(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: Routers, switches, and bridges don’t transmit broadcasts. They segment a large cumbersome network, into multiple efficient networks. 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 NO: 2 Routers perform which of the following functions? (Select three) A. Packet switching B. Collision prevention on a LAN segment. 640 - 801 Leading the way in IT testing and certification tools, www.testking.com - 5 - 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 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 NO: 3 The Sales and Production networks are separated by a router as shown in the diagram below: 640 - 801 Leading the way in IT testing and certification tools, www.testking.com - 6 - 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. 640 - 801 Leading the way in IT testing and certification tools, www.testking.com - 7 - C. Since the network size is effectively cut into half, the number of collisions should decrease dramatically. E. Broadcasts from one segment will be completely hidden from the other segment. QUESTION NO: 5 Which of the following are benefits of segmenting a network with a router? (Select all that apply) A. Broadcasts are not forwarded across the router. B. All broadcasts are completely eliminated. C. Adding a router to the network decreases latency. D. Filtering can occur based on Layer 3 information. E. Routers are more efficient than switches and will process the data more quickly. F. None of the above. Answer: A, D Explanation Routers do not forward broadcast messages and therefore breaks up a broadcast domain. In addition, routers can be used to filter network information with the use of access lists. Incorrect Answers: B. Broadcasts will still be present on the LAN segments. They will be reduced, because routers will block broadcasts from one network to the other. C. Adding routers, or hops, to any network will actually increase the latency. E. The switching process is faster than the routing process. Since routers must do a layer 3 destination based lookup in order to reach destinations, they will process data more slowly than switches. QUESTION NO: 6 The Testking Texas branch network is displayed in the following diagram: 640 - 801 Leading the way in IT testing and certification tools, www.testking.com - 8 - Of the following choices, which IP address should be assigned to the PC host? A. 192.168.5.5 B. 192.168.5.32 C. 192.168.5.40 D. 192.168.5.63 E. 192.168.5.75 Answer: C. Explanation: The subnet mask used on this Ethernet segment is /27, which translates to 255.255.255.224. Valid hosts on the 192.168.5.33/27 subnet are 192.168.5.33- 192.168.5.62, with 192.168.5.32 used as the network IP address and 192.168.5.63 used as the broadcast IP address. Therefore, only choice C falls within the usable IP range. QUESTION NO: 7 The Testking.com network is displayed in the diagram below: 640 - 801 Leading the way in IT testing and certification tools, www.testking.com - 9 - Based on the diagram above, how many collision domains are present in the TestKing.com network?? A. One B. Two C. Three D. Four E. Five F. Six G. Fourteen Answer: B Explanation: Since hubs are being used for both Ethernet segments, there are a total of two collision domains. Routers do not forward broadcast and are used to segment LANs, so TestKingA consists of one collision domain while TestKingB consists of the second collision domain. QUESTION NO: 8 Network topology exhibit [...]... The IP network 210.106.14.0 is subnetted using a /24 mask How many usable networks and host addresses can be obtained from this? A B C D E 1 network with 254 hosts 4 networks with 128 hosts 2 networks with 24 hosts 6 networks with 64 hosts 8 networks with 36 hosts Answer: A Explanation: A subnet with 24 bits on would be 255.255.255.0 Since this is a class C network, this subnet can have only 1 network. .. class B network, then the remaining 7 bits are used for the number of networks Again using the 2n-2 formula, we have 2n-2 = 126 networks that are available Incorrect Answers: A This will provide for only 1 network with 216-2 = 65534 hosts B This will provide for 6 networks with 8190 host addresses D This will provide 254 networks and 254 hosts E This will provide 2046 different networks, but each network. .. result of a /26 network mask B This would be the result of a /27 network mask C Remember we need to always subtract two for the network and broadcast addresses, so this answer is incorrect D This would be the result of a /30 network mask QUESTION NO: 26 The 201.145.32.0 network is subnetted using a /26 mask How many networks and IP hosts per network exists using this subnet mask? A B C D E 4 networks with... subnet mask? A B C D E 4 networks with 64 hosts 64 networks and 4 hosts 2 networks and 62 hosts 62 networks and 2 hosts 6 network and 30 hosts Answer: C Explanation: A class C network with a 26 bit mask requires 2 bits for the network address, leaving 6 bits for host addresses Using the 2n-2 formula (22-2 for the network and 26-2 for hosts) we have 2 network addresses and 62 host addresses Incorrect... means the network mask is 255.255.255.252, and the 192.168.24.59 address is the broadcast address for the 192.168.24.56/30 network D This is the all 1’s broadcast MAC address E This is a multicast IP address QUESTION NO: 12 How many subnetworks and hosts are available per subnet if you apply a /28 mask to the 210.10.2.0 class C network?
