I'm trying to find the following certifications so I can study for them and take the exams. There are field tech positions that require them, but they are not showing up in searches on the website.

1 DSP Security and Privacy Foundations
2 Dell EMC Service Basics 2017 (Cert ID: 3237)
3 Dell 1000 Client Foundation 2019 (Auth ID: 3255)

Any assistance with this would be great! Thank you!
