第4题：
R1 is internal to area 1, and R2 is internal to area 2. Subnet 10.1.1.0/24 exists in area 2 as a connected subnet off R2. ABR ABR1 connects area 1 to backbone area 0, and ABR2 c onnects area 0 to area 2. Which of the following LSAs must R1 use when calculating R1's best route for 10.1.1.0/24?（）
- A、R2's Type 1 LSA
- B、Subnet 10.1.1.0/24's Type 2 LSA
- C、ABR1's Type 1 LSA in area 0
- D、Subnet 10.1.1.0/24's Type 3 LSA in Area 0
- E、 Subnet 10.1.1.0/24's Type 3 LSA in Area 1

第5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.
正确答案:B
第6题：
On Router R1, process EIGRP 1 is redistributing routes from process OSPF 2, calling route - map fred with the redistribute ospf 2 command. R1 has learned intra - area routes for 10.1.1.0/24 and10.1.2.0/24 in part due to the Type 2 LSAs known for each subnet. The route map filters route 10.1.1.0/24 and allows 10.1.2.0/24 througH.Which of the following co mmands on router R1 list subnet 10.1.1.0/24?（）
A. show ip route
B. show ip eigrp topology
C. show ip ospf topology
D. show ip eigrp topology 10.1.1.0/24

- C、R1 advertises a 1 0.1.0.0/16 route into area 1 with a metric of 23 (largest metric).
- D、R1 advertises a 10.1.0.0/16 route into area 1 with metric of 21 (lowest metric).

第10题：
In which of the following scenarios would the "show cdp neighbors detail"command be an appropriate troubleshooting tool?（）
- A、Two switches are connected via a trunk. Both switches have been assigned an IP address, subnet mask, and default gateway. A ping is successful between the two switches. However, VLAN information is not passed from one switch to the other switch.
- B、A router and a switch have been assigned an IP address, a subnet mask, and a default gateway. They are directly connected, but a ping between the two devices fails.
- C、A router connects to another router through a serial interface. Both routers have been assigned an IP address, subnet mask, and default gateway. The routers are running RIP and the networks directly connected to the first router do not pass to the second router. However, a ping from one router to the serial interface of the directly connected neighboring router is successful.
- D、A router connects to another router via a switch. Both routers and the switch have been assigned an IP address, subnet mask, and default gateway. Neither the routers nor the switch are able to ping one of the hosts that is directly to the switch.
正确答案:B
