Correct Answer: AB
The issue is that router R3, located in NSSA Area 1, cannot reach the loopback interface on router R2. The loopback interface 192.168.3.1 is part of OSPF Area 0. Because NSSA areas do not automatically receive external routes or summary routes from other areas by default, an additional configuration is often required to propagate the routes correctly. By adding the 'originate-default-route' option in the NSSA area configuration on router R3, you enable the injection of a default route into the NSSA area, allowing R3 to recognize the route to 192.168.3.1. This solution ensures that the route is present in the routing table, leading to successful communication with the loopback interface.
