You are evaluating which method to use for learning MAC addresses in your VXLAN network.

Which statement is true in this scenario?
A . Multicast exchanges MAC addresses through data plane learning and is more reliable than EVPN.
B . EVPN exchanges MAC addresses through control plane learning and is more reliable than multicast.
C . EVPN exchanges MAC addresses through data plane learning and is more reliable than multicast.
D . Multicast exchanges MAC addresses through control plane learning and is not more reliable than EVPN.

Answer: B

Explanation:

Ethernet VPN (EVPN) provides control plane-based MAC address learning. This means that MAC addresses are exchanged and learned via BGP messages rather than through traditional data plane flooding. This approach is more scalable and reliable compared to multicast-based MAC address learning, where MAC addresses are learned through data plane flooding. Control plane learning with EVPN is less prone to issues like broadcast storms and provides a more efficient and stable mechanism for MAC address dissemination in large-scale networks.
