CompTIA DataX Certification Exam Sample Questions (Q22-Q27):

NEW QUESTION # 22
A data analyst wants to generate the most data using tables from a database. Which of the following is the best way to accomplish this objective?

  • A. RIGHT OUTER JOIN
  • B. INNER JOIN
  • C. FULL OUTER JOIN
  • D. LEFT OUTER JOIN

Answer: C

Explanation:
# FULL OUTER JOIN returns all rows from both tables, inserting NULLs where no match exists. This join includes the maximum possible number of records - all matches, plus all unmatched records from both sides.
Why the other options are incorrect:
* A: INNER JOIN returns only matching rows - less total data.
* B & C: LEFT/RIGHT JOIN include all rows from one table only.
Official References:
* CompTIA DataX (DY0-001) Study Guide - Section 5.2:"A FULL OUTER JOIN maximizes data volume by including all matched and unmatched records from both tables."
* SQL for Data Science, Chapter 4:"Use FULL OUTER JOIN when the goal is to preserve every record from both datasets regardless of match."

NEW QUESTION # 23
A data scientist needs to:
Build a predictive model that gives the likelihood that a car will get a flat tire.
Provide a data set of cars that had flat tires and cars that did not.
All the cars in the data set had sensors taking weekly measurements of tire pressure similar to the sensors that will be installed in the cars consumers drive.
Which of the following is the most immediate data concern?

  • A. Insufficient domain expertise
  • B. Lagged observations
  • C. Granularity misalignment
  • D. Multivariate outliers

Answer: C

Explanation:
# Granularity misalignment refers to a mismatch between the level of detail in the predictor variables and the event being predicted.
In this case, flat tires are likely discrete, infrequent events, while tire pressure is measured weekly. If the prediction model is trying to link a specific tire pressure value to a binary outcome (flat tire: yes/no), and the timing doesn't align precisely, the predictor variable (pressure) may not be granular enough to accurately associate with the event.
Why the other options are incorrect:
* B: While outliers can exist, they are not the most immediate concern given the time-series nature of the data.
* C: While domain expertise is helpful, it doesn't directly address the data structure issue.
* D: Lagged observations can be engineered in modeling but aren't the primary problem here.
Official References:
* CompTIA DataX (DY0-001) Official Study Guide - Section 3.1 (Data Granularity):"Granularity misalignment occurs when the temporal or spatial resolution of features does not align with the prediction target."
* Data Science Process Guide, Section 2.3:"Predictive performance can suffer when temporal mismatch exists between observations and outcomes. Granularity issues must be resolved prior to modeling."

NEW QUESTION # 24
Which of the following layer sets includes the minimum three layers required to constitute an artificial neural network?

  • A. An input layer, a dropout layer, and a hidden layer
  • B. An input layer, a convolutional layer, and a hidden layer
  • C. An input layer, a hidden layer, and an output layer
  • D. An input layer, a pooling layer, and an output layer

Answer: C

Explanation:
# A basic artificial neural network (ANN) consists of:
* An input layer to receive data
* At least one hidden layer to process the data
* An output layer to produce predictions
These three layers form the minimal architecture required for learning and transformation.
Why the other options are incorrect:
* A: Pooling layers are used in CNNs, not core ANN structure.
* B: Convolutional layers are specific to CNNs.
* D: Dropout is a regularization technique, not a required component.
Official References:
* CompTIA DataX (DY0-001) Study Guide - Section 4.3:"ANNs must include an input layer, hidden layer(s), and an output layer to form a complete learning structure."
* Deep Learning Fundamentals, Chapter 3:"At a minimum, a neural network includes input, hidden, and output layers to process and propagate data."

NEW QUESTION # 25
Which of the following issues should a data scientist be most concerned about when generating a synthetic data set?

  • A. The data set consuming too many resources
  • B. The data set having insufficient row observations
  • C. The data set having insufficient features
  • D. The data set not being representative of the population

Answer: D

Explanation:
# When generating synthetic data, the key concern is ensuring it accurately reflects the characteristics of the real-world population. A non-representative synthetic dataset may lead to biased models and invalid conclusions.
Why the other options are incorrect:
* A: Resource usage is a technical concern but not as critical as representativeness.
* B: Feature set can often be replicated or engineered - quality matters more.
* C: Synthetic datasets can be scaled up easily - representativeness is harder to validate.
Official References:
* CompTIA DataX (DY0-001) Study Guide - Section 5.4:"Synthetic data must maintain representational fidelity to the original population in order to be useful for modeling or validation."

NEW QUESTION # 26
The term "greedy algorithms" refers to machine-learning algorithms that:

  • A. examine every node of a tree before making a decision.
  • B. apply a theoretical model to the distribution of the data.
  • C. update priors as more data is seen.
  • D. make the locally optimal decision.

Answer: D

Explanation:
# Greedy algorithms make decisions based on what appears to be the best (most optimal) choice at that current moment - i.e., a locally optimal decision - without regard to whether this choice will yield the globally optimal solution.
Examples in machine learning:
* Decision Tree algorithms (e.g., CART) use greedy approaches by selecting the best split at each node based on information gain or Gini index.
Why the other options are incorrect:
* A: This refers to Bayesian updating, not greedy behavior.
* B: That describes exhaustive search, not greediness.
* C: That aligns more with probabilistic or generative models, not greedy strategies.
Official References:
* CompTIA DataX (DY0-001) Official Study Guide - Section 4.2 (Model Selection Methods):"Greedy algorithms make locally optimal decisions at each step. Decision trees, for instance, use greedy splitting based on current best criteria."
* Elements of Statistical Learning, Chapter 9:"Greedy methods make stepwise decisions that maximize immediate gains - they are fast, but may miss the global optimum."
