- What does a network address of all zeroes indicate?
- the local network
- What does a network address of all ones indicate?
- all networks
- What does a node address of all zeroes indicate?
- the local machine
- What does a node address of all ones indicate?
- all nodes on a specified network
- How does subnetting reduce the routing table size for internal routers?
- routers only need to know addresses for hosts on their subnets and the network addresses for other subnets, rather than for all hosts
- What does ARP do?
- maps a MAC address to an IP address
- Does authorization prevent all rogue DHCP servers from handing out addresses?
- no- only 2000 DHCP servers will check to see if they are authorized
- Who is allowed to authorize DHCP servers
- only Enterprise Admins
- How does a 2000 DHCP server determine if it is authorized?
- it sends a DHCPINFORM message to AD at startup and periodically afterward
- What two pieces of information are necessary to create a scope?
- a range of IP addresses, and a subnet mask
- How can a subnet mask be changed after creating a scope?
- it can't- the scope must be deleted and recreated
- Why can't DHCP servers on one segment normally service DHCP requests on other segments?
- DHCP requests are broadcasts, which do not cross routers
- What DHCP task can DHCP Administrators not perform?

What permission do DHCP Users have?
Who might be placed in this group? - the ability to view information provided by DHCP servers- 1st level support may be placed in this group

- What is a multicast?
- a data transmission where data is sent once, but recieved by many systems listening to a multicast address
- What are multicasts normally used for?
- streaming media
- What requirement must be met for an application to get a MADCAP address?
- it must support the MADCAP API
- How is the DCHP database backed up?
- stop the DHCP service, copy the DCHP directory, and back up HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DHCPServer
- Can a DHCP scope be extended after creation?
- yes
