CompTIA DataX Questions 11–15 (page: 4)

Updated On: 10-Feb-2026

The term "greedy algorithms" refers to machine-learning algorithms that:

  1. update priors as more data is seen.
  2. examine even/ node of a tree before making a decision.
  3. apply a theoretical model to the distribution of the data.
  4. make the locally optimal decision.

Answer(s): D

Explanation:

Greedy algorithms build the solution iteratively by choosing at each step the option that appears best at that moment, without reconsidering earlier choices.



A data scientist is deploying a model that needs to be accessed by multiple departments with minimal development effort by the departments.
Which of the following APIs would be best for the data scientist to use?

  1. SOAP
  2. RPC
  3. JSON
  4. REST

Answer(s): D

Explanation:

RESTful APIs use standard HTTP methods and lightweight data formats (typically JSON), making them easy for diverse teams to integrate with minimal effort and without heavy tooling.



Which of the following compute delivery models allows packaging of only critical dependencies while developing a reusable asset?

  1. Thin clients
  2. Containers
  3. Virtual machines
  4. Edge devices

Answer(s): B

Explanation:

Containers encapsulate just the application and its critical dependencies on a lightweight runtime, making the resulting asset portable and reusable without bundling an entire operating system.



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?

  1. n-grams
  2. NER
  3. TF-IDF
  4. POS

Answer(s): A

Explanation:

n-grams capture contiguous sequences of words, revealing which terms co-occur and form meaningful multi-word concepts. By analyzing these frequent word combinations, you directly uncover conceptual associations in the text.



Which of the following belong in a presentation to the senior management team and/or C-suite executives? (Choose two.)

  1. Full literature reviews
  2. Code snippets
  3. Final recommendations
  4. High-level results
  5. Detailed explanations of statistical tests
  6. Security keys and login information

Answer(s): C

Explanation:

Senior leaders need actionable insights and the overarching outcomes, not the implementation details, so you present your key recommendations alongside a summary of results at a high level.
