Oracle Cloud Infrastructure Data Science Professional Sample Questions (Q11-Q16):

NEW QUESTION # 11
You have built a machine model to predict whether a bank customer is going to default on a loan. You want to use Local Interpretable Model-Agnostic Explanations (LIME) to understand a specific prediction. What is the key idea behind LIME?

Answer: C

Explanation:
Detailed Answer in Step-by-Step Solution:
Objective: Define LIME&#x2019;s core concept.
Understand LIME: Explains individual predictions with local surrogate models.
Evaluate Options:
A: Complex global, simple local&#x2014;Correct LIME principle.
B: Agnosticism&#x2014;True but not the key idea.
C: Global/local similarity&#x2014;False.
D: Local vs. global agnosticism&#x2014;Incorrect distinction.
Reasoning: A captures LIME&#x2019;s local approximation focus.
Conclusion: A is correct.
OCI documentation notes: &#x201C;LIME (A) explains predictions by approximating complex global models with simpler local surrogate models around specific instances.&#x201D; B, C, and D misalign&#x2014;only A reflects LIME&#x2019;s foundational idea per OCI&#x2019;s interpretability tools.

NEW QUESTION # 12
You loaded data into Oracle Cloud Infrastructure (OCI) Data Science. To transform the data, you want to use the Accelerated Data Science (ADS) SDK. When you applied the get_recommendations() tool to the ADSDataset object, it showed you user-detected issues with all the recommended changes to apply to the dataset. Which option should you use to apply all the recommended transformations at once?

Answer: D

Explanation:
Detailed Answer in Step-by-Step Solution:
Objective: Apply all recommended transformations from get_recommendations() in ADS.
Understand ADS Tools: get_recommendations() suggests fixes (e.g., missing values).
Evaluate Options:
A: Returns transformed data&#x2014;Not for applying&#x2014;incorrect.
B: Sklearn-style, not ADS-specific&#x2014;incorrect.
C: auto_transform()&#x2014;Applies all recommendations&#x2014;correct.
D: Visualizes, doesn&#x2019;t apply&#x2014;incorrect.
Reasoning: auto_transform() executes the fixes suggested by get_recommendations().
Conclusion: C is correct.
OCI documentation states: &#x201C;After get_recommendations() identifies issues, use auto_transform() (C) on the ADSDataset to apply all recommended transformations at once.&#x201D; A retrieves, B is external, D visualizes&#x2014;only C aligns with OCI&#x2019;s ADS transformation workflow.

NEW QUESTION # 13
When preparing your model artifact to save it to the Oracle Cloud Infrastructure (OCI) DataScience model catalog, you create a score.py file. What is the purpose of the score.py file?

Answer: D

Explanation:
Detailed Answer in Step-by-Step Solution:
Objective: Define the role of score.py in OCI model artifacts.
Understand Artifacts: score.py is key for deployment runtime.
Evaluate Options:
A: Infra config&#x2014;Handled by OCI settings, not score.py.
B: Inference logic&#x2014;Correct; runs load_model(), predict().
C: Scaling&#x2014;Set in deployment, not score.py.
D: Dependencies&#x2014;In runtime.yaml, not score.py.
Reasoning: B aligns with score.py&#x2019;s execution role.
Conclusion: B is correct.
OCI documentation states: &#x201C;score.py (B) contains the inference logic, including functions to load the model and predict outputs, executed by the deployment endpoint.&#x201D; A, C, and D are managed elsewhere&#x2014;only B matches OCI&#x2019;s design.

NEW QUESTION # 14
Which cache rules criterion matches if the concatenation of the requested URL path and query are identical to the contents of the value field?

Answer: D

Explanation:
Detailed Answer in Step-by-Step Solution:
Objective: Match a cache rule criterion for exact URL path and query.
Understand Cache Rules: Used in OCI (e.g., WAF, CDN) to cache content.
Evaluate Options:
A: Contains&#x2014;Partial match, not exact.
B: Is&#x2014;Exact match of full URL (path + query)&#x2014;correct.
C: Ends with&#x2014;Matches end, not full URL.
D: Starts with&#x2014;Matches start, not full URL.
Reasoning: &#x201C;URL_IS&#x201D; checks exact equality&#x2014;fits requirement.
Conclusion: B is correct.
OCI documentation states: &#x201C;The URL_IS (B) criterion in cache rules matches when the full URL (path and query) exactly equals the specified value.&#x201D; A, C, and D are partial matches&#x2014;only B ensures identical concatenation per OCI&#x2019;s caching config.

NEW QUESTION # 15
You are a data scientist working inside a notebook session and you attempt to pip install a package from a public repository that is not included in your conda environment. After running this command, you get a network timeout error. What might be missing from your networking configuration?

Answer: C

Explanation:
Detailed Answer in Step-by-Step Solution:
Objective: Fix network timeout for pip install in a notebook.
Evaluate Options:
A: FastConnect&#x2014;On-premises link, not public internet.
B: VNIC&#x2014;Default, not the issue.
C: NAT Gateway&#x2014;Grants internet access&#x2014;correct.
D: Service Gateway&#x2014;OCI services, not PyPI.
Reasoning: C enables outbound traffic to public repos.
Conclusion: C is correct.
OCI documentation states: &#x201C;A NAT Gateway (C) is required for notebook sessions in private subnets to access public internet repositories like PyPI.&#x201D; A, B, and D don&#x2019;t provide this&#x2014;only C resolves the timeout.
