A school is planning to expand its network to accommodate new classrooms and administrative offices. The existing network infrastructure is based on the $100$BASE$-$TX Fast Ethernet standard with a combination of hubs and switches, utilizing both UTP$-$based horizontal links and fiber optic backbones.

The expansion will require the addition of $50$ new workstations, which will be distributed across various locations within the school, some of which are $90$ meters away from the nearest network device.

The IT team is considering the best approach to integrate these new workstations into the existing network while ensuring optimal performance and compatibility with potential future upgrades.

What should the IT team prioritize to ensure the successful integration of the new workstations into the existing $100$BASE$-$TX Fast Ethernet network in the MOST effective way?

Use fiber optic cables for all new horizontal links.

Extend the fiber optic backbone to each new workstation.

Implement autonegotiation on all network devices.

Replace all existing hubs with switches to reduce collision domains.
