                                  NEW QUESTION # 131
                                  Which components are a part of the OCI Identity and Access Management service?

                                  Answer: D

                                  Explanation:
                                  Detailed Answer in Step-by-Step Solution:
                                  Objective: Identify IAM components in OCI.
                                  Understand IAM: Manages access via policies, groups, etc.
                                  Evaluate Options:
                                  A: Policies&#x2014;Core IAM component&#x2014;correct.
                                  B: Subnets&#x2014;Networking, not IAM.
                                  C: Instances&#x2014;Compute, not IAM.
                                  D: VCN&#x2014;Networking, not IAM.
                                  Reasoning: Only A is an IAM element&#x2014;others are resources.
                                  Conclusion: A is correct.
                                  OCI documentation states: &#x201C;IAM includes components like policies (A), groups, and compartments to control resource access.&#x201D; B, C, and D are infrastructure, not IAM&#x2014;only A fits per OCI&#x2019;s IAM framework.

                                  NEW QUESTION # 132
                                  Which of the following TWO non-open source JupyterLab extensions has Oracle Cloud Infrastructure (OCI) Data Science developed and added to the notebook session experience?

                                  Answer: C,E

                                  Explanation:
                                  Detailed Answer in Step-by-Step Solution:
                                  Objective: Identify two OCI-developed, non-open-source JupyterLab extensions.
                                  Understand Extensions: OCI enhances JupyterLab with proprietary tools.
                                  Evaluate Options:
                                  A: Environment Explorer&#x2014;OCI-specific, non-open&#x2014;correct.
                                  B: Table of Contents&#x2014;Open-source Jupyter&#x2014;incorrect.
                                  C: Command Palette&#x2014;Open-source Jupyter&#x2014;incorrect.

                                  E: Terminal&#x2014;Open-source Jupyter&#x2014;incorrect.
                                  Reasoning: A and D are OCI proprietary; others are standard JupyterLab.
                                  Conclusion: A and D are correct.
                                  OCI documentation states: &#x201C;OCI Data Science adds non-open-source extensions like Environment Explorer (A) for conda management and Notebook Examples (D) for sample code&#x2014;both proprietary enhancements.&#x201D; B, C, and E are open-source JupyterLab defaults&#x2014;only A and D are OCI-specific per the notebook session design.

                                  NEW QUESTION # 133
                                  What is a common maxim about data scientists?

                                  Answer: A

                                  Explanation:
                                  Detailed Answer in Step-by-Step Solution:
                                  Objective: Identify a widely accepted maxim about data scientists&#x2019; time allocation.
                                  Understand Data Science Workflow: Involves data collection, preparation, and analysis&#x2014;time distribution is key.
                                  Evaluate Options:
                                  A: 80% on finding/preparing, 20% analyzing&#x2014;Reflects the data wrangling challenge.
                                  B: 80% analyzing, 20% finding/preparing&#x2014;Inverts the common perception.
                                  C: 80% on failed projects, 20% useful&#x2014;Pessimistic, not a standard maxim.
                                  Reasoning: Industry consensus (e.g., &#x201C;80/20 rule&#x201D;) emphasizes data prep as the bulk of effort due to messy real-world data.
                                  Conclusion: A is correct.
                                  OCI Data Science documentation aligns with industry norms: &#x201C;Data scientists typically spend 80% of their time finding, cleaning, and preparing data, and 20% on analysis and modeling, due to the complexity of raw data.&#x201D; B reverses this, and C isn&#x2019;t supported&#x2014;only A reflects this widely cited maxim from sources like Forbes and OCI&#x2019;s practical guidance.

                                  NEW QUESTION # 134
                                  You are a data scientist; you use the Oracle Cloud Infrastructure (OCI) Language service to train custom models. Which types of custom models can be trained?

                                  Answer: C

                                  Explanation:
                                  Detailed Answer in Step-by-Step Solution:
                                  Objective: Identify custom model types for OCI Language.
                                  Understand OCI Language: Focuses on text analysis.
                                  Evaluate Options:
                                  A: Image classification&#x2014;Not text-based, incorrect.
                                  B: Text classification, NER&#x2014;Both text tasks&#x2014;correct.
                                  C: Sentiment, NER&#x2014;Sentiment is pretrained, not custom.
                                  D: Object detection&#x2014;Image-based, incorrect.
                                  Reasoning: B aligns with OCI Language&#x2019;s text custom models.
                                  Conclusion: B is correct.
                                  OCI Language documentation states: &#x201C;Custom models can be trained for text classification and Named Entity Recognition (NER) using your data.&#x201D; Image tasks (A, D) are for Vision, and sentiment (C) is pretrained&#x2014;only B fits OCI Language&#x2019;s scope.

                                  NEW QUESTION # 135
                                  What is the first step in the data science process?

                                  Answer: C

                                  Explanation:
                                  Detailed Answer in Step-by-Step Solution:
                                  Objective: Identify the initial data science step.
                                  Define Process: Starts with problem definition, then data and modeling.
                                  Evaluate Options:
                                  A: Data collection&#x2014;Second step after problem definition.
                                  B: Modeling&#x2014;Later stage.
                                  C: Hypothesis&#x2014;Sets the goal, first step&#x2014;correct.
                                  D: Data owners&#x2014;Collaboration, not the start.
                                  Reasoning: Hypothesis drives the process (e.g., &#x201C;Can we predict churn?&#x201D;).
                                  Conclusion: C is correct.
                                  OCI documentation states: &#x201C;The data science process begins with defining an analytical hypothesis to address a business problem, followed by data collection and analysis.&#x201D; C precedes A, B, and D&#x2014;aligning with OCI&#x2019;s structured approach.
