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: 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。
An administrator set up the following configuration: • The distributed switch has four ESXi hosts， and each host has two 10 Gbps NICs. • In the Network I/O Control configuration， the amount of bandwidth reserved for virtual machine (VM) traffic if 4 Gbps. The administrator wants to guarantee that VMs in the Retail distributed port group can access 50 percent of the available reserved bandwidth for VM traffic. Given this scenario， what should the size (in Gbps ) of the Retail network resource pool be?

解析：解析: 4Gbps*8Nic=32Gbps*50%=16Gbps
A. Ensure that each vCenter Server Appliance is configured to use a Network Time Protocol (NTP) source.
B. Ensure that each ESXi host is configured to use a Precision Time Protocol (PTP) source.
C. Ensure that each ESXi host is configured to use a Network Time Protocol (NTP) source.
D. Ensure that each vCenter Server Appliance is configured to use a Precision Time Protocol (PTP) source.
解析：解析: To comply with the policy of synchronizing time with an external source that is accurate to the microsecond， the administrator needs to ensure that each ESXi host is configured to use a PTP source， which provides higher accuracy than NTP.为了遵守与精确到微秒的外部源同步时间的策略，管理员需要确保每台ESXi主机都配置为使用PTP源，这比NTP提供了更高的精确度。

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. Predictive DRS
B. vSphere HA Orchestrated Restart
C. vSphere HA Restart Priority
D. Proactive HA
解析：解析: An administrator is tasked with applying updates to a vSphere cluster running vSAN using vSphere Lifecycle Manager. Downtime to the ESXI hosts must be minimal while the work Is completed. I he administrator has already completed the following steps and no errors have been returned:管理员的任务是使用vSphere Lifecycle Manager向运行vSAN的vSphere集群应用更新。工作完成时，ESXI主机的停机时间必须尽可能短。如果管理员已经完成了以下步骤，并且没有返回任何错误:• Downloaded all applicable software and created a new Image .• Attached the new Image to the cluster and run a compliance check against the Image for the cluster .• Ran a remediation pre-check for the cluster.下载了所有适用的软件并创建了新的映像.将新映像连接到集群，并针对集群的映像运行合规性检查.为集群运行补救预检查.

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。
