You are the network administrator for your company. You are in the process of verifying the configuration of the network devices to ensure smooth network connectivity. You want information on the routes taken by packets so that you are able to identify the network points where packets are getting dropped.
Which Cisco IOS command should you use to accomplish this task in the most efficient manner?
A. tracert
B. traceroute
C. extended ping
D. ping
Correct Answer: B
Explanation:
You should use 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.
The tracert command is incorrect because this 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, namely to test the connectivity or “reachability” of a network device or host. The tracert command uses Internet Control Message Protocol (ICMP).
The extended ping Cisco IOS command can be issued on a router to test connectivity between two remote routers. This option is incorrect because you are not testing connectivity in this scenario; you want to determine the route a packet takes through the internetwork.
The ping command is also incorrect because you are not testing connectivity in this scenario; you want to determine the route a packet takes through the internetwork.
