LAST WEEK'S ANSWER:
Answer: a
Topic Domain: 2b
Issue:
Given the show spanning-tree command output, how can you determine what
version of STP is in use?
Solution:
The show spanning-tree output might look like Rapid Spanning Tree is in
use. This is because port states reported reflect 802.1w options.
Notice, however, that the spanning tree version reported is IEEE. This
is the indication for 802.1d.
More Information:
show spanning-tree
