FC0-U71 Practice Question: A small business wants to connect its computers…
A small business wants to connect its computers to share files and printers. Which of the following network devices would BEST facilitate this?
⚠ Common exam trap
Many exam-takers confuse a switch with a hub, assuming both simply 'connect' devices, but the exam tests the understanding that a switch provides intelligent, collision-free forwarding at Layer 2, while a hub is a dumb repeater that degrades performance in a LAN.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Switch
A switch operates at Layer 2 of the OSI model and uses MAC addresses to forward frames only to the specific port where the destination device is connected. This creates a dedicated, collision-free path between the computers, making it the ideal device for connecting multiple computers within a local area network (LAN) to share files and printers efficiently.
