Configure, verify and troubleshoot DHCP and DNS IOS/SDM

I was looking at the ICND1 Exam topics and it has the following

Configure, verify and troubleshoot DHCP and DNS operation on a router.(including: CLI/SDM)

I read both Odom, CCENT Exam Cram and CBT Nuggets and they only dabble into this a bit. The only references I found is

DHCP:
Configuring it on SDM

Now I understand that configuring it in the IOS is probabaly very easy, but I just want to know because nowhere in my books does it sow the syntax for DHCP commands

DNS

Sh hosts
no ip domain-lookup
ip host 2610A 192.168.2.4

ip domain-lookup
ip name server 192.168.1.1
ip domain-name ccent.com

Am I missing anything?

nope thats pretty much it, you don't even need to create a domain name for your router

nel

im reading from the same book...but dont worry it only goes over it using sdm and not in IOS.

ip dhcp pool test
network 192.168.1.0 255.255.255.0
default-router 192.168.1.1
dns-server 192.168.1.2
domain-name test.com

This is how you configure DHCP in IOS

in your code you may also want to exclude a range of dhcp address from being handed out avoid any conflict with statically assigned ips

Router(config)# ip dhcp excluded-address 192.168.1.1 192.168.1.50
