There's something strange with this one.
You've specified +norec on command line, but the query was sent with 'rd' - 
'recursion desired' flag, as if you haven't given +norec. And with recursion 
giving answer is perfectly legal. If not for that flag, then yes, I'd 
consider it a lame response, although probably someone more knowledgeable 
than me should judge this.
