1 Which switching mode describes a switch that transfers a frame as soon as the destination MAC address is read? fragment-free * cut-through store-and-forward latency forwarding 2 What does a switch broadcast to let other switches know of its existence on the LAN? STP STA BDPU BPU * BPDU 3 Which of the following network types uses networking devices to extend the distances that cable can be run? length/shared media * extended shared media point-to-point network extended point-to-point network multiple access/point-to-point 4 Which of the following is a term associated with replacing hubs with switches to increase the number of collision domains? encapsulation latency * segmentation layered model broadcast domain extended 5 While working on her computer, Mary noticed longer than normal network data transfers. Mary investigates the problem and notices that her co-worker John has been hosting an online video conference. What is the network probably experiencing? collision storm * broadcast storm IP storm data rain storm 6 Which of the following does a router use to make a forwarding decision? * destination IP address MAC address source IP address encapsulation address default gateway 7 A network administrator has a multi-floor LAN to monitor and maintain. Through careful monitoring, the administrator has noticed a large amount of broadcast traffic slowing the network. Which device would you use to best solve this problem? bridge hub * router transceiver 8 What is a disadvantage of cut-through switching? * no error checking a decrease in error checking decrease in number of collision domains decrease in bandwidth increased latency 9 Which of the following would alleviate the problem of excessive collisions in a LAN? (Choose two.) * reduce the size of collision domains reduce number of broadcast domains add extra hubs * add extra managed switches add additional transceivers increase the length of UTP cable runs 10 Which of the following protocols is used to eliminate loops? * STP BDPU UDP EIGRP learning 11 Which of the following are considered Layer 1 devices? (Choose two.) router switch * repeater bridge * hub 12 Which of the following are not to be exceeded when implementing the 5-4-3-2-1 Rule? (Choose three.) five broadcast domains * four hubs three routers * three host segments * one collision domain 13 Which of the following describes the concept of full-duplex mode? traffic passing in one direction at a time with no collisions traffic passing faster downstream than upstream * traffic passing equally in both directions with no collisions traffic passing faster upstream than downstream 14 Which switching mode results in the lowest amount of latency and provides no error checking? * cut-through fragment-free store-and-forward synchronous 15 What impact does a bridge have on a network? (Choose two.) reduces the number collision domains * increases number of collision domains adds additional broadcast domains * has no impact on broadcast domains reduces the length of the shared media 16 Which items are contributors to latency in a switched network? (Choose two.) * circuit delays * software delays incorrect MAC addressing too many collision domains 17 Which LAN devices make frame forwarding decisions based on MAC addresses? (Choose two.) hub router * bridge * switch transceiver 18 What does a switch build as it reads MAC addresses that pass through it? Routing Topology table * Content Addressable Memory table Store and Forward list Cut-through domain MAC Route Address table 19 What will a bridge do if it receives a frame with a MAC address that is not within the table? discard frame ignore frame send frame to appropriate port * send frame to all ports except source port 20 A switch reads the first 64 bytes of a data field and forwards data, before the entire data field has been read. Which switching method allows this? store and forward cut-through * fragment-free asymmetric symmetric 21 Which switching method allows a switch to receive the entire frame before sending it out the destination port? * store and forward cut-through fragment-free asymmetric 22 What does a workstation broadcast to learn an unknown MAC address? RARP request * ARP request STA request STP request 23 Which LAN switching mode has the lowest latency? * cut-through fragment-free latency forwarding store-and-forward
