Questions and Answers
  • 1. 
    Which of the following is an advantage to using star topology networks over using bus or ring topology networks?
    • A. 

      Star topology networks are more scalable.

    • B. 

      Star topology networks are less expensive to install.

    • C. 

      Star topology networks are easier to install.

    • D. 

      Star topology networks are more secure.

  • 2. 
    What would happen if a node in a star-wired Ethernet network failed?
    • A. 

      Performance over the entire network would suffer slightly.

    • B. 

      Only the failed node would be unable to transmit or receive data.

    • C. 

      Data could no longer be transmitted or received at any point in the network.

    • D. 

      The failed node would broadcast errors to the rest of the network.

  • 3. 
    What is the function of a hub in a star-wired network?
    • A. 

      To reduce RF emissions that may result in security breaches.

    • B. 

      To increase available bandwidth by sending multiplexed signals.

    • C. 

      To arbitrade addressing conflicts between sending nodes.

    • D. 

      To repeat signals to all nodes on the segment

  • 4. 
    In a network using the star topology, five workstations and a hub would be connected via how many physical cables?
    • A. 

      Three

    • B. 

      Four

    • C. 

      Five

    • D. 

      Six

  • 5. 
    In which of the following networks would it make the most sense to implement a star topology? (Choose all that apply)
    • A. 

      A home network that connects two computers

    • B. 

      A WAN that connects freelance writers across the nation

    • C. 

      A LAN that connects a dozen computers in an insurance company

    • D. 

      A WAN that connects multiple churches within a city

  • 6. 
    What would happen to a star network if one of its workgroup hubs failed?
    • A. 

      All nodes connected to that hub would be unable to communicate with nodes on other segments, but they could communicate with each other.

    • B. 

      All nodes connected to that hub would be unable to communicate with nodes on other segments as well as nodes on their own segment.

    • C. 

      Nodes would be able to communicate with the network, as they would automatically connect to an alternate hub on the backbone.

    • D. 

      Communication on the entire LAN would halt.

  • 7. 
    What type of terminator is used on a star-wired network?
    • A. 

      20-ohm resistor

    • B. 

      50-ohm resistor

    • C. 

      100-ohm resistor

    • D. 

      Terminators are not used on star-wired networks
