A. The show ip ospf neighbor command on R1 lists the revised Hello timer
B. The show ip ospf interfac e brief command on R1 lists the revised Hello timer
C. The R1 - R2 neighborship fails due to Hello timer mismatcH
D. The show ip ospf interface command on R1 lists the revised Hello timer

Rout er R1 directly connects to subnet 10.1.1.0/24 with its Fa0/0 interface. R1 can ping four other working OSPF routers in that subnet. R1 is neither the designated router (DR) nor backup DR (BDR). OSPF is working correctly on all five routers.
Which of the following is true on R1?（）

D. The show ip ospf neighbors command lists two neighbors off Fa0/0 in the DISCO state.
A. show ip ospf database
B. show ip ospf interface brief
C. show ip protocols
D. show ip route ospf

A router has been configured with the commands router os pf 9, network 172.16.1.0 0.0.0.255 area 8, and network 172.16.0.0 0.0.255.255 area 9, in that order. No other OSPF -related commands have been configured. The answers list the IP addresses that could be assigned to this router's Fa0/0 interface.
Which an swers list an IP address/prefix length that would cause the router to put Fa0/0 into area 9?（）
A. 172.16.0.1/23
B. 172.16.1.1/26
C. 172.16.1.1/24
D. 172.16.0.255/23
E. None of the other answers is correct.
Enterprise Router R1 connects an Enterprise to the Internet. R1 needs to create and advertise a default route into the Enterprise using EIGRP. The engineer creating the implementation plan has chosen to base this default route on the ip route command, rather than using i p default - network.
Which of the following is not a useful step with this style of default route configuration?（）
A. Create the default route on R1 using the ip route 0.0.0.0 0.0.0.0 outgoinginterface command.
B. Redistribute the statically configured defa ult route.
C. Disable auto - summary.
D. Configure the network 0.0.0.0 command.
E. Ensure R1 has no manually configured summary routes using the ip summary- address eigrp command.

Router R1 sits at an Enterprise branch office, using both the Internet and a leased line to another Enterprise router for its two connectivity options back into the rest of the Enterprise network. The engineer planning for this branch decided to use the leased line for all Enterprise traffic, unless it fails, in which case the Internet connection should be used to pass traffic to the Enterprise.Which of the following is most likely to be useful on the branch router?（）
Router R1, a branch router, connects to the Internet using DSL. Some traffic flows through a GRE and IPsec tunnel, over the DSL connection, and into the core of an Enterprise network.
