EMCTA & E20-322 help!!!

Hi all!!!

I am on track to complete my EMCTA specifically the "EMC Commercial Storage and Information Infrastructure" track.  I've passed the E20-001 and will be taking the E20-501 tomorrow.  The next and last one after the 501 is the E20-322.  I have the official "Technology Architect Solutions Design Curriculum V3" DVD from EMC that is the prep for the E20-322.  Module 1 covers Symmetrix and Symmetrix related products.  However the E20-322 exam overview (file attached) points out that the following subjects are ONLY covered on the Enterprise variant of the exam:

• Symmetrix: DMX4 with Enginuity 5773 (Enterprise variant of exam only)
• Symmetrix: V-MAX with Enginuity 5874 (Enterprise variant of exam only)
• Solutions Enabler v.6.5 (DMX) , v7.0 (V-MAX) (Enterprise variant of exam only)
• Symmetrix Management Console v6.1 (Enterprise variant of exam only)
• Symmetrix Optimizer V6.0 (Enterprise variant of exam only)
• Open Replicator 6.4 (Enterprise variant of exam only)
• EMC Ionix ControlCenter V6.1 (Enterprise variant of exam only)
• SAN Advisor (Enterprise variant of exam only)
• EMC Ionix Storage Configuration Advisor (SCA) (Enterprise variant of exam only)
• Rainfinity FVA 1.2 (Enterprise variant of exam only)

So my question is can I SAFELY ignore any of the topics listed above in preparation for the E20-322 Commercial exam?  Normally I would have absolutely no problem learning about the additional products however I am under a VERY tight deadline to pass the E20-322 and for my sanity if I can safely exclude these topics the better.

Thanks!!!!
