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)…

Question

What are two examples of design considerations when working with VXLAN? (Choose two.)

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.
