Hi,

I am preparing for the E20-001 exam. My company had purchased the Symmetrix training bundle for me so this entitled me to the 4 ISM E-learning modules and associated study guides. There appears to be missing pertinent learning material from the study guide from ISM1 module. "The structure of cache" section is missing. A search in the associated pdf for the phrase "tag RAM" highlights this as it is not found. I have seen practice questions on the structure of cache (which is how I came upon this) so thought I would highlight this as I thought the 4 modules would provide full coverage. 

Kind Regards,

Victor Forde
