   Two OSPFv3 routers on a broadcast segment are stuck in the ExStart state. The engineer checks the MTU on both interfaces and finds they are both 1500. Which other parameter, visible in the Database Description (DD) packets, could be preventing the adjacency from progressing?

   • AThe OSPFv3 interface cost is different on the two routers
   • BThe OSPFv3 area ID is different on the two routers
   • CThe OSPFv3 router ID is the same on both routers
   • DThe OSPFv3 dead interval is different on the two routers

   A Junos router in an OSPFv3 network has interfaces in both area 0 and area 1. The network administrator wants to reduce the size of the link-state database in area 1 by preventing Type 4 and Type 5 LSAs from being flooded into it. Which OSPFv3 area type should be configured for area 1?

   • ABackbone area
   • BNot-so-stubby area (NSSA)
   • CStub area
   • DTotally stubby area

   An OSPFv3 network has a router that is an ASBR redistributing static IPv6 routes into OSPFv3. The network administrator notices that the external routes are not being installed in the routing table of routers in a remote area. The remote area is configured as a stub area. What is the most likely reason for the missing routes?

   • AThe external routes are not being advertised because the ASBR is not in the backbone area
   • BThe stub area does not accept Type 5 LSAs, so external routes are not flooded into it
   • CThe ASBR is not generating Type 7 LSAs for the stub area
   • DThe ABR is not summarizing the external routes into the stub area
