Hello, I saw a question on sample question bank which is not touched upon in PMBOK. It was related to : Situational leadership model as defined by Paul Hersey and Ken Blanchard
How much chances are there where out of book questions like this comes.
However, this is mentioned in eRead section http://pmi.books24x7.com/assetviewer.aspx?bookid=8645&chunkid=0921290582&rowid=566
