第2题：
You are troubleshooting an OSPF problem where external routes are not showing up in the OSPF database. Which two options a re valid checks that should be performed first to verify proper OSPF operation?（）
A. Are the ASBRs trying to redistribute the external routes into a totally stubby area?
B. Are the ABRs configured with stubby areas?
C. Is the subnets keyword being used with the redistribution command?
D. Is backbone area (area 0) contiguous?
E. Is the CPU utilization of the routers high?
第3题：
An OSPF non-backbone area allows external routes to be flooded within the area. These externalroutes are propagated into other areas. However, external routes from other areas are not allowed to enter this area. Which type of OSPF area does this describe?（）
A. stub area
B. transit area
C. border area
D. not-so-stubby area
第4题：
When an OSPF design is planned, which implementation can help a router not have memory resource issues?（）
第5题：
A. The map prohibits th e redistribution of all type 2 external OSPF routes.
B. All routes that do no match clauses 10 and 20 of the route map are redistributed with their tags set to 8.
C. The map prohibits the redistribution of all external OSPF routes with tag 6 set.
D. Th e map permits the redistribution of all type 1 external OSPF routes.
E. The map redistributes into EIGRP all routes that match the pfx prefix list and the five metric values?0000, 1000, 255, 1, and 1500.
F. The map prohibits the redistribution of all ty pe 2 external OSPF routes with tag 6 set.
第6题：
A. RIP routes will be allowed in Area 1 only if they are first redistributed into EIGRP.
B. Because NSSA will discard type 7 LSAs, redistributed RIP routes will not be allowed in Area 1.
C. Redistrib uted RIP routes will be allowed in Area 1 because they will be changed into type 5 LSAs in Area 0 and passed on into Area 1.
D. Redistributed RIP routes will be allowed in Area 1 because they will be changed into type 7 LSAs in Area 0 and passed on into Area 1.
E. Because Area 1 is an NSSA, redistributed RIP routes will not be allowed.
第7题：
A. Have a backbone area (area 0) with 40 routers and use default routes to reach external destinations
B. Have a backbo ne area (area 0) with 4 routers and 30,000 external routes injected into OSPF
C. Have less OSPF areas to reduce the need for interarea route summarizations
D. Have multiple OSPF processes on each OSPF router. Example, router ospf 1, router ospf 2
第8题：
A. Routers cannot redistribute external routes into the area.
B. Routers should have zero Type 3 LSAs in their LSDBs.
C. Routers should have zero Type 5 LSAs in their LSDBs.
D. Routers should learn default routes from the ABRs attached to the area.
第9题：
