Question if clients use a yum .repo file to access a Local Satellite

I'm working thru an audit for RHEL5/RHEL6 systems in my production environment. I currently run a Red Hat Satellite v5.8.

Question I'm getting asked if there are .repo files that local clients (RHEL 5 VMs/RHEL 6 VMs are using to get their patches. I haven't answered the question because I don't have enough information as this time.

However I believe the RHEL VMs don't use a .repo file, they are using files under /etc/sysconfig/rhn/up2date and
/usr/share/rhn/RHN-ORG-TRUSTED-SSL-CERT

I can show the URL for the server along with the SSL-CERT too.

Am I correct in my thinking?

thanks
