37、A VMkernel port is labelled PROD01 and uses the default TCP/IP stack. Currently， this VMkernel port is configured for supporting live virtual machine (VM) migrations.Which configuration change should the administrator make to isolate live VM migration traffic from other network traffic?

解析：解析:The administrator must create a forward DNS A record for the vCenter Server (vcsa01)， which maps the FQDN of the vCenter Server to its IP address. The administrator must also create a reverse DNS A record for the ESXi Host server (esx01)， which maps the IP address of the ESXi Host to its FQDN. These DNS records are required for name resolution and certificate validation during the deployment of the vCenter Server Appliance.

解析：解析: Option D is correct because it allows the administrator to delete only the latest version of the template by reverting to the previous version and then deleting the current version. Option A is incorrect because it deletes the entire template and not just the latest version. Option B is incorrect because it renames the previous version to the current version and does not delete anything. Option C is incorrect because it checks out the latest version and deletes it from the folder， but not from the library.选项D是正确的，因为它允许管理员通过恢复到先前版本然后删除当前版本来仅删除模板的最新版本。选项A不正确，因为它删除了整个模板，而不仅仅是最新版本。选项B不正确，因为它将以前的版本重命名为当前版本，并且不删除任何内容。选项C不正确，因为它会检出最新版本并将其从文件夹中删除，而不是从库中删除。

解析：解析:You can use the vCenter Server appliance GUI installer to restore a vCenter Server to an ESXi host or a vCenter Server instance. The restore procedure has two stages. The first stage deploys a new vCenter Server appliance. The second stage populates the newly deployed vCenter Server appliance with the data stored in the file-based backup.您可以使用vCenter Server appliance GUI安装程序将vCenter Server恢复到ESXi主机或vCenter Server实例。还原过程有两个阶段。第一阶段部署新的vCenter Server设备。第二阶段用基于文件的备份中存储的数据填充新部署的vCenter Server应用装置。

解析：解析: Complicated， the question does not comment on whether the path is redundant， if not redundant the correct answer would be D， but if we take into account good practices， the FC would be redundant. 这个问题很复杂，没有评论路径是否冗余，如果不冗余，正确答案应该是D，但是如果我们考虑好的实践，FC将是冗余的。Book course: 6-23 Fibre Channel SAN Components Using SAN switches， you can set up path redundancy to address any path failures from host server to switch， or from storage array to switch. 6-25 Multipathing with Fibre Channel By default， ESXi hosts use only one path from a host to a given LUN at any one time. If the path actively being used by the ESXi host fails， the server selects another available path.书籍课程:6-23光纤通道SAN组件使用SAN交换机，您可以设置路径冗余来解决从主机服务器到交换机或从存储阵列到交换机的任何路径故障。6-25光纤通道多路径默认情况下，ESXi主机在任何时候都只使用一条从主机到给定LUN的路径。如果ESXi主机当前使用的路径出现故障，服务器会选择另一条可用路径。

解析：解析:vSphere vMotion allows for the non-disruptive migration of a virtual machine between two clusters in a single vCenter instance， as long as there is shared storage and network connectivity between the clusters.vMotion is used to move the VM to a different cluster within the same vCenter. This only works if both clusters share the same storage. If they don＇t you also need to perform a Storage vMotion. Cross vCenter Migration is only used to migrate to a different vCenter.只要群集之间存在共享存储和网络连接，vSphere vMotion就可以在单个vCenter实例中的两个群集之间无中断地迁移虚拟机。vMotion用于将虚拟机移动到同一vCenter内的不同群集。这只有在两个群集共享相同存储时才有效。如果没有，您还需要执行Storage vMotion。跨vCenter迁移仅用于迁移到不同的vCenter。

解析：解析:Three features that are only available when using vSphere Distributed Switches instead of vSphere Standard Switches are port mirroring， which allows monitoring network traffic on a virtual switch port; Netflow， which allows collecting IP traffic information from a virtual switch; and configuration backup and restore， which allows saving and restoring distributed switch settings.只有在使用vSphere分布式交换机而不是vSphere标准交换机时才可用的三项功能是端口镜像，它允许监控虚拟交换机端口上的网络流量;Netflow，允许从虚拟交换机收集IP流量信息;以及配置备份和恢复，允许保存和恢复分布式交换机设置。
