質問 # 19
A sudden and unrecoverable hardware failure occurs at the primary site, making the Prism Element console for that cluster inaccessible. The secondary site is healthy and contains the latest replicated snapshots. Which action must the administrator take on the secondary cluster to restore the VMs?
正解：A
解説：
When a primary Nutanix site suffers a catastrophic failure, the disaster recovery plan must be executed from the recovery (secondary) site . In a legacy Protection Domain-based environment, the secondary site is in a " passive " or " standby " mode, receiving snapshots but not actively running the workloads. The traditional method to failover is using the " Activate " command (Option A), which promotes the PD and registers the VMs. However, in certain specific failure scenarios or older software versions, the secondary cluster may require a service-level reset to recognize its new role as the active master for those specific workloads.
The Cerebro service is the core component responsible for managing Protection Domains and replication metadata. If the primary site is completely inaccessible and the secondary site ' s metadata state needs refreshing to initiate recovery, restarting the Cerebro service on the secondary cluster CVMs can force a re- evaluation of all local snapshots and protection domain states. This action triggers the recovery logic, allowing the administrator to then see and activate the recovery points. While " Activate " is the goal, the first technical step in a situation where the cluster management plane is unstable or the primary is gone is ensuring the data protection services are aware of the current state. This allows the VMs to be restored from the latest snapshots, fulfilling the Recovery Time Objective (RTO) despite the complete loss of the source infrastructure.

A solution architect designs a protection policy in Prism Central to protect a specific set of VMs. The design calls for synchronous replication to two separate availability zones (AZs) simultaneously to ensure zero data loss at multiple physical locations. Which configuration limitation prevents the implementation of this specific design?
正解：D
解説：
Nutanix Disaster Recovery provides multisite replication capabilities, allowing a single cluster to protect workloads across multiple locations. However, there are specific architectural constraints regarding the type of replication schedules that can coexist within a single Protection Policy.
The primary limitation in this architect ' s design is that a single Nutanix Protection Policy supports only one synchronous replication schedule. While you can configure a policy to replicate to multiple sites using Asynchronous or NearSync schedules, you cannot natively instruct the system to perform a synchronous " 3- way " write where a single VM mirrors every I/O to two different physical destination clusters simultaneously. This is due to the extreme latency and metadata synchronization overhead that would be required to maintain zero-RPO consistency across three sites for every single write operation. Prism Central does allow pairing with more than one AZ (negating Option B), and synchronous replication is fully supported in Protection Policies (negating Option D). Therefore, to achieve the desired level of protection, the architect would need to use a combination of one synchronous schedule and additional asynchronous schedules to the second AZ, rather than attempting two simultaneous synchronous links within one policy.
質問 # 21
Which statement describes the most efficient and least disruptive method to achieve a file-level recovery without rolling back the entire VM?
正解：B
解説：
Nutanix offers several data recovery methods, but the objective of " least disruptive " and " most efficient " is specifically addressed by the Self-Service Restore (SSR) feature. SSR is powered by Nutanix Guest Tools (NGT), which must be installed on the virtual machine. This functionality allows a user or an administrator to mount a disk from a historical recovery point directly to the active, running virtual machine as a temporary drive.
Once the snapshot is mounted, the guest operating system treats it as a standard local disk, allowing the user to browse the folder structure and perform a surgical restore of only the specific files that were deleted or corrupted. This process avoids the significant overhead and downtime associated with rolling back the entire VM (Option B) or cloning the VM to a new entity (Option C), which would consume additional compute and storage resources. Option A refers to Nutanix Files (NAS) functionality, which is separate from the block- level VM snapshot recovery discussed here. By using SSR/NGT, the production environment remains online and undisturbed, and the recovery process is delegated to the level of individual files, providing the highest level of granularity and efficiency in typical day-to-day data loss scenarios.
質問 # 22
A financial institution is designing a disaster recovery solution for a business-critical application that requires a zero recovery point objective (RPO). The infrastructure team decides to implement Nutanix Metro Availability between two physical data centers (DC-Alpha and DC-Beta) interconnected by a dedicated dark fiber. What is the maximum possible network latency on this link for this configuration to function correctly?
正解：A
解説：
Nutanix Metro Availability is a continuous availability solution designed to survive a site failure with zero data loss (Zero RPO). Because it operates on a synchronous replication model, every write performed by a virtual machine must be acknowledged by both the local and the remote clusters before the write is confirmed to the application. This process introduces a " latency penalty " equal to the network Round Trip Time (RTT) between the sites.
To maintain acceptable application performance and ensure cluster stability, Nutanix enforces a strict latency limit of 5 ms RTT between the primary and secondary clusters. If the latency exceeds this 5 ms threshold, the time spent waiting for remote acknowledgments would cause severe performance degradation for high-I/O workloads, such as the SQL or Oracle databases common in financial institutions. Furthermore, high latency increases the risk of the synchronous link being " broken " during periods of high data churn. While the Witness VM (used for tie-breaking) can tolerate much higher latency (up to 200 ms), the data-path link must remain under 5 ms to satisfy the technical requirements of the Metro Availability feature and the performance expectations of Tier-1 business-critical applications.
質問 # 23
An administrator is planning a scheduled maintenance window that will temporarily interrupt network connectivity between the primary and recovery sites. Several Tier 1 VMs are protected with a Synchronous replication Protection Policy. What must the administrator do before beginning the maintenance window to prevent these VMs from becoming unresponsive without making RPO changes?
正解：C
解説：
Synchronous replication is designed for zero data loss by requiring that every write be acknowledged at both the primary and recovery sites before the application can proceed. This creates a " hard " dependency on the network link between the two clusters . If the network connectivity is interrupted (e.g., during scheduled maintenance), the primary cluster will be unable to receive acknowledgments from the remote site.
By default, if the synchronous link is broken, the primary cluster may pause I/O to the protected VMs to prevent data inconsistency, which would cause the VMs to become unresponsive to users. To prevent this during planned maintenance while ensuring that the VMs stay online at the primary site, the administrator should temporarily transition the protection mode. Changing the Protection Policy from " Synchronous " to " Asynchronous " (Option C) removes the real-time write-mirroring requirement. This allows the VMs to continue serving local I/O independently of the remote site ' s status. While this technically increases the RPO during the maintenance window, it ensures application availability. Once the maintenance is complete and network connectivity is restored, the administrator can change the policy back to Synchronous. The system will then perform a catch-up sync and return to the Zero-RPO state once the data at both sites is identical again. This operational maneuver is a standard best practice for managing " stretched " cluster environments during infrastructure updates.
