Hi

Passive interface has nothing to do when you are announcing networks in
your network command, but like any routing protocol eigrp will send
hello's over those networks and normally you have hosts on those
segments, if you want to supress sending and receiving hello's on those
specific interface's (mind it only works on EIGRP passive, i mean send
and receive) you should use passive interface.

So the bottom line is if they as us in the exam not to sending routing
updates, or hello's on those interface we are supposed to use passive,
other wise let it be as it is.

I hope this is what you were asking
