Query: Guaranteed to FAIL the exam if you use this....

This isn't much of a review, but my ccnp friend has taken the Cisco MPLS exam OVER 6 times so far and failed every time. (I keep telling him to get some other books. Duh!)...maybe Cisco booby-trapped their exam so readers of THIS book will never get to 85% to pass ;-)
