    1. how will you do san migration of sqlserver clusternodes

    A little vague and will depend on the SAN. Best to speak with the SAN admin and identify exactly what needs to be done and how

    2. wait stats types

    What about them?

    3. how will you do query tuning

    5. blocking occurs what will you do and how will you trouble shoot

    Chapter 6: http://www.red-gate.com/community/books/accidental-dba

    6. 2000 users running how will you find out and rectify the long running query and how will you resolve

    or

    slow running queries and there are 2000 users [process running ] application team complaining application is running slow

    Same way you'd tune for any other number of users.

    how will you rename the instance after moving from A to B node

    You can't rename instances, you can rename the server, in this case the cluster virtual name and that's done through cluster admin or in windows.

    9.without down time i want to move a instance of cluster node A to

    cluster node of B

    Can't be done, there's always downtime, even if it's just a few seconds

If this is for a job interview, remember, you're going to be expected to deal with things like this, on your own, possibly in the middle of the night and that business will be depending on your to ensure they stay online and retain all their data.
