Which Cisco IOS command can be issued on a router to test the connectivity of one interface from another interface on the same router?

  • ping (with no address specified)
  • ping (with an address specified)
  • tracert
  • traceroute
Explanation:
The extended ping Cisco IOS utility, which is issued with no address specified, can be issued on a router to test connectivity between two remote routers. The ping utility uses Internet Control Messaging Protocol (ICMP) packets. An ICMP echo request is sent to the destination host. Upon its receipt, the destination host responds to the sending host with an ICMP echo reply. When the echo reply is received, the connectivity is verified. Below is sample output of the extended ping command:

200-301 Part 12 Q01 113
200-301 Part 12 Q01 113

The ping command with an address specified is incorrect because you when you issue this command you will either receive a reply from the destination or a destination unreachable message. It will not prompt for additional information as shown which is what allows you to specify the endpoints for the ping.

The traceroute command is not correct for this scenario because this command traces the path between the host issuing the command and the target network.

The tracert command is not a Cisco IOS command, but a Microsoft command.
