[j-nsp] JNCIP question: eBGP policy

[Min]

hey guys, I have a few reqestions during studying JNCIP book. hopefull
someone can help here.

1. Can I safely assume and configure following annoucing policy since
it's the way in the real world:
    " send cust routes to transit and peer, send peer routes to cust,
sent transit routes to cust. "

I noticed sometimes JNCIP question doesn't require one or some of
them, is it ok for me to implement all? sometimes it's required that
"send peer routes to transit", I know even it's not in real world, I
have to follow what required.

2. in practice, we normally define eBGP import policy like this:
[ generic-filter-in generic-community-setup community-setup-as65050
prefer-peer ]

generic-filter-in and generic-community shared by all ebgp import
policy on this router; prefer-peer shared by all peer ebgp import
policy, community-setup-as65050 tags peer specific community.

with extra requirement for some peers, one or some of these policy [
as65050-filter-in no-comms damping prepend-twice ] will be added to
policy chain.

I'm wondering if this is a good policy formation for JNCIP test?
