What it validates, who it is written for, and the experience it assumes.
The Dell Data Science Foundations certification (D-DS-FN-23) validates your grasp of the core concepts and practices that underpin modern data analytics. It covers the role of the data scientist, the phases of the data analytics lifecycle, and the statistical and machine-learning methods used to build and evaluate models. You will also learn how to work with big data technologies like Hadoop and MapReduce, and how to communicate findings through effective data visualization.
This certification is part of the Dell Technologies Proven Professional program, which recognizes skills across cloud, infrastructure, and data-centric roles. It is a foundational credential that prepares you for more advanced data science and AI-focused certifications, and it signals to employers that you understand the end-to-end analytics workflow—from raw data to actionable insight.
This certification is intended for systems engineers and technical consultants who work with or support data science and big data analytics initiatives. It is also valuable for IT professionals who need to understand how data analytics projects are structured and executed, even if they are not data scientists themselves. You are likely a good fit if you are comfortable with technical concepts, have some exposure to data or analytics tools, and want to build a foundation in data science terminology, methods, and workflows. No prior data science certification is required.
Dell recommends that candidates complete the recommended training and have some familiarity with data analytics concepts, though no specific experience is mandated. Familiarity with basic statistics and data analysis concepts; Understanding of the data analytics lifecycle and common analytics methods; Exposure to tools like R, Hadoop, or SQL is helpful but not required

In front of every objective the practice pages are already there, free and without an account. This is one objective, opened.
18 questions on this objective, five to a page. Every range above is a real page, open now, with no account.
The curriculum tells you what is on the exam. Proving you know it is a different job — and it is the one the closed-book run does.
The whole bank is open. 5 questions to a page, every answer explained, and a discussion thread on each one.
Every objective, and every page range, is a link — so you can pick up exactly where you left off.
Short enough to finish, long enough to matter.
Not only which one is right — why the others are wrong.
Ask, answer, and vote. Every question has its own thread.
These are not trivia. Each one is written against a concept in the book, so when you get one wrong there is somewhere to go and find out why.

The pages shown here come from our AI-900 book — an example of how each concept is written in plain language and, where the idea needs one, drawn as a full page you can take in at a glance.

The look-alikes sit togetherThe pairs the exam tests are drawn side by side, so the difference is seen, not told.

The sentence to carry into the exam room.
This is the part that teaches. The illustration and the written explanation stay where they are while you work, so a scenario stops being a memory test and becomes something you can simply look at.

Where the exam is defined, scheduled and scored.
We link to them rather than repeat them, so nothing here goes stale behind them.
We build from the official skills outline, not from a summary of it — 27 objectives, 176 concepts written under them, and free questions against every one. When Dell Technologies changes the outline, this page changes with it.
That is the only question worth answering the night before, and no link answers it. You answer it by taking the questions with the book closed, and seeing what comes back.
