"put off studying for weeks then panicked. the practice labs on evpn overlay config saved me, kept messing up my route targets and the mistake review actually showed me why. passed on first try, still kinda shocked"

"honestly wasnt sure a website could help with something this hands on but expertdataexam.com had enough underlay and DCI scenarios that the real lab didnt feel like a total surprise. six hours is brutal either way, just less brutal prepared"

"studied on and off for like 3 months, kept procrastinating the CoS stuff cause it bored me. the structured plan forced me back to it eventually. glad it did, there was more of it on the exam than i expected"
