Certified Data Center Specialist (CDCS)


Certified Data Center Specialist (CDCS®) Training (HK259)

Course Description

The Certified Data Center Specialist course is a three-day
course designed to bring participants to the level of a
suitable sparring partner with suppliers. They will be able to
verify offers provided by vendors for correctness,
effectiveness and efficiency. CDCS® is a must have
certification for professional data center managers and
personnel. CDCS® is a pre-requisite for individuals wishing to
achieve the CDCE® status..

Duration : 3 days

Certification Examination

The exam is a one and a half hour, 60 questions, multiple choice and
closed book exam. The candidate requires a minimum of 45 correct
answers to pass the exam. Attendees passing the exam will be
awarded the internationally accredited and recognized ‘Certified Data
Center Specialist’ certificate (CDCS). The certification is valid for three
years after which the student needs to re-certify.


Participants must hold a valid CDCP® certificate in order to be able to
register for the CDCS® class..
