What it is
GregLab Exam Prep opens with a marketing and lane-chooser home page, then gives each certification its own study home, topic library, references, practice questions, and readiness context.
The seven AWS lanes cover AWS Certified AI Practitioner (AIF-C01), AWS Certified Cloud Practitioner (CLF-C02), AWS Certified Solutions Architect - Associate (SAA-C03), AWS Certified Developer - Associate (DVA-C02), AWS Certified CloudOps Engineer - Associate (SOA-C03), AWS Certified Data Engineer - Associate (DEA-C01), and AWS Certified Generative AI Developer - Professional (AIP-C01).
The five Microsoft lanes cover Microsoft 365 Copilot and Agent Administration Fundamentals (AB-900), Microsoft Certified: AI Business Professional (AB-730), Microsoft Certified: Azure Fundamentals (AZ-900), Microsoft Certified: Azure Administrator Associate (AZ-104), and Microsoft Certified: Azure Solutions Architect Expert (AZ-305).
Lane pages use durable paths such as /aif-c01/, with individual topics at /aif-c01/topic/<slug>. Learners can change their selected lane from the profile page without mixing content or progress between certifications.
Anonymous study keeps local progress available without an account. Optional Google sign-in can preserve quiz history across devices, while PostgreSQL stores the associated study events.
The production site moved to examprep.greglab.net on August 14, 2026. The former aif-c01.greglab.net host permanently redirects to the new host while preserving paths.
