質問 # 46
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?
正解：A
解説：
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.
質問 # 47
An administrator wants to run a test failover and maps the primary production virtual network to the recovery site production virtual network for the test. What are the two most likely outcomes? (Choose two.)
正解：B、C
解説：
The fundamental purpose of a " Test Failover " in Nutanix Disaster Recovery is to provide a non-disruptive way to validate the recovery process. During this test, virtual machines are cloned from their most recent snapshots and powered on at the recovery site. If an administrator incorrectly maps the " Test Network " to the actual " Production Network " (VLAN/Subnet) at the recovery site, they create two significant risks.
First, this configuration can lead to immediate IP address conflicts. Because the test VMs have the exact same IP addresses as the live production VMs, having them active on the same logical production network will disrupt routing and potentially cause service outages for real users. Second, it defeats the " isolation " between production and test workflows. A valid DR test should occur in a " sandbox " where test applications can crash or exhibit errors without any possibility of affecting the live environment. By using the production network, the administrator is effectively running a " live " test on the production infrastructure, which is a dangerous violation of standard BCDR best practices. To avoid these outcomes, the administrator must map the test network to a dedicated, isolated VLAN or overlay network at the recovery AZ that has no physical or logical path back to the production segment.
質問 # 48
During a Test Failover, how can an administrator ensure that test VMs do not disrupt production?
正解：B
解説：
The primary purpose of a Test Failover is to validate the recovery process in a non-disruptive manner. When a VM is recovered from a snapshot during a test, it retains its original configuration, including its IP address and hostname. If this test VM were to be powered on on the same network as the live production VM, it would immediately cause a duplicate IP address conflict and potentially disrupt production services or trigger security alerts.
To prevent this disruption, Nutanix Recovery Plans allow administrators to map the production network to a " Test Network " at the recovery site. This test network is typically an " Isolated " VLAN or overlay network that has no physical or logical route back to the production environment. By using an isolated network (Option A), the test VMs can boot up, run their internal services, and even communicate with other test VMs (if placed on the same isolated segment) without any risk of interfering with real users or databases. This allows the infrastructure team to verify that the " Recovered " state is functional while the " Primary " state continues to serve the business, fulfilling the core requirement of non-disruptive testing.
質問 # 49
Which two VM disk types does Self-Service restore support? (Choose two.)
正解：A、C
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 # 50
An administrator intends to configure a NearSync replication schedule with a 15-minute Recovery Point Objective (RPO) on a hybrid 3-node cluster. The current nodes in the cluster are configured with one SSD and four HDDs each. Which cost-effective modification is required to support this specific replication schedule?
正解：B
解説：
Nutanix NearSync replication provides low RPOs (1 to 15 minutes) by using " Lightweight Snapshots " (LWS). NearSync has higher performance and hardware requirements than standard Asynchronous replication because it must handle metadata operations and data transfers much more frequently.
For a cluster to support NearSync, it must have sufficient high-performance storage to handle the additional I
/O load associated with LWS. On hybrid nodes (those with both SSDs and HDDs), Nutanix has a specific hardware requirement: each node must have at least two SSDs. This is because the NearSync LWS metadata and incoming replicated data are initially written to the SSD tier to ensure low latency and high throughput. A single SSD per node is typically insufficient to handle both active VM production I/O and the high-frequency NearSync overhead without performance degradation. Therefore, adding a second SSD to each node (Option D) is the mandatory modification. While upgrading to NVMe (Option A) or adding more nodes (Option B) would also improve performance, adding a second SSD is the minimum " cost-effective " requirement specified by Nutanix engineering for NearSync support on hybrid clusters. Meeting these hardware prerequisites is essential to ensure that the cluster can maintain the 15-minute RPO without transitioning back to an hourly schedule due to resource constraints.
