Confused on on of the ?  on the practice exam E20-598.  They mention a 1x5+1  Avamar Grid and ask you the maximnum # of connections.

I thought that s/b  27 connections per Data Node.  so 27X5 = 135 ...  But the correct answer according to the test is 134 ?

Not understanding what I'm missing here.  Is the test correct and everything I have read is wrong?

each node is capable of 28 connections so there are some connections remaining for restores.

Thanks in advance for any assistance.

I think I found the answer!  During the normal backup window.   

(v6.1) 27 jobs per data node (less one for the overall grid for restore) and a maximum of 480 for the grid

•    One restore for the entire grid 

• so on a 1X16+1   answer is 431.
