Brandy is a Linux administrator. She learns from a user that it takes unusually long time
to receive response from another host system. Which command can Brandy execute to
discover how many hops exist form the users system to the target host system?

A.
Tracert.

B.
Router.

C.
Ifconfig.

D.
Chmod.

Explanation:
The tracert (trace route) command is used to learn the number of
hops between systems. Tracert is similar to the ping command, and also uses ICMP.
By limiting the ICMP command, hops can be identified one by one. When this
learning is complete, you will have a map of the hops between the machine issuing
the tarcert and the target of the tracert command.
Incorrect Answers:
B: Router is not a known command.
C: Ifconfig is used on some systems to configure an interface. It does not providerealtime
information that would help map out the network topology to determine hops.
D: chmod changes the permissions on files. It is not used in networking, and cannot beused to
determine network topology, including node hops.
