Oracle Cloud Infrastructure 2025 Data Science Professional Sample Questions (Q56-Q61):

NEW QUESTION # 56
As a data scientist, you are trying to automate a machine learning (ML) workflow and have decided to use Oracle Cloud Infrastructure (OCI) AutoML Pipeline. Which THREE are part of the AutoML Pipeline?

A. Algorithm Selection
B. Adaptive Sampling
C. Feature Selection
D. Feature Extraction
E. Model Deployment

Answer: A,B,C

Explanation:
Detailed Answer in Step-by-Step Solution:
* Objective: Identify three stages in OCI AutoML Pipeline.
* Understand Pipeline: Automates ML steps from data to model training.
* Evaluate Options:
* A: Feature Selection-Selects relevant features-correct.
* B: Adaptive Sampling-Reduces data size-correct.
* C: Model Deployment-Post-pipeline step-incorrect.
* D: Feature Extraction-Not explicit in OCI AutoML-incorrect.
* E: Algorithm Selection-Chooses best model-correct.
* Reasoning: A, B, E are core automated stages; C and D are separate.
* Conclusion: A, B, E are correct.
OCI documentation lists "AutoML Pipeline stages as adaptive sampling (B), feature selection (A), algorithm selection (E), and hyperparameter tuning." Deployment (C) is post-pipeline, and extraction (D) isn't highlighted-only A, B, E are included per OCI's design.
Oracle Cloud Infrastructure AutoML Documentation, "Pipeline Components".

NEW QUESTION # 57
Which statement best describes Oracle Cloud Infrastructure Data Science Jobs?

A. Jobs let you define and run repeatable tasks on customer-managed infrastructure.
B. Jobs let you define and run repeatable tasks on fully managed infrastructure.
C. Jobs let you define and run all Oracle Cloud DevOps workloads.
D. Jobs let you define and run repeatable tasks on fully managed third-party cloud infrastructures.

Answer: B

Explanation:
Detailed Answer in Step-by-Step Solution:
* Understand OCI Data Science Jobs: This service automates ML tasks (e.g., training, evaluation) with configurable, repeatable executions.
* Key Characteristics: Jobs run on OCI's infrastructure, managed by Oracle, not the customer or third parties, and are specific to Data Science, not general DevOps.
* Evaluate Options:
* A: Correct-Jobs are defined by users (e.g., via scripts) and executed on OCI's fully managed compute resources.
* B: Incorrect-Infrastructure is managed by OCI, not the customer.
* C: Incorrect-No third-party cloud integration; it's OCI-specific.
* D: Incorrect-Jobs are for Data Science tasks (e.g., ML training), not all DevOps workloads (e.
g., CI/CD pipelines).
* Reasoning: "Fully managed" means OCI handles provisioning and scaling, aligning with A.
* Conclusion: A accurately reflects the service's purpose and operation.
OCI Data Science Jobs "allow users to define and execute repeatable machine learning tasks, such as model training or batch processing, on fully managed OCI infrastructure." This eliminates customer management (B), third-party clouds (C), or broad DevOps scope (D). The documentation emphasizes automation and management by OCI, making A the precise description.
Oracle Cloud Infrastructure Data Science Documentation, "Overview of Jobs" section.

NEW QUESTION # 58
Which activity is NOT a part of the machine learning life cycle?

A. Data Access
B. Modeling
C. Database Management
D. Model Deployment

Answer: C

Explanation:
Detailed Answer in Step-by-Step Solution:
* Objective: Identify which activity isn't part of the ML lifecycle.
* Define ML Lifecycle: Includes data access, preparation, modeling, evaluation, deployment, and monitoring.
* Evaluate Options:
* A: Database Management (e.g., DBA tasks) is IT-related, not specific to ML workflows.
* B: Model Deployment (e.g., serving predictions) is a key ML phase-correctly included.
* C: Modeling (e.g., training) is the core of ML-correctly included.
* D: Data Access (e.g., retrieving data) is the first ML step-correctly included.
* Reasoning: Database management supports infrastructure, not the ML process directly.
* Conclusion: A is the outlier.
The OCI Data Science lifecycle includes "data access, exploration, feature engineering, modeling, deployment, and monitoring," per the documentation. Database Management (A) is a general ITtask (e.g., optimizing Oracle DB), not an ML-specific activity, unlike B, C, and D, which are integral to OCI's ML pipeline.
Oracle Cloud Infrastructure Data Science Documentation, "Machine Learning Lifecycle Overview".

NEW QUESTION # 59
Which model has an open-source, open model format that allows you to run machine learning models on different platforms?

A. TensorFlow
B. ONNX
C. PySpark
D. PyTorch

Answer: B

Explanation:
Detailed Answer in Step-by-Step Solution:
* Objective: Identify an open model format for cross-platform ML model execution.
* Evaluate Options:
* A. PySpark: A big data framework, not a model format.
* B. PyTorch: An ML framework with its own format, not inherently cross-platform without conversion.
* C. TensorFlow: An ML framework with its SavedModel format, not universally open across platforms.
* D. ONNX: Open Neural Network Exchange, an open-source format for model interoperability across frameworks.
* Reasoning: ONNX is designed for portability (e.g., convert PyTorch to ONNX, run in TensorFlow), unlike framework-specific options.
* Conclusion: D is the correct choice.
ONNX (D) is "an open-source model format that enables interoperability between ML frameworks like PyTorch and TensorFlow," per OCI documentation. PySpark (A) is a processing tool, while PyTorch (B) and TensorFlow (C) are frameworks with native formats-only ONNX ensures cross-platform compatibility.
Oracle Cloud Infrastructure Data Science Documentation, "Supported Model Formats".

NEW QUESTION # 60
You want to build a multistep machine learning workflow by using the Oracle Cloud Infrastructure (OCI) Data Science Pipeline feature. How would you configure the conda environment to run a pipeline step?

A. Configure a block volume
B. Configure a compute shape
C. Use command-line variables
D. Use environmental variables

Answer: D

Explanation:
Detailed Answer in Step-by-Step Solution:
* Objective: Configure conda env for a pipeline step.
* Evaluate Options:
* A: Shape-Infra, not env config.
* B: Volume-Storage, not env.
* C: Command-line-Step args, not env.
* D: Env variables-Sets conda path-correct.
* Reasoning: D specifies runtime env (e.g., CONDA_ENV_SLUG).
* Conclusion: D is correct.
OCI documentation states: "Configure a pipeline step's conda environment using environment variables (D), such as CONDA_ENV_SLUG, in the step definition." A, B, and C address other aspects-only D fits env config.
Oracle Cloud Infrastructure Data Science Documentation, "Pipeline Step Configuration".
