Which of the following specifications 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.
