   Which scenario is a primary advantage of using a distributed virtual switch over standard virtual switches?

   • AIt increases the number of virtual NICs per VM beyond the hypervisor limit.
   • BIt provides centralized management and consistent network policies across all hosts in a cluster.
   • CIt allows each host to have its own unique VLAN configuration.
   • DIt eliminates the need for physical network switches in the data center.

   A small enterprise runs a legacy line-of-business application on a physical Windows Server. The IT team wants to consolidate several such physical servers onto a single host to reduce hardware footprint and power consumption. They require near-native performance for the virtualized workloads and want to manage the virtualization layer independently of any desktop OS. Which approach meets these requirements?

   • AUse a type 2 hypervisor on a desktop workstation and migrate the legacy application to that workstation.
   • BInstall a type 2 hypervisor on Windows Server and run the legacy application in a VM on that host.
   • CRun the legacy application in a container on the physical server without any hypervisor.
   • DDeploy a type 1 hypervisor directly on the physical host and run the legacy application in a VM managed by that hypervisor.

   How does a type 1 hypervisor typically differ from a type 2 hypervisor in terms of performance?

   • AType 1 hypervisors are slower because they must emulate all hardware devices.
   • BType 1 hypervisors generally provide higher performance because they run directly on the hardware without a host OS.
   • CType 2 hypervisors generally provide higher performance because they leverage the host OS's optimized drivers.
   • DBoth types provide identical performance because they use the same virtualization techniques.

   A company has a vSphere environment with two clusters: one for production and one for development. The network team wants to apply different security policies to each cluster. They also want to ensure that VMs can migrate between hosts within a cluster without losing network configuration. Which virtual switch design should they use?

   • AUse a distributed virtual switch for each cluster, with separate distributed port groups for different security policies.
   • BUse a standard virtual switch for production and a distributed virtual switch for development.
   • CUse a standard virtual switch on each host, with identical configuration across all hosts.
   • DUse a single distributed virtual switch across both clusters, with different port groups for security policies.
