examlab .net The most efficient path to the most valuable certifications.

About examlab

examlab.net is independent, solo-maintained, and ad-free.

Why this exists

It started after paying too much for cert prep that was either ad-walls, leaked-question dumps, or recycled 2019 videos. The market for cloud and AI cert preparation is broken: most resources optimize for SEO ranking or upsell, not for the candidate actually understanding the material.

I wanted notes I'd actually want to read — so I wrote them. Then I wrote the practice questions. Then I translated everything into Traditional Chinese.

I've passed 8 certifications myself, so I know what candidates actually need during cert prep — and what they don't. That experience shapes every topic write-up on the site: where to go deep, where to stay brief, and which trap patterns deserve to be called out instead of glossed over.

What's on the site

As of May 2026:

  • 12 certifications across two vendors: AWS (CLF-C02, AIF-C01, SAA-C03, DVA-C02, SOA-C02, SAP-C02, DOP-C02, DEA-C01, MLA-C01, SCS-C02, ANS-C01) + Anthropic (CCA-F)
  • 275 long-form topic write-ups, each rebuilt from the official exam guide
  • 8,400+ scenario-style practice questions, each with a worked rationale
  • Full English + Traditional Chinese, parallel — analogies localized for Taiwan readers when relevant

The model

  • CC BY-NC 4.0: free for individuals to use, share, and adapt non-commercially. Want to use it commercially? Open an issue.
  • No ads. No banner, no display, no native, no sponsored content.
  • No signup. No email capture, no "create a free account to continue."
  • No paywall. Practice questions, mock exams, all topics — every byte free to read.
  • Open editorial. Source-of-truth for every topic is the official exam guide; references are linked at the bottom of every page.

Suggest the next certification

The next cert on the roadmap is decided by reader signal. When you tip on Ko-fi, the form has a "Leave a message" field — drop the cert code you want covered next. Examples:

  • Microsoft Azure AZ-104 / AZ-204
  • Google Cloud PCA / ACE
  • Kubernetes CKA / CKAD / CKS
  • HashiCorp Terraform Associate
  • Snowflake SnowPro Core
  • Databricks Data Engineer Associate

The most-requested cert in each batch wins the next slot.
