A vNetwork Distributed Switch is best described as?

A.
A distributed set of vNetwork Standard Switches on individual ESX Hosts capable of
forwarding traffic between hosts

B.
A distributed set of vNetwork Standard Switches that allow a virtual machine to
maintain a consistent network configuration between multiple ESX Hosts

C.
A single virtual switch that aggregates existing vNetwork Standard Switches

D.
A single virtual switch shared between multiple ESX Hosts

Explanation:
A VMware vNetwork Distributed Switch simplifies virtual machine networking by
enabling you to set up virtual machine networking for your entire datacenter from a
centralized interface. A single Network Distributed Switch spans many ESX hosts and
aggregates networking to a centralized datacenter level. vNetwork Distributed Switch
abstracts configuration of individual virtual switches and enables centralized
provisioning, administration and monitoring through VMware vCenter Server.
