3 ways to enable DHCP functionality on a routed network:
- Include at least one _
server on each _
- Configure an RFC _-compliant router to forward _ _ between subnets
- Configure a _ _ _ on each subnet to forward DHCP messages between subnets

Including a DHCP server on each subnet increases the _ _.

You should configure at least _ DHCP servers per subnet

DHCP Relay Agent
When enabling relay agent functionality, you can also specify _-_ values for a _ count threshold and a _ threshold.

If you have a DHCP server on the local subnet, this number should be high enough so that the local DHCP server responds to client broadcasts before the DHCP relay agent forwards client requests. Then the DHCP relay agent only contacts a _ DHCP server if the _ DHCP server is not available. This mechanism provides for _ _

Routing and Remote Access
You have a single DHCP server, and multiple subnets. You must provide dynamic IP addresses to all computers. To forward DHCP broadcast messages across subnets, you can use an RFC 1542-compliant _
router
You have configured DHCP relay agents on each of your subnets to provide fault tolerance for DHCP. You notice that the local DHCP relay agent is forwarding the client requests to the remote DHCP server even though the local DHCP server is available. What would you do to correct this?
Increase the boot threshold on the relay agent.
