A. Two switches are connected via a trunk. Both switches have been assigned an IP address, subnet mask, and default gateway. A ping is successful between the two switches. However, VLAN information is not passed from one switch to the other switch.
B. A router and a switch have been assigned an IP address, a subnet mask, and a default gateway. They are directly connected, but a ping between the two devices fails.
C. A router connects to another router through a serial interface. Both routers have been assigned an IP address, subnet mask, and default gateway. The routers are running RIP and the networks directly connected to the first router do not pass to the second router. However, a ping from one router to the serial interface of the directly connected neighboring router is successful.
D. A router connects to another router via a switch. Both routers and the switch have been assigned an IP address, subnet mask, and default gateway. Neither the routers nor the switch are able to ping one of the hosts that is directly to the switch.
A. show interfaces serial 0/0
B. show running-config
C. show version
D. show controllers serial 0/0
E. show ip interface
F. show line serial 0/0
TestKing.com is configuring the serial interface of a Cisco router to connect to the router of a new ISP. A full T1 is being used for the Internet connection. After issuing the show interface serial 0/0 command, it is observed that the interface is UP and the line protocol is DOWN.
Which of the following commands could fix this problem?（）
A. Border# copy running-config startup-config
B. Border(config)# no shutdown
C. Border(config-if)# encapsulation ppp
D. Border(config-if)# no cdp enable
E. Border(config-if)# ip routing
You have just installed a new web server on the Testking network. You are required to ensure that the web server is accessible from the Internet. The network uses private addressing, so an IP-to-registered address mapping is required.To do this, you enter the following command:TestKing(config)# ip nat inside source static 192.168.2.1 198.18.1.254 You unsuccessfully try to ping the Internet from a PC host on the LAN. During the troubleshooting process, you enter the "show ip nat translations" command but the output is blank.
What is the most likely cause of the problem?（）
A. The keyword overload is missing from the command.
B. The NAT pool must be defined first.
C. An access list must be defined to create static NAT translations.
D. The interfaces must be configured for NAT.
E. None of the above
A. The IP addresses are configured incorrectly.
B. Frame Relay LMI messages not displayed in real time.
C. The administrator must issue the enable frame-relay lmi debug command.
D. The administrator must issue the terminal monitor command.
E. Debug messages can only be received once through the console port.
F. The administrator must issue the show frame-relay lmi vty 0 4 command
You are troubleshooting a WAN connection for TestKing, and on the router you execute the, "debug ppp authentication" command, and view the following output:
What kind of handshake was used for the PPP authentication?（）
A. one-way
B. two-way
C. three-way
D. No handshakes required during authentication
E. None of the above
