About D-DS-FN-23 Exam
Foundations of the Dell-EMC D-DS-FN-23 Certification
The Dell-EMC D-DS-FN-23 exam is a way for entry-level professionals to show they understand the basics of data science without needing to be deep into coding or advanced math. This exam isn’t about chasing trendy buzzwords. It focuses on real analytical thinking, business applications, and foundational concepts that help teams make smarter decisions using data. It’s for those who want to move beyond dashboards and spreadsheets and start thinking in terms of data flows, modeling logic, and what data can actually say when handled correctly.
What It Aims to Measure and Why It’s Useful
The exam isn’t about catching you off guard. It’s designed to test whether you understand data analysis processes, the logic behind machine learning models, and how all this fits into a business setup. Instead of throwing equations at you, it checks whether you know how analytics works in practical terms. You’ll face multiple-choice questions, with many tied to short case examples. Some will test raw concepts, while others check whether you can connect data decisions to business problems. That’s what makes this cert useful it prepares you for real-world thinking, not just textbook stuff.
The Topics That Actually Show Up
Dell keeps its exam content broad but focused. Here’s what you can expect on exam day: questions that touch everything from statistical basics to machine learning workflows. Many candidates overlook the business context part, which ends up being a mistake. It’s not all theory. You’ll be expected to know how to clean data, what types of charts make sense for specific insights, and how to evaluate model accuracy.
Here’s a quick topic rundown:
- Descriptive, diagnostic, and predictive analytics
- Data cleaning and transformation
- Visualization and presentation methods
- Statistical measurements and probability
- Supervised vs. unsupervised learning
- Model performance metrics like precision, recall, and F1
- Tool exposure: Python basics, SQL logic, and some R mentions

Not Everything in the Syllabus Is Weighted Equally
While all topics mentioned above can appear, Dell tends to focus more on model evaluation, data prep, and business application logic. Topics like Python syntax or advanced math show up less frequently. That doesn’t mean you can ignore them but if you’re short on time, emphasize the areas that carry the most weight. Understanding how to clean, explore, and analyze datasets will help more than memorizing obscure statistics formulas.
Here are some areas that are worth your extra time:
- How to choose the right chart or visualization
- Steps in handling missing data
- Key performance metrics for classification models
- When to use supervised vs. unsupervised learning
- How analytics connects to KPIs or business outcomes
A Common Misstep: Learning in the Wrong Order
One issue that slows candidates down is focusing too much on theory first, hoping it’ll all make sense later. This backfires. What works better is starting with real examples, getting a feel for data workflows, and then plugging in the theory when needed. Dell’s exam questions tend to be situational, so just memorizing definitions won’t cut it. You’ll need to know why a method fits a certain business case and not just how it works on paper.
What Makes This Exam Manageable (and What Doesn’t)
This cert isn’t a hard one if you prepare right. You don’t need a PhD or advanced math. But you do need structure. People who walk in with scattered prep or rely only on one source tend to struggle. Most who succeed spend about 3–4 weeks of consistent, part-time study.
Here’s a sample weekly breakdown for better structure:
Week 1:
- Learn the types of analytics
- Get used to how data is cleaned
- Understand what makes data trustworthy
Week 2:
- Dive into modeling basics
- Compare different ML workflows
- Review statistics used in business analytics
Week 3:
- Practice real exam-style questions
- Review weak areas through topic-based study
- Focus on model evaluation and real case-based logic
Mistakes That End Up Costing Time and Points
Several test-takers fall into common traps not because they’re lazy, but because they misread how practical this exam is.
Here are three big ones:
- Spending too long on memorizing formulas you’ll never need
- Ignoring visualization and communication questions
- Rushing through questions without catching tricky qualifiers in the language
You can avoid most of these by making your study process active instead of passive. That means reviewing wrong answers, questioning explanations, and writing out your own logic before looking at the right one.
