答案：B
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:: ESXi 7 and later supports RoCE v2 technology， which enables RDMA over an Ethernet network. Hosts use an RDMA network adapter installed on the host and a software NVMe over RDMA storage adapter.解释:ESXi 7及更高版本支持RoCE v2技术，该技术可通过以太网实现RDMA。主机使用安装在主机上的RDMA网络适配器和RDMA软件NVMe存储适配器。
A. Add a minimum of three hosts with two uplinks each
B. Add a minimum of two hosts with two uplinks each
C. Add a minimum of three hosts with four uplinks ea/ch
D. Add a minimum of two hosts with one uplink each
A. VMware Aria Operations for Logs
B. VMware Skyline Advisor Pro
C. VMware Skyline Health
D. VMware Aria Operations
解析：解析: The solution that should be recommended to reduce the risk of outages by proactively identifying and resolving issues with the environment and reducing the complexity of uploading log bundles is VMware Skyline Health， which provides automated support and proactive recommendations for vSphere.应推荐的解决方案是VMware Skyline Health，它通过主动识别和解决环境问题以及降低上传日志捆绑包的复杂性来降低停机风险，为vSphere提供自动化支持和主动建议。
A. External Switch Tagging (EST)
B. None
C. Virtual Guest Tagging (VGT)
D. Virtual Switch Tagging (VST)
E.
F.
G.
H.
I.
J.
解析：解析:The tagging mode that is required is Virtual Guest Tagging (VGT)， which allows VLAN tagging to be done at the VM level. VGT requires that the VLAN ID on the switch port group be set to 4095， which is a special value that indicates that packets from all VLANs are allowed to pass through. References:所需的标记模式是虚拟来宾标记(VGT)，它允许在虚拟机级别完成VLAN标记。VGT要求交换机端口组上的VLAN ID设置为4095，这是一个特殊值，表示允许来自所有VLAN的数据包通过。
A. Direct Console User Interface (DCUI)
B. vCenter Management Interface (VAMI)
C. vSphere Client
D. vCenter GUI Installer
解析：解析:You can use the vCenter Server appliance GUI installer to restore a vCenter Server to an ESXi host or a vCenter Server instance. The restore procedure has two stages. The first stage deploys a new vCenter Server appliance. The second stage populates the newly deployed vCenter Server appliance with the data stored in the file-based backup.您可以使用vCenter Server appliance GUI安装程序将vCenter Server恢复到ESXi主机或vCenter Server实例。还原过程有两个阶段。第一阶段部署新的vCenter Server设备。第二阶段用基于文件的备份中存储的数据填充新部署的vCenter Server应用装置。
A. Administrator
B. Can View
C. Owner
D. Can Edit
解析：解析: The Can Edit role would provide the minimum required permissions to delete Tanzu Kubernetes Grid (TKG) cluster objects in a vSphere Namespace， as it allows creating， updating， and deleting objects within a namespace.“可以编辑”角色将提供在vSphere命名空间中删除Tanzu Kubernetes Grid (TKG)集群对象所需的最低权限，因为它允许在命名空间中创建和删除对象。
A. 1. Use the Remediate option In vSphore Lifecycle Manager to remediate all of the ESXI hosts in the cluster In parallel. 2. Allow vSphere Lifecycle Manager to automatically control maintenance mode on the ESXI hosts.
B. 1. Place each of the ESXI hosts into maintenance mode manually. 2. Use the Stage option In vSphere Lifecycle Manager to stage the required software on all ESXi hosts one at a time.
C. 1. Leave all ESXI hosts In the cluster operational. 2. Use the Stage All option In vSphere Lifecycle Manager to stage the required software onto all ESXI hosts one at a time.
D. 1. Leave all ESXI hosts In the cluster operational 2. Use the Stage All option In vSphere Lifecycle Manager to stage the required software onto all ESXI hosts In the cluster In parallel.
E. 1.Use the Remediate Option In vSphere Lifecycle Manager to remediate all of the ESXI hosts In the cluster In sequence. 2. Allow vSphere Lifecycle Manager to automatically control maintenance mode on the ESXI hoy
F.
G.
H.
I.
J.
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。
