考题
Which of the following can either directly or indirec tly identify all the interfaces for which both 1) OSPF has been enabled and 2) OSPF is not passive?()
A. show ip ospf databaseB. show ip ospf interface briefC. show ip protocolsD. show ip route ospfE. show ip ospf neighbors
考题
The administrator wants to verify the current state of the OSPF database loading process. Which show command should the administrator use?()
A. show ip ospf [process - id] interfaceB. show ip ospf neighborC. show ip ospf [process - id]D. show ip ospf [process - id area - id] database
考题
Refer to the exhibit. You have completed an OSPF implementation, and you are verifying OSPF operation. You notice that router A and router B are stuck in the two - way state. From the show ip ospf interface command output, what is the cause of this issue?（）A. All OSPF implementations must have at le ast one interface in area 0.B. You are attempting to run in the broadcast mode over an NBMA interface.C. Both routers are configured to function as a BDR; therefore, there is no DR router.D. Someone has changed the OSPF router ID; therefore you must clear the OSPF process.E. The OSPF priority is set to 0 on both routers; therefore neither can become the DR.

考题
Router R1 has a connected route for 10.1.1.0/24 off interface Fa0/0. Interface Fa0/0 has been enabled for OSPF due to a router ospf 1 and network 10.0.0.0 0.0.0.255 area 0 command. R1 also has EIGRP configured, with the redistribute ospf 1 metric 1000 100 10 1 1500 command configured under EIGRP. Which one of the following is true?（）A、R1 will not redistribute 10.1.1.0/24 into EIGRP, because R1 knows it as a connected route and not as an OSPF route.B、For any OS PF routes redistributed into EIGRP, the metric components includea value equivalent to 1 Mbps of bandwidth.C、For any OSPF routes redistributed into EIGRP, the metric components include a value equivalent to 100 microseconds of delay.D、No subnets of network 10.0.0.0 will be redistributed due to the omission of the subnets parameter.
