47.While troubleshooting a connectivity problem, a network administrator notices that a port status LED on a Cisco Catalyst series switch is alternating green and amber. Which condition could this indicate?

A: The port is experiencing errors.
B: The port is administratively disabled.
C: The port is blocked by spanning tree.
D: The port has an active link with normal traffic activity.

Correct Answers: A

48.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

50.Which of the following describe the process identifier that is used to run OSPF on a router? (Choose two.)

A:It is locally significant.
B:It is globally significant.
C:It is needed to identify a unique instance of an OSPF database.
D:It is an optional parameter required only if multiple OSPF processes are running on the router.
E:All routers in the same OSPF area must have the same process ID if they are to exchange routing information.

Correct Answers: A, C
