Refer to Exhibit. With Access-1, what needs to be identically configured With MSTP to load- balance VLANS?
The correct answer is B. Spanning-tree instance vlan mapppjng. To load-balance VLANs with MSTP, you need to configure the same VLAN-to-instance mapping on all switches in the same MST region. This means that you need to assign different VLANs to different MST instances, and then adjust the spanning tree parameters (such as priority, cost…

Explanation
To load-balance VLANs with MSTP, you need to configure the same VLAN-to-instance mapping on all switches in the same MST region. This means that you need to assign different VLANs to different MST instances, and then adjust the spanning tree parameters (such as priority, cost, or port role) for each instance to achieve the desired load balancing. For example, you can make one switch the root for instance 1 and another switch the root for instance 2, and then map half of the VLANs to instance 1 and the other half to instance 2.
