Question 50/90
You have 10 users plugged into a hub running 10 Mbps half-duplex. There is a server connected to the switch running 10 Mbps half-duplex as well. How much bandwidth does each host have to the server?
Correct Answer: D
When using a hub, all connected devices share the total bandwidth. Since it's a 10 Mbps half-duplex hub, all
10 users share the same collision domain and 10 Mbps. However, when calculating potential access to the server from any single host, each host can use the full 10 Mbps - as long as no other users are transmitting simultaneously.
More importantly, the connection to the server is also 10 Mbps half-duplex, so regardless of the internal collisions, each client could use the full 10 Mbps to the server - just not concurrently with others.
Cisco CCNA Curriculum - Hubs and Bandwidth Sharing:
"In a hub, all ports share bandwidth. However, each host is capable of utilizing the full bandwidth if no contention exists." Rene Meneses MTCNA Study Guide - Hub Limitations:
"A hub provides shared bandwidth, but each device can use the full rate momentarily, assuming no collisions." Hence, the correct answer is based on potential - not divided bandwidth.
