質問 # 104
Which two Data Protection technologies are compatible with Self-Service Restore? (Choose two.)
正解：C
解説：
Self-Service Restore (SSR) is a Nutanix guest-level feature that empowers users to mount snapshots as local drives to recover individual files without administrative intervention. For SSR to function, the underlying data protection mechanism must support the specific metadata and disk-attachment hooks required by Nutanix Guest Tools (NGT). Asynchronous (Async) replication schedules are a primary supported technology for SSR because they create standard, persistent recovery points that are easily indexed by the SSR agent within the guest OS. While the question asks to " Choose two, " it is important to note that Nutanix also generally supports SSR for Synchronous replication (Option C), as both methods produce the point-in-time vDisk snapshots necessary for the mounting process.
Conversely, certain high-frequency technologies like NearSync (at very low RPOs) or complex storage entities like Volume Groups (VGs) have historically faced limitations with the SSR mounting workflow due to the way metadata is handled or how disks are presented to the hypervisor. In a production environment, an administrator must ensure that NGT is fully functional on the VM and that the VM is part of a compatible Protection Policy to enable the SSR " snapshot-to-drive " mapping. This capability is essential for balancing operational efficiency with user-led data recovery, as it offloads simple " deleted file " requests from the infrastructure team while leveraging the existing BCDR snapshot architecture.
質問 # 105
An administrator managing critical VMs has been tasked with designing a Disaster Recovery solution where the VMs are brought up on the target cluster if the source cluster experience any issues. The failover needs to be triggered without any user intervention and with minimal downtime. What automatic failure execution solution is best suited?
正解：D
解説：
To achieve the goal of " minimal downtime " and " no user intervention, " a zero-RPO solution with automated failover capabilities is required. In the Nutanix ecosystem, this is accomplished through Synchronous Replication. Unlike Asynchronous or NearSync replication, which rely on snapshot intervals and manual failover triggers, Synchronous replication ensures that data is written to both the local and remote clusters simultaneously. This architecture provides the foundation for zero data loss during a site failure.
However, the " automatic " part of the requirement is fulfilled by the addition of a Witness VM. Without a Witness, a secondary cluster cannot independently determine if the primary cluster has actually failed or if there is merely a network partition. In a " no witness " scenario (Option C), the secondary cluster stays in a passive state to prevent " split-brain " data corruption, requiring an administrator to manually promote the storage. By deploying a Witness VM at a third, independent site, the secondary cluster can communicate with the Witness to " acquire the lock " on the protection domain. Once the Witness confirms the primary site is unreachable, the orchestrator automatically promotes the secondary container and powers on the VMs. This combined solution of a Synchronous Protection Policy and a Witness VM provides the highest level of availability and the fastest possible recovery without requiring human action during the disaster event.
質問 # 106
An organization requires strict control over data destruction. An administrator configures an Approval Policy for DR snapshots to prevent accidental deletion. A user attempts to delete a recovery point protected by this policy. What is the immediate outcome of this deletion attempt within the Prism Central interface?
正解：B
解説：
Security and compliance are critical components of a Business Continuity strategy, particularly regarding the integrity of backups and snapshots. To prevent accidental or malicious deletion of critical recovery points, Nutanix Prism Central allows administrators to configure " Approval Policies " . These policies enforce a " four-eyes " principle where certain high-risk actions require validation by a second authorized user.
When an Approval Policy is active for DR snapshots, and a user attempts a deletion, the system does not execute the command immediately. Instead, the Nutanix orchestration engine captures the request and creates a " Pending Approval " task. The user who initiated the request will see the status update in the Task console, and an notification is sent to the designated " Approvers " . The snapshot remains fully protected and available for recovery until an authorized approver reviews and explicitly grants permission for the deletion.
This mechanism provides a vital layer of defense against ransomware or administrative errors that could otherwise lead to the loss of a known-good recovery state. By integrating approval workflows into the storage management layer, Nutanix ensures that data destruction is a deliberate and verified process, meeting the strict control requirements of modern enterprises.
質問 # 107
A Protection Policy is configured with a Nearsync replication schedule (15-minute RPO). An administrator observes that the system has temporarily transitioned to an hourly replication schedule. Which scenario would cause this automatic transition from Nearsync to Asynchronous (hourly) replication?
正解：A
解説：
NearSync replication is a Nutanix technology that provides RPOs as low as 1 minute by using " Lightweight Snapshots " (LWS). However, NearSync has specific operational requirements to maintain its aggressive schedule . If the system detects that it cannot maintain the 15-minute RPO using lightweight snapshots, it will automatically " downshift " to a standard Asynchronous (hourly) replication mode to ensure that protection is not lost entirely.
One of the most common triggers for this temporary transition is the addition of a new virtual machine to the category associated with the Protection Policy. When a new VM is added, the Nutanix cluster must perform a
" full initial sync " (also known as a seed replication) to transfer all the VM ' s data to the remote site. Because a full seed replication involves transferring much more data than a standard delta update, it often exceeds the time window and processing capabilities of the NearSync LWS engine. To handle this large data transfer safely, the system switches to the Async (hourly) schedule, which uses more robust but slower snapshot mechanisms. Once the initial sync of the new VM is complete and the clusters are in a " consistent " state, the system will automatically attempt to " upshift " back to the NearSync schedule to restore the 15-minute RPO.
This behavior ensures that the system handles growth and changes in the environment while maintaining the highest possible level of protection without administrative intervention.
質問 # 108
A VM is protected in an Async Protection Policy with a schedule for every 1 hour. The replications are completing successfully every hour. The VM hosts a critical application and cannot afford any data loss. The administrator unprotects the VM from the Async Policy and protects the VM in a Synchronous policy. The administrator also notices that the VM is not entering the " Sync " state and is stuck in syncing for a long time. The administrator notices the error in the logs:
Enabling stretch for entity TestVM failed while notifying vm service due to error Acropolis failed to handle VmSyncRepEnable request for VM TestVM Failed to connect to remote Anduril What port needs to be allowed between the clusters to fix the issue?
正解：D
解説：
In a Nutanix environment, Synchronous replication (including Metro Availability and Synchronous Protection Policies) relies on a specialized service known as Anduril to manage the real-time mirroring and state transitions of virtual machines. While standard asynchronous replication primarily uses ports 2009 (Stargate) for data transfer and 2020 (Cerebro) for metadata and replication management, synchronous replication introduces additional requirements for low-latency communication between the Anduril services on the source and destination clusters.
The error message " Failed to connect to remote Anduril " specifically indicates that the local cluster ' s management plane is unable to communicate with the remote cluster ' s synchronous replication manager.
TCP port 2036 is the dedicated port for cross-cluster communication between Anduril services. This port is used to negotiate the " stretch " of the VM across sites, coordinate the initial sync, and maintain the health heartbeat required for high-availability failover decisions. If port 2036 is blocked by a physical or virtual firewall between the clusters, the " VmSyncRepEnable " request will time out or fail, preventing the VM from ever entering the " Sync " (Active-Active) state. Troubleshooting synchronous replication always begins with verifying that the 5ms latency requirement is met and that port 2036 is open alongside the standard ports 2009 and 2020 to ensure both data and control traffic can flow without interruption between availability zones.
