NEW QUESTION # 72
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?
Answer: A
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.
NEW QUESTION # 73
A data analyst wants to save a newly analyzed data set to a local storage option. The data set must meet the following requirements:
* Be minimal in size
* Have the ability to be ingested quickly
* Have the associated schema, including data types, stored with it
Which of the following file types is the best to use?
Answer: C
Explanation:
Given the requirements:
* Minimized file size
* Fast ingestion
* Schema preservation (including data types)
The most appropriate format is:
# Parquet - It is a columnar storage file format developed for efficient data processing. Parquet files are compressed, support schema embedding, and enable fast columnar reads, making them ideal for analytical workloads and big data environments.
Why the other options are incorrect:
* A. JSON: Text-heavy and lacks native support for data types/schema.
* C. XML: Verbose and has poor performance in storage and ingestion speed.
* D. CSV: Flat structure, doesn't store data types or schema, and can be large in size.
Official References:
* CompTIA DataX (DY0-001) Official Study Guide - Section 6.2 (Data Storage Formats):"Parquet is a preferred format for data analysis as it provides efficient compression and encoding with embedded schema information, making it ideal for minimal storage and fast ingestion."
* Apache Parquet Documentation:"Parquet is designed for efficient data storage and retrieval. It includes schema support and works best for analytics use cases." Parquet is a columnar storage format that automatically includes schema (data types), uses efficient compression to minimize file size, and enables very fast reads for analytic workloads.
NEW QUESTION # 74
Which of the following types of layers is used to downsample feature detection when using a convolutional neural network?
Answer: A
Explanation:
# Pooling layers are used in Convolutional Neural Networks (CNNs) to reduce the spatial dimensions (width and height) of the feature maps. This helps in downsampling, reducing computational complexity, and controlling overfitting by summarizing the features (e.g., max pooling or average pooling).
Why the other options are incorrect:
* B: Input layers receive raw data and do not perform downsampling.
* C: Output layers generate the final prediction.
* D: Hidden layers process data but do not specifically perform downsampling unless designed to do so (e.g., convolutional or pooling sublayers).
Official References:
* CompTIA DataX (DY0-001) Study Guide - Section 4.3:"Pooling layers are used to downsample feature maps and are critical in CNNs for reducing dimensions."

NEW QUESTION # 75
Which of the following is best solved with graph theory?
Answer: C
Explanation:
The traveling-salesman problem is a prototypical graph theory challenge, finding the shortest tour through a graph's nodes, whereas the other tasks rely on different domains (OCR on image processing, fraud detection often on statistical/anomaly methods, bandit problems on sequential decision theory).
NEW QUESTION # 76
A data scientist is building a proof of concept for a commercialized machine-learning model. Which of the following is the best starting point?
Answer: B
Explanation:
Before diving into selecting or tuning models, a literature review grounds the proof of concept in existing research and best practices, ensuring the approach aligns with state-of-the-art methods and the problem's domain requirements.
