Topic 1: PLANNING & DESIGN (130 questions)
Section 1: Design a simple LAN using Cisco Technology (15 questions)

QUESTION NO: 1

Which of the following devices can an administrator use to segment their LAN?(Choose all that apply)
A. Hubs
B. Repeaters
C. Switches
D. Bridges
E. Routers
F. Media Converters
G. All of the above

Answer: C, D, E

Explanation:

Switches and bridges forward broadcast but router do not forward broadcast.
Switches, bridges and routers can segment an Ethernet collision domain.

Incorrect Answers:

A. Hubs is incorrect because a hub doesn't segment a network, it only allows more hosts on one. Hubs operate at layer one, and is used primarily to physically add more stations to the LAN.
B. This also incorrect because the job of a repeater is to repeat a signal so it can exceed distance limitations. It also operates at layer one and provides no means for logical LAN segmentation.
F. This is incorrect because media converters work by converting data from a different media type to work with the media of a LAN. It also operates at layer one and provides no means for logical LAN segmentation.
