最新的 Nutanix NCP-BC NCP-BC-7.5 免費考試真題 (Q23-Q28):

問題 #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?

答案：D

解題說明：
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.


問題 #24
Which log file should an administrator review to ensure consistent connectivity stability between primary and remote disaster recovery sites?

答案：A

解題說明：
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.


問題 #25
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?

答案：A

解題說明：
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).


問題 #26
An organization has two Nutanix clusters managed by a single Prism Central (PC) instance. They intend to implement Synchronous Replication between the sites. During a failover test, the administrator notices that automatic failover does not occur when the primary site ' s storage becomes unavailable. What is the most likely cause of this behavior based on an analysis of the requirements?

答案：D

解題說明：
In a Nutanix Synchronous Replication or Metro Availability setup, data is mirrored in real-time, but the " intelligence " required to automate a failover resides outside of the two primary clusters. Without a Witness VM (Option C), the secondary cluster cannot distinguish between a total primary site failure and a simple network partition between the two data centers. If the clusters lose communication but there is no Witness to act as an independent tie-breaker, the secondary cluster will stay in a " Standby " state and will not automatically " promote " its storage to " Active " or power on the VMs. This is a safety mechanism to prevent " split-brain " where two clusters might try to serve the same data, leading to corruption. To enable automatic failover, a Witness VM must be deployed at a third, independent site and registered to both clusters. The Witness allows the secondary site to verify that the primary site has indeed failed; once verified, the Witness grants the " lock " to the secondary site, allowing the automated failover process to begin. Thus, the lack of a Witness is the " most likely cause " for why a failover test would fail to trigger automatically during a storage or site outage.


問題 #27
An administrator is concerned about the operational overhead of manually creating and managing categories across both the primary and recovery sites to ensure Recovery Plans function correctly during failover and failback. What Nutanix Disaster Recovery behavior minimizes this concern?

答案：A

解題說明：
Nutanix Disaster Recovery (formerly known as Leap) utilizes Prism Central-based " Categories " to group virtual machines for protection. These categories are used within Protection Policies to determine replication schedules and within Recovery Plans to determine power-on sequences and network mappings. A common operational concern is the need to manually replicate these category definitions across different availability zones (AZs).
To reduce this operational overhead, Nutanix has implemented an automatic synchronization mechanism.
When an administrator creates a Recovery Plan in Prism Central and specifies certain categories for failover, the system automatically synchronizes the definition and metadata of those categories to the paired recovery AZ. This ensures that if the primary Prism Central instance becomes unavailable, the recovery site already possesses the necessary grouping logic to identify and recover the correct virtual machines . This " policy- driven " approach ensures consistency across sites and eliminates the risk of human error associated with manual configuration (Option B). By automating the lifecycle of categories between paired sites, Nutanix ensures that the disaster recovery environment is always aligned with the production environment, allowing for seamless failover and failback operations without the need for repetitive administrative tasks.
