JN0-102 · Question #215
You issue the ping interface t1-1/1/0 1.1.1.1 bypass-routing count 1000 rapid command. Which statement is correct?
The correct answer is C. The bypass-routing parameter allows you to ping a host through an interface that has no route through it.. This question focuses on the purpose of the bypass-routing parameter when used with the Junos OS ping command.

Why each option
This question focuses on the purpose of the `bypass-routing` parameter when used with the Junos OS `ping` command.
The `bypass-routing` parameter is unrelated to testing line density.
The `bypass-routing` parameter can be used on any outbound interface, including T1 interfaces.
The `bypass-routing` parameter instructs the Junos OS device to send the ICMP echo request directly out the specified interface, even if there is no matching route in the routing table for the destination IP address. This is useful for testing direct connectivity to a neighbor that might not be fully routed yet or for verifying link integrity without relying on routing protocols.
The `bypass-routing` parameter causes outbound traffic to be generated through the specified interface towards the destination IP, not prevents it.
