Nice work on AI‑900 — congrats, Aleeyyy. Short answer: choose the next cert based on what you want to do day‑to‑day.
Recommendation (decision rule)
- Want to build and ship AI features inside apps (Cognitive Services, Azure OpenAI, bots, RAG, deploy endpoints)? Go AI‑102 (Azure AI Engineer).
- Want to design, train and tune ML models, run experiments and productionize models (Azure ML/MLOps)? Go DP‑100 (Azure Data Scientist).
- If you feel shaky on core data concepts (databases, ingestion, analytics) first, take DP‑900 (Data Fundamentals) before DP‑100.
Why those picks (brief)
- AI‑102 is application/integration focused — good for developers who must integrate LLMs/CV/NLP into solutions and deploy/manage cognitive services.
- DP‑100 is ML‑centric — good if you want to own model training, evaluation, pipelines and lifecycle.
- DP‑900 is short and intended to cover the data basics so DP‑100 isn’t overwhelming.
Typical timelines & concrete study moves
- AI‑102: ~8–12 weeks if you already code. Follow Microsoft Learn AI‑102 paths and build 2 small projects (example: deploy a Custom Vision container + call it from a web app; build a simple RAG/QnA demo with Azure Search + OpenAI). Use hands‑on sandboxes or free Azure credits.
- DP‑100: ~10–14 weeks. Microsoft Learn + Python ML basics (pandas, scikit‑learn), then train/register/deploy a model in Azure ML and practice metrics, hyperparameter tuning, pipelines.
- DP‑900: ~2–4 weeks. Quick Microsoft Learn modules + light hands‑on with Azure SQL / Cosmos / basic queries.
On practice tests and “dumps”
- Practice exams (MeasureUp, vendor practice tests, well‑made simulators) are useful — but be careful with exam “dumps.” They may violate exam policies and often teach memorization rather than understanding. Use official Microsoft Learn, sandbox labs, and reputable practice assessments alongside hands‑on projects.
If you want a tailored next step, tell me:
1) Your current role / day‑to‑day tasks.
2) Comfort level with Python and ML (none / some / strong).
3) How many hours/week you can study.
With that I’ll recommend a single path (AI‑102 or DP‑100/DP‑900) and give a 6–12 week study plan with weekly tasks and project ideas. Which direction do you prefer — building apps (AI‑102) or building models/data pipelines (DP‑100)?
