質問 # 61
Which two VM disk types does Self-Service restore support? (Choose two.)
正解：B、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 # 62
A third-party backup solution is configured to use Nutanix application-consistent snapshots. Backups are failing for several Windows VMs, although crash-consistent snapshots succeed.
What is the most likely cause of the failure?
正解：A
解説：
Nutanix supports two main types of snapshots: crash-consistent and application-consistent. A crash-consistent snapshot is taken at the storage layer without any awareness of the guest OS state; it is equivalent to pulling the power plug on a server. An application-consistent snapshot is more complex because it requires the Nutanix cluster to " quiesce " the applications (such as SQL Server or Exchange) inside the guest OS, flushing pending writes to disk to ensure data integrity.
To perform this quiescence on Windows VMs, the Nutanix cluster must communicate with the Windows Volume Shadow Copy Service (VSS). This communication is handled exclusively by Nutanix Guest Tools (NGT). If NGT is not installed on the VM, or if the NGT agent is not running/communicating with the cluster, the system cannot trigger the VSS hardware provider. In this situation, any request for an " application- consistent " snapshot from a third-party backup solution will fail because the cluster lacks the necessary hooks into the guest OS. However, a " crash-consistent " snapshot will still succeed because it does not require any guest-level interaction. Therefore, when app-consistent backups fail but crash-consistent ones succeed, the most likely root cause is a missing or broken NGT installation on the affected virtual machines.
質問 # 63
Which statement describes the automatic detachment timeout period for a snapshot disk mounted to a VM using the Nutanix Guest Tools (NGT) Self-Service Restore (SSR) feature?
正解：C
解説：
Self-Service Restore (SSR) is designed to be a temporary recovery operation. When a user uses the SSR agent to mount a historical snapshot disk, that disk is attached to the VM via the hypervisor ' s virtual controller.
While it is a best practice for the user to " unmount " and " detach " the disk once they have recovered their files, the Nutanix system includes a safety mechanism to prevent these temporary disks from being left attached indefinitely.
Nutanix enforces a built-in automatic detachment timeout of 24 hours. If a disk remains attached via the SSR workflow for longer than 24 hours, the Nutanix orchestration engine will automatically trigger a detachment task to clean up the VM ' s configuration. This is essential for maintaining cluster " hygiene, " as stale snapshots attached to VMs can interfere with future backup operations, prevent VM migrations (vMotion), or lead to unnecessary storage overhead if the snapshots are kept " locked " by the attachment. Understanding this 24-hour timeout helps administrators reassure users that they have a full day to perform their recovery tasks while ensuring the infrastructure team that the environment will automatically revert to a clean state without manual intervention. This balance of user flexibility and system automation is a hallmark of the Nutanix BCDR design.

質問 # 64
During routine monitoring, an administrator notices that replication from the primary Nutanix cluster to the recovery cluster has stopped. New recovery points are not being created, and the DR dashboard shows replication errors. Investigation reveals:
* The primary and recovery clusters are both online and healthy.
* Network segmentation was recently enabled to isolate replication traffic from other workloads.
* No recent changes were made to firewall rules, protection policies or RPO settings.
Which action should the administrator take first to investigate the replication failure?
正解：B
解説：
In a Nutanix environment, replication health is heavily dependent on the available bandwidth and the consistency of the network path between the source and target sites. When replication fails following an infrastructure change like network segmentation, it often indicates that the system is unable to sustain the current data change rate over the new path. While verifying ports (Option C) is a logical infrastructure step, the provided answer emphasizes managing the replication load by increasing the Recovery Point Objective (RPO) interval. Increasing the RPO (e.g., from 1 hour to 4 hours) reduces the frequency of snapshot transfers, which can help determine if the replication engine (Cerebro) can successfully complete a transfer when given a longer window or reduced pressure. If increasing the RPO resolves the failure, the administrator can conclude that the network change introduced a bottleneck or limited throughput that is insufficient for the original " heavy " schedule. This diagnostic step helps differentiate between a total connectivity blackout and a performance-related failure caused by the newly implemented network segmentation. Once the baseline replication is restored at a higher RPO, the administrator can then proceed to optimize the network or firewall settings to support the more aggressive RPO requirements originally set by the business.
質問 # 65
An organization requires a maximum data loss of 15 minutes for a Tier-1 application running on Nutanix AHV. Which configuration best meets this requirement?
正解：A
解説：
This question evaluates the administrator ' s ability to map business RPO (Recovery Point Objective) requirements to the appropriate Nutanix technology. A requirement for " maximum 15 minutes of data loss " means the system must replicate data at least every 15 minutes. Nutanix offers two primary ways to achieve this: traditional Asynchronous replication and Nearsync replication. While Async (Option D) can technically be configured for a 15-minute interval, it relies on standard, full snapshots which can be heavy and resource- intensive, potentially leading to performance lag if the data churn is high. Nearsync Replication (Option B) is specifically designed for these low-RPO scenarios (from 20 seconds up to 15 minutes) by using " Lightweight Snapshots " (LWS). LWS minimize the storage and I/O overhead compared to traditional snapshots, making Nearsync the more reliable and robust choice for Tier-1 applications. Furthermore, Nearsync is built to handle the constant, high-frequency data transfers required to maintain a strict 15-minute window without impacting application performance. Therefore, Nearsync with a 15-minute RPO is the " best " configuration because it is the purpose-built solution for the stated performance and data protection goals.
