Refer to the exhibit. The partial configuration for an OSPF ASBR and an Area 0 ABR is shown. Assume the OSPF configurations throughout the network are operable. Which statement about these configurations is true? （）
A. The ASBR route - maps are basically useless, because there are no deny prefix - lists.
B. LSA Type 5s wil l not be received by the ABR from the ASBR.
C. The OSPF backbone will not learn any RFC 1918 addresses.
D. The matched prefix - list addresses will be given a metric of 255, which is essentially unreachable.

D. ASBR Summary LSA （ Type = 4 ）
E. AS External LSA （ Type = 5 ）
第8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.
