ITPEC FE Morning October 2023 Question 31
ITPEC FE Morning October 2023 — Question 31 of 80
Switching Hub (Layer 2 Switch) — forwards frames based on MAC address table.
A Layer 2 switch learns which MAC address is reachable on which port, then forwards frames only to the correct port.
Why not others:
- (a) Fragmentation — a Layer 3 (router) function, not Layer 2
- (b) Dynamic IP allocation — this is DHCP, not a switch feature
- (d) Broadcast to all ports — this describes a hub, not a switch
Key rule: Switch = selective forwarding by MAC; Hub = broadcast to all ports.
