So after reading through Wendell's book on STP, he says STP show commands, such as show spanning-tree vlan 10, will randomly output RSTP port roles, implying that RSTP 802.1w is being used, not STP 802.1d. According to attachment I included, two different switches from Wendell's book are both running Ieee (802.1d- STP)Per-vlan PVST. However, the bottom switch shows port roles that ONLY exist in 802.1w RSTP. As far as the Exam is concerned, Will shady, trick questions show up on the CCNA exam, where it shows you just the output of the bottom switch and asks what Version of STP is being used?
