   So, I’m a little confused. On the juniper website http://www.juniper.net/techpubs/en_US/junos10.4/topics/reference/general/policy-routing-policy-match-conditions.html

   It says that you can match “Prefix list—A named list of IP addresses.”
   and in the “Standard—A collection of criteria that can match a route.” it says “Match a route based on one of the following criteria:” “area ID” and ” interface name”, doesn’t that make 3 answers valid to this question?

      By default routing is done at layer 3. So you can safely eliminate C which is found in Layer 4. It is not all the fields in packet header that can be evaluated and I suspect ttl is one of them, Hence AB should be correct.
