An organization uses Nutanix Disaster Recovery with automatic virtual network creation in the Nutanix Cloud AZ. After a successful failback operation from the Nutanix Cloud AZ to the on-premises site, what is the expected behavior regarding the dynamically created virtual networks at the recovery site?
正解：D
解説：
Nutanix Disaster Recovery to the Cloud is built on the principle of automation and resource optimization.
When a failover to a Nutanix Cloud Availability Zone (AZ) occurs, the orchestration engine can dynamically provision virtual networks to ensure recovered VMs have immediate connectivity. These networks are temporary infrastructure components required only while the workloads are running in the cloud. Once the primary on-premises site is restored and a failback is successfully executed, the VMs are migrated back to their original home. At this point, the dynamically created virtual networks at the cloud recovery site no longer host any active entities. The Nutanix orchestration engine is designed to automatically clean up these ephemeral resources (Option B) to prevent " infrastructure sprawl " and to ensure the customer is not billed for unused networking components in the cloud. This automated cleanup is a core feature of the Nutanix Cloud AZ workflow, allowing administrators to focus on stabilizing production rather than performing manual housekeeping tasks on the recovery site. This cycle of dynamic provisioning and automated cleanup ensures that the DR environment is always " right-sized " and ready for the next event.

An administrator has set up asynchronous replication between the Marseille and Paris clusters for the VMs in the FIN-PROD storage container. After a planned production failover from Paris to Marseille, the administrator noticed that the VMs were scattered across all the storage containers in the Marseille cluster.
Which statement is true regarding this scenario?
正解：C
解説：
In modern Nutanix Disaster Recovery (using Prism Central-based Protection Policies), storage placement is often governed by Storage Policies rather than simple container-to-container mapping. Storage Policies use Nutanix Categories to determine where a VM should be placed to meet performance or compliance requirements. In this scenario, the VMs were successfully replicated and recovered, but they were placed in " all the storage containers " rather than the intended FIN-PROD container at the Marseille site. This indicates that while the data arrived, the " destination placement rules " were missing. If a storage policy was created on the Paris cluster to keep these VMs in FIN-PROD but that policy was not mirrored or assigned at the Marseille cluster, the system defaults to the Acropolis Dynamic Scheduler (ADS) placement. ADS will distribute the VMs across all available containers to balance load and capacity, leading to the " scattered " result observed. To resolve this and ensure consistent failover behavior, the administrator must ensure that both the categories and the corresponding storage policies are identical and active at both availability zones.
While a missing container (Option C) would typically cause a replication failure rather than scattered recovery, a missing storage policy specifically explains the lack of orchestrated placement during the failover event.

A Veeam backup job is configured to use Nutanix application-consistent snapshots for several Windows VMs. Crash-consistent snapshots succeed, but Veeam reports that application-consistent snapshots fail with errors related to VSS processing. Upon investigation, the administrator confirms:
* The VMs are powered on.
* Network connectivity between the backup server and cluster is healthy.
Which configuration should the administrator verify to resolve the issue?
正解：A
解説：
Application-consistent snapshots are critical for ensuring data integrity for transactional workloads, such as databases. In a Nutanix AHV or ESXi environment, the cluster achieves application consistency by communicating with the guest operating system ' s Volume Shadow Copy Service (VSS). This communication is facilitated exclusively through Nutanix Guest Tools (NGT). When NGT is installed and enabled, it provides a VSS hardware provider that Nutanix uses to " quiesce " (pause/stabilize) the application
' s I/O and flush pending writes to the disk before the snapshot is taken. If crash-consistent snapshots are working but application-consistent ones are failing, it is a primary indicator that the VSS hooks provided by NGT are either missing, outdated, or not communicating correctly with the Nutanix cluster services. Without NGT, the system cannot verify the internal state of the guest OS, leading to VSS processing errors in third- party backup solutions like Veeam or Commvault. Ensuring NGT is installed and the NGT agent is running within the guest VM is the mandatory first step to resolving any snapshot failure involving application-level consistency.
質問 # 95
An administrator configures a protection policy that replicates workloads to two different recovery AZs (multisite deployment). Replication to both recovery AZs is successful. However, when attempting to perform failover to the second recovery AZ, the administrator cannot select it as a failover target.
Which setup step was most likely missed?
正解：B
質問 # 96
An administrator executes a Recovery Plan for a set of high-performance VMs configured with SR-IOV network adapters. The VMs failover successfully to the Recovery Cluster.
What is the state of these VMs immediately after the planned failover completes?
正解：A
解説：
Single Root I/O Virtualization (SR-IOV) allows a virtual machine to bypass the hypervisor ' s virtual switch and communicate directly with a physical network adapter ' s virtual functions. This is commonly used for high-performance applications that require extremely low latency and high throughput. However, SR-IOV creates a " hard " dependency between the virtual machine and the specific physical hardware (NIC) of the host it is running on.
Disaster Recovery involves moving a VM to an entirely different cluster, which likely has different physical network adapters or a different SR-IOV configuration. Nutanix Disaster Recovery orchestration is designed to ensure that VMs can always boot at the recovery site, even if specialized hardware resources are unavailable.
For VMs configured with SR-IOV, the recovery process includes a built-in fallback mechanism. During failover, the system will recover the VM and power it on, but it will disable the SR-IOV attachment. To ensure connectivity, it automatically adds or falls back to a standard virtio-net virtual adapter. This allows the VM to have network access immediately, though at a potentially lower performance level. The administrator must then manually re-configure SR-IOV at the recovery site if the local hardware supports it. This design prioritizes service availability (powering on and communicating) over specialized hardware performance during a disaster recovery event.
