Oracle Cloud Infrastructure 1z0-1110-25 Passing Score

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—visualization requires evaluation tools.

Evaluate Options:

A. EvaluationMetrics: Likely a typo—meant EvaluationsMetrics? Not a standalone class for visualization.

B. ADSEvaluator: Designed to evaluate and visualize model performance (e.g., ROC curves)—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: “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.” EvaluationMetrics (A) isn’t a class, ADSExplainer (C) focuses on interpretability, and ADSTuner (D) is for tuning—only B fits the visualization need per OCI’s ADS toolkit.

Detailed Answer in Step-by-Step Solution:

Objective: Prevent deployment failure due to utilization limits.

Understand Utilization: High load requires capacity or throttling.

Evaluate Options:

A: More instances—Scales horizontally—correct.

B: Delete—Stops service, not a fix—incorrect.

C: Fewer instances—Worsens issue—incorrect.

D: Larger VM—Scales vertically—correct.

E: Reduce bandwidth—Controls load—correct.

Reasoning: A and D increase capacity, E manages demand—effective trio.

Conclusion: A, D, E are correct.

OCI documentation states: “To avoid utilization limits, increase instances (A), use a larger compute shape (D), or reduce load balancer bandwidth (E) to manage request rates.” B stops service, C reduces capacity—only A, D, E align with OCI’s deployment scaling options.

Detailed Answer in Step-by-Step Solution:

Objective: Select an OCI AI service for text and table extraction from documents.

Evaluate Options:

A: Language—Text analysis, not extraction—incorrect.

B: Digital Assistant—Chatbots, not document tasks—incorrect.

C: Speech—Audio transcription, not documents—incorrect.

D: Vision—OCR for text/tables—correct.

Reasoning: Vision’s OCR extracts text and tables from document images.

Conclusion: D is correct.

OCI documentation states: “OCI Vision (D) uses OCR to extract text and tables from documents, supporting document analysis tasks.” A analyzes text post-extraction, B and C are unrelated—only D fits per OCI’s AI services.

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.
