Cisco CCNA mock exam questions sample test – Question 124

.What command produced the following as a part of its output?

1 14.0.0.2 4 msec 4 msec 4 msec
2 63.0.0.3 20 msec 16 msec 16 msec
3 33.0.0.4 16 msec * 16 msec

A. Ping
B. Traceroute
C. Tracert
D. Extended ping

Correct Answer: B

Explanation:
The output displayed is a part of the output from executing the traceroute command. The traceroute command finds the path a packet takes while being transmitted to a remote
destination. It is also used to track down routing loops or errors in a network. Each of the following numbered sections represents a router being traversed and the time the packet took
to go through the router:
1 14.0.0.2 4 msec 4 msec 4 msec
2 63.0.0.3 20 msec 16 msec 16 msec
3 33.0.0.4 16 msec * 16 msec
The output would not be displayed by the ping command. This command is used to test connectivity to a remote ip address. The output from the ping command is as follows:
router1# ping 10.201.1.11
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.201.1.11, timeout is 2 seconds:
…..
Success rate is 0 percent (0/5)
The ping in this output was unsuccessful, as indicated by the Success rate is 0 percent output.
The output would not be displayed by the tracert command. The tracert command is used by Microsoft Windows operating systems, not the Cisco IOS command line interface.
However, the purpose of the tracert command is similar to the Cisco traceroute utility, which is to test the connectivity or “reachability” of a network device or host. The tracert
command uses Internet Control Message Protocol (ICMP).
The output would not be displayed by the extended version of the ping command. This command can be issued on the router to test connectivity between two remote routers. A
remote execution means that you are not executing the command from either of the two routers you are interested in testing, but from a third router.
To execute an extended ping, enter the ping command from the privileged EXEC command line without specifying the target IP address. The command takes the router into
configuration mode, where you can define various parameters, including the destination and target IP addresses. An example is below:
Protocol [ip]:
Target IP address: 10.10.10.1
Repeat count [5]:
Datagram size [100]:
Timeout in seconds [2]:
Extended commands [n]: y
Source address or interface: 12.1.10.2
Type of service [0]:
Set DF bit in IP header? [no]:
Validate reply data? [no]:
Data pattern [0xABCD]:
Loose, Strict, Record, Timestamp, Verbose[none]:
Sweep range of sizes [n]:
Type escape sequence to abort.
Each line is a menu question allowing you to either accept the default setting (in parenthesis) of the ping or apply a different setting. The real value of this command is that you can test
connectivity between two remote routers without being physically present at those routers, as would be required with the standard version of the ping command.
