A. B. C. D.C
The "ping" command is used to test network connectivity between two hosts using the ICMP protocol. The Junos OS supports the "ping" command, which can be used to test the connectivity between two devices on a network. The "ping" command sends ICMP echo requests to the target host and waits for the ICMP echo replies to come back.
The command "ping interface t1-1/1/0 1.1.1.1 bypass-routing count 1000 rapid" is used to send ICMP echo requests to the host with IP address 1.1.1.1 through the T1 interface t1-1/1/0. The "bypass-routing" parameter is used to bypass the routing table and send the ICMP echo requests directly through the specified interface.
Now let's examine each of the answer choices:
A. The bypass-routing parameter is used to test the density on the T1 line. This statement is incorrect. The "bypass-routing" parameter is used to bypass the routing table and send the ICMP echo requests directly through the specified interface. It has nothing to do with testing the density on the T1 line.
B. The bypass-routing parameter cannot be used on a T1 interface. This statement is incorrect. The "bypass-routing" parameter can be used on any interface, including T1 interfaces.
C. The bypass-routing parameter allows you to ping a host through an interface that has no route through it. This statement is correct. The "bypass-routing" parameter allows you to send ICMP echo requests directly through the specified interface, even if there is no route to the destination host through that interface.
D. The bypass-routing parameter allows you to ping a local WAN interface without generating any outbound traffic. This statement is incorrect. The "bypass-routing" parameter does not allow you to ping a local WAN interface without generating any outbound traffic. It simply allows you to send ICMP echo requests directly through the specified interface, bypassing the routing table.
Therefore, the correct answer is C: The bypass-routing parameter allows you to ping a host through an interface that has no route through it.
