A. Apply Global permissions to assign the Read Only role to the root vCenter object.Apply vCenter permissions to assign the custom role to the workload vSphere clusters and enable propagation
B. Apply Global permissions to assign the Read Only role to the root vCenter object and enable propagation. Apply vCenter permissions to assign the custom role to the workload vSphere clusters and enable propagation
C. Apply Global permissions to assign the Read Only role to the root vCenter object. Apply vCenter permissions to assign the custom role to the workload vSphere clusters.
D. Apply Global permissions to assign the Read Only role to the root vCenter object and enable propagation. Apply vCenter permissions to assign the custom role to the workload vSphere clusters.
解析：解析: Option D is correct because it allows the administrator to apply Global permissions to assign the Read Only role to the root vCenter object and enable propagation， which will apply to all of the inventory objects in vCenter， and then apply vCenter permissions to assign the custom role to the workload vSphere clusters， which will override the Global permissions and allow users to edit all of the inventory objects associated with the workload vSphere clusters. Option A is incorrect because it will not enable propagation for the Global permissions， which will limit the Read Only role to the root vCenter object only. Option B is incorrect because it will enable propagation for both the Global and vCenter permissions， which will create a conflict between the Read Only and custom roles. Option C is incorrect because it will not enable propagation for either the Global or vCenter permissions， which will limit the Read Only role to the root vCenter object only and the custom role to the workload vSphere clusters only.选项D是正确的，因为它允许管理员应用全局权限将只读角色分配给根vCenter对象并启用传播，这将应用于vCenter中的所有清单对象，然后应用vCenter权限将自定义角色分配给工作负载vSphere群集，这将覆盖全局权限并允许用户编辑与工作负载vSphere群集关联的所有清单对象。选项A不正确，因为它不会启用全局权限的传播，从而将只读角色仅限于根vCenter对象。选项B不正确，因为它将启用全局和vCenter权限的传播，这将在只读和自定义角色之间产生冲突。选项C是不正确的，因为它不会为全局或vCenter权限启用传播，这会将只读角色仅限于根vCenter对象，将自定义角色仅限于工作负载vSphere群集。
A. Create a new published content library In each secondary site
B. Configure the New York subscribed content library to download content immediately.
C. Configure the Tokyo subscribed content library to download content immediately
D. Configure the Tokyo subscribed content library to download content when needed
E. Create a new published content library at the primary site
F. Configure the New York subscribed content library to download content when needed.
G. Create a new subscribed content library in each secondary site
H.
I.
J.
解析：解析: The administrator should take these four steps to configure the content library solution before adding a VM template: Create a new published content library at the primary site， which allows the administrator to share the VM template with other sites.Configure the New York subscribed content library to download content immediately， which ensures that the new VM template is downloaded from the primary site as soon as possible. Configure the Tokyo subscribed content library to download content when needed， which saves disk space at the secondary site by downloading only the metadata of the VM template until it is deployed. Create a new subscribed content library in each secondary site， which allows the administrator to subscribe to the published content library at the primary site and synchronize the VM template.在添加VM模板之前，管理员应该采取以下四个步骤来配置内容库解决方案:在主站点创建新的已发布内容库，这允许管理员与其他站点共享VM模板。将纽约订阅的内容库配置为立即下载内容，这可确保尽快从主站点下载新的虚拟机模板。将Tokyo subscribed content library配置为在需要时下载内容，这通过在部署之前仅下载虚拟机模板的元数据来节省辅助站点的磁盘空间。在每个辅助站点中创建一个新的订阅内容库，这允许管理员订阅主站点上发布的内容库，并同步虚拟机模板。
A. On the vCenter Management Interface
B. On the ESXi host using the Direct Console User Interface
C. On the vCenter Server Appliance
D. In the vSphere Client when viewing the vCenter virtual machine
解析：解析: The administrator can find log files containing information related to user login activities on the vCenter Server Appliance， which is a preconfigured Linux-based virtual machine that runs all vCenter Server services. The log files are located in /var/log/vmware/vmware-vpx/vpxd.log and /var/log/vmware/sso/ssoAdminServer.log directories.管理员可以在vCenter Server Appliance上找到包含用户登录活动相关信息的日志文件，vCenter Server Appliance是一个预配置的基于Linux的虚拟机，运行所有vCenter Server服务。日志文件位于/var/log/VMware/VMware-vpx/vpxd . log和/var/log/VMware/SSO/ssoadminserver . log目录中
A. Network latency must be less than 10 milliseconds
B. They must have a supported Wide Area Network (WAN).

解析：解析:When configuring vCenter High Availability (HA)， two of the requirements for the active， passive， and witness nodes are that network latency must be less than 10 milliseconds， which ensures reliable communication between them; and they must have a minimum of a 1 Gbps network adapter， which provides sufficient bandwidth for data replication.在配置vCenter高可用性(HA)时，对主动、被动和见证节点的两个要求是网络延迟必须小于10毫秒，这可确保它们之间的可靠通信;他们必须至少有一个1 Gbps的网络适配器，为数据复制提供足够的带宽。

解析：
A. Encrypted vSphere vMotion
B. Unified Extensible Firmware Interface (UEFI) Secure Boot
C. Host Encryption
D. VM Encryption
解析：解析: The feature that should be configured to provide encryption for workloads within an existing vSphere cluster without requiring any specific hardware is VM Encryption， which allows encrypting VMs at rest and during vMotion.在不需要任何特定硬件的情况下，为现有vSphere群集中的工作负载提供加密应该配置的功能是虚拟机加密，它允许在静态和vMotion期间加密虚拟机。
A. vCenter Identity Provider Federation with Active Directory Federation Services as the identity provider
B. vCenter Single Sign-On with Active Directory over LDAP as the identity source

解析：解析: „ In vCenter Server Identity Provider Federation， vCenter Server uses the OpenID Connect (OIDC) protocol to receive an identity token that authenticates the user with vCenter Server.“ Integrated Windows Authentication is deprecated since vSphere 7.0在vCenter Server身份提供商联盟中，vCenter Server使用OpenID连接(OIDC)协议接收身份令牌，该令牌通过vCenter Server对用户进行身份验证。“从vSphere 7.0开始，集成Windows身份验证已被弃用

B. Inflate the disk files for each VM.
C. Delete all snapshots for each VM.
D. Storage vMotion each VM to another datastore.

解析：解析: Consolidating snapshots for each VM will merge any snapshot files that are not associated with a snapshot in Snapshot Manager into the base disk file and free up datastore space.整合每个虚拟机的快照会将快照管理器中与快照无关的所有快照文件合并到基本磁盘文件中，并释放数据存储空间。The presence of redundant delta disks can adversely affect the virtual machine performance. You can combine such disks without violating a data dependency. After consolidation， redundant disks are removed， which improves the virtual machine performance and saves storage space.冗余增量磁盘的存在会对虚拟机性能产生负面影响。您可以在不违反数据依赖性的情况下组合这些磁盘。整合后，冗余磁盘将被移除，从而提高虚拟机性能并节省存储空间。
