What is the correct syntax to use when testing connectivity to 10.1.2.2 by sending 100 consecutive quick pings?

The syntax for testing connectivity to an IP address by sending 100 consecutive quick pings is correct in the option that includes the term "rapid" along with the specify count parameter. In networking, particularly in Juniper devices, the "rapid" keyword indicates that the pings are sent in a quick succession, which is part of making the test more responsive and efficient for checking connectivity.

The count parameter specifies the number of pings to send, and in this case, it is set to 100. This combination effectively instructs the device to rapidly send out 100 ping requests to the specified IP address, thus testing the connectivity efficiently.

Using "rapid" allows for rapid-fire pings that help in scenarios where a quick determination of connectivity is necessary. Other variations of ping command without the "rapid" specification might not convey the same urgency or reduced delay between sending out pings, which is vital for performance testing in certain conditions.
