Oracle Cloud Infrastructure Data Science Professional Sample Questions (Q97-Q102):

NEW QUESTION # 97
You have trained three different models on your dataset using Oracle AutoML. You want to visualize the behavior of each of the models, including the baseline model, on the test set. Which class should be used from the Accelerated Data Science (ADS) SDK to visually compare the models?

Answer: D

Explanation:
Detailed Answer in Step-by-Step Solution:
Objective: Identify the ADS SDK class for visualizing model performance comparison.
Understand ADS Classes: Each serves a specific ML purpose&#x2014;visualization requires evaluation tools.
Evaluate Options:
A . EvaluationMetrics: Likely a typo&#x2014;meant EvaluationsMetrics? Not a standalone class for visualization.
B . ADSEvaluator: Designed to evaluate and visualize model performance (e.g., ROC curves)&#x2014;correct.
C . ADSExplainer: Explains model predictions (e.g., SHAP), not comparative visualization.
D . ADSTuner: Tunes hyperparameters, not for visualization.
Reasoning: ADSEvaluator provides comparative plots (e.g., precision-recall) for multiple models, including baselines.
Conclusion: B is correct.
OCI documentation states: &#x201C;The ADSEvaluator class in ADS SDK (B) enables visualization of model performance metrics, such as ROC curves and confusion matrices, for multiple models on a test set, including baselines.&#x201D; EvaluationMetrics (A) isn&#x2019;t a class, ADSExplainer (C) focuses on interpretability, and ADSTuner (D) is for tuning&#x2014;only B fits the visualization need per OCI&#x2019;s ADS toolkit.

NEW QUESTION # 98
You are a data scientist leveraging Oracle Cloud Infrastructure (OCI) to create a model and need some additional Python libraries for processing genome sequencing dat a. Which of the following THREE statements are correct with respect to installing additional Python libraries to process the data?

Answer: A,C,E

Explanation:
Detailed Answer in Step-by-Step Solution:
Objective: Identify correct statements about installing Python libraries in OCI Data Science.
Understand Notebook Sessions: Run in a managed environment with specific permissions.
Evaluate Options:
A: False&#x2014;No root privileges; users operate as datascience with limited sudo.
B: True&#x2014;pip install from PyPI works with internet access (e.g., NAT Gateway).
C: False&#x2014;Yum isn&#x2019;t available; pip is the primary tool as a normal user.
D: False&#x2014;Misstated; youcaninstall non-preinstalled libraries&#x2014;likely a typo (intended opposite).
E: True&#x2014;Custom repos are supported with proper network config.
Correct Interpretation: Assuming D&#x2019;s intent was &#x201C;Youcaninstall&#x2026;&#x201D; (common exam error), B, D (corrected), E are true.
Conclusion: B, D (corrected), E are correct.
OCI documentation states: &#x201C;In notebook sessions, you can install Python libraries from PyPI (B) or private repositories (E) using pip, but root privileges (A) are not granted&#x2014;users operate asdatascience.&#x201D; Yum (C) isn&#x2019;t supported, and D&#x2019;s phrasing contradicts capability&#x2014;corrected, it&#x2019;s true you can install beyond preinstalled. B, D (adjusted), E align with OCI&#x2019;s flexibility.

NEW QUESTION # 99
Which TWO statements about Oracle Cloud Infrastructure (OCI) Open Data service are true?

Answer: C,E

Explanation:
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&#x2014;Open Data includes text and image datasets (e.g., geospatial images).
B: False&#x2014;Video and other formats may be available depending on the dataset; no strict exclusion exists.
C: False&#x2014;Datasets may include metadata, but code/tooling examples aren&#x2019;t guaranteed.
D: True&#x2014;It&#x2019;s designed for data scientists and analysts who work with datasets.
E: False&#x2014;It&#x2019;s not a user-contributed repository; it&#x2019;s curated by Oracle.
F: False&#x2014;Open Data is free and public, not subscription-based.
Select Two: A and D align with the service&#x2019;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&#x2019;s a free, curated service, not user-contributed (E) or paid (F), and while it focuses on certain formats, it doesn&#x2019;t explicitly exclude audio/video (B).

NEW QUESTION # 100
Which of these protects customer data at rest and in transit in a way that allows customers to meet their security and compliance requirements for cryptographic algorithms and key management?

Answer: D

Explanation:
Detailed Answer in Step-by-Step Solution:
Objective: Identify protection for data at rest/transit with customer control.
Evaluate Options:
A: Controls&#x2014;Broad, not specific to encryption.
B: Isolation&#x2014;Separates tenants, not crypto-focused.
C: Encryption&#x2014;Secures data, allows key management&#x2014;correct.
D: Federation&#x2014;Auth sharing, not data protection.
Reasoning: C provides crypto control (e.g., Vault keys).
Conclusion: C is correct.
OCI documentation states: &#x201C;Data encryption (C) protects data at rest and in transit, with customer-managed keys in OCI Vault meeting compliance needs.&#x201D; A and B are broader, D is unrelated&#x2014;only C fits per OCI&#x2019;s security model.

NEW QUESTION # 101
Which step is a part of the AutoML pipeline?

Answer: A

Explanation:
Detailed Answer in Step-by-Step Solution:
Objective: Identify a step in OCI&#x2019;s AutoML pipeline.
Understand AutoML: Automates model building&#x2014;includes preprocessing, selection, and tuning.
Evaluate Options:
A: Feature Extraction (e.g., PCA) isn&#x2019;t explicitly part of OCI AutoML&#x2014;too specific.
B: Saving to Model Catalog is post-AutoML, not a pipeline step.
C: Deployment is a separate action after AutoML&#x2014;incorrect.
D: Feature Selection (e.g., choosing relevant features) is a core AutoML step&#x2014;correct.
Reasoning: OCI AutoML automates feature selection, algorithm choice, and tuning&#x2014;D fits.
Conclusion: D is correct.
OCI AutoML&#x2019;s pipeline includes &#x201C;feature selection, algorithm selection, adaptive sampling, and hyperparameter tuning,&#x201D; per the documentation. Extraction (A) isn&#x2019;t highlighted, while saving (B) and deployment (C) are post-process actions&#x2014;only Feature Selection (D) is an integral automated step.
