220-801 · Question #727
A customer would like to upgrade their onboard fast Ethernet connection to connect to their new gigabit network at the gigabit speed. Which of the following will enable them to do so?
The correct answer is B. Install a 10/100/1000 NIC. Onboard Fast Ethernet is physically limited to 100 Mbps; connecting to a gigabit network at full speed requires installing a NIC that supports 1000 Mbps.

Why each option
Onboard Fast Ethernet is physically limited to 100 Mbps; connecting to a gigabit network at full speed requires installing a NIC that supports 1000 Mbps.
Converting to wireless does not reliably deliver gigabit wired speeds and does not satisfy the requirement for a gigabit wired network connection.
A 10/100/1000 NIC (Gigabit Ethernet adapter) contains hardware transceivers capable of autonegotiating to 1000 Mbps, replacing the onboard Fast Ethernet controller's physical speed ceiling of 100 Mbps.
Driver updates can optimize existing controller behavior but cannot alter the physical speed ceiling of a Fast Ethernet chip that lacks gigabit hardware.
Flashing the BIOS cannot enable hardware speed capabilities that are not physically present on the onboard Fast Ethernet controller.
