 |

B. Router C will use ICMP to inform Router B that Host 2 cannot be reached.
C. Router C will use ICMP to inform Host 1, Router A, and Router B that Host 2 cannot be reached.
D. Router C will send a Destination Unreachable message type.
E. Router C will send a Router Selection message type.

B. 172.16.0.1
C. 192.168.0.5
D. 223.0.0.1

39. 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.
Answer: A
40. 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.
