Technically, it can occur at either or both locations. However, from a business
and operational point-of-view, most PKIs do the verification at the RA. This is
because it allows different RA's to use different policies, procedures and tools
to do the key-generation, verification, etc., before sending the verified CSR to
the CA for signing.
From an operational point of view, having RAs do the verification
allows you to
scale a CA to sign more certificates in a given unit of time if it
only had to
sign certificates and CRLs instead of verifying and signing.
Yes, the CA can indeed add all the required constraints/extensions as needed to
the certificate based on the profile, before it signs the CSR.
