As other MVA video series, It has some little assessment between lessons. On one of them has a tricky question, so I should note that. You map a custom domain name to an organizational domain name by adding a TXT(not CNAME) record at your DNS host.
Also, instructor mention about good sources. Like ScottGu's Blog and Azure Friday. Yet I don't want to comment about them. I will investigate follow them soon.
