Ques 1 / 1 pts tion 1 2/46 In the diagram below, Client A is sending a packet to Host 1. As the packet is coming into the Fa 0/0 interface on router R2, what is the source IP address in the pack... et’s header? 10.1.1.1 172.16.1.2 192.16.1.1 10.1.1.2 172.16.1.1 192.16.1.2 Ques 1 / 1 pts tion 2 Which destination address is used in an ARP request frame? 0.0.0.0 255.255.255.255 3/46 FFFF.FFFF.FFFF 127.0.0.1 01-00-5E-00-AA-23 Q 1 / 1 pts uestion 3 Consider the following topology. Client F has just booted up, and its MAC address has not been learned by switch SW1 (as seen in the output of the show mac address-table command). If Client A sends a frame destined for Client F’s MAC address, what will switch SW1 do with the frame? 10/9/2020 Mid-Term Exam: Part A - Theory (10%): IFT 166: Intro to Internet Networking (2020 Fall - A) 4/46 SW1 will flood the frame out of all of its ports. SW1 will flood the frame out of all of its ports, other than the port on which the frame was received. SW1 will drop the frame, because there is no entry for the destination MAC address in switch SW1’s MAC address table. SW1 will forward the frame out of port Gi 1/0/2 only. No answer text provided. Ques 0 / 1 pts tion 4 Incorrect The image shows two PCs connected together by a crossover UTP cable. Next to each PC is a table showing the operating mode it is capable of. When both are set to autonegotiation, which mode will they operate in? 10 Mbps half-duplex 10 Mbps full-duplex 100 Mbps half-duplex 10 Mbps Full-duplex That's not correct Ques 1 / 1 pts tion 5 Why are two strands of fiber used for a single fiber optic connection? The two strands allow the data to travel for longer distances without degrading. They prevent crosstalk from causing interference on the connection. They increase the speed at which the data can travel. They allow for full-duplex connectivity. Ques 1 / 1 pts tion 6 Which of the following is true of an Ethernet hub? It reads the MAC address of each incoming frame to determine where to sent it. It reads a signal coming in from one port and repeats the signal out to the other ports. It reduces the collisions on an Ethernet network. It sends the same signal back down the port that originally sent it. 7/46 Good work Ques 1 / 1 pts tion 7 Which two causes of networking problems are related to the physical layer? (Select Two) Disconnected cables Improper operation of cooling fans Incorrect MAC address Incorrect default gateway Incorrect subnet mask Good work Ques 1 / 1 pts tion 8 rking (2020 Fall - A) 8/46 What is the broadcast address of the network 192.168.18.0 255.255.255.128? 192.168.18.97 192.168.18.127 192.168.18.255 192.168..255.255 Ques 1 / 1 pts tion 9 Refer to the exhibit. Host A needs to communicate with host D, but host A does not have the MAC address for its default gateway. Which network hosts will receive the ARP request sent by host A? 9/46 only host D only router R1 only hosts A, B, and C only hosts A, B, C, and D only hosts B and C only hosts B, C, and router R1 Ques 1 / 1 pts tion 10 Which three statements are true about the operation of a full-duplex Ethernet network? The host network card and the switch port must be capable of operating in full-duplex mode. Ethernet hub ports are preconfigured for full-duplex mode. A dedicated switch port is required for each full-duplex node. There are no collisions in full-duplex mode. 10/46 In a full-duplex environment, the host network card must check for the availability of the network media before transmitting. Ques 1 / 1 pts tion 11 What is the recommended maximum length (approx.) for a segment of UTP cable? 500 meters 1km 250 meters 100 meters Good work Ques 1 / 1 pts tion 12 1/46 Which default subnet mask provides the most host bits? 255.0.0.0 255.255.0.0 255.255.255.0 255.255.255.252 Good Stuff Ques 0 / 1 pts tion 13 Incorrect A host has an IP address of 192.168.12.2. Which of the following is the correct command for verifying that the network card can transmit/receive and its TCP/IP stack is functioning properly? Ping 127.0.0.1 Ping 192.168.12.2 Ping the default gateway 2/46 None of the above That's not correct Ques 0 / 1 pts tion 14 Incorrect In the following topology, how many collision domains are represented? 6 13/46 7 8 9 That's not correct Ques 1 / 1 pts tion 15 Exhibited is a portion of ABC Company internetwork. Which of the connections can be full duplex? 14/46 Segments 1 and 2 Segment 2 Segments 3 and 4 Segments 2, 3, and 4 Segments 1, 2, 3, and 4 Good work Ques 0 / 1 pts tion 16 Incorrect Which two statements correctly describe MAC addresses? (Select Two) MAC addresses are used to identify a specific NIC. MAC addresses contain a network number and unique host identification. MAC addresses are physical addresses. MAC addresses are always assigned to network devices by a network administrator. 15/46 MAC addresses are Layer 3 addresses. That's not correct Ques 1 / 1 pts tion 17 What valid host range is the IP address 192.168.93.246/29 a part of? 192.168.93.232 through to 192.168.93.247 192.168.93.241 through to 192.168.93.246 192.168.93.240 through to 192.168.93.247 None of the above Ques 1 / 1 pts tion 18 Which subnet does host 172.28.243.215/25 belong to? 16/46 172.28.243.0 172.28.243.96 172.28.243.128 172.28.243.196 Ques 1 / 1 pts tion 19 What is true concerning physical and logical topologies? The logical topology is always the same as the physical topology. Physical topologies are concerned with how a network transfers frames. Physical topologies display the IP addressing scheme of each network. Logical topologies refer to how a network transfers data between devices. Ques 1 / 1 pts tion 20 17/46 How is a unique MAC address assigned to a network card? A unique address is automatically assigned when the card drivers are installed. It is built into the card when the card is manufactured The network administrator must assign the address A unique address is automatically assigned when you boot up the computer. Good work Ques 1 / 1 pts tion 21 How many subnets and hosts per subnet can you get from the network 192.168.72.0/26? 2 subnets and 128 hosts 4 subnets and 62 hosts 8 subnets and 32 hosts 18/46 16 subnets and 16 hosts Ques 1 / 1 pts tion 22 A basic computer network can be described as: A minimum of five computers linked together A number of laptop computers Two or more computers that are linked together The use of satellites linking computers together Good work Ques 1 / 1 pts tion 23 The layer deals with electrical and specifications of the data connec [Show More]
