What difference between 1z0-071 and 1z0-061 ?

Hello ;
I have searched in here and Google but nothing. Is there anyone to tell about difference 1z0-071 and 1z0-061 ?
I will take an exam but I can't decide which to take one.

And also I have a book for 1z0-061. So If you suggest me to take 1z0-071 exam, do you think that 1z0-061 book is enough for 71 exam?

Thank you for your help.
