I'm planning to start a data center network design training, These are the most relevant courses to design i found, but not sure which one is the best as high level or for presales engineers
DCFNDU
DCCOR
DCID
Also, i couldn't find any materials or self-study eBooks for those courses, only eLearning is available, but if this is correct, it will be difficult later on to refer to specific or search for any info.
please share your experience.
