  1. 1CSMA/CD stands for Carrier Sense Multiple Access with Collision detection, and is used by Ethernet.
    1. AVerdadeiro
    2. BFalso
  2. 2What are the three steps of the Backoff Algorithm?
    1. AA jam signal is sent
    2. BA jam session is started
    3. CAll hosts briefly stop transmitting
    4. DHosts continue to transmit until the packets get through
    5. EHosts run the Backoff Algorithm which calculates a random time before the host can transmit again
    6. FOnly hosts involved in the collision run the Backoff Algorithm
  3. 3Which cabling allows full-duplex?
    1. ATwisted pair cabling with at least four conductors
    2. BCoaxial cabling
    3. CEthernet CAT 5 cabling
    4. DEthernet CAT 6e cabling
  4. 4What is a switch with one host connected to each of its ports called?
    1. AMicrosegmented
    2. BOrganised
    3. CMessy
    4. DDistributed
  5. 5What are the four WAN technologies?
    1. ADedicated Leased Line
    2. BCell switched
    3. CPacket switched
    4. DCircuit switched
    5. EPhone based
    6. FVPN connections
  6. 6Dedicated leased lines are single customer purchased lines that go directly to the building, there are many collisions in these networks.
    1. AVerdadeiro
    2. BFalso
  7. 7What are some disadvantages of dedicated leased lines?
    1. AExpensive when configuring for multiple locations
    2. BNot practical for businesses with a large amount of employees
    3. CUses PPP, HDLC, and SLIP which are bad protocols
  8. 8What are some disadvantages of cell-switched technologies?
    1. AWhen a call is being made with a phone, connecting to the internet is much slower
    2. BUses ISDN or analog dialup
    3. CUses PPP, HDLC, and sometimes SLIP which are all difficult protocols
    4. DTraffic is typically extremely slow because of the singular connections related to the call
  9. 9What are some disadvantages of packet switched connections?
    1. ALike how a PC connects to a hub, all traffic is affected by everyone else's traffic
    2. BUses Frame Relay and X.25
    3. CAllows you to establish virtual connections around the world
  10. 10In cell switched connections, the units are called "cells" which are of a constant size, unlike the packets in a packet switched connection, which makes managing large amounts of data easier and more efficient.
    1. AVerdadeiro
    2. BFalso
