CCNA: Cisco Certified Network Associate — Question 999

Which cable type must be used when connecting a router and switch together using these criteria?

• Pins 1 and 2 are receivers and pins 3 and 6 are transmitters.
• Auto detection MDI-X is unavailable.

Answer options

• A. crossover
• B. rollover
• C. console
• D. straight-through

Correct answer: A

Explanation

A crossover cable is necessary in this scenario because it allows the transmitters and receivers of the two devices to connect correctly. A rollover cable is used for console connections, while a console cable is meant for management access, and a straight-through cable is typically used to connect similar devices, which does not meet the criteria given.
