Your company provides managed services for two customers. Each customer has been
segregated within its own routing instance on your SRX device. Customer A and customer B
inform you that they need to be able to reach certain hosts on each other’s network.
Which two configuration settings would be used to share routes between these routing instances?
(Choose two.)
A.
routing-group
B.
instance-import
C.
import-rib
D.
next-table
Explanation:
Reference :http://aconaway.com/2013/03/02/junos-logical-tunnel-interfaces-with-virtual-routers/
Advanced Security book 1 page 129:
– Use RIB groups to share routes between routing tables.
– Other options for sharing routs between routing instances exist. You can use the instance-import, instance-export and auto-export configuration options to share routes between multiple routing instances and eliminate the configuration of separate routing table groups on each instance.
So answers should be b and c.

Ignore my above comment here. Correct answer is B & D.
This question is asking “need to be able to reach certain hosts on each other’s network” – here the trick goes; you need to leak “certain routes” only and NOT whole routing table to each other.
Only “instance-import” and and “next-table with static route” does support “Term with route-filter” to specify specific networks/hosts.
“import-rib” does not comes with term and route-filter – “C”.
“A” is never correct as there is no such thing called “routing-group”; there is one called rib-group.
