completing the e20-370 exam requirements

Hi,

Could someone please help me out with the codes for these exams in order to complete Implementation Engineer, Content Addressed Storage certification.

It says I have to complete one of these:

Associate 2004 - EMC Technology Foundations  
Associate 2005 - EMC Technology Foundations (EMCPA)
  
EMC Technology Foundations (EMCPA) 
EMC Technology Foundations - CAS (EMCPA) 
Storage Technology Foundations (Information Storage and Management) (EMCPA)

and this one:

(E20-370)   Content Addressed Storage (CAS) Implementation Exam - I have already passed this exam.

However I need to pass one of the foundation exams and cannot find codes for it.

Thanks
