I'm studying for a exam. I'm still a little confused what EXACTLY a canonical vs. host name is.

Basically a CNAME points to a spot and an A record points to an IP.
For example:

This CNAME
CN=MyDocuments,OU=MyOU,DC=XXXX,DC=Org
is presented as
XXXX.org/MyOU/MyDocuments

whereas this A record points to an IP:
www.XXXX.org.           IN   A      216.173.XXX.XXX

What this means is – when a request for information is made to www.XXXX.org , DNS resolves it to 216.173.XXX.XXX and to further refine the request when you request www.XXXX.org/MyOU/MyDocuments the CNAME record point to that server/information.

Hope this helps……

What test are you studying?

MCSE 2000 #216.

Sooooo.

It sounds like a cname is almost like a share, folder, or file name. Only on spot resolved via DNS?  Correct?

Somewhat, it helps to further define the request and is usually used internally. If you create an exchange server and add a mailbox to a user in AD it will also add a CNAME record for routing.
Hope this helps.

216 – the beast – the only one I have seen harder is 220.
Best of luck.
