Dell EMC PowerScale Solutions Specialist for Technology Architects certificate exam i have cleared friends with 79%. My friends, i suggest to take practice tests also for this. This is very helpful.
The mock tests on edusum are online. I did premium DES-1423 practice tests whenever i had time. This helped me cover the syllabus and also pay attention to my current job. The Dell EMC PowerScale Specialist for Implementation Engineers questions on the test simulators were quite challenging and they gave me enough practice for Dell EMC PowerScale Specialist certification exam.
