C. Configure a Layer 3 LAG with the vlan-tagging option with the required logical units and the parameters needed to support the desired VLANs.
D. Configure a Layer 2 LAG with the vlan-tagging and inet options along with the required logical units and parameters needed to support the desired VLANs.

Host A is connected to Node1 on VLAN10. Host B is connected to Node2 on VLAN20. VLAN interfaces for both VLANs are configured on a QFabric system. Host A wants to connect to Host B but the QFabric system is missing the ARP entry of Host B. Which statement is true?
A. Node1 will generate the ARP request for Host B and flood it in VLAN20.
B. The network Node group will generate the ARP request for Host B in VLAN20.
