What does 'active-active forwarding' mean in the context of EVPN-VXLAN?

Only one link is active at a time, with the other as a standby

All links in an Ethernet segment can forward traffic simultaneously

Traffic is forwarded only during business hours

The control plane is active while the data plane is passive

In an EVPN-VXLAN data center architecture, what is the primary role of Ethernet VPN (EVPN)?

To serve as the control plane that distributes MAC and IP reachability information for VXLAN overlays

To provide a dedicated physical connection between each pair of leaf switches

To provide the data-plane encapsulation that carries Ethernet frames over the IP fabric

To replace the need for any routing protocol in the underlay network

A network architect is designing an EVPN-VXLAN fabric and must decide between using EVPN for MAC learning or traditional data-plane learning. The architect is concerned about the impact of unknown unicast flooding on network performance. Which statement correctly describes how EVPN addresses this concern?

EVPN eliminates unknown unicast flooding by learning all MACs via BGP.

EVPN increases unknown unicast flooding due to BGP overhead.

EVPN reduces unknown unicast flooding by using multicast groups.

EVPN does not affect unknown unicast flooding.

A company is deploying EVPN-VXLAN in its data center to support active-active forwarding for a pair of access switches. The design must ensure that both switches can forward traffic for the same VLAN without loops. Which EVPN feature enables this?
