
What resource should be used to ensure a successful upgrade of the hypervisors and AOS within a vSphere- based Nutanix cluster?

  • A. Partner Software Validation
  • B. Hardware Replacement Documentation
  • C. Nutanix Validated Designs
  • D. Compatibility and Interoperability Matrix

答案：D

解題說明：
The Nutanix Compatibility and Interoperability Matrix must be consulted before upgrading AOS or the ESXi hypervisor in a vSphere-based Nutanix cluster. The matrix identifies supported combinations of AOS releases, ESXi versions, Prism components, hardware platforms and related software. This prevents the administrator from introducing a hypervisor release that the installed AOS version does not support.
Upgrade planning must consider the current and target versions together. If the target AOS version requires a different supported hypervisor level, the administrator must follow the prescribed upgrade order. Nutanix Lifecycle Manager and one-click upgrade workflows perform compatibility checks, but the matrix remains the authoritative planning resource for confirming the intended version combination.
Nutanix Validated Designs provide architectural and deployment guidance rather than an exhaustive version- compatibility decision. Hardware replacement documentation governs component service procedures. Partner Software Validation may establish support for particular third-party products, but it does not replace Nutanix' s platform compatibility matrix for AOS and ESXi.

問題 #28
A volume group is a collection of which components?

  • A. Storage containers
  • B. Virtual disks
  • C. Controller VMs
  • D. Storage pools

答案：B

解題說明：
A Nutanix volume group is a collection of logically related virtual disks, also described as vDisks or volumes.
The group provides block-storage resources that can be attached directly to guest VMs or presented through iSCSI to supported consumers. Grouping the disks allows them to be administered, attached, protected, cloned, and managed as a related storage entity.
A storage pool aggregates physical storage capacity contributed by cluster nodes. Storage containers are logical subdivisions created within a storage pool and hold virtual disks. Consequently, a volume group can use vDisks created on Nutanix storage, but it is not a collection of pools or containers. Controller VMs run the distributed storage and cluster services on individual nodes and are unrelated to volume-group membership.
Each volume group has its own name and UUID, and administrators can add or remove virtual disks according to platform limitations. A group may be associated with one or more consumers depending on the attachment mode and supported use case. This structure is particularly suitable for applications requiring shared block devices, direct iSCSI access, or multiple related application volumes. References: Prism - Volume Group Configuration and Prism Central - Storage Components . NHCF alignment: volume groups and block-storage operations.


問題 #29
Refer to the exhibit.

A VM is experiencing poor performance at the storage level.
After reviewing the image, which action should the administrator take?

  • A. Increase the CVM memory size.
  • B. Add additional SSDs to all nodes in the cluster.
  • C. Verify whether a storage policy is affecting the VM.
  • D. Migrate the VM to another host.

答案：C

解題說明：
The exhibit displays the Cluster-wide Controller Latency metric, which represents the average time required for I/O operations to be processed by the cluster's storage controllers. Although the chart contains a latency spike, it does not establish that the cluster lacks SSD capacity or that a Controller VM is undersized. The first diagnostic action should be to determine whether a storage policy, particularly a storage Quality of Service configuration, is limiting the VM.
Storage QoS can impose an IOPS limit on a VM. When the workload reaches that limit, I/O requests are delayed to enforce the configured policy, producing elevated latency even when the physical storage subsystem has sufficient capacity. Nutanix documentation specifically notes that a maximum-IOPS configuration can cause higher latency to appear for the affected VM.
Migrating the VM to another host is unlikely to resolve a policy-enforced storage limit because Nutanix storage is distributed across the cluster. Increasing CVM memory or purchasing additional SSDs would be premature without evidence of sustained resource exhaustion. The appropriate first step is therefore to inspect the VM's applicable storage policy and QoS settings. References: Prism 7.5 - Storage Overview and Prism Central 7.5 - Storage QoS .
