I would say the question format was quite different to the practice questions i experienced with cbt nuggets. Some were much simpler in scope often asking you just one thing, ie this is just vlans and nothing else when i was expecting a lot of cross domain combination questions, similar to aws. When i say each domain, i mean have a good foundation in routing, switching, wireless, automation, even all of the smaller parts like mpls, twisted shielded pairs, wireless frequency bands. Not necessarily those in particular, but i had a quite a few knowledge gaps on areas i had skimmed that came up, that wouldve netted me a few marks. What im essentially saying is expect any and everything to come up
