You want to implement a mechanism that automates the IP configuration, including IP address, subnet mask, default gateway, and DNS information. Which protocol will you use to accomplish this?

A:

SMTP

B:

SNMP

C:

Which of the following describe the DHCP Discover message?

It uses FF:FF:FF:FF:FF:FF as a layer 2 broadcast.
It uses UDP as the Transport layer protocol.
It uses TCP as the Transport layer protocol.
It does not use a layer 2 destination address.

A:

1 only

B:

1 and 2

C:

3 and 4

D:

4 only

Answer: B

A client that sends out a DHCP Discover message in order to receive an IP address sends out a broadcast at both layer 2 and layer 3. The layer 2 broadcast is all Fs in hex, or FF:FF:FF:FF:FF:FF. The layer 3 broadcast is 255.255.255.255, which means all networks and all hosts. DHCP is connectionless, which means it uses User Datagram Protocol (UDP) at the Transport layer, also called the Host-to-Host layer.
