Refer to the exhibit. A student is responsible for the IP addressing, configuration and connectivity testing of the network shown in the graphic. A ping from host B to host C results in a destination unreachable but a ping from host B to host A was successful. What two reasons could account for this failure based on the graphic and partial router output for the Dallas router? (Choose two.)
The host A is turned off.
The Fa0/0 interface on Dallas is shutdown.
The LAN cable is disconnected from host B.
The S0/0/1 IP address of Dallas is improperly configured.
The Fa0/0 interface on Dallas is in a different subnet than host B.
The clock rate is missing on the serial link between Dallas and NYC.
The connection between routers B and C has been successfully tested. However, after rebooting router C, the administrator noticed the response time between networks 10.10.3.0 and 10.10.4.0 is slower. Ping between the two routers is successful. A trace route indicates three hops from router B to router C. What else can be done to troubleshoot the problem?
Ping router B S0/1 connection from router C.
Trace the connection between router B to router C S0/1.
Issue a show ip route command in router B to verify routing is enabled.
Issue a show interfaces command on router C.
