CCNP TSHOOT Exam Topology
Feb 21st
According to a post on Cisco Learning Network, Cisco will be releasing the topology used in the TSHOOT exam:
First, I am part of the exam development team. Second, what am about to reveal is not part of some secret NDA.
The new TSHOOT exam requires you to isolate issues on a defined network topology. The purpose of the exam is to evaluate troubleshooting skills, not how quickly you can grasp a network topology you have never seen. To this end, it is Cisco’s intent that the exam network topology be available for review before the candidate attempt the exam.
However, the wheels seem to move slowly and the network topologies have not been posted on CLN. Because of this I have authorized to make the topologies available through this discussion until they are officially posted.

This is the third question in a series of OEQs. The first and second questions were pretty popular, so I’ve decided to add more than one a week for a month or so. The answer to the second question has been added to the post.
Third question:
What are the port states of 802.1w?
