5.2 DHCP, Subnets

Which two tasks does the Dynamic Host Configuration Protocol perform?

• Set the IP gateway to be used by the network.

• Sends a message offering an IP address, a subnet mask and a lease duration.

• Assigns and returns an IP address from the default pool.

• Performs host discovery.

• Monitors IP performance.

When a DHCP server is configured, which two IP addresses should never be assignable to hosts? (Choose two)

• network or subnetwork IP address

• broadcast address on the network

• IP address leased to the LAN

• IP address used by the interfaces

• manually assigned address to the clients

How does a DHCP server dynamically assign IP address to host?

• Addresses are allocated after a negotiation between the server and the host to determine the length of the agreement.

• Addresses are assigned for a fixed period of time. At the end of period, a new quest for an address must be made, and another address is then assigned.

• Addresses are leased to host. A host will usually keep the same address by periodically contacting the DHCP sever to renew the lease.

• Addresses are permanently assigned so that the host uses the same address at all times.

Consider the router and the two attached subnets below (A and B). The number of hosts is also shown below. The subnets share the 24 high-order bits of the address space: 192.168.122.0/24

Assign subnet address to the subnet A

What is the broadcast address of subnet A?
