There is an ARP storm in VDC 1. Some users on VDC 2notice that ARP is not resolving for their gatewayon
the Cisco Nexus core. What is the cause?
A.
The ARP CoPP class committed information rate is exceeded, resulting in ARP loss in all VDCs.
B.
The administrator has not correctly configured the ARP CoPP class in VDC 2.
C.
The ARP traffic in VDC 1 is copied to the host ports in VDC 2, causing overutilization and output discards
D.
Because the ARP process in the default VDC (VDC 1) is responsible for processing ARP traffic for all
VDCs, VDC 2 will be affected.
