83. Following the deployment of a new all-flash vSAN 7.0 U1 stretched cluster, an administrator has been tasked with decommissioning the existing hybrid vSAN 6.7 U3 stretched cluster since the hardware is becoming end-of-life. In addition to Virtual Machine storage, the hybrid vSAN cluster also provides iSCSI target services.
The administrator has completed the following tasks：
- All workloads have been successfully migrated to the new vSAN stretched cluster.
- The iSCSI target service has been enabled on the new vSAN stretched cluster.
Which three additional tasks should the administrator complete to properly decommission the hybrid vSAN stretched cluster and ensure that all data is removed? (Choose three.)
- A. Run the Wipe-Disk Power CLI command to securely wipe any data.
- B. Disable vSAN File Services.
- C. Convert the vSAN stretched cluster into a vSAN standard cluster.
- D. Remove any disk groups before decommissioning the vSAN data nodes.
- E. Disable the vSAN performance service.
- F. Ensure all data has been evacuated from the vSAN cluster.
Explaination:
To properly decommission the hybrid vSAN 6.7 U3 stretched cluster and ensure all data is removed after migrating to the new all-flash vSAN 7.0 U1 stretched cluster, the administrator should complete the following three tasks out of the options provided:
A. Run the Wipe-Disk PowerCLI command to securely wipe any data: This is an essential step in the decommissioning process. The Wipe-Disk PowerCLI command is used to securely erase all data on the disks that were part of the vSAN cluster. This ensures that no residual data is left behind on the storage devices, which is crucial for data security and compliance with data protection regulations.
D. Remove any disk groups before decommissioning the vSAN data nodes: Before the physical decommissioning of the vSAN nodes, it’s important to remove the disk groups from the vSAN cluster. This step helps to ensure that the cluster is no longer utilizing the storage resources and that the disks are ready to be wiped or repurposed.
F. Ensure all data has been evacuated from the vSAN cluster: This is a critical step to confirm before decommissioning any storage cluster. The administrator needs to ensure that all data, including Virtual Machine storage and iSCSI target data, has been successfully migrated to the new cluster and that no data remains on the old cluster. This verification avoids any potential data loss.
The other options, while they might be relevant in certain contexts, are not as critical for ensuring that all data is removed in the decommissioning process:
- B. Disable vSAN File Services: This might be necessary if the service was in use, but it is not specified as a requirement in the scenario provided.
- C. Convert the vSAN stretched cluster into a vSAN standard cluster: This is not relevant to decommissioning, as the cluster is being decommissioned altogether.
- E. Disable the vSAN performance service: While this might be a standard procedure in decommissioning, it does not directly contribute to the removal of data.
83. 在部署了新的全闪存vSAN 7.0 U1弹性集群之后，管理员被安排负责退役现有的混合vSAN 6.7 U3弹性集群，因为硬件即将到达生命周期的尽头。除了虚拟机存储外，混合vSAN集群还提供iSCSI目标服务。 管理员已经完成了以下任务：
- 所有工作负载已成功迁移到新的vSAN弹性集群。
- 已在新的vSAN弹性集群上启用iSCSI目标服务。
管理员为正确退役混合vSAN弹性集群并确保所有数据被移除还需要完成哪三项任务？（选择三项。）
- A. 运行Wipe-Disk PowerCLI命令以安全擦除任何数据。
- B. 禁用vSAN文件服务。
- C. 将vSAN弹性集群转换为vSAN标准集群。
- D. 在退役vSAN数据节点之前移除任何磁盘组。
- E. 禁用vSAN性能服务。
- F. 确保所有数据已从vSAN集群中撤出。
为了正确退役混合vSAN 6.7 U3弹性集群并在迁移到新的全闪存vSAN 7.0 U1弹性集群后确保所有数据被移除，管理员应完成以下三项任务：
A. 运行Wipe-Disk PowerCLI命令以安全擦除任何数据：这是退役过程中的一个重要步骤。Wipe-Disk PowerCLI命令用于安全地擦除曾经是vSAN集群一部分的磁盘上的所有数据。这确保了存储设备上没有遗留数据，这对于数据安全和遵守数据保护法规至关重要。
D. 在退役vSAN数据节点之前移除任何磁盘组：在物理退役vSAN节点之前，重要的是要从vSAN集群中移除磁盘组。这一步有助于确保集群不再使用存储资源，并且磁盘准备好被擦除或重新利用。
F. 确保所有数据已从vSAN集群中撤出：这是在退役任何存储集群之前确认的关键步骤。管理员需要确保所有数据，包括虚拟机存储和iSCSI目标数据，都已成功迁移到新集群，并且旧集群上没有剩余数据。这种验证避免了任何潜在的数据丢失。
其他选项虽然在某些情境下可能相关，但对于确保退役过程中移除所有数据来说并不那么关键：
B. 禁用vSAN文件服务：如果该服务在使用中，这可能是必要的，但在所提供的情景中并未指定为要求。 C. 将vSAN弹性集群转换为vSAN标准集群：这与退役无关，因为整个集群正在被退役。 E. 禁用vSAN性能服务：虽然这可能是退役的标准程序，但它不直接有助于数据的移除。
