Change my answer to LISP as it is for both Layer 2 and 3 - also, Fabricpath is conversational learning but that seems to be a benefit over TRILL https://netcraftsmen.com/designing-fabricpath/ https://community.cisco.com/t5/networking-knowledge-base/lisp-vxlan-fabric-solution-design-guide/ta-p/4934407

Answer is 'A' - Cisco enhanced TRILL (Transparent Interconnection of Lots of Links) to introduce FabricPath in the networking world. Both FabricPath and Trill are conversational learning.

I agree the answer is A. From the link, it considers the usage of FabricPath and Trill is the same although there are differents (P37). https://www.cisco.com/c/dam/global/en_ca/assets/plus/assets/pdf/FabricPath-RFULLER.pdf

TRILL is a layer 2 protocol that enables multipathing and load balancing in the network by allowing multiple parallel paths between switches. This means that traffic can be distributed across all available uplinks, which would increase performance and availability.

But you can't really configure TRILL on any Cisco Nexus, it's FabricPath which is little different then TRILL

TRILL is non conversational whereas LISP is. Since it is a redesign LISP sounds good
