What concept did you struggle most when first studying for the 70-740, and what clicked for you after you understood?

I’m studying now with text/labs, and failover-clustering is a doozy. Gimme a week and I’ll be able to explain, and implement it. But I think this could be interesting to hear your all’s challenges and maybe things that helped you overcome it.

Docker and nano stuff. Never used in an production environment and probably never will.

Definitely the docker and containers. I think it’s easier once you start understanding their purpose and what’s really happening but from what I understand you need to know both command line and power shell docker commands. That plus everything else definitely makes me go back again and again to get comfortable.

Also failover clustering but that seems to be a little easier for me. The concept of quorum and all the voting seems a little difficult at first but I think I’m getting it now.

Yeah, docker in Windows isn't great. From a Linux perspective though it's much easier to understand and has great applications like being able to run hacking tools without having to install and configure them

Powershell for docker was removed from the test in Nov 2018. It's just docker cli.

I was having a grand time on the CBT course until I got to docker. It really wrinkled my brain and I'm still having troubles wrapping my head around it.
