Which of the following specification will allow you to: associate VLAN groups to STP
instances so you can provide multiple forwarding paths for data traffic and enable load
balancing?

A.
IEEE 802.1d (STP)

B.
IEEE 802.1s (MST)

C.
IEEE 802.1Q (CST)

D.
IEEE 802.1w (RSTP)

Explanation:
IEEE 802.1s MST Overview
MST extends the IEEE 802.1w rapid spanning tree (RST) algorithm to multiple spanning
trees. This extension provides both rapid convergence and load balancing in a VLAN
environment. MST converges faster than PVST+. MST is backward compatible with 802.1D
STP, 802.1w (rapid spanning tree protocol [RSTP]), and the Cisco PVST+ architecture.
