B.The Spanning Tree Protocol (STP) is an evolution of the IEEE 802.1w standard.
C.Per-VLAN Spanning Tree (PVST) supports 802.1Q trunking.
D.Per-VLAN Spanning Tree Plus(PVST+) is an enhancement to 802.1Q specification and is supported only on Cisco devices.
E.Rapid Spanning Tree Protocol (RSTP) includes features equivalent to Cisco PortFast, UplinkFast, and BackboneFast for faster network reconvergence.
F.Multiple Spanning Tree (MST) assumes one spanning-tree instance for the entire Layer 2 network, regardless of the multiple number of VLANs
