Couldn't agree more with you.
Use best practice all the time for your CCIE test is the best policy.
Asking the proctor is your life line. 2 points short from passing the
exam will really messed up some of your nerve system..

I think with EIGRP use of exact mask for the prefix is always the best way
to go, i.e. in this example use 10.10.10.0 0.0.0.255 and add passive
interface if required.

Best regards,
Alexei

Do u think network 10.10.10.1 0.0.0.0 more safe? Does Cisco encourage
people
to use it?

to
make an interface passive (meaning not
sending any eigrp advertisement). If memory serves me right, it does not
influence whether an interface would be an eigrp interface or not. If the
interface is listed under the network command and you use passive on that
interface. That interface would still be regarded as an eigrp interface
with no neighbor.

From pass experience, the exact network statement should suffice, however
should you decide to play it safe, it never hurts to put toy around with
passive-interface.
Example,
int e0/0
desc --== EIGRP interface ==--
ip addr 10.10.10.1 255.255.255.0
!
router ei 1
passive-interface default
no passive-interface e0/0
network 10.10.10.0 0.0.0.255
end

UNder EIGRP, when asked only advertise on specical
interface, for example, interface ethernet 0 address 10.10.10.1/24

Is net 10.10.10.0 0.0.0.255 enough?

Do I still need to configure
passive-interface default
no passive-interface ethernet 0
