Security Fundamentals

Which protocol is employed in Software Defined Access (SDA) to create a tunnel between two edge nodes in different fabrics?

  • A Generic Router Encapsulation (GRE)
  • B Virtual Local Area Network (VLAN)
  • C Virtual Extensible LAN (VXLAN)
  • D Point-to-Point Protocol (PPP)
Explanation

Cisco Software-Defined Access uses VXLAN as the fabric data-plane encapsulation to build the overlay tunnel that carries traffic between fabric edge nodes. GRE is not the SDA fabric encapsulation, VLAN is a Layer 2 segmentation method rather than a tunnel protocol for SDA fabric transport, and PPP is a point-to-point link protocol unrelated to SDA overlay tunneling.
