Exam Cram Question

Discussion in 'DNS Server' started by Buck Turgidson, May 19, 2010.

  1. I am going through some questions from the Exam Cram book, and ran into this
    one that makes no sense. To me, nothing is required on Server2 because the
    IP address for printer1 does not lie within its scope.

    Can someone tell me what I am missing here?

    Your network consists of a single Active Directory domain. All serveres run
    Windows Server 2003 SP2. The network contains two servers named Server1 and

    Server1 is configured as a DHCP server and has a scope that contains
    addresses through

    You have a reservation for a printer named Printer1. The reservation
    assigned address

    You install DHCP on Server2 and create a scope that contains addresses to

    You need to ensure that Printer1's IP address always remains the same

    What should you create on Server2?

    A) Exclusion range
    B) Reservation
    C) Supercope
    A) User class

    The answer is B:

    When the Printer is looking for an IP address it will Broadcast its

    Both DHCP servers will respond to the request.

    Server1 will respond with the Reservation you've created
    Server2 will respond with an IP address from its lease range

    The Printer will take the first response it receives and use that. That
    means that you won't find the printer if the address came from Server2
    (because the address isn't the one you expect).

    When dealing with a split scope in DHCP it is extremely important that
    you duplicate any reservation information. Both servers must be prepared
    to give a client with a reservation the same address.

    Remember that the client device has no idea what IP address it's
    supposed to use, so the fact that the address you want it to use is
    within the scope on Server1 is not actually relevant.

    Finally, it is quite common to find that Reservations are leased from
    excluded ranges (split scope or not). I do, in part because the reserved
    addresses are used in firewall rules and I like to keep things nice and
