CompTIA DataX Certification Exam Sample Questions (Q15-Q20):NEW QUESTION # 15
A data scientist is merging two tables. Table 1 contains employee IDs and roles. Table 2 contains employee IDs and team assignments. Which of the following is the best technique to combine these data sets?
  • A. left join on Table 1 with Table 2
  • B. right join on Table 1 with Table 2
  • C. inner join between Table 1 and Table 2
  • D. outer join between Table 1 and Table 2
Answer: C
Explanation:
# An inner join returns only those records that have matching keys (employee IDs in this case) in both tables.
Since each table provides a different attribute for the same entity (employee), an inner join is the most efficient and accurate method when focusing on employees present in both tables.
Why the other options are less ideal:
* B & C: Left or right joins would include unmatched data, which may lead to nulls.
* D: An outer join brings in all records from both tables and fills nulls where no matches exist, which may introduce irrelevant or incomplete entries.
Official References:
* CompTIA DataX (DY0-001) Official Study Guide - Section 5.2:"Inner joins are most appropriate when combining datasets with matching keys to retain only relevant, intersecting records."
* SQL for Data Analysts, Chapter 3:"Use inner joins when combining tables on a common key to include only matched data for analysis."

NEW QUESTION # 16
A data scientist has constructed a model that meets the minimum performance requirements specified in the proposal for a prediction project. The data scientist thinks the model's accuracy should be improved, but the proposed deadline is approaching. Which of the following actions should the data scientist take first?
  • A. Consult the key project stakeholder.
  • B. Request additional funding.
  • C. Test additional model specifications.
  • D. Continue collecting data.
Answer: A
Explanation:
# The model already meets the performance goals outlined in the project proposal. However, since the deadline is near and the data scientist is considering further improvements, the correct approach is to:
# Consult the key project stakeholder. This ensures transparency and aligns actions with stakeholder priorities
- whether to proceed with deployment or invest in further model tuning.
Why the other options are incorrect:
* A: Collecting more data requires time and may exceed project scope.
* B: Requesting funding is premature and not justified if performance goals are already met.
* D: Testing new models takes time and may delay delivery - stakeholder input is needed first.
Official References:
* CompTIA DataX (DY0-001) Study Guide - Section 5.1:"Stakeholder engagement is critical in project decision-making, especially when trade-offs exist between quality and timelines."
* CRISP-DM Framework - Evaluation Phase:"Before modifying models that meet objectives, it is essential to consult business stakeholders to align with their expectations."

NEW QUESTION # 17
Which of the following best describes the minimization of the residual term in a ridge linear regression?
  • A. 0
  • B. e²
  • C. e
  • D. |e|
Answer: B
Explanation:
# In ridge regression, the model minimizes the sum of squared residuals (errors), with an added penalty term on the magnitude of coefficients (L2 regularization). The residual component specifically is represented by:
# e² (squared error)
Thus, ridge regression minimizes:
Minimize: #(y# # ##)² + ##(#²)
Why the other options are incorrect:
* A: |e| corresponds to L1 loss (used in Lasso).
* B: e represents the error term itself, not its minimized quantity.
* D: Zero error is ideal but practically unachievable and not the actual loss function being minimized.
Official References:
* CompTIA DataX (DY0-001) Study Guide - Section 1.4:"Ridge regression minimizes the squared error term with an L2 penalty."
* Introduction to Statistical Learning, Chapter 6:"Ridge regression uses squared error loss, which emphasizes larger deviations more heavily than linear loss."

NEW QUESTION # 18
The following graphic shows the results of an unsupervised, machine-learning clustering model:

k is the number of clusters, and n is the processing time required to run the model. Which of the following is the best value of k to optimize both accuracy and processing requirements?
  • A. 0
  • B. 1
  • C. 2
  • D. 3
Answer: C
Explanation:
# The graph represents a classic "elbow curve," which is often used in clustering (e.g., k-means) to help determine the optimal number of clusters. The point where the curve starts to level off (the "elbow") reflects the best trade-off between model accuracy and processing efficiency.
In this graph, the elbow visually occurs around k = 10. Beyond that, the processing time continues to decrease, but the marginal gain in clustering quality (or drop in processing time) diminishes.
Why the other options are incorrect:
* A: k = 2 underfits the data - too few clusters.
* C & D: k = 15 or 20 provides minimal additional benefit in processing but may overcomplicate the model.
Official References:
* CompTIA DataX (DY0-001) Study Guide - Section 4.2:"The elbow method identifies the optimal number of clusters where the rate of improvement drops significantly."

NEW QUESTION # 19
A data scientist is preparing to brief a non-technical audience that is focused on analysis and results. During the modeling process, the data scientist produced the following artifacts:
Which of the following artifacts should the data scientist include in the briefing? (Choose two.)
  • A. Final charts and dashboards
  • B. Model performance statistics (accuracy, precision, recall, F1 score, etc.)
  • C. Model selection, justification, and purpose
  • D. Code documentation
  • E. Data dictionary
  • F. Mathematical descriptions of clustering algorithms included in the selected model
Answer: A,C
Explanation:
# Non-technical business stakeholders value outcome-oriented visuals (charts, dashboards) and the purpose
/justification for the modeling work. These artifacts directly communicate impact without overwhelming technical complexity.
Why the other options are incorrect:
* C & D: Too technical for a non-technical audience.
* E: Useful, but may be too detailed depending on the level of abstraction desired.
* F: Data dictionary is better suited for technical handoff - not executive review.
Official References:
* CompTIA DataX (DY0-001) Study Guide - Section 5.5:"Business-oriented presentations should emphasize clear visualizations, insights, and executive summaries of model goals."
