Trouble accessing Practice Exam on AWS for HDPCA

[#1]

I am preparing for HDPCA Exam and while searching for some objectives on Hortonworks Community I found below link for Practice Exam on AWS.

(http://2xbbhjxc6wk3v21p62t8n4d4.wpengine.netdna-cdn.com/wp-content/uploads/2015/04/HDPCA-PracticeExamGuide.pdf)

In the document it ask me to create a AWS account and under EC2 dashboard I may find "Hortonworks HDPCA_x.x PracticeExam_vx" under Community AMIs. However, I do not see any such option and it only give me one option as "HortonworksPre - ami-376c4352".

Is there any alternative for Practice Exam on AWS?

Found it. It isn't available in all Zones. I found it in US East (N Virginia).
