Which of the following troubleshooting tools tells how many hops to the
destination computer? Correct Ans - tracert.
To determine the path your IP packets take to reach a remote office router,
you issue the tracert command from a local network host, targeted at the
remote office router's outside interface. Previous tracert replies showed the
router nine hops away, so you set the tracert command's maximum hops
option to 10. You ping the remote router interface, 191.67.17.2, and it
succeeds. You issue the command tracert -h 10 191.67.17.2, but the tracert
result does not list the router interface's IP address. Which might be a reason

has added routers between your local and remote network.

You are running an active browser session with your employer's Human
Resources intranet web server. You issue the netstat command from your
