What are two examples of design considerations when working with VXLAN? (Choose two.)
The correct answer is A. A multicast enabled underlay helps to handle broadcast, unknown unicast, and multicast traffic in B. A VXLAN tunnel end-point can be terminated on hardware or software. VXLAN uses multicast in the underlay to handle BUM (Broadcast, Unknown unicast, Multicast) traffic efficiently when a control plane like EVPN is not deployed. VXLAN Tunnel Endpoints (VTEPs) can be implemented in hardware (switches) or software (hypervisors, virtual switches)…

Options
- AA multicast enabled underlay helps to handle broadcast, unknown unicast, and multicast traffic in
- BA VXLAN tunnel end-point can be terminated on hardware or software.
- CVTEP is a 24-bit field in the VXLAN header used to uniquely identify the VXLAN.
- DEVPN control plane is a mandatory technology when you have VXLANs stretching Layer 2
- EVNI is a 48-bit field in the VLAN header used to uniquely identify the VXLAN.

Explanation
VXLAN uses multicast in the underlay to handle BUM (Broadcast, Unknown unicast, Multicast) traffic efficiently when a control plane like EVPN is not deployed. VXLAN Tunnel Endpoints (VTEPs) can be implemented in hardware (switches) or software (hypervisors, virtual switches), providing deployment flexibility.
