There is a connectivity problem between the serial 0/0 interface of router TESTKING1 and the serial 0/0 interface of TESTKING2. A leased line point to point circuit is installed between these two routers. The output from the "show interface serial 0/0" command is displayed below for each of these routers:
From your observations of the above exhibit, what is the underlying cause of the problem?（）
A. The loopback is not set.
B. The serial cable is faulty.
C. The subnet mask is not configured properly.
D. The IP address is not configured properly.
E. The Layer 2 frame types are not compatible.
F. The keepalive setting is not configured properly.

The relevant configuration files for the TestKing1 and TestKing2 routers are displayed below:
With due consideration to the command outputs, which of the following reasons would you attribute the connectivity problem between the two routers?（）
A. The authentication needs to be changed to PAP for both routers.
B. The serial IP addresses of routers are not on the same subnet.
C. The username/password combination is incorrectly configured.
D. The router names are incorrectly configured.
A. ICMP echo request

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
