62. An administrator has noticed that a number of the virtual machines in the preferred site are showing as either failed or partitioned.
In which two ways would the administrator expect the virtual machines to respond? (Choose two.)
- A. They will be disconnected.
- B. They will be restarted in the secondary site.
- C. They will be restarted at the preferred site.
- D. They will be powered off.
- E. They will be removed from inventory.
Explaination:
Based on the information from the VMware documentation https://core.vmware.com/resource/vsan-stretched-cluster-guide#site-failure-or-network-partitions, here are insights relevant to the response of virtual machines in a vSAN Stretched Cluster during failures:
- Secondary Site Fails or Loses Network Connection: If the secondary site goes offline or becomes isolated from the preferred site and the witness host, the witness host and the preferred site continue to service storage operations, and keep data available. When the secondary site returns to the cluster, the two active sites are resynchronized.
- Preferred Site Fails or Loses Network Connection: If the preferred site goes offline or becomes isolated from the secondary site and the witness host, the secondary site continues storage operations if it remains connected to the witness host. When the preferred site returns to the cluster, the two active sites are resynchronized.
- General Operation of Stretched Clusters: In a vSAN stretched cluster configuration, both sites are active. If either site fails, vSAN uses the storage on the other site, and vSphere HA restarts any VM that must be restarted on the remaining active site
Based on these points, the most appropriate answers to your query are:
- B. They will be restarted in the secondary site.
- C. They will be restarted at the preferred site.
These options align with the behavior described in the documentation, where virtual machines are either kept running or restarted on the remaining active site (either the preferred or secondary site) in case of a site failure or network partition. The other options (A, D, E) are not directly supported by the documentation provided.
- 一位管理员注意到，首选站点中的许多虚拟机显示为失败或分区。
管理员会期望虚拟机以哪两种方式响应？（选择两个。）
- A. 它们将被断开连接。
- B. 它们将在次要站点重新启动。
- C. 它们将在首选站点重新启动。
- D. 它们将被关闭电源。
- E. 它们将从库存中移除。
解释：
根据VMware文档 https://core.vmware.com/resource/vsan-stretched-cluster-guide#site-failure-or-network-partitions 的信息，以下是vSAN拉伸集群中虚拟机在故障期间响应的相关见解：
次要站点故障或失去网络连接：如果次要站点离线或与首选站点和见证主机隔离，见证主机和首选站点继续服务存储操作，并保持数据可用。当次要站点重新加入集群时，两个活动站点将重新同步。
首选站点故障或失去网络连接：如果首选站点离线或与次要站点和见证主机隔离，如果次要站点保持与见证主机的连接，它将继续存储操作。当首选站点重新加入集群时，两个活动站点将重新同步。
拉伸集群的一般操作：在vSAN拉伸集群配置中，两个站点都是活动的。如果任一站点故障，vSAN将使用另一站点的存储，并且vSphere HA将在剩余的活动站点上重新启动任何必须重新启动的虚拟机。
根据这些点，对您的查询最合适的答案是：
- B. 它们将在次要站点重新启动。
- C. 它们将在首选站点重新启动。
这些选项符合文档中描述的行为，其中虚拟机在站点故障或网络分区的情况下，要么保持运行，要么在剩余的活动站点（首选站点或次要站点）上重新启动。其他选项（A、D、E）并不直接得到所提供文档的支持。
