The question is correct.

I got it wrong because I always refer to it as mssqlsystemresource and thought 'resource' was incorrect shorthand, but turns out microsoft refer to it as the resource database, so I have learnt something and in future will refer to it as 'resource', thus saving myself the effort of saying 'mssqlsystemresource' which does not roll off the tongue.

And this post gets me my point back 🙂
