The Testking router is running RIP as the routing protocol, and the IP routing table is displayed below:
Gateway of last resort is 10.1.2.2 to network 0.0.0.0
10.0.0.0/24 is subnetted, 2 subnets
R 10.1.3.0 [120/1] via 10.1.2.2, 00:00:00, Serial0/0
C 10.1.2.0 is directly connected, Serial0/0
C 10.1.5.0 is directly connected, Serial0/1
C 10.1.6.0 is directly connected, FastEthernet0/0
R* 0.0.0.0/0 [120/1] via 10.1.5.5, 00:00:00, Serial0/1
Based on the output above, if an administrator pings host 10.1.8.5 from host
10.1.6.100, how will the router TestkingA process the ICMP packets?（）
A. The packets will be discarded.
B. The packets will be routed out the S0/0 interface.
C. The packets will be routed out the S0/1 interface.
D. The packets will be routed out the Fa0/0 interface.
E. The packets will be routed through the 10.1.2.2 gateway.
A. duplex mismatch
B. a routing loop
C. trunking mode mismatch
D. improperly configured root bridge
E. improperly configured static VLAN
While troubleshooting connectivity issues, you log into a remote router. From there,you wish to see the layer 1 and layer 2 status of the interface.
Which of the following IOS commands would you issue to check the current IP addressing, as well as theyer 1 and layer 2 status of an interface?（）
A. TK1# show version
B. TK1# show protocols
C. TK1# show interfaces
D. TK1# show controllers
E. TK1# show ip interface
F. TK1# show startup-config
While troubleshooting a connectivity issue from a PC you obtain the following information:
Local PC IP address: 190.0.3.35/24
Default Gateway: 190.0.3.1
Remote Server: 190.0.5.250/24
You then conduct the following tests from the local PC:
Ping 127.0.0.1 - Unsuccessful
Ping 190.0.3.35 - Successful
Ping 190.0.3.1 - Unsuccessful
Ping 190.0.5.250 - Unsuccessful
What is the underlying cause of this problem?（）
A. TCP/IP not correctly installed
B. Local physical layer problem
C. NIC not functioning
D. Remote physical layer problem
