[Exam Report] Datadog Fundamentals — A Modern Learning Approach Leveraging AI (NotebookLM & Antigravity)
Source: Dev.to
Introduction
With a Datadog implementation planned for an upcoming project, I recently took the Datadog Fundamentals exam to build a solid foundation. As an application engineer with no prior experience in professional monitoring tools, I wanted to see how efficiently I could learn by leveraging modern AI tools. I’m happy to share that I passed!
Exam Results
- Time Taken: 61 minutes (out of 120 minutes total)
- Overall Score: 67.0 / 75
- Result: PASS
I am primarily an Application Engineer, not a dedicated DevOps or Infrastructure specialist. One thing I prioritize for my career growth is taking IT certification exams in English, even though my native language is Japanese. Consuming technical documentation and taking exams in English helps me stay sharp in the global tech landscape.
Baseline Knowledge
- Cloud: AWS Certified Solutions Architect – Professional (and 3 Associates)
- Japanese National Exams:
- Database Specialist: A high‑level national certification for DB design.
- Applied IT Engineer: A comprehensive exam covering CS fundamentals and strategy.
- English: Eiken Grade 1 (CEFR C1/C2 equivalent) and TOEIC 875.
Study Timeline
| Phase | Content | Time |
|---|---|---|
| Input | Official Learning Center (Hands‑on) | ~48.7 h |
| Output | AI‑driven Mock Exams (NotebookLM / Antigravity) | ~14.6 h |
| Total | 63.3 h |
I spent roughly 80 % of my time on hands‑on labs and 20 % on AI‑driven practice. I went through the Datadog Fundamentals Certification Learning Path twice. After the labs, I took the official Practice Exam—a small set of questions that’s crucial for understanding the “vibe” and focus areas of the real test.
Learning Approach
NotebookLM for Accuracy
I fed links to the official Datadog documentation into Google’s NotebookLM.
Why NotebookLM? It uses Source Grounding, meaning it only answers based on the documents you provide. This significantly reduces hallucinations (AI making things up), which is a lifesaver when studying for a technical exam.
Antigravity for Volume
I also used Antigravity (Google’s experimental search/LLM tool) to generate a high volume of practice questions based on the exam scope. It allowed me to “spar” with the AI until the concepts felt like second nature.
In my experience, the AI‑generated questions were very close to the actual exam regarding Datadog‑specific features (Dashboards, Monitors, Logs, etc.). However, there was a slight difference in “foundational IT” questions:
- AI: Tended to ask lower‑layer questions (e.g., specific Linux commands).
- Actual Exam: Focused on higher‑layer conceptual knowledge of systems.
Unofficial Mock Exam
I’ve compiled the questions I generated using AI into a simple web tool for anyone else preparing for the exam. Check it out here:

Reflections
Using AI as a “sparring partner” is a game‑changer for certifications that lack extensive study materials. It allows you to move from passive reading to active recall very quickly.
What about you? Have you used AI to study for certifications? I’d love to hear your workflow in the comments!
