What is the minimum active storage duration for logs used by Logging Analytics to be archived?
Correct Answer: C
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. Oracle Cloud Infrastructure Logging Analytics Documentation, "Log Retention".
1z0-1110-25 Exam Question 2
You are attempting to save a model from a notebook session to the model catalog by using the Accelerated Data Science (ADS) SDK, with resource principal as the authentication signer, and you get a 404 authentication error. Which two should you look for to ensure permissions are set up correctly?
Correct Answer: B,D
Detailed Answer in Step-by-Step Solution: * Objective: Troubleshoot a 404 auth error when saving a model with resource principal. * Understand Resource Principal: Allows notebook sessions to act as principals via dynamic groups and policies-no user credentials. * Analyze 404 Error: Indicates permission failure-likely IAM misconfiguration. * Evaluate Options: * A: Block volume storage-Irrelevant to auth; it's about saving locally-incorrect. * B: Dynamic group matching-Ensures notebook is recognized-correct. * C: User group policy-Not used with resource principal-incorrect. * D: Dynamic group policy-Grants catalog access-correct. * E: Service Gateway-Network-related, not auth-specific-incorrect. * Reasoning: Resource principal needs B (group inclusion) and D (policy perms)-404 points to these. * Conclusion: B and D are correct. OCI documentation states: "For ADS SDK to save to the Model Catalog using resource principal, ensure (1) a dynamic group includes notebook sessions with matching rules (e.g., resource.type ='datasciencenotebooksession') (B), and (2) a policy grants manage data-science-models to that dynamic group (D)." A is storage, C is user-based, E is network-only B and D fix the auth issue per OCI's IAM setup. Oracle Cloud Infrastructure Data Science Documentation, "Resource Principal with Model Catalog".

You want to write a Python script to create a collection of different projects for your data science team. Which Oracle Cloud Infrastructure (OCI) Data Science interface would you use?
Correct Answer: A
Detailed Answer in Step-by-Step Solution: * Objective: Choose an interface for a Python script to manage projects. * Evaluate Options: * A: OCI SDK-Python-based, scriptable-correct. * B: Console-GUI, not scriptable. * C: CLI-Command-based, not Python-native. * D: Mobile App-Not for scripting. * Reasoning: A enables programmatic project creation. * Conclusion: A is correct. OCI documentation states: "Use the OCI Python SDK (A) to programmatically manage Data Science resources, like creating projects, via Python scripts." B, C, and D don't support Python scripting-only A fits. Oracle Cloud Infrastructure SDK Documentation, "Data Science API".
1z0-1110-25 Exam Question 4
As a data scientist, you use the Oracle Cloud Infrastructure (OCI) Language service to train custommodels. Which types of custom models can be trained?
Correct Answer: B
Detailed Answer in Step-by-Step Solution: * Objective: Identify custom model types for OCI Language service. * Understand OCI Language: Focuses on text analysis, not images. * Evaluate Options: * A: Image classification-Incorrect; Language is text-based. * B: Text classification, NER-Both text tasks-correct. * C: Sentiment-Pretrained, not custom; NER ok-incorrect. * D: Object detection-Image-based, incorrect. * Reasoning: B aligns with OCI Language's custom text capabilities. * Conclusion: B is correct. OCI documentation states: "OCI Language supports training custom models for text classification and Named Entity Recognition (NER) (B) using user data." A and D involve images, C includes pretrained sentiment- only B matches OCI Language's custom model scope. Oracle Cloud Infrastructure Language Documentation, "Custom Model Types".
1z0-1110-25 Exam Question 5
You realize that your model deployment is about to reach its utilization limit. What would you do to avoid the issue before requests start to fail? Which THREE steps would you perform?
Correct Answer: A,D,E
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. Oracle Cloud Infrastructure Data Science Documentation, "Model Deployment Scaling".
