質問 # 48
As a data scientist, you are working on a global health dataset that has data from more than 50 countries. You want to encode three features, such as 'countries', 'race', and 'body organ' as categories. Which option would you use to encode the categorical feature?
正解：D
解説：
Detailed Answer in Step-by-Step Solution:
* Objective: Encode categorical features in a Data Science context (likely ADS SDK).
* Understand Encoding: Converts categories (e.g., countries) to numerical forms.
* Evaluate Options:
* A: Not a standard ADS method-incorrect.
* B: General transformation, not specific encoding-incorrect.
* C: OneHotEncoder-Standard for categorical encoding-correct.
* D: Visualization, not encoding-incorrect.
* Reasoning: One-hot encoding creates binary columns-ideal for multiple categories.
* Conclusion: C is correct.
OCI documentation states: "In ADS SDK, use OneHotEncoder (C) from sklearn (or similar) to encode categorical features like 'countries' into binary vectors for modeling." A isn't real, B is too broad, D is unrelated-only C fits OCI's encoding practice.

質問 # 49
Which Oracle Accelerated Data Science (ADS) classes can be used for easy access to datasets from reference libraries and index websites such as scikit-learn?
正解：D
解説：
Detailed Answer in Step-by-Step Solution:
* Objective: Identify ADS class for dataset access (e.g., scikit-learn).
* Evaluate Options:
* A: DataLabeling-Not an ADS class.
* B: DatasetBrowser-Not real.
* C: SecretKeeper-Credentials, not data.
* D: DatasetFactory-Loads datasets (e.g., open())-correct.
* Reasoning: DatasetFactory simplifies library dataset access.
* Conclusion: D is correct.
OCI documentation states: "DatasetFactory (D) in ADS SDK accesses datasets from libraries like scikit-learn (e.g., DatasetFactory.open('sklearn.datasets:load_iris'))." A, B, and C don't exist or apply-only D fits.

質問 # 50
What happens when a notebook session is deactivated?
正解：A
解説：
Detailed Answer in Step-by-Step Solution:
* Understand Notebook Sessions: These are OCI compute instances running JupyterLab.
* Deactivation Impact: Deactivating stops the session to save costs.
* Evaluate Options:
* A: False-Costs decrease as compute stops.
* B: False-Boot volume data isn't preserved; block volume data is.
* C: True-The compute instance shuts down, halting billing.
* D: False-Block volume persists unless explicitly deleted.
* Reasoning: Deactivation stops the instance (C), preserving block volume data separately.
* Conclusion: C is correct.
The OCI documentation states: "When a notebook session is deactivated, the underlying compute instance stops, and billing for compute resources ceases. Data on the attached block volume is preserved, but the boot volume is not." A is backwards, B misattributes preservation, and D overstates deletion-only C aligns with the process.

質問 # 51
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?
正解：D
解説：
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-Handled by OCI settings, not score.py.
* B: Inference logic-Correct; runs load_model(), predict().
* C: Scaling-Set in deployment, not score.py.
* D: Dependencies-In runtime.yaml, not score.py.
* Reasoning: B aligns with score.py's execution role.
* Conclusion: B is correct.
OCI documentation states: "score.py (B) contains the inference logic, including functions to load the model and predict outputs, executed by the deployment endpoint." A, C, and D are managed elsewhere-only B matches OCI's design.

質問 # 52
Which type of firewalls are designed to protect against web application attacks, such as SQL injection and cross-site scripting?
正解：C
解説：
Detailed Answer in Step-by-Step Solution:
* Objective: Identify the firewall type protecting against web app attacks like SQL injection and XSS.
* Understand Firewall Types:
* Stateful Inspection: Tracks connection states, not app-specific.
* Web Application Firewall (WAF): Targets web app vulnerabilities.
* Incident Firewall: Not a recognized term.
* Packet Filtering: Basic packet rules, not app-aware.
* Evaluate Options:
* A: Stateful-General network, not web-specific-incorrect.
* B: WAF-Designed for SQLi, XSS-correct.
* C: Incident-Non-existent-incorrect.
* D: Packet-Low-level, not app-focused-incorrect.
* Reasoning: WAF specializes in web app security-matches requirement.
* Conclusion: B is correct.
OCI documentation states: "Web Application Firewall (WAF) (B) protects against web application attacks like SQL injection and cross-site scripting by inspecting HTTP traffic." A and D handle network-level threats, C isn't real-only B aligns with OCI's WAF purpose.
