Which of the following statements regarding G.8032 Ethernet Ring Protection is FALSE?

  • A Uses standard Ethernet dot1q and QinQ encapsulation.
  • B Requires R-STP as the protocol to carry control information.
  • C Ethernet Ring APS is a defined ITU standard.
  • D Standard Ethernet forwarding, learning and flooding rules apply.
Explanation

ITU-T G.8032 defines the Ring Automatic Protection Switching (R-APS) protocol to coordinate Ethernet-ring protection switching. RSTP is therefore not required to carry G.8032 control information. G.8032/Y.1344 is the ITU-T standard that defines Ethernet ring protection switching and the R-APS protocol.
