Which two statements are correct about the campus fabric core-distribution architecture? (Choose two.)

The correct answer is A. Only the core and distribution tiers are part of the EVPN-VXLAN topology. D. The access tier does not participate in the EVPN-VXLAN topology. In a core-distribution campus fabric model, the EVPN-VXLAN overlay is established only between the core and distribution tiers. The access switches are not part of the EVPN fabric; they connect upstream to distribution but do not run VXLAN tunnels. "In the core-distribution…

Explanation

In a core-distribution campus fabric model, the EVPN-VXLAN overlay is established only between the core and distribution tiers. The access switches are not part of the EVPN fabric; they connect upstream to distribution but do not run VXLAN tunnels. "In the core-distribution campus fabric, only the core and distribution layers participate in the EVPN-VXLAN topology. The access layer connects to the distribution switches and forwards traffic but does not take part in the EVPN- Option A: Correct -- EVPN-VXLAN is built between core and distribution tiers. Option B: Incorrect -- both core and distribution participate, not just core. Option C: Incorrect -- access switches are excluded from EVPN-VXLAN participation. Option D: Correct -- the access layer does not participate in EVPN-VXLAN.
