RE: MCQ

Sergey,
So when you do "match protocol http" without any additional information, protocol-discovery is not required?

The documentation isn't clear to me on this. I've always pinned match protocol to NBAR, my mistake.
http://www.cisco.com/en/US/docs/ios/12_2/qos/command/reference/qrfcmd5.html#wp1066747
match protocol http

To configure Network-Based Application Recognition (NBAR) to match Hypertext Transfer Protocol (HTTP) traffic by URL, HOST, or Multipurpose Internet Mail Extension (MIME)-type, use the match protocol http class-map configuration command. To disable NBAR from matching HTTP traffic by URL, HOST, or MIME-type, use the no form of this command.

match protocol http [url url-string | host hostname-string | mime MIME-type]

no match protocol http [url url-string | host hostname-string | mime MIME-type]
