Which technology relies on STP as a failsafe mechanism?
Answer : D
Explanation:
vPC technology allows to build a loop free topology by levering port-channel from access device to vPC domain. A port-channel is seen as a logical link from STP standpoint so vPC domain with vPC-attached access device globally form a star topology at L2 (there is no STP blocked ports in this type of topology). For that case, STP is used as a fail-safe mechanism to protect any network loop caused by human error (like plugging a loopback cable across the 2 vPC peer device).
