How does NSX simplify the underlying physical network?
A.
All configuration and state information is available via the REST APIs to automate the
configuration of the physical network.
B.
All configuration and state information are readily accessible, as is the mapping between virtual
network topologies and the physical network.
C.
All configuration and state information is stored in the local NSX BPDU database, eliminating
the need for Spanning Tree Protocol (STP) on the physical network.
D.
All configuration and state information is cached by the NSX controllers, reducing the number of
MAC/ARP table entries on the physical network.
the control plane communication between the ESXi hosts and the controller cluster to populate the VTEP, MAC and ARP tables on the controller nodes.
VM populates its ARP cache, it will be able to send data traffic to other VMs,

Another weird question with non-relevant choices. B is most sane choice but its not relevant to the question.

Option D, the physical network does not have to process/forward more ARP traffic because it´s locally managed by NSX Controller cluster in every ESXi host.

B is more relevant as the q says which one simplifies network,D is a feature of having controllers and specifically uni-cast and hybrid replication,which I thing does not simplify something,it does reduce ARP broadcasts
