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.

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: 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 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 NO: 3 Within the TestKing 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. C. There are six broadcast domains in the network. D. There are four collision domains in the network. E. There are five collision domains in the network. F. There are seven collision domains in the network.

Answer: A, F Explanation: In this network we have a hub being used in the Sales department, and a switch being used in the Production department. Based on this, we have two broadcast domains: one for each network being separated by a router. For the collision domains, we have 5 computers and one port for E1 so we have 6 collision domains total because we use a switch in the Production Department so 5 are created there, plus one collision domain for the entire Sales department because a hub is being used.

QUESTION NO: 4 The Testking corporate LAN consists of one large flat network. You decide to segment this LAN into two separate networks with a router. What will be the affect of this change? A. The number of broadcast domains will be decreased. B. It will make the broadcasting of traffic between domains more efficient between segments. C. It will increase the number of collisions. D. It will prevent segment 1's broadcasts from getting to segment 2. E. It will connect segment 1's broadcasts to segment 2.

Answer: D Explanation A router does not forward broadcast traffic. It therefore breaks up a broadcast domain, reducing unnecessary network traffic. Broadcasts from one segment will not be seen on the other segment. Incorrect Answers: A. This will actually increase the number of broadcast domains from one to two. B. All link level traffic from segment one to segment two will now need to be routed between the two interfaces of the router. Although this will reduce the traffic on the LAN links, it does also provide a less efficient transport between the segments. C. Since the network size is effectively cut into ha
