4、An administrator is tasked with configuring remote direct memory access (RDMA) over Converged Ethernet v2 (RoCE v2).Which two types of adapters must the administrator configure? (Choose two.)

解析：解析:Integrated Windows Authentication is now depreciated (from v7). ”The Active Directory over LDAP identity source is preferred over the Active Directory (Integrated Windows Authentication) option.”集成的Windows身份验证现在已经过时(从v7开始)。” LDAP身份源上的Active Directory优先于Active Directory(集成Windows身份验证)选项。

38、 Given the configuration shown in the exhibit， what should the administrator do if the latest VM template contains changes that are no longer needed?

解析：解析: Deleting App-LibTemplate (3) will remove the changes that are no longer needed and revert to the previous version of the template.删除App-LibTemplate (3)将删除不再需要的更改，并恢复到模板的前一版本。

解析：

解析：解析:VMWare: Small environment (up to 100 hosts or 1，000 virtual machines) Medium environment (up to 400 hosts or 4，000 virtual machine)The administrator should select the small deployment size for the new vCenter Server instance， which is suitable for an environment with up to 100 hosts or 1，000 virtual machines. The small deployment size has 4 vCPUs and 19 GB of memory， which can handle the current and expected growth of the environment. The other deployment sizes are either too large or too small for the environment.VMWare:小型环境(最多100台主机或1，000台虚拟机)中型环境(最多400台主机或4，000台虚拟机)管理员应为新的vCenter Server实例选择小型部署，这适用于最多100台主机或1，000台虚拟机的环境小型部署有4个vCPUs和19 GB内存，可以处理环境的当前和预期增长。其他部署规模对于环境来说要么太大，要么太小。

解析：解析: Option B， D and E are correct because they allow the administrator to replace the machine SSL certificates，the VMware Certificate Authority (VMCA) certificate and the solution user certificates with custom certificates generated from the Enterprise CA， which will ensure that all certificates are trusted by the Enterprise CA and minimize the ongoing management overhead of replacing certificates. Option A is incorrect because replacing the VMCA certificate with a self-signed certificate generated from the VMCA will not ensure that the certificate is trusted by the Enterprise CA. Option C is incorrect because replacing the machine SSL certificates with trusted certificates generated from the VMCA will not ensure that the certificates are trusted by the Enterprise CA. Option F is incorrect because replacing the solution user certificates with trusted certificates generated from the VMCA will not ensure that the certificates are trusted by the Enterprise CA. 选项B、D和E是正确的，因为它们允许管理员用企业CA生成的自定义证书替换机器SSL证书、VMware证书颁发机构(VMCA)证书和解决方案用户证书，这将确保企业CA信任所有证书，并将替换证书的持续管理开销降至最低。选项A不正确，因为用从VMCA生成的自签名证书替换VMCA证书不能确保该证书受到企业CA的信任。选项C是不正确的，因为用从VMCA生成的可信证书替换机器SSL证书不能确保证书被企业CA信任。选项F是不正确的，因为用从VMCA生成的可信证书替换解决方案用户证书不能确保证书被企业CA信任。

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。

解析：解析:Option A is correct because it allows the administrator to create a preferential rule between the DB group and PROD11 group， which will force the VMs in the DB group to run on the hosts in the PROD11 group if possible， but will allow them to run on the hosts in PROD55 group if necessary. Option B is incorrect because it will create a preferential rule between the DB group and PROD55 group， which will force the VMs in the DB group to run on the hosts in PROD55 group if possible， which is not what the administrator wants. Option C is incorrect because it is the same as option B. Option D is incorrect because it will create a required rule between the DB group and PROD11 group， which will force the VMs in the DB group to run only on the hosts in PROD11 group and not allow them to run on the hosts in PROD55 group if needed.选项A是正确的，因为它允许管理员在DB组和PROD11组之间创建一个优先规则，如果可能，该规则将强制DB组中的虚拟机在PROD11组中的主机上运行，但如果必要，将允许它们在PROD55组中的主机上运行。选项B是不正确的，因为它将在数据库组和PROD55组之间创建一个优先规则，如果可能的话，将强制数据库组中的虚拟机在PROD55组中的主机上运行，这不是管理员想要的。选项C不正确，因为它与选项b相同。选项D不正确，因为它将在数据库组和PROD11组之间创建一个必需的规则，该规则将强制数据库组中的虚拟机仅在PROD11组中的主机上运行，而不允许它们在需要时在PROD55组中的主机上运行。

解析：解析:Option B is correct because it allows the administrator to create a cold clone of the physical server using VMware vCenter Converter， which will create an image of the guest OS and application that can be moved to this remote data center without requiring network connectivity or affecting the application’s data. Option A is incorrect because creating a hot clone of the physical server using VMware vCenter Converter will require network connectivity and may affect the application’s data due to changes during conversion. Option C is incorrect because restoring the guest OS from a backup will require network connectivity and may not include the latest changes in the application. Option D is incorrect because using storage replication to replicate the guest OS and application will require network connectivity and may not be feasible for a physical server.选项B是正确的，因为它允许管理员使用VMware vCenter Converter创建物理服务器的冷克隆，这将创建来宾操作系统和应用程序的映像，这些映像可以移动到该远程数据中心，而不需要网络连接或影响应用程序的数据。选项A不正确，因为使用VMware vCenter Converter创建物理服务器的热克隆需要网络连接，并且可能会由于转换期间的更改而影响应用程序的数据。选项C不正确，因为从备份恢复来宾操作系统需要网络连接，并且可能不包括应用程序中的最新更改。选项D不正确，因为使用存储复制来复制来宾操作系统和应用程序需要网络连接，对于物理服务器来说可能不可行。

解析：解释为了满足这些要求，管理员应该采取的步骤是在现有集群上配置增强的vMotion兼容性(EVC)模式，并将两台新主机添加到集群中。EVC模式通过屏蔽不支持的处理器功能，允许虚拟机在不同代的CPU之间迁移。可以在现有集群上启用EVC模式，而不会影响已启动的虚拟机。

解析：解析: VCF includes the management domain and multiple workload domains. While VCF does use LCM to manage vCenter lifecycle， it is on-prem only (for now) and is not SaaS based. That only leave vSphere+. See the video in this link about upgrading remote vCenters managed by vSphere+.VCF包括管理域和多个工作负载域。虽然VCF确实使用LCM来管理vCenter生命周期，但它仅在本地部署(目前如此)，并且不在SaaS。只剩下vSphere+。请参见此链接中关于升级由vSphere+管理的远程vCenters的视频。
