17.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.
ANSWER: CD
18.How does replacing a hub with a switch affect CSMA/CD behavior in an Ethernet network?

C It decreases the amount of time that a jam signal must be sent to reach all network devices.
D It reduces the total amount of bandwidth available to each device.
E It eliminates Layer 3 broadcast traffic.
ANSWER: A
19.Refer to the exhibit. A problem with network connectivity has been observed. It is suspected that the cable connected to switch port Fa0/9 on Switch1 is disconnected. What
would be an effect of this cable being disconnected?
Ａ Host B would not be able to access the server in VLAN9 until the cable is reconnected.
Ｂ Communication between VLAN3 and the other VLANs would be disabled.
Ｃ The transfer of files from Host B to the server in VLAN9 would be significantly slower.
Ｄ For less than a minute, Host B would not be able to access the server in VLAN9. Then normal network function would resume.
