問題文
A small office replaces an old shared hub with a switch. Every workstation keeps the same IP subnet and no router is added. What changes for collision domains and broadcast domains?
選択肢
- Neither changes until a router is added.
- Both the collision domains and the broadcast domains are split per port, so each workstation would end up in a broadcast domain of its own.
- Each switch port becomes its own collision domain, while the broadcast domain stays as one.
- The collision domain stays as one because the switch still repeats every frame to all ports, and the broadcast domain is split per port because each port now has its own forwarding table entry.
