質問 # 46
Which log file should an administrator review to ensure consistent connectivity stability between primary and remote disaster recovery sites?
正解：B
解説：
The Nutanix architecture relies on specialized services running on each Controller VM (CVM) to handle specific cluster operations. The " Cerebro " service is the primary engine responsible for data protection and replication tasks across the Nutanix cluster. It manages recovery points, snapshot schedules, and the actual transfer of data between the local cluster and remote sites. Consequently, the cerebro.INFO log file is the most vital resource for an administrator troubleshooting replication health or site-to-site connectivity. This log records critical events such as the start and completion of replication jobs, handshake failures between clusters, and timeout errors during snapshot transfers. If an administrator notices that replication is " hung " or failing consistently, cerebro.INFO provides the granular detail needed to see if the issue is a network timeout, a remote service unavailability, or a metadata synchronization error. Reviewing this log helps ensure that the connection stability is maintained and that any deviations in replication performance are identified before they impact the Recovery Point Objective (RPO). Other logs like genesis.out (Option B) are more focused on service startup and configuration rather than the ongoing health of the BCDR replication stream.

The Disaster Recovery dashboard in Prism Central shows that the protection domain is out of sync and new recovery points are no longer being created at the recovery site. No recent changes were made to the protection policy configuration or RPO settings. During initial troubleshooting, an administrator has observed the following:
* Production VMs are running normally at the primary site.
* The recovery cluster is reachable from Prism Central.
* No storage capacity alerts are seen on either cluster.
* A recent network change was implemented to enable network segmentation between clusters.
* New firewall rules were introduced recently as part of a security hardening effort.
Which action should the administrator take first when evaluating this issue?
正解：B
解説：
Network segmentation is a powerful Nutanix feature used to isolate replication and storage traffic from standard management traffic. However, implementing this in a " brownfield " environment-where replication is already active-requires careful coordination. In this scenario, the replication failure coincides with the implementation of network segmentation and new firewall rules. The administrator ' s first action must be to verify if segmentation was enabled while replication was actively running. If segmentation is enabled on one site without a matching configuration on the remote cluster, or if the services (Cerebro
/Stargate) were not properly restarted to bind to the new interfaces, the replication stream will " hang " .
Furthermore, enabling segmentation changes the source and destination IP addresses used for replication traffic. If these new segmented IP addresses were not whitelisted in the recent firewall hardening effort, all " Snapshot-on-wire " traffic will be dropped. By verifying the segmentation state first, the administrator can determine if the network plumbing is consistent across both sites. Recreating policies (Option A) or triggering failover (Option C) would not resolve an underlying network isolation issue and would likely result in further failures until the segmentation and firewall rules are properly aligned.
質問 # 48
An administrator is testing the failover scenarios from a source availability zone (AZ1) to a destination availability zone (AZ2). The administrator successfully performs an unplanned failover from AZ1 to AZ2.
The administrator then immediately tries to use the unplanned failover option to fail the VM back to AZ1, but does not see the VM listed under Recovery Plan. What could be the cause?
正解：C
解説：
Failback is a critical phase of the disaster recovery lifecycle where workloads are returned to their original primary site. When an " Unplanned Failover " is executed, the system assumes the primary site is gone or unmanaged. Once the primary site (AZ1) is restored, the administrator cannot simply " re-run " the failover in reverse without preparing the source site. The " Clean up of Entities " (Option C) is a mandatory step that must be performed on the original primary cluster after it returns to a healthy state. This process clears the stale VM registrations and metadata that existed prior to the outage, signaling to the Nutanix orchestrator that AZ1 is now ready to re-receive the workloads. Until this cleanup is completed, the Recovery Plan will not list the VMs as eligible for failback because it still detects the " ghost " of the VM at the destination. While reverse replication (Option B) is also necessary to prevent data loss during failback, the reason the VMs are entirely missing from the Recovery Plan interface during the initial failback attempt is the lack of entity cleanup. Performing this cleanup ensures a smooth transition back to primary production without metadata conflicts or registration errors.
質問 # 49
A company ' s two clusters are part of the same availability zone. Prism Central, which holds the protection policy configuration and recovery plans, is located on Cluster A and protected by the Prism Central Backup and Restore mechanism. What is the first step to take to execute a disaster recovery plan on the datacenter hosting Cluster A?
正解：D
解説：
Prism Central (PC) acts as the centralized control plane for Nutanix Disaster Recovery, storing the critical metadata for Protection Policies and Recovery Plans. If the cluster hosting the Prism Central instance suffers a total failure, the " brain " of the DR orchestration is lost, and the administrator cannot trigger the Recovery Plans through the usual interface. To address this risk, Nutanix provides the " Prism Central Backup and Restore " feature, which replicates the PC metadata to a remote cluster managed by Prism Element (PE). In a disaster scenario affecting Cluster A, the first and most critical step is to recover the management plane. The administrator must log into Prism Element on the surviving cluster and use the native recovery workflow to restore the Prism Central instance from the most recent backup. Once the PC instance is restored and booted on the surviving cluster, it will once again have access to the Recovery Plans and Protection Policies. Only after the management plane is restored can the administrator then initiate the " Unplanned Failover " tasks to bring up the protected workloads. This process ensures that the RTO is kept low by restoring the automated orchestrator rather than manually re-creating policies and plans on a new instance (Option B).
質問 # 50
An administrator configures a VM-VM Anti-Affinity policy for a web application cluster to ensure high availability. The application is protected by a Protection Policy in Prism Central. A failover occurs, moving the VMs to the recovery site.
What determines whether the VM-VM Anti-Affinity rules are active on the recovery site?
正解：D
解説：
VM-VM Anti-Affinity rules are used in Nutanix to ensure that specific virtual machines (such as the nodes of a database cluster or redundant web servers) never run on the same physical host, thereby protecting the application from a single host failure. These rules are typically managed through Prism Central (PC) in a modern deployment.
However, in the context of Disaster Recovery (DR) between two different clusters or availability zones, there is a technical limitation regarding the replication of these affinity policies. While the virtual machine ' s data and primary metadata (CPU, RAM, Disks) are replicated by the Cerebro service, the affinity rules are often considered local cluster constraints. In many versions of Nutanix Disaster Recovery (specifically the initial iterations of Leap/Prism Central-based DR), these affinity policies are not natively " synchronized " or enforced at the recovery site during a failover. This means that when the VMs are recovered at the destination cluster, the hypervisor ' s dynamic scheduler (ADS) may place them on the same host if that host has the most available resources. To maintain anti-affinity at the recovery site, an administrator would typically need to manually recreate the affinity policies at the destination AZ or use specialized orchestration scripts.
Understanding this limitation is vital for ensuring that high-availability requirements are still met after a disaster recovery event has occurred.
