Query optimization is a skill that is very important. However, I do not see the relation of this certificate with an architecture role.
Is there a reason why you think this particular exam fits into architecture?

Thanks for going through my post.
I said that its good to have such certifications for an architect. This certification is focused on tuning and I couldn't find much material on this topic apart from what is provided by Oracle.
