Answers
D.

rollover

Suggested answer: D

Explanation:

Rollover cables are specifically designed for connecting to the console ports on Cisco routers and switches. Here's why they are the right choice:

Pinout: Rollover cables have a reversed pinout compared to standard Ethernet cables. This matches the console port's wiring, allowing for configuration access.

Appearance: Rollover cables are often light blue in color to help distinguish them from standard Ethernet cables.

USB Adapter: Many modern laptops may not have a direct serial port. In this case, a rollover cable with a USB-to-serial adapter is used.

Why other options are incorrect:

Straight-through: Used for connecting unlike devices (e.g., switch to computer). They won't have the correct wiring for console connections.

Fiber: Used for high-speed, long-distance networks. Console ports use a serial-based connection, not fiber optics.

Crossover: Used to connect similar devices (e.g., switch to switch). The pinout is not the same as what a console port requires.
