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? ()<br /> <img src="https://nimg.ppkao.com/2018-07/yiyu/2018073016383587423.jpg?sign=63c2c6142490bb10edf2ec0897cfce25&t=62d09a2d" />
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.
