Hi,
The answer is D.
The inter-VLAN ARP proxy function CAN be enabled on the VLANIF interface of the super VLAN to implement communication between sub-VLANs.
Please refer to the Example for Configuring Inter-VLAN Proxy ARP.

O D. The inter-VLAN ARP proxy function can't be enabled on the VLANIF interface of the super VLAN to implement communication between sub-VLANs.


ARP is applicable only to devices on the same physical network. When a device on a physical network needs to send IP datagrams to another physical network, the gateway is used to query the routing table to implement communication between the two networks. However, routing table query consumes system resources and can affect other services. To resolve this problem, deploy proxy ARP on an intermediate device. Proxy ARP enables devices that reside on different physical network segments but on the same IP network to resolve IP addresses to MAC addresses. This feature helps reduce system resource consumption caused by routing table queries and improves the efficiency of system processing.
