    I notice questions in my 70-270 practise exams mention this frequently although it never seems to be the answer.
    Tend to be along the lines of dual proccessor machines running older application and cpu usage is 90% on one and 10% on other. The answer is always run the application in seperator memory space but what is CPU affinity and when would you use it?

    its to do with what processor you wish to assign the processor too
    perhaps you waht to assign a heavy database query to one processor, or a compile job, as you know it will quite happily take ALL the processor power if you dont, and leave the spare one free

    to be honest, ive worked in some environments with pretty intense database reporting and querying, 8 processor boxes, 32 processor boxes, and we never set the affinity lol

    saying that, it could of just been a noob dba, but i couldnt say :)
