Question

I need to configure a Cisco router to be the DHCP Server for the 10.10.10.0/24 network. There are a few addresses that are reserved for servers and gateways. The servers are assigned the first 7 addresses of your network and the gateway is using 10.10.10.254. Which of the following commands do I ensure my DHCP server will not assign these addresses to clients?

a) ip dhcp excluded-address 10.10.10.1 10.10.10.7

ip dhcp excluded-address 10.10.10.254

b) dhcp pool exclude 10.10.10.1 - 10.10.10.7

10.10.10.254

c) ip dhcp pool exclude 10.10.10.1 - 10.10.10.7

10.10.10.254

d) ip dhcp excluded-address 10.10.10.0 0.0.0.7

ip dhcp excluded-address 10.10.10.254 0.0.0.0

Answer is A.

Here high address is optional.
