Refer to the exhibit.
VLAN 1 and VLAN 2 are configured on the trunked links between Switch
A and Switch B. Port Fa 0/2 on Switch B is currently in a blocking state for both VLANs.
What should be done to load balance VLAN traffic between Switch A and Switch B?
A.
Lower the port priority for VLAN 1 on port 0/1 for Switch A.
B.
Lower the port priority for VLAN 1 on port 0/2 for Switch A.
C.
Make the bridge ID of Switch B lower than the ID of Switch A.
D.
Enable HSRP on the access ports.
Explanation:
Load Sharing Using STP Port Priorities
When two ports on the same switch form a loop, the STP port priority setting determines
which port is enabled and which port is in a blocking state. The priorities on a parallel trunk
port can be set so that the port carries all the traffic for a given VLAN. The trunk port with the
higher priority (lower values) for a VLAN is forwarding traffic for that VLAN. The trunk port
with the lower priority (higher values) for the same VLAN remains in a Blocking state for that
VLAN. One trunk port sends or receives all traffic for the VLAN.
Traffic goes over upper link. To make vlan 1 traffic go to lower link you have to increase its priority ( by lowering numeric value ). so correct answer is A , or you need to change answers to “lower the port priority value for vlan 1 .. “
