A. vSphere Distributed Resource Scheduler (DRS)
B. vSphere vMotion
C. vSphere Faull Tolerance
D. vCLS Retreat Mode
E.
F.
G.
H.

J.
解析：解析: The feature that can be used to avoid the use of Storage vMotion on the vCLS VMs when performing maintenance on a datastore is vCLS Retreat Mode， which allows temporarily removing the vCLS VMs from the cluster without affecting the cluster services.在数据存储上执行维护时，可用于避免在vCLS虚拟机上使用Storage vMotion的功能是vCLS撤退模式，该模式允许临时从群集中删除vCLS虚拟机，而不会影响群集服务
A. In the ESXi host system config
B. In the alarm rule definitions
C. In the vCenter settings in the vSphere Client
D. in the vCenter Management Interface
E.
F.
G.
H.
I.
J.
解析：解析: Option C is correct because it allows the administrator to configure the mail server settings in the vCenter settings in the vSphere Client， which are required for sending email notifications for alarms. Option A is incorrect because it configures the mail server settings on an ESXi host system， which are not used for sending email notifications for alarms. Option B is incorrect because it configures the alarm rule definitions， which arealready enabled in the exhibit. Option D is incorrect because it configures the vCenter Management Interface， which is not used for sending email notifications for alarms. References:解释选项C是正确的，因为它允许管理员在vSphere Client的vCenter设置中配置邮件服务器设置，这是发送警报电子邮件通知所必需的。选项A不正确，因为它在ESXi主机系统上配置邮件服务器设置，这些设置不用于发送警报的电子邮件通知。选项B是不正确的，因为它配置了警报规则定义，这些定义在图中已经启用。选项D不正确，因为它配置vCenter管理界面，而该界面不用于发送警报电子邮件通知。
A. Ensure that the source and destination vCenter instances share the same Key Management Server (KMS).
B. Ensure that Encrypted vMotion Is turned off for the VM
C. Ensure that the VM is encrypted before attempting the migration
D. Ensure that the VM is powered off before attempting the migration.
E. Ensure that the source and destination vCenter Servers have a different Key Management Server (KMS).
F.
G.
H.
I.
J.
解析：解析: To ensure a successful migration of an encrypted VM to a secure environment， the administrator needs to ensure that the source and destination vCenter instances share the same Key Management Server (KMS)， which provides encryption keys for both environments; and ensure that the VM is encrypted before attempting the migration， which allows preserving its encryption status during vMotion.为了确保加密虚拟机成功迁移到安全环境，管理员需要确保源和目标vCenter实例共享同一个密钥管理服务器(KMS)，该服务器为两个环境提供加密密钥;并确保在尝试迁移之前对虚拟机进行加密，这样可以在vMotion过程中保留其加密状态。
A. Create a ＇Must run Virtual Machines to Hosts＇ anti-affinity rule.
B. Create a ＇Virtual Machines to Virtual Machines＇ anti-affinity rule.
C. Create a ＇Virtual Machines to Virtual Machines＇ dependency rule.
D. Create a ＇Should run Virtual Machines to Hosts＇ anti-affinity rule.

解析：
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。
A. vSphere vMotion
B. Cross vCenter Migration
C. vSphere Storage vMotion
D. vSphere Fault Tolerance
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。
A. Provide a live shadow Instance of a virtual machine (VM) that mirror， the primary VM to prevent data loss and downtime during outages
B. Implement Quality of Service (QoS) on network traffic within a vSphert Distributed Switch
C. Provide hardware accelerated data processing to boort infrastructure performance
D. Redistribute virtual machines across vSphere cluster host affinity rules following host failures or during maintenance operations
解析：解析: The role of vSphere Distributed Services Engine is to provide hardware accelerated data processing to boost infrastructure performance by offloading network services from the CPU to the DPU.VSP here Distributed Services Engine的作用是提供硬件加速数据处理，通过将网络服务从CPU转移到DPU来提升基础架构性能。
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。
An administrator set up the following configuration: • The distributed switch has three ESXi hosts， and each host has two 40 Gbps NICs.• The amount of bandwidth reserved for virtual machine （VM） traffic is 6 Gbps.The administrator wants to guarantee that VMs in the Finance distributed port group can access 50 percent of the available reserved bandwidth for VM traffic. k Given this scenario， what should the size (in Gbps) of the Finance network resource pool be?
A. 18
B. 80
C. 36
D. 120
E.
F.
G.
H.
I.
J.
解析：解析:The size of the Finance network resource pool should be 50 percent of the reserved bandwidth for VM traffic， which is 6 Gbps x 3 hosts = 18 Gbps.财务网络资源池的大小应为虚拟机流量预留带宽的50%，即6 Gbps x 3台主机= 18 Gbps。
A. Backup schedule
B. Certificates
C. Storage policies
D. Update policies
E. Permissions
F. Resource and Object limits

解析：解析: After creating a vSphere Namespace， three of the options that an administrator can configure are storage policies， which define how storage resources are allocated for objects within a namespace; permissions， which define who can access and manage objects within a namespace; and resource and object limits， which define how much CPU， memory， storage， and network resources can be consumed by objects within a namespace.创建vSphere命名空间后，管理员可以配置的三个选项是:存储策略，它定义如何为命名空间内的对象分配存储资源;权限，定义谁可以访问和管理名称空间内的对象;资源和对象限制，定义了名称空间中的对象可以消耗多少CPU、内存、存储和网络资源
