A. B. C. D.A
ping atm syntax:
Syntax -
ping atm interface interface-name vci vci
<brief>
<count count>
<end-to-end | segment>
<interval seconds>
<sequence-number sequence-number>
The correct answer to the question is option C, "ping atm vci 0.100 interface at-0/1/0 far-end."
When troubleshooting ATM (Asynchronous Transfer Mode) networks, testing reachability from one side of an ATM cloud to the other can be done using the ATM ping command. The ATM ping command is used to test end-to-end connectivity between two ATM endpoints by sending a series of ATM cells between them.
In the given options, the command "ping atm vci 0.100 interface at-0/1/0 far-end" is the correct one to use for testing reachability from one side of the ATM cloud to the other. This command sends an ATM ping request to the far-end of the specified interface and VCI (Virtual Circuit Identifier) to check if the remote endpoint is reachable.
Option A, "ping atm vci 0.100 interface at-0/1/0 end-to-end," is incorrect because it does not specify the destination endpoint and only tests connectivity between the local and remote endpoints.
Option B, "ping atm vci 0.100 interface at-0/1/0 circuit," is incorrect because it only tests connectivity between the local endpoint and the first hop in the ATM cloud.
Option D, "ping atm vci 0.100 interface at-0/1/0 final-hop," is incorrect because it only tests connectivity between the local endpoint and the last hop in the ATM cloud.
Therefore, option C is the correct command to use when troubleshooting ATM to test reachability from one side of the ATM cloud to the other.
