Which two statements about OTV are true?(Choose two)

The Authoritative Edge Device (AED) in OTV is elected per VLAN and is responsible for forwarding Broadcast, Unknown Unicast, and Multicast (BUM) traffic only for the VLANs it is authoritative for, not for all extended VLANs universally.

The OTV join interface must be a Layer 3 interface capable of IP routing, as it establishes the overlay connectivity over the underlying IP transport network.

OTV typically requires an Advanced Services license on Cisco Nexus 7000 Series switches for its functionality to be enabled and utilized.

OTV best practices and design principles often dictate using a separate Virtual Device Context (VDC) for configuring Switched Virtual Interfaces (SVIs) for extended VLANs to maintain clear separation and avoid potential conflicts with the transport network.

For a single OTV overlay instance, only one Layer 3 interface can be designated as the active join interface to establish adjacency with other edge devices over the transport network.

OTV is a Layer 2 VPN technology that encapsulates Layer 2 traffic over an IP-based underlay network and does not itself run over a distance vector routing protocol, although the underlay may use one.
