質問 # 22
Which two VM disk types does Self-Service restore support? (Choose two.)
正解：A、B
解説：
Self-Service Restore (SSR) relies on the Nutanix Guest Tools (NGT) agent to mount a historical snapshot disk to the guest OS via the hypervisor ' s virtual controller. For this to work seamlessly, the guest OS and the NGT agent must support the virtual bus types used by the virtual machine.
Nutanix SSR natively supports the two most common virtual disk controller types: SCSI (VirtIO) and IDE.
These are the standard formats for most virtual disks in Nutanix AHV and ESXi environments. When a user requests a file-level restore, the system takes the vDisk from the recovery point and attaches it as a new SCSI or IDE device to the running VM, which the guest OS then scans and mounts. Conversely, specialized storage entities like Volume Groups (VGs) (Option D) and certain high-performance direct-attached PCI-based storage (Option C) are not supported by the standard SSR workflow. Volume Groups, which are often used for shared storage between VMs (like SQL Clusters), require a different recovery method because they are not part of the standard VM-centric snapshot metadata that the SSR agent can browse. Therefore, SSR is primarily designed for the standard virtual disks that form the OS and application drives of typical virtualized workloads.
質問 # 23
Which ports must remain open to support replication between two Prism Element clusters?
正解：D
解説：
Replication between Nutanix clusters involves the transfer of both actual data blocks and the metadata required to manage the consistency and scheduling of those snapshots. Two specific services running on the Controller VMs (CVMs) are responsible for these tasks: Stargate and Cerebro.
Port TCP 2009 is used by the Stargate service. Stargate is the primary I/O manager for the Nutanix cluster, and in a BCDR context, it handles the " Snapshot-on-wire " data transfer. This is the port where the actual bits of the virtual disks are sent from the source cluster to the destination cluster. Port TCP 2020 is used by the Cerebro service. Cerebro is the replication engine that handles protection domain orchestration, snapshot scheduling, and cross-site handshake operations. Without port 2020, the clusters cannot synchronize their schedules or confirm that a recovery point has been successfully stored at the remote site. While other ports like 9440 (Prism management) and 22 (SSH) are used for administrative tasks, ports 2009 and 2020 are the mandatory " data path " and " control path " ports required for the continuous and successful replication of workloads between availability zones.
質問 # 24
What is the bandwidth limit of a single Nutanix Cloud Gateway for IPSec traffic?
正解：D
解説：
The Nutanix Cloud Gateway serves as a critical bridge between on-premises Nutanix clusters and the Nutanix Cloud Availability Zone (AZ). Its primary role is to provide a secure, encrypted tunnel for replicating recovery points and managing disaster recovery orchestration metadata. When utilizing standard IPSec for this traffic, the system architecture imposes certain throughput limitations based on the processing capabilities of the gateway instance. For a single Nutanix Cloud Gateway, the maximum supported bandwidth for IPSec- encrypted traffic is 1 Gbps.
This 1 Gbps limit is an important consideration for BCDR planning, as it defines the maximum " Snapshot-on- wire " throughput available for a given protection policy. If an organization has a high data change rate (churn) that exceeds 1 Gbps of sustained replication traffic, the Recovery Point Objective (RPO) may be at risk of lag. While the physical network link might be 10 Gbps or higher, the encryption overhead of the IPSec protocol within the gateway VM is the limiting factor. To achieve higher aggregate throughput, administrators would need to deploy multiple gateways or consider high-performance direct connectivity options if available.
Understanding this 1 Gbps threshold ensures that administrators can accurately size their replication windows and manage expectations for initial seed transfers and ongoing delta synchronization to the cloud AZ.
質問 # 25
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
解説：
A multisite deployment in Nutanix Disaster Recovery allows a single primary cluster to replicate its workloads to multiple destination availability zones (AZs) for increased resilience. While a single " Protection Policy " can define the replication schedules to both recovery sites, the " Recovery Plan " is the separate object responsible for the actual orchestration of the failover.
A Recovery Plan is fundamentally a point-to-point object; it defines how to move workloads from Site A to Site B. If an administrator wants the ability to failover to either of two different recovery AZs, they must create two distinct Recovery Plans: one for AZ1 and another for AZ2. Each plan will contain the site-specific network mappings, boot sequences, and IP mappings relevant to that specific destination. If the administrator has only created a recovery plan for the first AZ, they will be able to see recovery points at both locations but will only have a " target " defined for the first site. The second AZ will not appear as a valid destination in the failover menu until its specific Recovery Plan is built and validated. This modular design ensures that each DR site can have its own customized networking and application orchestration logic.
質問 # 26
A mission-critical VM utilizing an NVIDIA vGPU profile for high-end graphical processing is replicated from a primary Nutanix cluster to a secondary disaster recovery site. After failover of a VM using an NVIDIA vGPU profile, the VM boots but hardware acceleration does not function. What action is required?
正解：A
解説：
Virtual GPUs (vGPUs) are hardware-dependent resources that are tied to specific physical GPU cards installed in the Nutanix nodes. While Nutanix Disaster Recovery can replicate the VM ' s virtual disks and general configuration, the specific mapping to a physical vGPU profile is often not automatically preserved across clusters due to potential differences in hardware availability or GPU generations at the recovery site.
When the VM fails over and boots up at the secondary site, the guest OS may see the NVIDIA driver but will find that the " backed " hardware resource is missing or incorrectly mapped, leading to a failure in hardware acceleration. To resolve this, the administrator must manually edit the VM ' s hardware settings at the recovery site and re-assign a compatible vGPU profile from the local cluster ' s available GPU resources. This post-failover cleanup task is essential for workloads like VDI (Virtual Desktop Infrastructure) or CAD applications that depend on GPU processing. Relying on NGT (Option A) or reinstalling the OS (Option B) will not fix the underlying missing hardware assignment in the hypervisor, highlighting the need for specialized knowledge when protecting VMs with specialized hardware pass-through or vGPU requirements.
