23. Frage
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?
Antwort: B
Begründung:
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.
24. Frage
A remote office deployment consists of a two-node Nutanix hybrid cluster. An administrator attempts to configure a protection domain with a 5-minute RPO (Nearsync) replicating to a central datacenter.
Why is the administrator unable to successfully configure this Nearsync schedule?
Antwort: B
Begründung:
Nutanix NearSync replication provides a middle ground between traditional asynchronous replication and synchronous mirroring, offering RPOs as low as 1 minute using Lightweight Snapshots (LWS). However, the LWS mechanism and the high-frequency metadata operations required to maintain a 1-to-15 minute RPO have specific hardware and cluster-level requirements.
One of the strict prerequisites for enabling NearSync is the cluster size. Nutanix requires a minimum of a three-node cluster for NearSync replication. This is because the system must have enough resources to distribute the LWS metadata and handle the increased I/O overhead without compromising the cluster ' s availability or performance. In a two-node cluster (which is common for small ROBO deployments), the system does not meet the minimum redundancy and resource thresholds required for the NearSync engine to operate reliably. While two-node clusters support standard Asynchronous replication (with a 60-minute RPO or higher), they are restricted from using the NearSync lightweight snapshot engine. An administrator attempting to set a 5-minute RPO on a two-node cluster will find the option either grayed out or the task will fail validation. To achieve a 5-minute RPO, the organization would need to expand the remote office cluster to at least three nodes or settle for a higher RPO supported by standard asynchronous replication on the existing hardware.
25. Frage
In the case of a protection domain containing more than 500 VMs, what is the first step an engineer must take before migrating to Prism Central-based protection policies while ensuring all VMs remain protected?
Antwort: D
Begründung:
Migrating from legacy Protection Domains to modern Prism Central Protection Policies is a recommended practice for scaling DR management. However, large environments must account for architectural limits during this transition. A Nutanix cluster has specific maximum thresholds for the number of entities (VMs) that can be contained within a single Protection Domain, and similar limits exist for the initial " handoff " to Prism Central.
If a single legacy Protection Domain contains more than 500 VMs, attempting to migrate it as a single unit can lead to timeouts, metadata synchronization failures, and potential gaps in protection. To ensure that all VMs remain consistently protected during the migration, the first step is to " split " the existing large Protection Domain into multiple smaller, more manageable ones. For example, an administrator might split a
600-VM domain into three 200-VM domains. This reduction in " entity density " allows the Nutanix Cerebro and Prism Central services to process the migration tasks more efficiently without hitting resource contention or task timeout limits. Once the VMs are organized into these smaller groups, they can be systematically unlinked from the legacy domains and added to the new PC-based Protection Policies. This phased and controlled approach minimizes risk and ensures that a valid recovery point always exists for every VM throughout the entire migration lifecycle.
26. Frage
A deployment uses native encryption for replication traffic between two clusters. An administrator subsequently enables network segmentation to isolate this traffic. Which specific maintenance step must be performed to ensure the encrypted replication functions correctly on the new segmented network?
Antwort: C
Begründung:
Nutanix allows for the encryption of replication traffic " on the wire " using IPSec tunnels between clusters.
When an administrator enables network segmentation for Disaster Recovery, the replication traffic is moved from the default management network to a new, dedicated subnet and set of virtual interfaces.
Because the native replication encryption relies on IPSec gateways to secure the communication, the underlying VPN configuration must be aware of the network paths it is protecting. If the traffic is now originating from a new segmented subnet, the IPSec VPN gateway configuration at both the primary and recovery sites must be updated to include these new subnet ranges. If this step is missed, the encrypted tunnel will not recognize the segmented traffic as valid for the VPN, causing replication to fail even if the physical network is reachable. Regenerating KMS tokens (Option C) relates to data-at-rest encryption on physical drives, not traffic-in-transit. Restarting services (Option D) might be part of the general segmentation workflow, but the specific requirement for " encrypted replication " stability in this context is the alignment of the IPSec VPN policy with the new segmented network topology.
27. Frage
An administrator has been tasked with configuring a Nutanix replication solution that provides an RPO of zero. Which solution should the administrator choose?
Antwort: B
Begründung:
The Recovery Point Objective (RPO) is a measure of how much data an organization can afford to lose during an outage. An RPO of zero means that absolutely no data loss is tolerated; every write performed at the primary site must be safely committed to the recovery site before the application receives a confirmation. In the Nutanix portfolio, Synchronous Replication (Option A) is the only technology that guarantees this level of data protection. It mirrors every write in real-time between two clusters, ensuring they are always in perfect synchronization. In contrast, Nearsync Replication (Option B) allows for very low RPOs (as low as 20 seconds to 1 minute), but it is still fundamentally an asynchronous process using lightweight snapshots, meaning some " data-in-flight " could be lost. Async Replication (Option C) typically involves RPOs of one hour or more and is used for less critical workloads. Cloud Connect (Option D) is a legacy feature for off-site backup and does not support zero-RPO requirements. Synchronous Replication is the " gold standard " for Tier-1, mission-critical applications where data integrity and zero loss are the primary business requirements, provided the network latency between sites is 5ms or less.
