The following output exists on Router R1, a router internal to area 1. What can you d etermine as true from the output of the show ip ospf database summary command?() A. The LSA was created by an ABR due to an area range command.B. The LSA was created by an ASBR due to a summary - address command.C. If cr eated by an area range command, the best metric for a subordinate subnet on that ABR must have been 11.D. None of the other answers is correct.
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.
Refer to the exhibit. Which statement is true about the configuration? () A. RTA will not establish an OSPF adjacency w ith RTBB. RTA will send OSPF hello packets, but will not send OSPF updatesC. RTA will not accept OSPF hello packets from RTBD. RTA will send OSPF updates, but will not establish an adjacency with RTB
