I've recently taken and aced my 220-801 exam, WHOLLY thanks to you guys. I'd like to add, my exam called out the explicit formats of IPV6 including IDing loopback and link local addressing. I'm not sure if these have since been updated but it wasn't covered in the video course, it was however including in the practice test subscription you include, so again massive thanks. Blasting through the 802 as we speak. Can't wait to move onto Network+ !!
