CompTIA DataX Certification Exam Sample Questions (Q51-Q56):

NEW QUESTION # 51
A data analyst is analyzing data and would like to build conceptual associations. Which of the following is the best way to accomplish this task?

  • A. POS
  • B. NER
  • C. n-grams
  • D. TF-IDF

Answer: C

Explanation:
# n-grams (bigrams, trigrams, etc.) are sequences of N words used to analyze co-occurrences and build conceptual or contextual associations between terms in natural language processing (NLP). This helps in understanding the semantic structure of language and is ideal for finding relationships between words.
Why the other options are incorrect:
* B: NER (Named Entity Recognition) identifies entities like names or dates; it doesn't focus on conceptual associations.
* C: TF-IDF scores term importance relative to documents, not associations.
* D: POS (Part of Speech) tagging identifies word roles (noun, verb, etc.), not direct associations.
Official References:
* CompTIA DataX (DY0-001) Official Study Guide - Section 6.3:"n-gram analysis is useful for discovering common patterns and associations in unstructured text data."
* Natural Language Processing with Python (NLTK Book), Chapter 3:"N-grams help capture collocations and associations between words that often co-occur, essential for understanding context."

NEW QUESTION # 52
Given a logistics problem with multiple constraints (fuel, capacity, speed), which of the following is the most likely optimization technique a data scientist would apply?

  • A. Non-iterative
  • B. Iterative
  • C. Unconstrained
  • D. Constrained

Answer: D

Explanation:
# This is a classic constrained optimization problem: the boats have fuel, volume, and speed constraints. The goal is to maximize box transport within the fixed limits (e.g., fuel). Constrained optimization methods are explicitly designed to handle such problems.
Why other options are incorrect:
* B: Unconstrained methods do not account for fuel or capacity limits - inappropriate.
* C: Most real-world constrained problems require iterative approaches for convergence.
* D: Iterative may be part of solving, but it's not a type of optimization - constrained is the category.
Official References:
* CompTIA DataX (DY0-001) Study Guide - Section 3.4:"Constrained optimization is used when variables must meet certain limitations or bounds."

NEW QUESTION # 53
Which of the following describes the appropriate use case for PCA?

  • A. Classification
  • B. Regression
  • C. Recommendation
  • D. Dimensionality reduction

Answer: D

Explanation:
# Principal Component Analysis (PCA) is an unsupervised technique used to reduce the dimensionality of large datasets by transforming correlated features into a smaller set of uncorrelated components (principal components) while retaining the most variance.
Why the other options are incorrect:
* B: Classification is a predictive modeling task; PCA is not inherently predictive.
* C: Regression models numerical relationships; PCA does not predict outcomes.
* D: Recommendation systems use collaborative or content filtering, not PCA directly.
Official References:
* CompTIA DataX (DY0-001) Study Guide - Section 3.3:"PCA is primarily used for reducing the number of variables while preserving data structure and minimizing information loss."
* Pattern Recognition and Machine Learning, Chapter 12:"PCA identifies principal axes of variation and is widely used in preprocessing for dimensionality reduction."

NEW QUESTION # 54
A company created a very popular collectible card set. Collectors attempt to collect the entire set, but the availability of each card varies, because some cards have higher production volumes than others. The set contains a total of 12 cards. The attributes of the cards are shown.

The data scientist is tasked with designing an initial model iteration to predict whether the animal on the card lives in the sea or on land, given the card's features: Wrapper color, Wrapper shape, and Animal.
Which of the following is the best way to accomplish this task?

  • A. Linear regression
  • B. Decision trees
  • C. Association rules
  • D. ARIMA

Answer: B

Explanation:
# Decision trees are supervised classification models that can be used to predict a categorical target variable (e.
g., Habitat: Land or Sea) based on input features (e.g., Wrapper color, Wrapper shape, Animal type). They are interpretable, require minimal preprocessing, and are ideal for structured categorical data like this.
Why the other options are incorrect:
* A: ARIMA (AutoRegressive Integrated Moving Average) is used for time-series forecasting, not classification.
* B: Linear regression is used for predicting continuous numeric values, not categorical variables like
"Land" or "Sea".
* C: Association rules (like in market basket analysis) are used to discover relationships or co-occurrence among variables, not to build predictive models.
Official References:
* CompTIA DataX (DY0-001) Study Guide - Section 4.1 & 4.2:"Decision trees are powerful classifiers for categorical output variables and allow for interpretable models based on feature splits."
* Machine Learning Textbook, Chapter 6:"Decision trees are ideal for early-stage model prototyping when the output is categorical and the data structure is tabular."


NEW QUESTION # 55
A data scientist is using the following confusion matrix to assess model performance:
Actually Fails
Actually Succeeds
Predicted to Fail
80%
20%
Predicted to Succeed
15%
85%

The model is predicting whether a delivery truck will be able to make 200 scheduled delivery stops.
Every time the model is correct, the company saves 1 hour in planning and scheduling.
Every time the model is wrong, the company loses 4 hours of delivery time.
Which of the following is the net model impact for the company?

  • A. 25 hours lost
  • B. 165 hours saved
  • C. 165 hours lost
  • D. 25 hours saved

Answer: B

Explanation:
First, we assume 100 trucks (or 100 predictions), as the percentages are easiest to scale on a base of 100.
Using the confusion matrix:
* True Positives (Predicted Fail & Actually Fails): 80 trucks - correct # +1 hr each = +80 hrs
* False Positives (Predicted Fail & Actually Succeeds): 20 trucks - incorrect # -4 hrs each = -80 hrs
* False Negatives (Predicted Succeed & Actually Fails): 15 trucks - incorrect # -4 hrs each = -60 hrs
* True Negatives (Predicted Succeed & Actually Succeeds): 85 trucks - correct # +1 hr each = +85 hrs Now calculate net hours:
Total gain: 80 hrs (TP) + 85 hrs (TN) = +165 hrs
Total loss: 80 hrs (FP) + 60 hrs (FN) = -140 hrs
Net Impact: 165 - 140 = +25 hours saved
So the correct answer is:
B : (25 hours saved)
However, based on the table provided (which appears to be normalized as percentages), the values apply to a total of 100 predictions. Let's recalculate carefully and validate.
Breakdown:
* TP = 80% # 80 × +1 hr = +80 hrs
* FP = 20% # 20 × -4 hrs = -80 hrs
* FN = 15% # 15 × -4 hrs = -60 hrs
* TN = 85% # 85 × +1 hr = +85 hrs
Total hours = +80 + 85 - 80 - 60 = +25 hrs
Final answer: B. 25 hours saved
Official References:
* CompTIA DataX (DY0-001) Study Guide - Section 4.3:"Business cost/benefit analysis based on confusion matrix performance is critical for evaluating model ROI."
