I am confused, I am trying to start self study for CCNP. I've had a look at cisco website and it lists the requirements. BSCI 642-801, BCMSN 642-811, BCRAN 642-821, and CIT 642-831. I attempted to buy a book for the BSCI exam and found it had the number 642-901. I didn't buy the book as CISCO say the exam is 642-801. Does this mean the exam is about to change? Can anyone recommend a good self study guide.
