You have a laptop with a free serial port. Which of the following is/are necessary to establish a connection to the console port on a Cisco device?

A. A terminal emulator application

B. A straight-through cable

C. A crossover cable

D. A rollover cable

E. A DB-9 connector

Solution

A, D, and E are correct. To use the console port, attach the DB-9 connector to the serial port of the laptop, and then connect a rollover cable between the console port and the DB-9 connector. A terminal emulator application is needed to send configuration commands.

B and C are incorrect. These are the wrong cable types.
