Try these sample questions before moving to the full interactive quiz below. Each question includes the correct answer and explanation to help you understand the concepts tested in a 1Z0-1110-25: Oracle Cloud Infrastructure 2025 Data Science Professional exam.

1 A bike sharing platform has collected user commute data for the past 3 years. For increasing profitability and making useful inferences, a machine learning model needs to be built from the accumulated data. Which of the following options has the correct order of the required machine learning tasks for building a model?

A Data Access, Feature Exploration, Data Exploration, Feature Engineering, Modeling
B Data Access, Data Exploration, Feature Exploration, Feature Engineering, Modeling
C Data Access, Data Exploration, Feature Engineering, Feature Exploration, Modeling
D Data Access, Feature Exploration, Feature Engineering, Data Exploration, Modeling
Answer: C
Detailed Answer in Step-by-Step Solution: Data Access: The first step in any machine learning workflow is accessing the raw data. This involves retrieving the user commute data collected over the past 3 years from the bike-sharing platform’s storage system. Data Exploration: Once data is accessed, it’s explored to understand its structure, quality, and patterns (e.g., missing values, distributions). This step helps identify what preprocessing is needed. Feature Engineering: After understanding the data, features are created or transformed (e.g., commute duration, time of day) to improve model performance. This step precedes feature exploration because you need engineered features to analyze further. Feature Exploration: This involves analyzing the engineered features (e.g., correlation analysis, importance ranking) to refine them or select the most relevant ones for modeling. Modeling: Finally, the prepared data and features are used to train and evaluate a machine learning model. Option C (Data Access, Data Exploration, Feature Engineering, Feature Exploration, Modeling) follows this logical sequence, aligning with standard ML workflows. The correct order reflects the machine learning lifecycle as outlined in Oracle’s OCI Data Science documentation. Data Access is the initial step to retrieve data, followed by Data Exploration to assess it (e.g., using OCI Data Science Notebook Sessions with tools like pandas). Feature Engineering transforms raw data into meaningful inputs, followed by Feature Exploration to analyze feature importance (e.g., using ADS SDK’s correlation tools). Modeling is the final step where the model is built and trained. This sequence is consistent with Oracle’s recommended practices for building ML models in OCI Data Science (Reference: Oracle Cloud Infrastructure Data Science Service Documentation, "Machine Learning Lifecycle").

2 Which TWO statements about Oracle Cloud Infrastructure (OCI) Open Data service are true?

A Open Data includes text and image data repositories for AI and ML.
B Audio and video formats are not available.
C Each dataset in Open Data consists of code and tooling usage examples for consumption and reproducibility.
D Open Data is a dataset repository made for the people that create, use, and manipulate datasets.
E A primary goal of Open Data is for users to contribute to the data repositories to expand the content offered.
F Subscribers can pay and log into Open Data to view curated datasets that are otherwise not available to the public.
Answer: A, D
Detailed Answer in Step-by-Step Solution: Analyze OCI Open Data: OCI Open Data is a free service providing access to public datasets for AI/ML use cases. Evaluate Statements: A: True—Open Data includes text and image datasets (e.g., geospatial images). B: False—Video and other formats may be available depending on the dataset; no strict exclusion exists. C: False—Datasets may include metadata, but code/tooling examples aren’t guaranteed. D: True—It’s designed for data scientists and analysts who work with datasets. E: False—It’s not a user-contributed repository; it’s curated by Oracle. F: False—Open Data is free and public, not subscription-based. Select Two: A and D align with the service’s purpose and offerings. OCI Open Data provides access to datasets like text and images (A) for AI/ML, aimed at data professionals (D). It’s a free, curated service, not user-contributed (E) or paid (F), and while it focuses on certain formats, it doesn’t explicitly exclude audio/video (B).
