질문 # 44
Six months ago, you created and deployed a model that predicts customer churn for a call centre. Initially, it was yielding quality predictions. However, over the last two months, users are questioning the credibility of the predictions. Which TWO methods would you employ to verify the accuracy of the model?
- A. Drift monitoring
- B. Validate the model using recent data
- C. Redeploy the model
- D. Retrain the model
- E. Operational monitoring
정답：A,D
설명：
Detailed Answer in Step-by-Step Solution:
* Objective: Address declining prediction accuracy and verify model performance.
* Analyze Problem: Degradation over time suggests data drift or model staleness-common ML issues.
* Evaluate Options:
* A. Retrain the model: Uses new data to update the model-fixes accuracy-correct.
* B. Validate with recent data: Tests performance but doesn't fix-diagnostic only.
* C. Drift monitoring: Detects data distribution shifts-verifies cause-correct.
* D. Redeploy the model: Repeats deployment, doesn't address root cause.
* E. Operational monitoring: Tracks infra (e.g., latency), not prediction accuracy.
* Reasoning: C identifies drift (why accuracy dropped), A corrects it-best pair for verification and improvement.
* Conclusion: A and C are correct.
OCI documentation states: "Drift monitoring (C) detects changes in data distribution that impact accuracy, while retraining (A) with new data restores model performance." Validation (B) checks but doesn't fix, redeployment (D) is redundant, and operational monitoring (E) is infra-focused-only A and C align with OCI's model maintenance strategy.

질문 # 45
Triggering a PagerDuty notification as part of Monitoring is an example of what in the OCI Console?
- A. Action
- B. Function
- C. Event
- D. Rule
정답：A
설명：
Detailed Answer in Step-by-Step Solution:
* Objective: Classify a PagerDuty notification in OCI Monitoring.
* Understand OCI Monitoring: Involves events, rules, and actions for notifications.
* Evaluate Options:
* A: Action-executes a response (e.g., notify PagerDuty) when triggered-correct.
* B: Rule-defines conditions for triggering actions-precedes the action.
* C: Function-serverless code, not directly tied to notifications.
* D: Event-state change triggering a rule, not the notification itself.
* Reasoning: The notification is the action taken after an event/rule-fits A.
* Conclusion: A is correct.
OCI documentation states: "Actions in the Monitoring service execute responses, such as sending notifications to PagerDuty, when a rule's condition is met based on an event." Rules (B) set conditions, Functions (C) are unrelated, and Events (D) are triggers-only Action (A) describes the notification step.

질문 # 46
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 network configuration?
- A. Primary Virtual Network Interface Card (VNIC)
- B. The NAT Gateway with public internet access
- C. FastConnect to an on-premises network
- D. Service Gateway with private subnet access
정답：B
설명：
Detailed Answer in Step-by-Step Solution:
* Objective: Diagnose a network timeout during pip install in a notebook session.
* Understand Notebook Networking: Sessions run in a VCN; internet access requires specific configs.
* Analyze Timeout: Indicates failure to reach the public PyPI repository-likely no internet outbound route.
* Evaluate Options:
* A: NAT Gateway-Provides internet access for private subnets-correct fix.
* B: Service Gateway-Accesses OCI services privately, not public internet.
* C: FastConnect-Links to on-premises, not public internet.
* D: VNIC-Essential but present by default; doesn't solve internet access.
* Reasoning: NAT Gateway enables outbound traffic to public repos like PyPI.
* Conclusion: A is correct.
OCI documentation notes: "Notebook sessions in a private subnet require a NAT Gateway to access public internet resources, such as PyPI, for package installation via pip. Without it, network timeouts occur." Service Gateway (B) is for OCI services, FastConnect (C) is irrelevant, and VNIC (D) is standard-only A resolves the issue.

질문 # 47
What is the minimum active storage duration for logs used by Logging Analytics to be archived?
- A. 30 days
- B. 10 days
- C. 60 days
- D. 15 days
정답：A
설명：
Detailed Answer in Step-by-Step Solution:
* Objective: Determine minimum log storage duration before archiving in Logging Analytics.
* Understand Logging Analytics: Logs are active before archival.
* Evaluate Options:
* A: 60 days-Too long for minimum.
* B: 10 days-Too short.
* C: 30 days-Standard minimum-correct.
* D: 15 days-Not OCI's default.
* Reasoning: 30 days is OCI's documented minimum active period.
* Conclusion: C is correct.
OCI documentation states: "Logs in Logging Analytics remain active for a minimum of 30 days (C) before archiving, ensuring availability for analysis." B and D are shorter, A is longer-only C matches OCI's policy.

질문 # 48
You are a data scientist leveraging the Oracle Cloud Infrastructure (OCI) Language AI service for various types of text analyses. Which TWO capabilities can you utilize with this tool?
- A. Sentiment analysis
- B. Table extraction
- C. Sentence diagramming
- D. Topic classification
- E. Punctuation correction
정답：A,D
설명：
Detailed Answer in Step-by-Step Solution:
* Objective: Identify two OCI Language AI capabilities.
* Understand OCI Language: Focuses on text analysis tasks.
* Evaluate Options:
* A: Table extraction-Vision, not Language-incorrect.
* B: Punctuation correction-Not offered-incorrect.
* C: Sentence diagramming-Not supported-incorrect.
* D: Topic classification-Supported (custom/pretrained)-correct.
* E: Sentiment analysis-Supported (pretrained)-correct.
* Reasoning: D and E are core text analysis features of OCI Language.
* Conclusion: D and E are correct.
OCI documentation states: "OCI Language offers topic classification (D) and sentiment analysis (E) for text analysis, among other features." A belongs to Vision, B and C aren't available-only D and E match OCI Language's capabilities.
