For me, it was the fact that I'd never actually gone through an AutoDeploy setup. I mean, Enterprise Plus license level only with large shops that are deploying massive hosts? Not used often. I use the ESX Deployment Appliance. The every-person's version of kickstart for ESXi systems. I love EDA.
Anyway. The test could sense that I had skimmed the AutoDeploy documentation. I'm sure it has sensed fear from others on different subjects. A respectable 400 considering that I probably missed all the autodeploy questions.
And I totally stole and modified the VCP button. VCP#22708 on 3,4&5. VCAP5-DCD next.
