The following are part of CCNA exam Q&A from www.certay.com. You can go to certay and consult live-support for more information if you are interested in its products. Now let’s look at the following study-guides offered by certay.
1. Why has the network shown in the exhibit failed to converge?
A: The no auto-summary command needs to be applied to the routers.
B: The network numbers have not been properly configured on the routers.
C: The subnet masks for the network numbers have not been properly configured.
D: The autonomous system number has not been properly configured.
E: The bandwidth values have not been properly configured on the serial interfaces.
Correct Answers: A
2. Refer to the exhibit. The network shown in the exhibit is running the RIPv2 routing protocol. The network has converged, and the routers in this network are functioning properly. The FastEthernet0/0 interface on R1 goes down. In which two ways will the routers in this network respond to this change? (Choose two.)
A: All routers will reference their topology database to determine if any backup routes to the 192.168.1.0 network are known.
B: Routers R2 and R3 mark the route as inaccessible and will not accept any further routing updates from R1 until their hold-down timers expire.
C: Because of the split-horizon rule, router R2 will be prevented from sending erroneous information to R1 about connectivity to the 192.168.1.0 network.
D: When router R2 learns from R1 that the link to the 192.168.1.0 network has been lost, R2 will respond by sending a route back to R1 with an infinite metric to the 192.168.1.0 network.
E: R1 will send LSAs to R2 and R3 informing them of this change, and then all routers will send periodic updates at an increased rate until the network again converges.
Correct Answers: C, D
3. The network administrator of the Oregon router adds the following command to the router configuration: ip route 192.168.12.0 255.255.255.0 172.16.12.1. What are the results of adding this command? (Choose two.)
A: The command establishes a static route.
B: The command invokes a dynamic routing protocol for 192.168.12.0.
C: Traffic for network 192.168.12.0 is forwarded to 172.16.12.1.
D: Traffic for all networks is forwarded to 172.16.12.1.
E: This route is automatically propagated throughout the entire network.
F:Traffic for network 172.16.12.0 is forwarded to the 192.168.12.0 network.
Correct Answers: A, C
