Overview
This exam is a qualifying exam for the Associate - Information Storage and
Management (DCA-ISM) certification.
This exam focuses on information storage and management in a modern data center
environment. It includes technologies driving digital transformation,
intelligent storage systems, software-defined data center, storage networking
technologies, and various business continuity options – along with security and
management of a storage infrastructure. A limited number of questions refer to
product examples that are used in the training to reinforce the knowledge of
technologies and concepts.
Dell Technologies provides free practice tests to assess your knowledge in
preparation for the exam. Practice tests allow you to become familiar with the
topics and question types you will find on the proctored exam. Your results on a
practice test offer one indication of how prepared you are for the proctored
exam and can highlight topics on which you need to study and train further. A
passing score on the practice test does not guarantee a passing score on the
certification exam.

I always enjoy Scott Duffy training videos. I like how this followed the skills
outline from Dell EMC.
It was a great course which helped me to clear DEA-1TT5, I had previous experience
in QnA Maker and Bot services but other major areas are very well covered by
Scott. In the practice test I scored 70% in the first attempt.. but it gave
proper understanding and logic building thrust.
Jessica
This course is a great walkthrough Azure Cognitive Services, but definitely not
prep material for DEA-1TT5 exam.
Scott: cleard my exam in one week
Despite being recently updated this course feels out of date, for example there
are 31 minutes of videos on QnA maker, but this service does not appear on the
current study guide and its not clear from the course content how this differs
from its replacement (Azure Cognitive Service for Language).
Furthermore, 10 minutes of videos on knowledge mining feels low for an area that
makes up 15-20% of the exam
