Use a CNAME record for a that points to b.

That is not legal. If a name has a CNAME record it may not have any
other data. This includes an SOA and NS records. A domain name must have
SOA and NS records. The only way to do this is to use an A record with
the same value as b.com's A record.

Some nameservers permit this misconfiguration. Don't do it, you will
regret it.

This only applies to the name of the domain itself. There is nothing
wrong with having e.g. www.a.com as a CNAME, as long as it has no other
records.

Could you be more explicit? I have now started to configure a DNS, and
if your intention is redirect one of the hosts under your DNS to other I
think that a solution could be using a CNAME entry in the zone description
file, something like:
A.com. CNAME B.com.

The ending dots are important if you are referring to the full name because
if you dont write them the names would be considered as canonical names and
would be added to the full name:
imagine you have domain.com and the host is A.domain.com ...
A.domain.com ---> would be A.domain.com.domain.com
A.domain.com. ---> would be A.domain.com (your domain domain.com would
not be added)

I hope this helps you
