Re: Load Balance to set a primary and "backup" server.

That's almost correct. The only problem is, if you have a zone named
a.com, then you can't have a CNAME record named a.com. Instead, you'd
have a CNAME record named www.a.com. (You also can't have a load
balance record named a.com.)

So your CNAME records would look like this:

www.a.com. CNAME www.test.com.
www.b.com. CNAME www.test.com.
www.c.com. CNAME www.test.com.
www.d.com. CNAME www.test.com.
