一台运行OSPF的路由器，它的两个正常工作的接口一个属于区域0，另一个属于区域9，并且重分布5条静态路由进入OSPF，则该路由器一定会始发哪些LSA（）A.Router LSA（Type=1）；B.Network LSA（Type=2）；C.Network Summary LSA（Type=3）；D.ASBR Summary LSA（Type=4）；E.ASE xternal LSA（Type=5）；
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.

Which two statements are true about IS -IS routing?（）A、Based on the default timers, OSPF d etects a failure faster than IS - IS does.B、OSPF default timers permit more tuning than IS - IS does.C、IS - IS is more efficient than OSPF in the use of CPU resources.D、OSPF is more scalable than IS - IS because of its ability to identify normal, stub, an d NSSA areas.E、IS - IS and OSPF are both Open Standard, link - state routing protocols which support VLSM.
