  1. What is the purpose of having IRQs?
    The Interrupt Request (IRQ) number determines the process that needs to be executed.
  2. What happens when an interrupt occurs?
    The request causes the processor to stop the current process, place it on the stack and call the driver referenced by a vector derived from the IRQ number. The driver then processes the data that generated the IRQ
  3. If there are both legacy and Plug-N-Play NICs on your computer, why is it best to configure the legacy NIC's first?
    Because Plug and Play NICs are able to find available NIC configurable parameters after the legacy NIC parameters are configured
  4. What role does the system BIOS have regarding the operation of Plug-N-Play NICs?
    The BIOS automatically configure Plug and Play NIC parameters so as not to conflict with one another or legacy NICs
  5. Why are the NDIS and ODI specifications so important to network communications?
    These specifications enable multiple media NICs and their drivers to interface with a single protocol stack
  6. What does it mean to bind a protocol stack to a NIC?
    It means using the NDIS or ODI interface to establish the link between the Network Layer software, such as IP, and the driver of the NIC by providing the appropriate addresses in memory.
  7. The IP address of the devices on our network all begin with the three fields 192.192.192. To what class do such network addresses belong?
    These device addresses belong to a Class C network. Class C networks have addresses in which the first field has values in the range 192 to 223.
  8. What is the purpose of having a default gateway?
    If the destination address in a frame is not one on the subnet to which the sender is attached, the default gateway will route the packet according to its routing table
  9. What capability does NBT provide?
    NetBIOS over TCP/IP (NBT) enables NetBIOS traffic that is used on Microsoft Networks sent to a destination not on the Microsoft Network, to be encapsulated in a TCP/IP packet and routed by the default router.
  10. What is the value of creating a Windows NT domain?
    • -Enables sharing of network resources between devices
    • -Server provides security-based control over access to resources on all devices that are member of the domain
    • -Enables the establishment of multiple domains in an organization, maintains current databases of domain members and permissions, and enables single logon to multiple domains
  11. What advantage is provided by having WINS and DNS server process collaborate?
    The DNS database is a static database of URL addresses mapped to IP addresses. Collaboration with the WINS database maintains the currency of the URL device name.
  12. What is the purpose of configuring a Communit Name for the SNMP agent?
    The SNMPv1 Community Name serves as a password for Read or Write access to the values of objects
  13. What is the purpose of an SNMP trap?
    Used to inform a Management Station of events that may required action by the station or the responsible network manager
  14. What is the primary difference between Windows NT 4.0 server and workstation OS?
    There is no difference at the kernel level. The difference is that the Server OS provides security for NT domains and many more services
