(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 routers do not forward broadcasts by default (they can via the "ip helper-address" command). Switches, bridges and routers can segment an Ethernet collision domain via the use of VLAN's 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. QUESTION 2 Routers perform which of the following functions? (Select Three) A. Packet switching B. Collision prevention on a LAN segment. C. Packet filtering D. Broadcast domain enlargement E. Broadcast forwarding F. Internetwork communication Answer: A, C, F Explanation: Actualtests.com - The Power of Knowing 640-801 A. Routers work in Layer 3 of the OSI Model. A major function of the router is to route packets between networks. C. Through the use of access lists, routers can permit and deny traffic using layer 3 and layer 4 packet information. F. The primary purpose of a router is to route traffic between different networks, allowing for internetworking. Incorrect Answers: B. While routers can be used to segment LANs, which will reduce the amount of collisions; it can not prevent all collisions from occurring. As long as there are 2 or more devices on a LAN segment, the possibility of a collision exists, whether a router is used or not. D. The broadcast domain of a LAN is often segmented through the use of a router. This results in reducing the size of the broadcast domain. E. Routers do not forward broadcast traffic. QUESTION 3 Within the Certkiller office, The Sales and Production networks are separated by a router as shown in the diagram below: Which of the following statements most accurately describes the characteristics of the above networks broadcast and collision domains? (Select the two best answer choices) A. There are two broadcast domains in the network. B. There are four broadcast domains in the network....
