Refer to the exhibit.
The output that is shown is generated at a switch. Which three of these statements are true? (Choose three.)
A. All ports will be in a state of discarding, learning, or forwarding.
B. Thirty VLANs have been configured on this switch.
C. The bridge priority is lower than the default value for spanning tree.
D. All interfaces that are shown are on shared media.
E. All designated ports are in a forwarding state.
F. This switch must be the root bridge for all VLANs on this switch.
This answer is incorrect. The correct answer is ACE and the explanation appears best here: http://vceguide.com/which-three-statements-are-true-7/
We are looking at vlan output for 30 only and can’t tell if this is the root bridge for any other vlans, so F cannot be correct.
