    2. 
       work patterns in the bank
       
    3. 
       the computers and operating systems to be connected to the network
       
    4.

    2. 
       a DVD/CD-ROM array attached to a server
       
    3. 
       a printer attached to a network computer
       
    4. 
       a network switch
       
12. 
    When you design a network that has a bus or star-bus hybrid design, what organization’s specifications should you check to make sure you follow the bus segment length requirements?
    
    1. 
       Microsoft
       
    2. 
       Red Hat
       
    3. 
       Institute of Electrical and Electronics Engineers
       
    4. 
       National Electrical Contractors Association
       
13. 
    Your organization has a network that uses the star-bus hybrid topology. A new network associate is in the process of ordering spare network parts and has included 20 terminators in the order. Which of the following is your advice?
    
    1. 
       Increase the order, because terminators burn out quickly on busy star-bus networks.
       
    2. 
       Be certain to order terminators that contain LEDs to ensure communications can go only one way on the network.
       
    3. 
       Order 200 ohm terminators, because the network contains over 50 connections requiring a high overall resistance.
       
    4. 
       Omit the portion of the order for terminators, because terminators are built into the devices.
       
14. 
    High-speed WANs that use the ring topology may use which of the following?
    
    1. 
       two loops for redundant data transmission
       
    2. 
       ring connectors that work like terminators
       
    3. 
       baseband optics
       
    4. 
       overflow NICs to regulate the speed of transmission
