I have been studying for my VCAP-DCD and I must say the amount of material referenced for the exam can seem overwhelming. While going through official documentation and whitepapers is fairly straightforward, I find locating relevant KB articles to be quite the task. As such, I have put together a list of KB articles I think are worth going over. Instead of breaking down the KB articles by objectives I have decided to list them by component.
