A、 Ensure that each vCenter Server Appliance is configured to use a Network Time Protocol (NTP) source.
B、 Ensure that each ESXi host is configured to use a Precision Time Protocol (PTP) source.
C、 Ensure that each ESXi host is configured to use a Network Time Protocol (NTP) source.
D、 Ensure that each vCenter Server Appliance is configured to use a Precision Time Protocol (PTP) source.
答案：B
解析：解析: To comply with the policy of synchronizing time with an external source that is accurate to the microsecond， the administrator needs to ensure that each ESXi host is configured to use a PTP source， which provides higher accuracy than NTP.为了遵守与精确到微秒的外部源同步时间的策略，管理员需要确保每台ESXi主机都配置为使用PTP源，这比NTP提供了更高的精确度。

解析：解析: Option A and D are correct because they allow vSphere Lifecycle Manager to automatically control maintenance mode on the ESXi hosts and remediate them in parallel or in sequence. Option B and C are incorrect because they require manual intervention to place the hosts into maintenance mode or to stage the software on each host， which is not efficient or minimal downtime.选项A和D是正确的，因为它们允许vSphere Lifecycle Manager自动控制ESXi主机上的维护模式，并并行或按顺序修复它们。选项B和C是不正确的，因为它们需要手动干预来将主机置于维护模式或在每台主机上存放软件，这是低效的或最少的停机时间。
A. Attach the host profile to the new host
B. Duplicate the host profile
C. Copy the host settings from the new host
D. Import the host profile
解析：解析: The task that should be completed prior to checking the compliance with an existing host profile is to attach the host profile to the new host， which allows applying the configuration template of the reference host to the new host.在检查与现有主机配置文件的符合性之前，应该完成的任务是将主机配置文件附加到新主机，这允许将参考主机的配置模板应用到新主机。

解析：解析: The administrator should clone Linux-01， which creates a copy of the virtual machine template. The administrator should then convert the clone to a VM， which allows the administrator to power on and modify the virtual machine. The administrator should then install the software patch on the VM， which updates the application. The administrator should then convert the VM back to a template， which preserves the changes made to the VM and allows users to deploy VMs from it.管理员应该克隆Linux-01，这将创建虚拟机模板的副本。然后，管理员应将克隆转换为虚拟机，这允许管理员启动并修改虚拟机。然后，管理员应该在虚拟机上安装软件补丁，从而更新应用程序。然后，管理员应该将虚拟机转换回模板，这样可以保留对虚拟机所做的更改，并允许用户从中部署虚拟机。
A. The virtual machine will be restored to the parent snapshot in a powered on state
B. The virtual machine will be restored to the parent snapshot in a powered off state.
C. The virtual machine will be restored to the child snapshot in a powered off state
D. The virtual machine will be restored to the child snapshot in a powered on state
解析：解析:Powered on (does not include memory) Reverts to the parent snapshot and the virtual machine is powered off. Powered off (does not include memory) Reverts to the parent snapshot and the virtual machine is powered off.启动(不包括内存)恢复到父快照，虚拟机关闭。关闭(不包括内存)恢复到父快照，虚拟机关闭。

解析：解析: An administrator is tasked with applying updates to a vSphere cluster running vSAN using vSphere Lifecycle Manager. Downtime to the ESXI hosts must be minimal while the work Is completed. I he administrator has already completed the following steps and no errors have been returned:管理员的任务是使用vSphere Lifecycle Manager向运行vSAN的vSphere集群应用更新。工作完成时，ESXI主机的停机时间必须尽可能短。如果管理员已经完成了以下步骤，并且没有返回任何错误:• Downloaded all applicable software and created a new Image .• Attached the new Image to the cluster and run a compliance check against the Image for the cluster .• Ran a remediation pre-check for the cluster.下载了所有适用的软件并创建了新的映像.将新映像连接到集群，并针对集群的映像运行合规性检查.为集群运行补救预检查.

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。
A. Host Connection Lost
B. Lost Network Path Redundancy
C. Lost Network Connectivity
D. Lost Storage Connectivity
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。
