61、Exhibit switch An administrator configures a distributed switch and adds the first VMware ESXi server to it.The administrator also performs the following activities:•The administrator assigns two uplinks to the distributed switch.•The administrator enables uplink teaming.When attempting to perform a health check of the teaming policy， the health status of the Teaming and Failover reports as ＇ Unknown?， as seen in the exhibit.What can the administrator changes in the distributed switch for the health status to report correctly

解析：解析: The minimum supported network throughput in Gb/s for each host in an all flash vSAN cluster based on the vSAN Original Storage Architecture (OSA) is 10. vSAN Express Storage Architecture (ESA) are only supported with 25Gbps and higher connection speeds. ESA ReadyNodes configured for vSAN ESA will be configured with 25/50/100Gbps NICs. vSAN OSA all-flash configurations are only supported with a 10Gb or higher connections. One reason for this is that the improved performance with an all-flash configuration may consume more network bandwidth between the hosts to gain higher throughput.在基于vSAN原始存储体系结构(OSA)的全闪存vSAN群集中，每个主机支持的最低网络吞吐量(Gb/s)为10。vSAN Express Storage Architecture(ESA)仅支持25Gbps和更高的连接速度。为vSAN配置的ESA读取节点ESA将配置25/50/100Gbps网卡。vSAN OSA全闪存配置仅支持10Gb或更高的连接。其中一个原因是，全闪存配置提高的性能可能会消耗主机之间更多的网络带宽来获得更高的吞吐量。

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

解析：The administrator should take these three steps to perform an update to vSphere clusters that are running vSAN: Configure vSphere Lifecycle Manager with an image for the cluster, which allows the administrator to specify the desired ESXi version and firmware for the hosts in the cluster. Register the vendor hardware management system as a vCenter Server extension, which allows the administrator to update the firmware on the hosts using vSphere Lifecycle Manager. The vendor hardware management system can also provide the firmware updates to vSphere Lifecycle Manager, so there is no need to download them from the vendor website separately. Run a hardware compatibility check using vSphere Lifecycle Manager, which verifies that the new software and firmware versions are compatible with the vSAN Hardware Compatibility List.管理员应采取以下三个步骤来对运行vSAN的vSphere集群执行更新:使用集群映像配置vSphere Lifecycle Manager，这允许管理员为集群中的主机指定所需的ESXi版本和固件。将供应商硬件管理系统注册为vCenter Server扩展，这允许管理员使用vSphere Lifecycle Manager更新主机上的固件。供应商硬件管理系统还可以向vSphere Lifecycle Manager提供固件更新，因此无需单独从供应商网站下载。使用vSphere Lifecycle Manager运行硬件兼容性检查，验证新的软件和固件版本是否与vSAN硬件兼容性列表兼容。

解析：解析: Option B is correct because it allows the administrator to copy the storage settings from Standard-Config host profile to all other host profiles without affecting other settings. Option A is incorrect because it only exports host customizations and not host profile settings. Option C is incorrect because it creates a new host profile instead of modifying the existing ones. Option D is incorrect because it attaches the Standard-Config host profile to the other hosts instead of changing their host profiles.选项B是正确的，因为它允许管理员将存储设置从标准配置主机配置文件复制到所有其他主机配置文件，而不会影响其他设置。选项A不正确，因为它仅导出主机自定义设置，而不导出主机配置文件设置。选项C不正确，因为它创建了一个新的主机配置文件，而不是修改现有的配置文件。选项D不正确，因为它将标准配置主机配置文件附加到其他主机，而不是更改它们的主机配置文件。

解析：解析: Option B and D are correct because they allow the administrator to create a virtual machine customization specification， which can be used to customize guest operating system settings for multiple virtual machines， and convert the virtual machine to a template， which can be used to create full clones of server workloads.Option A is incorrect because assigning appropriate permissions on the virtual machine does not prepare it for deployment for multiple users. Option C is incorrect because upgrading the virtual hardware does not prepare it for deployment for multiple users. Option E is incorrect because taking a snapshot of the virtual machine does not prepare it for deployment for multiple users. References:解释选项B和D是正确的，因为它们允许管理员创建虚拟机自定义规范，该规范可用于为多个虚拟机自定义来宾操作系统设置，并将虚拟机转换为模板，该模板可用于创建服务器工作负载的完整克隆。选项A不正确，因为在虚拟机上分配适当的权限并不能为多用户部署做好准备。选项C不正确，因为升级虚拟硬件不会为多用户部署做好准备。选项E不正确，因为拍摄虚拟机的快照并不能为多用户部署做好准备。

解析：解析: The fatal error “Secure Boot Failed” may indicate that either the kernel or a package (VIB or driver) has been tampered with， which violates the Secure Boot integrity check.致命错误“安全引导失败”可能表示内核或软件包(VIB或驱动程序)已被篡改，这违反了安全引导完整性检查。

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: To successfully log into the vSphere Host Client using the FQDN for the ESXi host， the administrator needs to ensure a DNS A Record is created for the VMware ESXi host on the corporate DNS servers， which maps its FQDN to its IP address; and update the VMware ESXi Management Network DNS configuration to use the corporate DNS servers for name resolution， which allows resolving its FQDN.要使用ESXi主机的FQDN成功登录vSphere Host Client，管理员需要确保在企业DNS服务器上为VMware ESXi主机创建DNS A记录，该记录会将其FQDN映射到其IP地址;并更新VMware ESXi管理网络DNS配置，以使用企业DNS服务器进行名称解析，从而允许解析其FQDN。
