What Does D-DS-FN-23 Stand For?

Decoding the Code Piece by Piece

If you have landed on this page, you probably saw "D-DS-FN-23" on a Dell certification list, a job posting, or a training catalog and wondered what the string actually encodes. Dell Technologies builds its Proven Professional exam codes from a predictable pattern, and once you can read the pattern, the code is no longer cryptic.

• D marks the exam as part of Dell's current naming scheme for Dell Technologies Proven Professional certifications.
• DS points to the subject area, in this case data science.
• FN signals the Foundations level, the entry tier of the track rather than an associate-, specialist-, or expert-level exam.
• 23 indicates the 2023 version of the exam.

Read together, D-DS-FN-23 is the 2023 Foundations exam in Dell's data science track. For a broader overview of the credential itself, see our page on what D-DS-FN-23 is, and for alternate phrasings of the same question, D-DS-FN-23 meaning covers the terminology from another angle.

Which D-DS-FN-23 Are We Talking About?

Exam codes are not globally unique across the industry. Other organizations use similar-looking strings, and a search for the code can surface unrelated credentials. Everything on this site refers only to the Dell Technologies exam, governed by Dell Technologies under its Proven Professional program. If you see a certifying body other than Dell, a fee schedule that does not match Dell's voucher pricing, or a domain list that does not include Hadoop, R, or the eight advanced analytics methods, you are looking at something else.

The Name: Data Scientist, Big Data Analytics, Foundations

The long-form name, Dell Data Scientist and Big Data Analytics Foundations 2023, describes the exam in the words Dell originally used for it. Each part tells you something:

• Data Scientist frames the content around the practitioner role, not a single product. The first domain explicitly covers the data scientist's role alongside big data and analytics concepts.
• Big Data Analytics names the technical center of gravity: analyzing data at a scale where conventional tooling struggles, using distributed technologies.
• Foundations tells you the exam establishes baseline competence. It is the entry point into Dell's data science certification path, not an expert-level validation.
• 2023 pins the version of the exam content.

Dell's current catalog lists the same exam code under the shorter title Dell Data Science Foundations. Dell's published transformation details corroborate the longer title and describe the migration from the predecessor exam DEA-7TT2, effective February 3, 2024. So when you see either title, "Data Scientist and Big Data Analytics Foundations" or "Data Science Foundations," attached to D-DS-FN-23, they refer to the same exam. Our dedicated pages on what D-DS-FN-23 stands for and what D-DS-FN-23 means address these naming variations in more depth.

What the Title Promises: The Six Content Areas

A good way to understand what a name stands for is to see what the exam actually tests. The blueprint, published by Dell with approximate question-distribution weights, has six domains:

Notice how the title maps to the weights. "Data Scientist" corresponds to the small role-and-concepts domain at the front. "Big Data Analytics" corresponds to the two heavyweight domains, which together account for 62% of the blueprint. "Foundations" shows up in the lifecycle and initial-analysis domains, where the exam checks that you understand the process before you reach for algorithms. For the full breakdown of each content area, read our complete guide to the six exam domains.

The Technologies Hiding Behind "Big Data Analytics"

The phrase "Big Data Analytics" is not just branding. It signals a specific technology scope. According to the exam's published content, the exact scope includes R, Hadoop and MapReduce, and SQL with MADlib. That combination tells you what kind of data scientist Dell has in mind: someone who can explore and model data in R, process it at scale with the Hadoop ecosystem, and push analytics into the database with in-database SQL libraries.

This is why Domain 5, at 22%, matters so much. Candidates who come from a purely statistical or Python-notebook background are often surprised by how much distributed-computing and tooling content sits in the blueprint. You do not need to be a Hadoop administrator, but you do need to understand what MapReduce does, why it exists, and how in-database analytics differ from pulling data out to analyze it elsewhere.

How the Exam Is Delivered

Now that the name is decoded, here is what sitting for it involves, drawn from Dell's published program details:

• Duration: 90 minutes.
• Languages: English, French, and Japanese.
• Provider: Pearson VUE, with proctored delivery at a test center or online through OnVUE.
• Online requirements: OnVUE requires a passed system test, a matching government photo ID, and a private room without books or notes.
• Scoring: results are computer-scored and provisional pending Dell review.
• Retakes: a 7-day wait after a first failure and 14 days after any later failure.
• Voucher: Pearson's U.S. store lists the general Dell certification voucher at USD 230, expiring 12 months after purchase. Voucher expiry is separate from credential validity.

Dell does not publish the question count, passing score, or pass rate for this exact exam code in the sources we verified, so be skeptical of any site quoting precise figures. We cover what is and is not known on our pages about the passing score and the pass rate, and the full fee picture is in our certification cost breakdown. Scheduling specifics are on the exam dates page.

The Preparation Route Dell Recommends

Dell's stated requirement is simple: have sufficient practical knowledge and skills, through experience and/or recommended training, and then pass D-DS-FN-23. There is no mandatory course gate. For preparation, Dell recommends the Data Science and Big Data Analytics v2 on-demand course (ES732OCMDSBDA) and its companion lab (ES742OCMDSALN). The accompanying textbook is optional.

One clarification worth making: the lab is a learning aid. It does not establish a separately timed practical exam, so D-DS-FN-23 remains a single proctored exam rather than a lab-based assessment. You can review the eligibility picture in our requirements guide and see how the course and lab fit into a plan in our training overview.

Sequencing Your Study by Weight

Because the blueprint is so lopsided toward Domains 4 and 5, the order in which you study matters more than the total hours. Here is a sequence that respects the weights and the way the topics build on each other:

For a fuller plan, including how to pace practice questions, see our D-DS-FN-23 study guide and the condensed cheat sheet for last-minute review. When you are ready to test yourself against realistic questions, our D-DS-FN-23 practice tests are organized by the same six domains.

Who Benefits from This Credential

As a Foundations-level exam, D-DS-FN-23 suits people at the start of a data science path or those moving toward it from adjacent roles: analysts, database professionals, developers, and IT staff who work around analytics platforms. It also appeals to people in Dell-centric environments who want a vendor-recognized baseline in big data analytics concepts and tools.

Whether it is the right investment depends on your goals. We examine the career angle in our jobs page, the earnings question in the salary guide, and the cost-benefit analysis in is the certification worth it. If you are still sizing up the effort, how hard the exam is gives a realistic view. Credential status is tracked in CertTracker, and recognition follows Dell's current requirements, including revised exams when Dell requires them, so check Dell's policies before you plan around a particular version.
