About DataCertLab

DataCertLab writes study material for data and cloud certifications: free study notes on this site and on GitHub, and practice tests on Udemy.

How the material is made

• Built from the exam guide. Every exam starts from the vendor's published exam guide or skills outline. The notes follow its domains and objectives, and they are updated when the exam changes.
• Official documentation is the source of truth. AI helps with structure and finding gaps. Every technical claim is checked against the vendor's documentation and reviewed by a human.
• Explanations, not answer keys. The notes explain why an option is right and why the look-alike is wrong. Every practice question comes with a full explanation for each option.
