1,You wish to increase the level of availability to the TestKing end users on the network. What is the fundamental
principle behind increasing a network's level of availability?
C. decrease MTTR(mean time to repair) and increase MTBF(mean time between failure)
2,Router TK1 is configured as a DHCP server on the TestKing network. Which command line would you use to report
duplicate address assignments on TK1?
A. debug ip dhcp server events
3,The telnet command is helpful tool in troubleshooting network connectivity. You telnet to router TK1 from a
remote host on the network. What can you conclude from this successful telnet connection?
C. it shows that the TCP/IP protocol stack is available and functioning at the destination
explanation:firstly, if you can telnet then you communicated via an application layer hence you do not have an
application layer issue. Since the telnet program proves that there are no problems all the way to the application
layer, the TCP/IP stack must also be functioning since the application relies on these lower layer in order to
work
4,Which of the following Interet protocols can you use to discover all of the locally attached router addresses?
A. IRDP(ICMP router discovery protocol)
5,What can you expect to achieve from debugging a serial line?
B. Provide diagnostic information relating to protocol status
D. Provide diagnostic information relating to network activity
Debugging a serial line will ultimately tell you whether a protocol is up or down, and it will give you information of what kind of traffic is going through the line.
6,While pinging a Cisco 7513's loopback interface, you notice intermittent drops. What commands should you use to troubleshoot?
A. show diag
B. show buffers
A loopback interface is an internal interface that is always up. The only explanation for the pings only working intermittently would be a problem with the router's hardware or will buffer overflow or leak problems.
7,You enter the following command onto your Cisco Catalyst 5000 switch:
showspan
What are you going to see as a result of it?
D. The switch port being used by a packet analyzer
Show span command is used to display information about the current SPAN(Switched Port Analyzer) configuration. The information includes SPAN source port and SPAN destination port
8,Which command could you use to see the operations of a trunk port on a switch?
B. show trunk
9,While performing a traceroute to a host on the internet, you see a series of "P" replies. In a trace output, what does the letter P signify?
D. the protocol is unreachable
10,You've just finished modifying your routers configuration and want to make the changes permanent. What command would you use to write your new configuration to NVRAM?
B. Write memory
