There is NOBODY on this forum that is going to even attempt to answer all of these questions. They look like interview or exam type questions which can be answered by yourself by using the .pdf manuals. Mostly NBU Admin Guide I and Status Code Guide. Even Google and this forum. You can find links to all manuals in 'Handy NBU links ' in my signature.
