The commands ping and traceroute send messages in the network to test connectivity and rely on other devices to send back a reply.

(A) TRUE
(B) FALSE

TRUE is the correct answer.

ping and traceroute commands help network engineers isolate problems. Here is a comparison of the two:
1. Both send messages in the network to test connectivity.
2. Both rely on other devices to send back a reply.
3. Both have wide support on many different operating systems.
4. Both can use a hostname or an IP address to identify the destination.
5. On routers, both have a standard and extended version, allowing better testing of the reverse route.
