I have installed a DC – Let’s call it as DC1 I have installed a Second DC using (Additional Domain Controller for an existing domain controller option) – Let’s call it as DC2 Can anyone tell me 1) What are the FSMO roles running on DC1 and what are the roles running on DC2? 2) Which one will be GC by default? 3) If DC1 goes down, will DC2 take over automatically? Or do we need to transfer(seize) the roles to Dc2? If we need to transfer (seize) roles, which of the roles? 4) What about GC if DC1 goes down? Pleas help me out -

Do your homework. This isnt the type of question you should be asking on a forum like this. What you should be doing is surfing technet or Google to find that answer. No one here is going to be able to tell you what FSMO roles your DC holds because you can only find that out by running a command from a command prompt on those said servers. Likewise if you checked in AD you would see wether the DC's are Global Catalogues or not. If you dont know what your doing its time for you to open a book and find out how.

CurtR answered those questions in your previous post. For review: Q1 google fsmo roles for the list of five roles Q2 DC1 Q3 No Yes All roles Q4 If DC1 goes down you have no GC which is why you want to review MS recommendations.

DC1 held all the roles because it was the only DC originally. Sounds like a test question to me. How about you put a little work into this on your own?
